  • Ryoichi Shiroki Japan Moderator 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.

    John DavisUnited States Speaker 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.

Renal Cell Carcinoma
  • Siros JitpraphaiThailand Speaker RCC and IVC ThrombectomyRCC and IVC thrombus Siros Jitpraphai Division of Urology, Department of Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, THAILAND Abstract Renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombus represents a complex surgical challenge, with an incidence of venous involvement in 4-10% of cases. This case report demonstrates the successful surgical management of a 58-year-old female patient with a large left-sided renal mass and IVC thrombus. The patient presented with gross hematuria and was diagnosed with a 10 cm clear cell renal cell carcinoma (Fuhrman nuclear grade 3) extending into the renal vein and IVC. Recognizing the complexity of the case, a multidisciplinary approach was employed, involving urological and hepatobiliary surgical teams. The comprehensive treatment strategy included an open radical nephrectomy with IVC thrombectomy. The surgical technique was meticulously planned and executed, with several key considerations. Preoperative imaging was crucial in determining the exact level of thrombus, allowing for precise surgical planning. The procedure emphasized careful vascular control and en-bloc tumor removal, with intraoperative ultrasound used to ensure accurate thrombus localization. Surgical teams worked collaboratively to minimize potential complications and maximize surgical success. Operatively, the procedure was substantial, with an estimated blood loss of 900 mL and a total operative time of 5 hours. The patient required two days of postoperative intensive care and was discharged from the hospital seven days after the surgery. Pathological examination confirmed the diagnosis of clear cell renal cell carcinoma, with no lymph node metastasis detected and positive tumor thrombus. Importantly, surgical margins were found to be free of tumor. Follow-up evaluations have been encouraging, with no signs of tumor recurrence observed during regular intervals. This case illustrates the critical importance of a systematic surgical approach, precise technical execution, and comprehensive multidisciplinary management in successfully treating RCC with IVC thrombus. It provides valuable insights into the complex surgical management of this challenging condition, potentially offering guidance for similar cases in the future. Keyword: RCC (Renal Cell Carcinoma), IVC Thrombus, Thrombectomy, Surgical Technique, Multidisciplinary Management Highlight: RCC with IVC thrombus is a complex surgical challenge affecting 4-10% of cases. Successful management requires meticulous preoperative imaging, multidisciplinary team approach, and precise surgical technique. With careful planning and execution, 45-70% of patients can be cured through radical nephrectomy and IVC thrombectomy. Robotic Partial Nephrectomy in Complex and Difficult Tumor Location

Across clear-cell RCC (ccRCC), recurrent alterations include VHL, PBRM1, BAP1, and SETD2, mapping onto five dominant axes: hypoxia signaling (VHL–HIF), PI3K/AKT/mTOR, chromatin remodeling, cell-cycle control, and metabolic rewiring. These lesions variably interact—e.g., mTORC1 enhances HIF translation—creating therapeutic opportunities (VEGF tyrosine-kinase inhibitors, HIF-2α inhibition, mTOR blockade) and constraints (adaptive resistance via metabolic plasticity). While immune checkpoint inhibitors (ICIs) and ICI–TKI combinations have improved outcomes in metastatic RCC, robust predictive biomarkers remain elusive. Tumor mutational burden is typically low and noninformative; PD-L1 shows assay- and context-dependent utility; PBRM1 and BAP1 are more prognostic than predictive. Emerging signals include angiogenic versus T-effector/myeloid transcriptional signatures, sarcomatoid/rhabdoid histology as a surrogate of immune-inflamed state, and host factors such as HLA genotype and gut microbiome composition. Liquid-biopsy modalities (ctDNA and methylome profiling) and spatial/single-cell atlases reveal intratumoral heterogeneity, T-cell exclusion niches, and myeloid programs (e.g., TREM2⁺ macrophages) linked to recurrence or ICI benefit. Early data support metabolism-targeted strategies (e.g., glutaminase inhibition) and rational combinations co-targeting angiogenesis, hypoxia signaling, and immune checkpoints; however, toxicity management and resistance evolution require prospective, biomarker-integrated trials. A clinical schema that pairs baseline multi-omic and microenvironmental profiling with adaptive surveillance (serial liquid biopsies, functional imaging) can lead to dynamically select among ICI–ICI, ICI–TKI, targeted, and experimental regimens. Robotic Prostatectomy Using da Vinci SP System
  • Seong Il SeoKorea (Republic of) Speaker Comparison of Remal Function between Radiofrequency Ablation versus Robot Assisted Laparoscopic Patial Nephrectomy for Small Renal Mass in Elderly PatientsComparison of renal function between radiofrequency ablation versus robot assisted laparoscopic partial nephrectomy for small renal mass in elderly patients Jiwoong Yu, Seongil Seo Sungkyunkwan University, Samsung Medical Center The incidence of small renal masses (SRMs) in patients ≥75 years has increased up to 30-fold [J Urol 2014]. In this age group, treatment should balance cancer control and renal function preservation. Robot-assisted partial nephrectomy (RAPN) and radiofrequency ablation (RFA) are two main options. RAPN offers excellent cancer control but requires general anesthesia and ischemia, which may pose risks in older patients. RFA is less invasive, avoids vascular clamping, and is often preferred for high-risk patients, as supported by EAU and AUA guidelines. RFA generally preserves renal function better [Front Oncol 2022], though outcomes vary by technique. At our center, RFA under general anesthesia with wide safety margins may compromise parenchymal preservation. While both approaches show favorable cancer control, RFA has a slightly higher recurrence rate. Pantelidou et al. reported 6 recurrences in 63 RFA cases vs. 1 in 63 RAPN cases [Cardiovasc Intervent Radiol 2016], and Park et al. reported 2-year recurrence-free survival (RFS) of 95.2% in RFA vs. 100% in RAPN [Eur Radiol 2018]. NCCN guidelines note that RFA may require repeat treatment to match surgical outcomes. Our institutional matched analysis (63 RAPN vs. 63 RFA) showed RFS of 100% vs. 95.2% (p = 0.029), and immediate eGFR preservation of 91.7% vs. 86.8% [Eur Radiol 2018;28:2979–2985]. A subsequent analysis of older patients presented at AUA 2024 included 137 patients aged ≥75, the rate of ≥25% eGFR decline at one year was 28.6% for RFA vs. 2.0% for RAPN (HR 11.3, p = 0.002), with 4 recurrences in RFA and none in RAPN. In conclusion, both RFA and RAPN are viable options for elderly patients with small renal masses. RFA is less invasive but may carry a slightly higher risk of recurrence and, depending on institutional technique, some degree of renal function loss. Treatment should be individualized based on tumor anatomy, patient condition, and institutional expertise.

  • Allen W. ChiuTaiwan Speaker 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.

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?

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.
