Novel Target for GU Cancer Metastasis and TherapeuticsCancer progression is shaped by both cell-intrinsic adaptations and complex extrinsic interactions within the tumor microenvironment (TME). Here, we identify a transmembrane protein, Meta1, as a shared therapeutic target that exhibits a Janus-like role: promoting malignant phenotypes in cancer cells while restraining tumor-supportive functions in non-cancerous stromal and immune cells. Meta1 is expressed in both compartments of the TME, orchestrating a dual program that supports metastasis and immune evasion. Mechanistically, we uncovered a malignancy-promoting factor (MPF) that acts as a functional ligand for Meta1, selectively enhancing pro-invasive signaling in cancer cells. We further identify Meta1 as an unconventional G protein–coupled receptor (GPCR) that plays as an accelerator in cancer cells of the TME. Meta1 interacts with Rho-GDI and Gαq to activate RhoA-mediated cytoskeletal remodeling and amoeboid migration, facilitating metastatic dissemination. We further identify MPF binding to Meta1 initiates Gβγ signaling, elevating intracellular cAMP and activating Rap1, thereby amplifying cell motility and metastatic potential. Leveraging the Meta1–MPF interaction, we designed MPF-derived peptides that specifically bind Meta1 and serve as the basis for a novel peptide-based PROTAC, which efficiently induces degradation of Meta1 and abrogates its pro-metastatic functions. Our study unveils Meta1 as an atypical GPCR with canonical signaling capacity and topological divergence, representing a shared and targetable vulnerability that bridges cancer cell-intrinsic adaptation with extrinsic TME communication. These findings establish the Meta1–MPF axis as a compelling therapeutic target for suppressing metastasis and reprogramming the TME.

Reflecting on the Past, Shaping the Present, and Envisioning the Future of UAASince 1990, the Urological Association of Asia (UAA) has stood as a beacon of collaboration, innovation, and advancement in urology in Asia. As we reflect on its evolution, acknowledge its current impact, and envision its future, it becomes clear that the UAA has played - and will continue to play - a pivotal role in shaping urological care, education, and research throughout Asia. Reflecting on the path we’ve traveled together from 16 member associations and 1,000 individual members in 2014 to 28 member associations and over 4,500 individual members today - I see more than growth. I see unity, commitment, and a shared belief in something bigger than ourselves. A defining milestone was enrolling the Urological Society of Australia and New Zealand into the UAA, further enriching our diversity and strengthening our position as a truly Asia-Pacific organization. The UAA proudly supports several journals, including the International Journal of Urology, the Indian Journal of Urology, Asian Urology, which continue to shape the academic discourse. The Asian Urological Resident Course (AURC) started in 2014, in collaboration with the American Urological Association, has become a cornerstone in nurturing clinical excellence among young urologists. The Young Leadership Forum, since 2012, developed in partnership with the European Urological Association, has fostered cross-continental mentorship and exchange. These initiatives symbolize our commitment to creating a future shared across borders. We have faced challenges under the impact of COVID-19, but conquered it with resilience and shared purpose. As healthcare needs evolve and patient expectations rise, the UAA aims to: 1. Promote regional research 2. Enhance training and education 3. Strengthen partnerships 4. Champion equity in healthcare.Complex Robotic Assisted Surgery for Urinary Fistula RepairRobotic-assisted (da Vinci) surgery is increasingly used for repair of urinary fistulas, including vesicovaginal, ureterovaginal, and enterovesical fistula. It offers a minimally invasive alternative to open surgery. A case report described using the da Vinci X system to fix a vesicovaginal fistula (VVF) post-hysterectomy in 105 min with no complications, a 2 day hospital stay, and excellent patient reported quality-of-life at 12 months. A literature review including 30 cases showed robotic repair of VVF reduced blood loss and shortened hospital stays by 2 days compared to open repair. A review found that robotic repair of complex urinary fistulas is technically feasible in expert hands, with good early outcomes and less morbidity than open techniques.
This presentation illustrated the key operative procedures, inlcuding ureteral catheter placement to identify the ureteral tract, anchoring stitches on opened urinary bladder wall, robotic excision of the fistula tract, layered closure of bladder wall and adjacent organ (vagina or colon), with or without Interposition of tissue flaps (e.g. omentum or peritoneal flaps) to reinforce repair. The robot provides precise and secure ileal isolation with ICG technique for the ileal isolation, and and intracorporeal anastomosis to ureter and urinary bladder are safe. Intracorporeal bowel re-anastomosis and accessibility of the da Vinci platform is becoming more popular. The isolated ileal technique provides good urinary reconstruction (e.g., Neobladder, Augmentation Cystoplasty Ileal conduit (Bricker’s procedure), Orthotopic neobladder (Studer, Hautmann, etc.) The Role of the robot to harvestest, detubularize, and fold ileum to form bladder substitute. Suture to urethra and ureters. It is often performed entirely intracorporeally with the da Vinci Xi system.

Congratulations to both ARUS and PRUS!Aquablation Revolutionizing BPH Treatment: A New Era of Minimally Invasive Therapy-Tungs' Taichung Metroharbor Hospital ExperienceIntroduction
Aquablation is a waterjet ablation therapy for benign prostatic hyperplasia (BPH) that has gained significant attention. While its efficacy, durability, and safety have been established across various prostate sizes (30–150 mL), local data on its efficacy, safety, and learning curve in Taiwan remain limited. Our team have been performed 85 cases between March 2024 and July 2025. This lecture presents the learning curve observed in the first 50 patients who underwent Aquablation for BPH, highlighting its role in revolutionizing BPH treatment.
Materials and Methods
We conducted a retrospective review of 50 consecutive patients who underwent Aquablation between March 2024 and February 2025, dividing them into two groups: Group I (first 25 cases) and Group II (subsequent 25 cases). Assessments included IPSS, QoL, uroflowmetry parameters (voiding volume, Qmax, Qmean, PVR), operative time, hemoglobin drop, Clavien-Dindo grade ≥2 complications, hospital stay, and urethral catheter duration.
Results
Patients in Group II were younger and had smaller prostates. Aquablation was successfully performed in all cases. IPSS, QoL, voiding volume, Qmax, and Qmean improved significantly and were sustained for three months, while PVR improved only in Group I. Operative time was significantly shorter in Group II, and hemoglobin drop was greater in Group I. Complication rates, hospital stay, and catheter duration were similar between groups.
Conclusions
Aquablation provided significant and immediate improvements in voiding parameters and symptoms, with sustained PVR benefits in larger prostates. Surgeon proficiency improved after 25 cases. Overall, Aquablation proved safe and effective, even in an unselected patient population. Aquablation represents a promising advancement that could transform the therapeutic landscape for BPH—particularly if costs are reduced.Experience of 100 Consecutive Hugo Robotic Radical ProstatectomiesIntroduction and background:
Dr. Ou’ surgical team of Tungs’ Taichung MetroHarbor Hospital performed the first Hugo robotic radical prostatectomy on May 9, 2023. In 2023, we published the results of the first series of 12 Hugo robotic radical prostatectomies performed. In 2024, we published a comparison of 30 Hugo robotic radical prostatectomies and 30 Da Vinci robotic radical prostatectomies. Professor Ou is the Hugo robotic arm instructor recognized by Medtronic. Many Southeast Asian doctors come to this Hospital to observe the surgery and learn.
Material and Methods:
We prospectively collected data for retrospective analysis and statistics from May 9, 2023 to April 30, 2025, performing 100 consecutive Hugo robotic radical prostatectomies. We compared the surgical results of 1-50 cases (group 1) and 51-100 cases (group 2). The data analyzed included basic information, age, risk of anesthesia, BMI , prostate-specific antigen, clinical stage, and Gleason score grade. The two groups were compared in terms of surgical difficulty, receipt of neoadjuvant hormonal therapy, obesity, prostate volume >70 g, prostate protrusion more than 1 cm into the bladder neck, previous transurethral resection of prostate, history of abdominal surgery, extensive pelvic lymphadenectomy, salvage radical prostatectomy, and time from biopsy to radical prostatectomy less than 6 weeks. The two groups were compared in terms of robotic console time, blood loss, blood transfusion rate, and surgical complications. We compared the two groups in terms of postoperative pathological staging and grade, the proportion of tumor, and the proportion of urinary control at one month and three months.
Results:
The study showed that the age of patients in the second group was slightly higher, but the statistical p value was 0.058, which did not reach statistical difference. The second group of patients had significantly higher rates of stage III, stage IV, lymph node and bone oligometastasis, with a p value of 0.021. The rate of neoadjuvant hormonal therapy received by the second group was 16 percent, which was statistically significant compared with 2 percent of the first group (p = 0.021). The rates of other surgical difficulty factors were the same between the two groups. The average blood loss of patients in the second group was 156 CC, which was significantly less than the 208 CC in the first group. The operation time and surgical complications were comparable between the two groups. The cancer volume of the second group of patients was significantly reduced compared with that of the first group (3.30±2.93 versus 5.09±5.24, p value=0.049). The reason was that more patients in the second group received neoadjuvant hormonal therapy, which significantly reduced the cancer. Both groups of patients had very good urinary control after surgery.
Conclusion:
We conclude that Hugo robotic radical prostatectomy is an effective and feasible method with extremely low complications and good recovery of urinary control function after surgery. After the experience of the first 50 operations, the surgeon will choose patients with higher difficulty, especially those receiving neoadjuvant hormone therapy, to perform the operation.Total Solution of Maintenance of Urinary and Sex Function during Robotic Radical ProstatectomyBackground:
Robotic-assisted radical prostatectomy (RARP) has become a preferred surgical approach for localized prostate cancer due to its minimally invasive nature and precision. However, the preservation of urinary continence and sexual function remains a significant postoperative challenge. Traditional outcomes have focused heavily on oncological safety. Yet, contemporary perspectives emphasize a more holistic view—embodied in the concept of the “Pentafecta,” which includes continence, potency, negative surgical margins, biochemical recurrence-free survival, and absence of perioperative complications.
Objective:
This presentation introduces a comprehensive and integrative approach aimed at maximizing functional outcomes—particularly urinary continence and erectile function—through a modified pubovesical complex-sparing RARP under regional hypothermia, supplemented with real-time nerve imaging, neurovascular preservation strategies, and biological enhancement techniques.
Methods:
We present data and experience from Tungs’ Taichung MetroHarbor Hospital (TTMHH), including a series of 3780 robotic procedures performed between December 2005 and July 2025. Among these, 100 cases were completed using the Hugo™ RAS system and 21 with the da Vinci SP™ platform. Our modified technique builds upon Dr. Richard Gaston’s pubovesical complex-sparing method, with the addition of localized hypothermia (24°C), near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG), and application of dehydrated human amnion/chorion membrane (dHACM). In selected cases, nerve grafting with Axogen® technology was applied.
Results:
Initial results indicate a significantly improved early return of continence (95% by 16 weeks) and promising erectile function recovery, particularly in patients who received adjunctive therapies such as phosphodiesterase inhibitors or vacuum erection devices. The precision afforded by robotic technology enabled preservation of
prostate capsular arteries and accessory pudendal arteries. Localized hypothermia contributed to reduced tissue edema, minimized neural trauma, and improved nerve recovery. The use of ICG-NIRF allowed real-time identification of critical vascular landmarks, enhancing nerve-sparing accuracy. Preliminary analysis suggests our technique is both feasible and reproducible.
Conclusion:
The modified pubovesical complex-sparing RARP under hypothermia, augmented with vascular imaging and biologic materials, offers a promising paradigm for functional preservation in prostate cancer surgery. This total solution approach not only protects neurovascular integrity but also accelerates recovery of continence and potency.
Continued accumulation of clinical cases and controlled comparative studies are warranted to further validate the efficacy and long-term benefits of these techniques.
Significance:
This strategy reflects a patient-centered evolution in robotic prostate surgery, merging surgical innovation with anatomical preservation and technological augmentation. It represents an epic collaboration of surgical precision, team-based care, and thoughtful application of biomedical advances to improve quality of life outcomes in prostate
cancer patients.Total Solution of Maintenance of Urinary and Sex Function during Robotic Radical Prostatectomy

This strategy reflects a patient-centered evolution in robotic prostate surgery, merging surgical innovation with anatomical preservation and technological augmentation. It represents an epic collaboration of surgical precision, team-based care, and thoughtful application of biomedical advances to improve quality of life outcomes in prostate

Enhancing Robotic Surgery with AI and Imaging Navigation: Bridging Precision and EfficiencyBackground: Robotic surgery faces persistent challenges in real-time anatomical navigation during complex procedures like partial nephrectomy (PN), where millimeter-scale precision impacts oncological and functional outcomes.
Objective: This review explores the integration of artificial intelligence (AI) and augmented reality (AR)-based holographic imaging to overcome these limitations, synergistically advancing surgical precision and operational efficiency.
Design, setting and participants: Holographic imaging, an AR technique reconstructed from CT/MRI via surface rendering, provides detailed 3D anatomical models for preoperative planning, patient counseling, surgical training, and intraoperative navigation. These models enable precise tumor localization, super-selective vascular clamping, and parenchymal preservation, in particular the PN.
Results: Clinical outcomes demonstrate significant improvements. AI-automated modeling cuts 3D model reconstruction time while improving segmentation accuracy. AI enhanced holographic imaging in patient consultation, education and training, surgical planning, and surgical navigation have demonstrated value. Holographic imaging navigation overlays virtual models onto endoscopic views, reducing collecting system injury and increasing enucleation rates for endophytic tumors. AI-based holographic imaging visualization alters surgical strategy for complex cases, reducing conversion from partial to radical nephrectomy. Challenges persist in tracking robustness due to intraoperative organ deformation. Future directions include multimodal Integration: Combining holographic imaging and PET CT to define the metastatic lymph nodes, enabling personalized complete resection; Full-Cycle Coverage: Extending from preoperative assessment to postoperative recovery (e.g., recurrence prediction, customized rehabilitation plans); Telesurgery Empowerment: 5G + holographic imaging to support telesurgical guidance, promoting the decentralization of medical resources.
Conclusions: AI-powered holographic imaging navigation bridges critical gaps in robotic surgery by transforming static anatomical data into dynamic, real-time guidance. This synergy enhances precision in tumor resection and vascular management while streamlining workflows—ultimately improving patient outcomes through reduced ischemia, fewer complications, and greater nephron preservation, enhancing survival and quality of life for cancer patients. Real-time navigation integrating “anatomy-function-metabolism”, advancing MIS from “precision resection” to “personalized treatment” and "functional preservation”.

From Console to Cloud: The Evolution of Robotic Telesurgery in Urology – Innovations, Trials, and Ethical FrontiersTelesurgery is an emerging branch of surgery that utilizes telecommunication technology and surgical robots to perform operations. It breaks the spatial constraints on the conduct of surgical procedures and represents a systematic innovation brought about by the intersection of new technologies and concepts such as robotic surgery, telecommunication, and artificial intelligence. It holds promise as a potential solution to the uneven distribution of medical resources. Currently, China's research in telesurgery has reached the forefront of the international stage. Building a high-quality disciplinary development ecosystem and a regional collaborative system for remote surgery will be the inevitable path to maintaining a leading position. Providing national-level project support for telesurgery, establishing a national-level joint innovation group, creating a regional medical consortium for remote surgery, and formulating legal norms and treatment guidelines will pave the way for the sustainable development of telesurgery in China. It is believed that with the strong support of the state, Chinese surgeons will seize the opportunity, lead the new wave of surgical development, integrate new telesurgery technologies into the national universal healthcare system, and benefit a large number of patients.

Open Surgery Training: Is It Necessary in the Era of Robotics?Open surgery training in the era of robotics may or may not be a training environment that urology has control of, given worldwide access to robotic or at least laparoscopic techniques and strong patient preference. There may be some applications where a given experienced urologist can prefer open over minimally invasive surgery (MIS), such as radical cystectomy, or indications possibly outside of MIS feasibility such as large renal tumors with caval thrombus. Specific to training and expertise, there are 3 principle features of surgical skills desired: 1) knowing ideal exposure, 2) recognition of surgical planes, and 3) knowing anatomy before it can be seen. Although some trainees may only see MIS for certain indications, open surgery may expedite the process. There are no human studies identified on the topic, but a skills lab study was instructive (Farah, J Surgical Education 2023) showing that interns with open and MIS training performed higher comparing pre-intern to post intern bootcamp skills. The benefits of a solid training pathway including open experience are to move trainees towards the faster-to-progress part of the learning curve such that the attending can offer a safe training environment while moving the case along efficiently.The Future of Surgical Skills Evaluation: What Is on Your Wish List?Surgical skills training vary significantly by region with some systems putting trainees on a timed set of years, while others apprentice trainees until meeting a threshold for skills. Early training assessments were basic timed events with qualitative scores (subject to strong attending selection for success). Trainees should experience and/or study the key pitfalls to avoid and performance goals. Surgical simulation can be highly useful, but tend to improve only certain skills and not full case needs. Updated simulation moves from digital to hands on surgical models and may move the needle towards human experience. Training can be augmented with descriptors of surgical gestures and measuring which ones are most effective. The experience for the trainee is often depicted as an "autonomy gap" whereby the training desires to have case control, possibly before they are ready. Progression can be measured by descriptors of performance from assistance through full performance without coaching. The next frontier will be artificial intelligence guided measurement where specific performances can be characterized and diagnosed for success. My ultimate wishlist would be for methods to correlate skills to outcomes, optimized curricula, and a specific pathway to correct underperformance.Tips and Tricks in Challenging Cases of Robotic Radical ProstatectomyThere are many specific challenges with robotic radical prostatectomy (RARP) that can be described and illustrated--the most 5 common are 1) difficulty access, 2) obesity, 3) pubic arch interference, 4) anatomic challenges, and 5) reconstruction challenges. In this video sample, we demonstrate 2 challenges: obesity requiring a pelvic lymph node dissection and significant pelvic de-fatting to identify the proper surgical landmarks. Next a massive sized prostate that has had a partial transurethral resection--together presenting challenges with landmarks, a difficult bladder neck to diagnose, and final reconstruction challenges.

Surgical Robot-System hinotori in Urological Surgery: Clinical Applications and Future PotentialThe hinotori system was developed by Medicaroid, the partnership between Kawasaki, a leader in the industrial robots, and Sysmex, with its abundant expertise and networks in advanced medicine, released the first made-in-Japan RAS in 2020. The hinotori has been designed to reduce interference between arms and the surgeon at bedside. Equipped with four 8-axis robotic arms, providing smooth, highly articulated movements that mimic the human hand. In addition, docking-free design allows for a wide operative field around trocars, ensuring smooth workflows for surgeons and assistants. As a made-in-Japan system, it offers high adaptability to local clinical needs and faster implementation of user feedback.
Since the first launch, more 90 systems have been installed for the clinical use, not only inside Japan but foreign countries such as Singapore and Malaysia. The first one was performed in December 2020 on prostatectomy. Since then, more than 100,000 cases performed, including urology GI surgery, gynecology and thoracic fields. In urological surgery, robot-assisted surgery has been widely and promptly accepted as a standard approach for the majority of major surgeries, including robot-assisted radical prostatectomy (RARP), partial nephrectomy (RAPN), radical nephrectomy (RARN), radical nephroureterectomy (RANU), and radical cystectomy (RARC), and has generally shown findings superior to those of conventional open and laparoscopic surgeries
In conclusion, hinotori is a cutting-edge Japanese surgical robot already in use at many medical institutions. With strong performance across various surgical specialties and growing insurance coverage, it is expected to benefit even more patients as its technology continues to evolve and its global presence expands.Comparison of Various Current Surgical Robotic Systems - Nuances, Advantages, & DrawbacksIn the field of urology, robotic surgery has gained rapid and wide acceptance as a standard surgical care in the majority of surgeries over the last decade. To date, the da Vinci surgical system has been the dominant platform in robotic surgery; however, several newly developed robotic systems have recently been introduced in routine clinical practice. We, Fujita, installed the four different kinds of robotic platform for clinical usage such as, daVinci Xi, SP, hinotori and Hugo. In this study, we want to analyze the perioperative outcomes of robotic radical prostatectomy (RARP) and characterize the differences between four platforms.
hinotori : The hinotori system was developed by Medicaroid, the partnership between Kawasaki, a leader in the industrial robots, and Sysmex, with its abundant expertise and networks in advanced medicine, released the first made-in-Japan RAS in 2020. The hinotori has a compact operation arm with eight axes of motion, one more than the DaVinci, leading to reduce interference between arms and the surgeon at bedside.
DaVinci SP : The characteristic of the SP system can operate one 3D flexible camera and three forceps through a single port, and various surgical access is possible without the external interference of the arms. The various complicated procedures have been feasible such as NOTES or transoral surgery through the narrow space without the large wound, and retroperitoneal approach like the prostatectomy and partial nephrectomy. SP system is expected to contribute to develop the high quality surgery with minimal invasiveness.
Hugo : Hugo system (Medtronic) consists of an open-site console with two arm-controllers that are operated with a grip similar to a pistol. It also has a footswitch that controls the camera, energy source, and reserve arm. The system includes four separate arm carts, each with six joints to increase the range of motion. Additionally, it uses specific 3D glasses for head tracking technology.
Despite a small case series, there seemed to need learning-curve to get familiar with systems in setting-up and surgical procedures in introductory-phase. However, all the surgical procedures were efficaciously and safely performed, resulting in the achievement of favorable perioperative outcomes surgically as well as oncologically.
In conclusion, these new robots will lead to competition and reduce the costs of RAS and will contribute to an increase in use. Robotic-assisted surgery will become more common than laparoscopic surgery especially in the field of urology.

It’s a great honor to witness the signing of this partnership between the Asian Robotic Urology Society (ARUS) and the Philippines Robotic Urology Society (PRUS).
This marks the beginning of a new chapter in regional collaboration—one that emphasizes shared training, joint research, and mutual support to advance robotic urology across Asia. PRUS brings energy, expertise, and vision to this partnership, and ARUS is proud to walk alongside you as we work toward higher standards and better outcomes for our patients. Let us move forward together—with unity, purpose, and innovation.
Congratulations to both ARUS and PRUS!Aquablation Revolutionizing BPH Treatment: A New Era of Minimally Invasive Therapy-Tungs' Taichung Metroharbor Hospital ExperienceIntroduction
Aquablation is a waterjet ablation therapy for benign prostatic hyperplasia (BPH) that has gained significant attention. While its efficacy, durability, and safety have been established across various prostate sizes (30–150 mL), local data on its efficacy, safety, and learning curve in Taiwan remain limited. Our team have been performed 85 cases between March 2024 and July 2025. This lecture presents the learning curve observed in the first 50 patients who underwent Aquablation for BPH, highlighting its role in revolutionizing BPH treatment.
Materials and Methods
We conducted a retrospective review of 50 consecutive patients who underwent Aquablation between March 2024 and February 2025, dividing them into two groups: Group I (first 25 cases) and Group II (subsequent 25 cases). Assessments included IPSS, QoL, uroflowmetry parameters (voiding volume, Qmax, Qmean, PVR), operative time, hemoglobin drop, Clavien-Dindo grade ≥2 complications, hospital stay, and urethral catheter duration.
Results
Patients in Group II were younger and had smaller prostates. Aquablation was successfully performed in all cases. IPSS, QoL, voiding volume, Qmax, and Qmean improved significantly and were sustained for three months, while PVR improved only in Group I. Operative time was significantly shorter in Group II, and hemoglobin drop was greater in Group I. Complication rates, hospital stay, and catheter duration were similar between groups.
Conclusions
Aquablation provided significant and immediate improvements in voiding parameters and symptoms, with sustained PVR benefits in larger prostates. Surgeon proficiency improved after 25 cases. Overall, Aquablation proved safe and effective, even in an unselected patient population. Aquablation represents a promising advancement that could transform the therapeutic landscape for BPH—particularly if costs are reduced.Experience of 100 Consecutive Hugo Robotic Radical ProstatectomiesIntroduction and background:
Dr. Ou’ surgical team of Tungs’ Taichung MetroHarbor Hospital performed the first Hugo robotic radical prostatectomy on May 9, 2023. In 2023, we published the results of the first series of 12 Hugo robotic radical prostatectomies performed. In 2024, we published a comparison of 30 Hugo robotic radical prostatectomies and 30 Da Vinci robotic radical prostatectomies. Professor Ou is the Hugo robotic arm instructor recognized by Medtronic. Many Southeast Asian doctors come to this Hospital to observe the surgery and learn.
Material and Methods:
We prospectively collected data for retrospective analysis and statistics from May 9, 2023 to April 30, 2025, performing 100 consecutive Hugo robotic radical prostatectomies. We compared the surgical results of 1-50 cases (group 1) and 51-100 cases (group 2). The data analyzed included basic information, age, risk of anesthesia, BMI , prostate-specific antigen, clinical stage, and Gleason score grade. The two groups were compared in terms of surgical difficulty, receipt of neoadjuvant hormonal therapy, obesity, prostate volume >70 g, prostate protrusion more than 1 cm into the bladder neck, previous transurethral resection of prostate, history of abdominal surgery, extensive pelvic lymphadenectomy, salvage radical prostatectomy, and time from biopsy to radical prostatectomy less than 6 weeks. The two groups were compared in terms of robotic console time, blood loss, blood transfusion rate, and surgical complications. We compared the two groups in terms of postoperative pathological staging and grade, the proportion of tumor, and the proportion of urinary control at one month and three months.
Results:
The study showed that the age of patients in the second group was slightly higher, but the statistical p value was 0.058, which did not reach statistical difference. The second group of patients had significantly higher rates of stage III, stage IV, lymph node and bone oligometastasis, with a p value of 0.021. The rate of neoadjuvant hormonal therapy received by the second group was 16 percent, which was statistically significant compared with 2 percent of the first group (p = 0.021). The rates of other surgical difficulty factors were the same between the two groups. The average blood loss of patients in the second group was 156 CC, which was significantly less than the 208 CC in the first group. The operation time and surgical complications were comparable between the two groups. The cancer volume of the second group of patients was significantly reduced compared with that of the first group (3.30±2.93 versus 5.09±5.24, p value=0.049). The reason was that more patients in the second group received neoadjuvant hormonal therapy, which significantly reduced the cancer. Both groups of patients had very good urinary control after surgery.
Conclusion:
We conclude that Hugo robotic radical prostatectomy is an effective and feasible method with extremely low complications and good recovery of urinary control function after surgery. After the experience of the first 50 operations, the surgeon will choose patients with higher difficulty, especially those receiving neoadjuvant hormone therapy, to perform the operation.Total Solution of Maintenance of Urinary and Sex Function during Robotic Radical ProstatectomyBackground:
Robotic-assisted radical prostatectomy (RARP) has become a preferred surgical approach for localized prostate cancer due to its minimally invasive nature and precision. However, the preservation of urinary continence and sexual function remains a significant postoperative challenge. Traditional outcomes have focused heavily on oncological safety. Yet, contemporary perspectives emphasize a more holistic view—embodied in the concept of the “Pentafecta,” which includes continence, potency, negative surgical margins, biochemical recurrence-free survival, and absence of perioperative complications.
Objective:
This presentation introduces a comprehensive and integrative approach aimed at maximizing functional outcomes—particularly urinary continence and erectile function—through a modified pubovesical complex-sparing RARP under regional hypothermia, supplemented with real-time nerve imaging, neurovascular preservation strategies, and biological enhancement techniques.
Methods:
We present data and experience from Tungs’ Taichung MetroHarbor Hospital (TTMHH), including a series of 3780 robotic procedures performed between December 2005 and July 2025. Among these, 100 cases were completed using the Hugo™ RAS system and 21 with the da Vinci SP™ platform. Our modified technique builds upon Dr. Richard Gaston’s pubovesical complex-sparing method, with the addition of localized hypothermia (24°C), near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG), and application of dehydrated human amnion/chorion membrane (dHACM). In selected cases, nerve grafting with Axogen® technology was applied.
Results:
Initial results indicate a significantly improved early return of continence (95% by 16 weeks) and promising erectile function recovery, particularly in patients who received adjunctive therapies such as phosphodiesterase inhibitors or vacuum erection devices. The precision afforded by robotic technology enabled preservation of
prostate capsular arteries and accessory pudendal arteries. Localized hypothermia contributed to reduced tissue edema, minimized neural trauma, and improved nerve recovery. The use of ICG-NIRF allowed real-time identification of critical vascular landmarks, enhancing nerve-sparing accuracy. Preliminary analysis suggests our technique is both feasible and reproducible.
Conclusion:
The modified pubovesical complex-sparing RARP under hypothermia, augmented with vascular imaging and biologic materials, offers a promising paradigm for functional preservation in prostate cancer surgery. This total solution approach not only protects neurovascular integrity but also accelerates recovery of continence and potency.
Continued accumulation of clinical cases and controlled comparative studies are warranted to further validate the efficacy and long-term benefits of these techniques.
Significance:
This strategy reflects a patient-centered evolution in robotic prostate surgery, merging surgical innovation with anatomical preservation and technological augmentation. It represents an epic collaboration of surgical precision, team-based care, and thoughtful application of biomedical advances to improve quality of life outcomes in prostate
cancer patients.Total Solution of Maintenance of Urinary and Sex Function during Robotic Radical Prostatectomy

Update on the Apa Neoadjuvant TrialIn patients with high-risk prostate cancer (PCa), neoadjuvant androgen deprivation therapy (ADT) is not an accepted standard of care. However, we hypothesize that neoadjuvant ADT may result in improved quality of life by down-staging prostate cancer and thereby, permitting a better quality of nerve sparing. has demonstrated benefit in surgical outcomes after radical prostatectomy (RP). To test this hypothesis, we conducted a prospective randomized trial evaluating the effect of neoadjuvant Apalutamide (Apa) +/- abiraterone acetate/prednisone (AAP) and a gonadotropin-releasing hormone (GnRH) agonist on nerve sparing during RP in men with high-risk PCa. Update on the Results of SIMCAP StudyApproximately 7% of new prostate cancer (PCa) patients in the US will be diagnosed with metastatic disease. The role of surgery in this population remains unclear. To investigate the therapeutic value of radical prostatectomy in men with de novo metastatic prostate cancer, we are conducting the phase 2.5 randomized clinical trial SIMCAP (NCT03456843).

Robotic Radical Prostatectomy: Trying to Fit the Right Surgery to the Right PatientDefinitive treatment for localized prostate cancer included radical prostatectomy and radiation. Successful criteria of radical prostatectomy have to meet oncology control, not persistent PSA after surgery without salvage therapy. MRI imaging stage and PSA density are predictors for short‐term BCR after prostatectomy. NCCN‐defined high‐risk patients with a high initial PSA 28 density, imaging stage (T3aN0M0 and T3bN0M0), and 29 pathologic stage (any N1) had a higher risk of BCR when 30 compared with other patients with undetectable PSA, while 31 those with pathologic stage (T3bN0M0 or any N1) displayed 32 a higher risk of postoperatively detectable PSA. These find‐ 33 ings may help urologists to identify patients for whom active 34 therapeutic protocols are necessary.

PSA Kinetics Following PADT in mHSPC. Is It a Real-World Tool for Predicting Oncologic Outcome?PSA Kinetics following Primary Androgen Deprivation Therapy
(PADT) in mHSPC. Is it a Real-world Tool for Prediction Oncologic Outcome?
Bannakij Lojanapiwat, M.D.
Professor of Urology, Chiang Mai University, Thailand.
Of recent guidelines, upfront primary androgen deprivation monotherapy or combination therapy (PADT) is recommended for the treatment of metastatic hormone sensitive prostate cancer (mHSPC). Limitation of real-world treatment such as culture difference, financial barrier, geographic access to treatment and high operation/ radiation risks associated with medical comorbidity led to underutilization of combination therapy as the standard guideline. Prognostic factors are important in clinical practice which can predict the clinical outcome that offer the pre-treatment counseling for patients to select the optimal treatment.
Prostate specific antigen (PSA) levels is one of the important key prognostic markers. PSA kinetics of nadir PSA level and time to nadir PSA following the treatment are the important role for progression to CRPC and oncologic outcome. Our study and the previous studies reported better oncologic outcome especially overall survival, cancer specific survival and time to developed CRPC in mHSPC patients received upfront PADT who decline PSA≥95% (deep responder), PSA nadir ≤ 0.2 ng/ml (low PSA nadir level), time to PSA nadir ≥ 6 month and PSA decline velocity <11 ng/ml/month.
PSA Kinetics following Primary Androgen Deprivation Therapy (PADT) is one of a real-world tool for prediction oncologic outcome in the treatment of mHSPC.

Current Status & Future Perspective of Surgical Navigation in Robotic SurgeryRobot-assisted partial nephrectomy (RAPN) is a standard treatment for small renal cancer, however, the number of reports on the development of the image supported system and its effectiveness is small. The key point in the procedure of RAPN is to reliably identify renal artery in a space with few landmarks and to resect a tumor. To performe RAPN safely and reliably, we have already developed a surgical navigation specialized for RAPN, and published its usefulness in daVinci surgical systems. In this lecture, I would like to talk our recent projects updating our current navigation system. The first project focuses on 3D navigation using real-time forceps tracking. The second project is to develop an AI-based autonomous registration method for surgical navigation in RAPN. I hope that these 2 projects will further enhance the usefulness of our navigation system in RAPN.

Transurethral En Bloc Resection of Bladder Tumor: Where Are We Now?There is increasing evidence that transurethral en bloc resection of bladder tumour (ERBT) could lead to better peri-operative and oncological outcomes in patients with non-muscle-invasive bladder cancer. Modified approaches of ERBT have also been proposed to expand its indications for larger bladder tumours. The quality of resection is also the key for bladder-sparing treatment for muscle-invasive bladder cancer. We foresee an exciting journey ahead for ERBT, and as a urologist, we must embrace this novel technique for the best interest of our bladder cancer patients. To Publish or not to Publish? Navigating the path to academia in urologyDoing good science is the basis for technological advancement in healthcare. However, pursuing a path to academic in urology is often tough, stressful and frustrating. In this talk, I will share with you what I have learnt throughout my 15 years of research work. I will let you know what's the best and fastest way to become a globally renowned and successful researcher. Most importantly, I will explain what it takes to develop a great team and create a positive impact in people's lives. Believe in yourself!

Laser prostatectomy has also been used widely especially in patients who are on anticoagulants. However, both TURP and laser prostatectomy are associated with several problems including the need of spinal / general anaesthesia and the risk of male sexual dysfunction. In the past decade, we have witnessed the introduction of multiple new technologies including Rezum, Urolift, iTind and Aquablation. in this SIU lecture, we will discuss about the technical details, as well as the pros and cons of every new technology. We will also invite you to be our jury and decide whether TURP and laser prostatectomy will be replaced in the future. Novel Intravesical Therapeutics in the Evolving Landscape of NMIBCNon-muscle-invasive bladder cancer (NMIBC) is well known to be a difficult disease to manage, with a 1-year recurrence rate of up to 61% and 5-year recurrence rate of 78%. Despite the use of intravesical BCG therapy, NMIBC patients may still experience recurrence and develop what we call BCG-unresponsive NMIBC. Conventionally, we offer upfront radical cystectomy for patients with BCG-unresponsive NMIBC, however, this is an ultra-major surgery with significant risk of complications and could also lead to significant deterioration in quality of life in the long run. We are in urgent need for novel therapies to manage this difficult condition. In this lecture, we will discuss the evidence on the different novel intravesical therapies in treating BCG-unresponsive NMIBC.

Troubleshooting in Endoscopic Stone Surgery: How to Handle Unexpected Challenges in RIRS and ECIRSProstate Cancer Nomograms and Their Application in Asian MenNomograms help to predict outcomes in individual patients rather than whole populations and are an important part of evaluation and treatment decision making. Various nomograms have been developed in malignancies to predict and prognosticate clinical outcomes such as severity of disease, overall survival, and recurrence-free survival. In prostate cancer, nomograms were developed for determining need for biopsy, disease course, need for adjuvant therapy, and outcomes.
Most of these predictive nomograms were based on Caucasian populations. Prostate cancer is significantly affected by race, and Asian men have a significantly different racial and genetic susceptibility compared to Caucasians, raising the concern about the generalizability of these nomograms.
There are very few studies that have evaluated the applicability and validity of the existing nomograms in in Asian men. Most have found significant differences in the performance in this population. Thus, relying on such nomograms for treating Asian men may not be appropriate and collaborative efforts are required within Asian countries to develop locally relevant nomograms.What Is Critical Appraisal?Critical appraisal is the process of systematically evaluating research studies to assess their validity, relevance, and trustworthiness. The goal is to determine whether a study’s results are credible and useful for clinical decision-making, research, or policy. This has become increasingly important as there has been a massive increase in the number of scientific journals and not all published research is of equal quality. Critical appraisal helps healthcare professionals avoid being misled by poor-quality studies, make evidence-based decisions and improve patient outcomes.
The key purposes are to assess validity of the study and its results and determine applicability to the specific population. It involves assessing the study design, methodological quality, completeness of reporting, potential sources of bias and potential for misconduct.
There are number of reporting guidelines that can be used for performing critical appraisal. Additionally, being aware of essential reporting standards and common problems with studies can help readers make informed decisions.Scientific Misconduct and PitfallsNo abstractExample of the “Ideal” AbstractNo Abstract

Step-by-Step: Intra-Corporeal Orthotopic Bladder CreationIntra-corporeal orthotopic neobladder creation is a technically demanding yet feasible procedure performed following robotic radical cystectomy. Using a 40–50 cm segment of ileum, the bowel is isolated, detubularized along the antimesenteric border, and configured into a low-pressure reservoir. Urethro-ileal anastomosis is carefully performed to ensure a tension-free, watertight connection, followed by uretero-ileal anastomoses using the Wallace technique with ureteral stent placement. The intra-corporeal approach minimizes bowel handling, facilitates faster recovery, and preserves pelvic anatomy, offering potential advantages in continence and postoperative outcomes when performed by experienced robotic surgeons.

Congratulations to both ARUS and PRUS!Aquablation Revolutionizing BPH Treatment: A New Era of Minimally Invasive Therapy-Tungs' Taichung Metroharbor Hospital ExperienceIntroduction
Aquablation is a waterjet ablation therapy for benign prostatic hyperplasia (BPH) that has gained significant attention. While its efficacy, durability, and safety have been established across various prostate sizes (30–150 mL), local data on its efficacy, safety, and learning curve in Taiwan remain limited. Our team have been performed 85 cases between March 2024 and July 2025. This lecture presents the learning curve observed in the first 50 patients who underwent Aquablation for BPH, highlighting its role in revolutionizing BPH treatment.
Materials and Methods
We conducted a retrospective review of 50 consecutive patients who underwent Aquablation between March 2024 and February 2025, dividing them into two groups: Group I (first 25 cases) and Group II (subsequent 25 cases). Assessments included IPSS, QoL, uroflowmetry parameters (voiding volume, Qmax, Qmean, PVR), operative time, hemoglobin drop, Clavien-Dindo grade ≥2 complications, hospital stay, and urethral catheter duration.
Results
Patients in Group II were younger and had smaller prostates. Aquablation was successfully performed in all cases. IPSS, QoL, voiding volume, Qmax, and Qmean improved significantly and were sustained for three months, while PVR improved only in Group I. Operative time was significantly shorter in Group II, and hemoglobin drop was greater in Group I. Complication rates, hospital stay, and catheter duration were similar between groups.
Conclusions
Aquablation provided significant and immediate improvements in voiding parameters and symptoms, with sustained PVR benefits in larger prostates. Surgeon proficiency improved after 25 cases. Overall, Aquablation proved safe and effective, even in an unselected patient population. Aquablation represents a promising advancement that could transform the therapeutic landscape for BPH—particularly if costs are reduced.Experience of 100 Consecutive Hugo Robotic Radical ProstatectomiesIntroduction and background:
Dr. Ou’ surgical team of Tungs’ Taichung MetroHarbor Hospital performed the first Hugo robotic radical prostatectomy on May 9, 2023. In 2023, we published the results of the first series of 12 Hugo robotic radical prostatectomies performed. In 2024, we published a comparison of 30 Hugo robotic radical prostatectomies and 30 Da Vinci robotic radical prostatectomies. Professor Ou is the Hugo robotic arm instructor recognized by Medtronic. Many Southeast Asian doctors come to this Hospital to observe the surgery and learn.
Material and Methods:
We prospectively collected data for retrospective analysis and statistics from May 9, 2023 to April 30, 2025, performing 100 consecutive Hugo robotic radical prostatectomies. We compared the surgical results of 1-50 cases (group 1) and 51-100 cases (group 2). The data analyzed included basic information, age, risk of anesthesia, BMI , prostate-specific antigen, clinical stage, and Gleason score grade. The two groups were compared in terms of surgical difficulty, receipt of neoadjuvant hormonal therapy, obesity, prostate volume >70 g, prostate protrusion more than 1 cm into the bladder neck, previous transurethral resection of prostate, history of abdominal surgery, extensive pelvic lymphadenectomy, salvage radical prostatectomy, and time from biopsy to radical prostatectomy less than 6 weeks. The two groups were compared in terms of robotic console time, blood loss, blood transfusion rate, and surgical complications. We compared the two groups in terms of postoperative pathological staging and grade, the proportion of tumor, and the proportion of urinary control at one month and three months.
Results:
The study showed that the age of patients in the second group was slightly higher, but the statistical p value was 0.058, which did not reach statistical difference. The second group of patients had significantly higher rates of stage III, stage IV, lymph node and bone oligometastasis, with a p value of 0.021. The rate of neoadjuvant hormonal therapy received by the second group was 16 percent, which was statistically significant compared with 2 percent of the first group (p = 0.021). The rates of other surgical difficulty factors were the same between the two groups. The average blood loss of patients in the second group was 156 CC, which was significantly less than the 208 CC in the first group. The operation time and surgical complications were comparable between the two groups. The cancer volume of the second group of patients was significantly reduced compared with that of the first group (3.30±2.93 versus 5.09±5.24, p value=0.049). The reason was that more patients in the second group received neoadjuvant hormonal therapy, which significantly reduced the cancer. Both groups of patients had very good urinary control after surgery.
Conclusion:
We conclude that Hugo robotic radical prostatectomy is an effective and feasible method with extremely low complications and good recovery of urinary control function after surgery. After the experience of the first 50 operations, the surgeon will choose patients with higher difficulty, especially those receiving neoadjuvant hormone therapy, to perform the operation.Total Solution of Maintenance of Urinary and Sex Function during Robotic Radical ProstatectomyBackground:
Robotic-assisted radical prostatectomy (RARP) has become a preferred surgical approach for localized prostate cancer due to its minimally invasive nature and precision. However, the preservation of urinary continence and sexual function remains a significant postoperative challenge. Traditional outcomes have focused heavily on oncological safety. Yet, contemporary perspectives emphasize a more holistic view—embodied in the concept of the “Pentafecta,” which includes continence, potency, negative surgical margins, biochemical recurrence-free survival, and absence of perioperative complications.
Objective:
This presentation introduces a comprehensive and integrative approach aimed at maximizing functional outcomes—particularly urinary continence and erectile function—through a modified pubovesical complex-sparing RARP under regional hypothermia, supplemented with real-time nerve imaging, neurovascular preservation strategies, and biological enhancement techniques.
Methods:
We present data and experience from Tungs’ Taichung MetroHarbor Hospital (TTMHH), including a series of 3780 robotic procedures performed between December 2005 and July 2025. Among these, 100 cases were completed using the Hugo™ RAS system and 21 with the da Vinci SP™ platform. Our modified technique builds upon Dr. Richard Gaston’s pubovesical complex-sparing method, with the addition of localized hypothermia (24°C), near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG), and application of dehydrated human amnion/chorion membrane (dHACM). In selected cases, nerve grafting with Axogen® technology was applied.
Results:
Initial results indicate a significantly improved early return of continence (95% by 16 weeks) and promising erectile function recovery, particularly in patients who received adjunctive therapies such as phosphodiesterase inhibitors or vacuum erection devices. The precision afforded by robotic technology enabled preservation of
prostate capsular arteries and accessory pudendal arteries. Localized hypothermia contributed to reduced tissue edema, minimized neural trauma, and improved nerve recovery. The use of ICG-NIRF allowed real-time identification of critical vascular landmarks, enhancing nerve-sparing accuracy. Preliminary analysis suggests our technique is both feasible and reproducible.
Conclusion:
The modified pubovesical complex-sparing RARP under hypothermia, augmented with vascular imaging and biologic materials, offers a promising paradigm for functional preservation in prostate cancer surgery. This total solution approach not only protects neurovascular integrity but also accelerates recovery of continence and potency.
Continued accumulation of clinical cases and controlled comparative studies are warranted to further validate the efficacy and long-term benefits of these techniques.
Significance:
This strategy reflects a patient-centered evolution in robotic prostate surgery, merging surgical innovation with anatomical preservation and technological augmentation. It represents an epic collaboration of surgical precision, team-based care, and thoughtful application of biomedical advances to improve quality of life outcomes in prostate
cancer patients.Total Solution of Maintenance of Urinary and Sex Function during Robotic Radical Prostatectomy

Enhancing Robotic Surgery with AI and Imaging Navigation: Bridging Precision and EfficiencyBackground: Robotic surgery faces persistent challenges in real-time anatomical navigation during complex procedures like partial nephrectomy (PN), where millimeter-scale precision impacts oncological and functional outcomes.
Objective: This review explores the integration of artificial intelligence (AI) and augmented reality (AR)-based holographic imaging to overcome these limitations, synergistically advancing surgical precision and operational efficiency.
Design, setting and participants: Holographic imaging, an AR technique reconstructed from CT/MRI via surface rendering, provides detailed 3D anatomical models for preoperative planning, patient counseling, surgical training, and intraoperative navigation. These models enable precise tumor localization, super-selective vascular clamping, and parenchymal preservation, in particular the PN.
Results: Clinical outcomes demonstrate significant improvements. AI-automated modeling cuts 3D model reconstruction time while improving segmentation accuracy. AI enhanced holographic imaging in patient consultation, education and training, surgical planning, and surgical navigation have demonstrated value. Holographic imaging navigation overlays virtual models onto endoscopic views, reducing collecting system injury and increasing enucleation rates for endophytic tumors. AI-based holographic imaging visualization alters surgical strategy for complex cases, reducing conversion from partial to radical nephrectomy. Challenges persist in tracking robustness due to intraoperative organ deformation. Future directions include multimodal Integration: Combining holographic imaging and PET CT to define the metastatic lymph nodes, enabling personalized complete resection; Full-Cycle Coverage: Extending from preoperative assessment to postoperative recovery (e.g., recurrence prediction, customized rehabilitation plans); Telesurgery Empowerment: 5G + holographic imaging to support telesurgical guidance, promoting the decentralization of medical resources.
Conclusions: AI-powered holographic imaging navigation bridges critical gaps in robotic surgery by transforming static anatomical data into dynamic, real-time guidance. This synergy enhances precision in tumor resection and vascular management while streamlining workflows—ultimately improving patient outcomes through reduced ischemia, fewer complications, and greater nephron preservation, enhancing survival and quality of life for cancer patients. Real-time navigation integrating “anatomy-function-metabolism”, advancing MIS from “precision resection” to “personalized treatment” and "functional preservation”.

Surgical Robot-System hinotori in Urological Surgery: Clinical Applications and Future PotentialThe hinotori system was developed by Medicaroid, the partnership between Kawasaki, a leader in the industrial robots, and Sysmex, with its abundant expertise and networks in advanced medicine, released the first made-in-Japan RAS in 2020. The hinotori has been designed to reduce interference between arms and the surgeon at bedside. Equipped with four 8-axis robotic arms, providing smooth, highly articulated movements that mimic the human hand. In addition, docking-free design allows for a wide operative field around trocars, ensuring smooth workflows for surgeons and assistants. As a made-in-Japan system, it offers high adaptability to local clinical needs and faster implementation of user feedback.
Since the first launch, more 90 systems have been installed for the clinical use, not only inside Japan but foreign countries such as Singapore and Malaysia. The first one was performed in December 2020 on prostatectomy. Since then, more than 100,000 cases performed, including urology GI surgery, gynecology and thoracic fields. In urological surgery, robot-assisted surgery has been widely and promptly accepted as a standard approach for the majority of major surgeries, including robot-assisted radical prostatectomy (RARP), partial nephrectomy (RAPN), radical nephrectomy (RARN), radical nephroureterectomy (RANU), and radical cystectomy (RARC), and has generally shown findings superior to those of conventional open and laparoscopic surgeries
In conclusion, hinotori is a cutting-edge Japanese surgical robot already in use at many medical institutions. With strong performance across various surgical specialties and growing insurance coverage, it is expected to benefit even more patients as its technology continues to evolve and its global presence expands.Comparison of Various Current Surgical Robotic Systems - Nuances, Advantages, & DrawbacksIn the field of urology, robotic surgery has gained rapid and wide acceptance as a standard surgical care in the majority of surgeries over the last decade. To date, the da Vinci surgical system has been the dominant platform in robotic surgery; however, several newly developed robotic systems have recently been introduced in routine clinical practice. We, Fujita, installed the four different kinds of robotic platform for clinical usage such as, daVinci Xi, SP, hinotori and Hugo. In this study, we want to analyze the perioperative outcomes of robotic radical prostatectomy (RARP) and characterize the differences between four platforms.
hinotori : The hinotori system was developed by Medicaroid, the partnership between Kawasaki, a leader in the industrial robots, and Sysmex, with its abundant expertise and networks in advanced medicine, released the first made-in-Japan RAS in 2020. The hinotori has a compact operation arm with eight axes of motion, one more than the DaVinci, leading to reduce interference between arms and the surgeon at bedside.
DaVinci SP : The characteristic of the SP system can operate one 3D flexible camera and three forceps through a single port, and various surgical access is possible without the external interference of the arms. The various complicated procedures have been feasible such as NOTES or transoral surgery through the narrow space without the large wound, and retroperitoneal approach like the prostatectomy and partial nephrectomy. SP system is expected to contribute to develop the high quality surgery with minimal invasiveness.
Hugo : Hugo system (Medtronic) consists of an open-site console with two arm-controllers that are operated with a grip similar to a pistol. It also has a footswitch that controls the camera, energy source, and reserve arm. The system includes four separate arm carts, each with six joints to increase the range of motion. Additionally, it uses specific 3D glasses for head tracking technology.
Despite a small case series, there seemed to need learning-curve to get familiar with systems in setting-up and surgical procedures in introductory-phase. However, all the surgical procedures were efficaciously and safely performed, resulting in the achievement of favorable perioperative outcomes surgically as well as oncologically.
In conclusion, these new robots will lead to competition and reduce the costs of RAS and will contribute to an increase in use. Robotic-assisted surgery will become more common than laparoscopic surgery especially in the field of urology.

Open Surgery Training: Is It Necessary in the Era of Robotics?Open surgery training in the era of robotics may or may not be a training environment that urology has control of, given worldwide access to robotic or at least laparoscopic techniques and strong patient preference. There may be some applications where a given experienced urologist can prefer open over minimally invasive surgery (MIS), such as radical cystectomy, or indications possibly outside of MIS feasibility such as large renal tumors with caval thrombus. Specific to training and expertise, there are 3 principle features of surgical skills desired: 1) knowing ideal exposure, 2) recognition of surgical planes, and 3) knowing anatomy before it can be seen. Although some trainees may only see MIS for certain indications, open surgery may expedite the process. There are no human studies identified on the topic, but a skills lab study was instructive (Farah, J Surgical Education 2023) showing that interns with open and MIS training performed higher comparing pre-intern to post intern bootcamp skills. The benefits of a solid training pathway including open experience are to move trainees towards the faster-to-progress part of the learning curve such that the attending can offer a safe training environment while moving the case along efficiently.The Future of Surgical Skills Evaluation: What Is on Your Wish List?Surgical skills training vary significantly by region with some systems putting trainees on a timed set of years, while others apprentice trainees until meeting a threshold for skills. Early training assessments were basic timed events with qualitative scores (subject to strong attending selection for success). Trainees should experience and/or study the key pitfalls to avoid and performance goals. Surgical simulation can be highly useful, but tend to improve only certain skills and not full case needs. Updated simulation moves from digital to hands on surgical models and may move the needle towards human experience. Training can be augmented with descriptors of surgical gestures and measuring which ones are most effective. The experience for the trainee is often depicted as an "autonomy gap" whereby the training desires to have case control, possibly before they are ready. Progression can be measured by descriptors of performance from assistance through full performance without coaching. The next frontier will be artificial intelligence guided measurement where specific performances can be characterized and diagnosed for success. My ultimate wishlist would be for methods to correlate skills to outcomes, optimized curricula, and a specific pathway to correct underperformance.Tips and Tricks in Challenging Cases of Robotic Radical ProstatectomyThere are many specific challenges with robotic radical prostatectomy (RARP) that can be described and illustrated--the most 5 common are 1) difficulty access, 2) obesity, 3) pubic arch interference, 4) anatomic challenges, and 5) reconstruction challenges. In this video sample, we demonstrate 2 challenges: obesity requiring a pelvic lymph node dissection and significant pelvic de-fatting to identify the proper surgical landmarks. Next a massive sized prostate that has had a partial transurethral resection--together presenting challenges with landmarks, a difficult bladder neck to diagnose, and final reconstruction challenges.

Hugo : Hugo system (Medtronic) consists of an open-site console with two arm-controllers that are operated with a grip similar to a pistol. It also has a footswitch that controls the camera, energy source, and reserve arm. The system includes four separate arm carts, each with six joints to increase the range of motion. Additionally, it uses specific 3D glasses for head tracking technology.
Despite a small case series, there seemed to need learning-curve to get familiar with systems in setting-up and surgical procedures in introductory-phase. However, all the surgical procedures were efficaciously and safely performed, resulting in the achievement of favorable perioperative outcomes surgically as well as oncologically.
In conclusion, these new robots will lead to competition and reduce the costs of RAS and will contribute to an increase in use. Robotic-assisted surgery will become more common than laparoscopic surgery especially in the field of urology.
