Medical research is what allows doctors to explore unmet medical need and decide how to best treat patients. It is what makes the development of new diagnostic tools, new biomarkers, new medicines, and new procedures. Without medical research, we would not be able to creative new knowledge and decide if new treatments are better than our current treatments.
There are some Tips on what to do about what research is and how to get into it:
1. Ask a good question from your daily practice, what is unmet medical need?
2. Search the old literature of your research interests- what is known? What is unknown?
3. Find a new method to solve your question or an old method but applying to a new field.
4. Start from jointing a pre-planned research project, and join a research collaborative.
5. Try to be an independent researcher from a small project without funding support, retrospective study.
6. Try to get funding support from your institute, national grant, or industry.
As a young doctor, it’s important to look after yourself and maintain a healthy balance between daily practice and research work. There is a range of options for doctors interested in research, from smaller time commitments as a co-investigator to longer-term projects and experience as chief investigator. Research works are all optional activities, so do what you can but don’t overwhelm yourself. Road to Excellent Research

New Artificial Urinary SphinterStress urinary incontinence remains a major quality-of-life concern, particularly following pelvic surgery. Despite being the gold standard, the AMS 800 artificial urinary sphincter (AUS) presents significant limitations, including mechanical failure, urethral atrophy, and challenges for elderly or disabled patients. Recent innovations in AUS design now incorporate mechatronics, remote control, adaptive pressure systems, and miniaturized components aimed at improving usability, autonomy, and continence outcomes. This presentation reviews the current landscape of next-generation AUS, focusing on ARTUS, UroActive®, and other devices under clinical evaluation. We discuss preclinical and first-in-human data, regulatory pathways, patient-reported preferences, and remaining barriers such as infection risks and training requirements. Intelligent, connected AUS devices hold promise to transform continence care after decades of technological stagnation.Choosing between Laparoscopic Sacrocolpopexy and Lateral Suspension: Weighing the Pros and ConsPelvic organ prolapse (POP) is a common condition requiring surgical intervention to restore apical support. Among minimally invasive options, laparoscopic sacrocolpopexy (LSCP) remains the gold standard, while laparoscopic lateral suspension (LLS) is gaining renewed interest for its reduced invasiveness and simplified technique. This presentation compares LSCP and LLS across multiple dimensions: anatomical restoration, functional outcomes, complication profiles, patient selection, and surgical learning curves. LSCP offers robust long-term results and better posterior compartment support but carries increased operative complexity. LLS provides effective anterior/apical correction with fewer vascular risks and a shorter learning curve. Both techniques have comparable mesh exposure rates and subjective success. Individualized decision-making based on patient anatomy, comorbidities, and surgeon expertise remains key. Emerging technologies and robotic assistance may further refine these approaches in the future.Robotic Novel Artificial Urinary Sphincter ImplantationThis video shows a step by step robotic artificial urinary sphincter implantation in women using AMS800 and Artus devices.First robot-assisted implantation of ARTUS (Affluent Medical) electromechanical artificial urinary sphincter in a female cadaverIntroduction
Artificial urinary sphincters (AUS) are effective tools for the treatment of female stress urinary incontinence. Nonetheless, hydraulic sphincters present with some limitations: complex and time-consuming preparation, need for preserved manual dexterity and constant pressure exertion on the bladder neck. The ARTUS® Artificial Urinary Sphincter is a novel electro-mechanical device designed to overcome these limitations thanks to its rapid and straight-forward implantation, intuitive remotely controlled manipulation and continuously adjustable cuff pressure.
Materials and methods
The ARTUS® system is currently under pre-market investigation in men, in an interventional, prospective, single arm, multicentric, international study. A cadaver lab session was carried out in Decembre 2024 to test the technical feasibility of ARTUS® implantation in female patients. The procedure was performed by an expert surgeon with extensive experience in AUS implantation and robotic surgery.
Results
One female patient was successfully implanted during the session. The technique has been developed following the principles of the traditional robot-assisted AUS implantation: the patient is placed in gynecological 23° Trendelenburg position. The robot has a 4-arms configuration. The procedure starts with the dissection of the vesicovaginal plane, to approach the bladder neck posteriorly. The lateral surfaces of the bladder neck are developed on both sides. The anterior peritoneum is opened to gain access to the antero-lateral surfaces of the bladder. The separation of the bladder neck from the vagina is performed through dissection of the pre-vaginal fascia bilaterally. The cuff is introduced and it is passed through the antero-lateral peri-vesical spaces, sliding behind the bladder neck from the right side to the left side. The anterior peritoneum is opened to gain access to the anterior surface of the bladder neck. The cuff is closed anteriorly, passing the transmission line inside the hole at the distal part of the cuff. The tightening around the bladder neck is achieved by pulling the transmission cable through. An optimal adjustment of the cuff around the bladder neck is provided tightening the ARTUS cuff clamping notch. Then, a supra-pubic 4 cm skin incision is made to implant the control unit. The tip of the cuff is passed outside through the incision. A lodge is prepared incising along the external oblique muscle aponeurosis. The cuff is connected to the control unit and a test with the remote control is performed to verify the functioning of the system. Finally, the control unit is placed into the lodge, anchored with non-absorbable sutures to the aponeurosis.
Conclusions
Robot-assisted ARTUS® implantation is technically feasible in female patients. This straight-forward technique may reduce operative time. The device has the potential to reduce the pressure and facilitate manipulation in patients with impaired dexterity.

Robotic/Laparoscopic Sacrocolpopexy and Pelvic Floor ReconstructionAbdominal sacrocolpopexy has been the gold standard operation for POP. Currently, the trend is minimal-invasive surgeries such as laparoscopy(LSC) or robot-assisted laparoscopy(RASC) to promote recovery. However, surgeons hesitated to do it because of longer learning curve and complicated surgical procedures. How to simplify the above operations is the most important issue.
The use of robotic assisted surgery has grown since the advent of better wrist dexterity, a 3D view, and motion scaling, which has great advantages in performing sacrocolpopexy. But the efficacy of RASC and LSC is comparable as indicated in previous studies, and the only difference is less bleeding with the RASC.

Which Laser for RIRS: Thulium Fiber Laser Thulium Fiber Laser (TFL)is a type of fiber laser, distinct from Thulium laser used for prostate surgey. It’ a cutting-edge laser and rapidly gaining traction in urology The machine is compact, portable, quiet with air-cooling, and lower power consumption.It employs a thulium-doped silica fiber powered by diode lasers, emitting light at 1940 nm, matching water absorption peaks. This results in a high absorption coefficient and shallow penetration (~0.1 mm), enabling precise energy delivery and minimizing tissue damage.Compared to Holmium lasers, TFL operates at lower energies (down to 25mJ) and higher frequencies (up to 2000Hz) for delicate tissue ablation and fine stone dusting.
The most notable change is pulse modulationHo:YAG lasers has Spike-shaped pulses and indicate greater energy concentration, resulting in higher localized heating, uneven fragmentation, and increased retropulsion.TFL produces pulses with uniform energy distribution and lower peak power, resulting in consistent ablation with less retropulsion and fewer thermal spikes.Higher water absorption rapidly forms a vapor channel, enhancing ablation efficiency.
But, TFL is not as ideal in surgical scenarios. At settings of low pulse energy (0.2 J) and high frequency (100 Hz), it tends to cause troublesome char formation and spark generation, particularly when treating calcium phosphate stones. These phenomena, explosive combustion and carbonization can reduce ablation efficiency and increase the risk of thermal damage and fiber degradation. Optimizing TFL settings is very important for outcome and safety and ongoing evaluation. AI in Medical Imaging – Converting 2D Black & White to 3D and Applications in Mixed Reality (MR) used in RIRS Artificial Intelligence (AI) and Extended Reality (XR) are at the forefront of innovation in modern medicine. In endoscopic surgery, these technologies are increasingly being integrated to enhance procedural precision and intraoperative guidance.
One experimental application involves using AI to convert 2D CT scans into 3D visualizations, offering surgeons a more intuitive understanding of anatomical structures. Devices like the Apple Vision Pro may be used to create fully immersive virtual environments, although it is not currently approved as a medical device.
In clinical practice, Mixed Reality (MR)—which blends real and virtual environments with real-time interaction—has shown promise. MR has been used during Retrograde Intrarenal Surgery (RIRS) to reduce the risk of missed stones, and in Endoscopic Combined Intrarenal Surgery (ECIRS) to overlay anatomical data, improving puncture accuracy during Percutaneous Nephrolithotomy (PCN).
As an emerging field, further advancements will depend on enhanced imaging resolution, improved intrarenal navigation and integration of AI-driven real-time stone detection.

Complex Renal Stone: PCNL or RIRS or Combination?Mini-percutaneous nephrolithotomy (mini-PCNL) provides stone-free rate (SFR) 85 to 95 % in children with complex burdens, and recent systematic reviews report overall complications < 7 % and transfusion requirements ≈3 % when tracts ≤18 Fr are used. Its drawbacks are the need for percutaneous access, risk of bleeding, and potential parenchymal scarring, especially when multiple tracts are required.
Retrograde intrarenal surgery (RIRS) avoids renal puncture and shows the lowest incidence of high-grade complications (<1 %); contemporary series in preschool children describe initial SFRs of 60–78 %, with secondary procedures needed in up to one-third of cases because of narrow, tortuous ureters. Pre-stenting, staged dilation and longer operative time can offset its minimally-invasive appeal for stones ≥2 cm.
Endoscopic combined intrarenal surgery (ECIRS) merges an antegrade mini-PCNL channel with simultaneous flexible ureteroscopy. The first multicenter pediatric series and a 2024 comparative study confirm SFRs of 75–92 %, shorter hospital stay and lower fluoroscopy or transfusion risk than standalone PCNL despite treating more complex stones. Its limitations are the need for two skilled teams, specialized equipment and the Galdakao-modified supine Valdivia position, which lengthen setup and raise costs.
In summary, mini-PCNL remains the most efficient monotherapy for large or staghorn calculi; RIRS is ideal when bleeding risk or unfavorable percutaneous windows predominate; ECIRS offers the best compromise between clearance and morbidity where resources and expertise allow. Individualized, anatomy-based algorithms and further pediatric RCTs are still required.
ECIRSIn this session, we will demonstrate the technique about Totally-X-ray free ultrasound guided endoscopic combind intrarenal surgery in Galdakao modified supine Valdivia position.A Critical Appraisal on Percutaneous NephrolithotripsyPercutaneous nephrolithotripsy (PCNL) has evolved from a uniform prone, fluoroscopy-guided, large-tract technique into a precision endourological platform that emphasizes patient-tailored positioning, radiation-free puncture, miniaturized tracts, energy-efficient lasers and nascent robotic–AI augmentation. Contemporary evidence affirms that stone-free rates now approach a plateau, making safety metrics—bleeding control, infection prevention and intrarenal pressure modulation—the key differentiators among modern approaches. Miniaturized optics, suction-regulated sheaths and thulium-fiber or dual-wavelength laser consoles have collectively reduced hemoglobin loss and postoperative sepsis while preserving clearance efficacy. Future success will hinge on harmonizing technological innovation with rigorous evidence so that every incremental advance translates into measurable gains for both efficacy and safety in stone surgery.Echo guide Puncture in Supine PCNL: Tips and Tricks for an Efficient and Safe ProcedureMastery of ultrasound-guided supine PCNL begins with precise anatomical orientation. Color-Doppler mapping pinpoints the target calyx, which is punctured transpapillary with an echogenic-tip needle after artificial hydronephrosis is produced by retrograde ureteroscopic irrigation. A hydrophilic, floppy-tip yet stiff-shaft guidewire is then advanced through the needle, allowing atraumatic navigation of the collecting system under ureteroscopic visualization. Balloon dilation—used in place of sequential dilators—prevents guidewire dislodgement. When necessary, a through-and-through guidewire from flank skin to urethral meatus may be created to secure renal access. Finally, antegrade nephroscopy along this coaxial tract confirms unobstructed entry, provides panoramic inspection, and optimizes lithotripsy efficiency—all without fluoroscopy. Collectively, these steps deliver reliable access, eliminate radiation, and streamline stone clearance in a single, ergonomically favorable supine position.
