John DenstedtCanada Speaker UAA Lecture: Innovations in Renal Stone SurgeryInnovations in Renal Stone Surgery John Denstedt MD FRCSC Professor of Urology Schulich School of Medicine and Dentistry Department of Surgery Western University London Canada Recent years have seen a burst of innovation in techniques for minimally invasive treatment of renal stones. Current guidelines recommend either shock wave lithotripsy or retrograde intrarenal surgery {RIRS} for stones smaller than 2cm and percutaneous renal stone removal for calculi greater than 2cm in maximal diameter. Progress in mini percutaneous stone removal {mPCNL} has facilitated expansion of antegrade techniques to stones smaller than 2cm while concurrently RIRS has seen indications expand to include larger stones than previously considered. Most randomized trials have demonstrated similar operating times, hospital stays and complications comparing RIRS and MPCNL however stone free rates are generally documented to be improved with a percutaneous approach. Technology continues to advance and the development of flexible deflectable ureteral access sheaths with suction capability offer the possibility of improved stone free rates with RIRS while also decreasing intrarenal pressure, thus reducing the incidence of sepsis and other complications. This is challenging the traditional concept of limiting retrograde ureteroscopy to stones less than 2cm in diameter. This lecture will review the current literature on RIRS for intrarenal stones greater than 2cm, outlining expectations for the main parameters of stone free rate, complications and operating efficiency. Currently available technology and techniques will be presented allowing participants to take practical tips and tricks back to day to day urologic practice.

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. Suture to urethra and ureters. It is often performed entirely intracorporeally with the da Vinci Xi system.

Stephen A. BoorjianUnited States Speaker AUA Lecture: 2025 Update of AUA and EAU NMIBC GuidelinesBoth the American Urological Association (AUA) and European Association of Urology (EAU) have developed guidelines for the management of non-muscle invasive bladder cancer (NMIBC). While subtle differences in several aspects of these guidelines exist which merit mentioning, both guidelines emphasis the concept of risk stratification. In particular, understanding the criteria which classifies patients with NMIBC as high risk avoids undertreatment of the patients most likely to experience disease progress. Likewise, recognizing the indications for cystectomy among high risk NMIBC patients is critical to optimize survival. Meanwhile, continued options emerge for patients classified as having BCG unresponsive NMIBC, such that knowledge of that definition as well as current management strategies for these patients facilitates contemporary practice.From Bench to Bedside - A Comprehensive Overview of Kidney CancerEvaluation of patients with a newly identified renal mass includes dedicated cross-sectional imaging for appropriate characterization. Genetic syndromes which include renal cell carcinoma (RCC) are increasingly understood, and indeed knowledge of the intracellular pathways of these conditions has facilitate rationale drug development for kidney cancer. Managing patients with a small renal mass involves a critical assessment of competing risks inherent to the tumor, the patient (underlying comorbidity status), and the proposed treatment. Renal mass biopsy may play a role in select cases for additional information/risk stratification. The safety of active surveillance is being increasingly demonstrated as longer-term follow-up matures. Meanwhile, select patients with high risk disease now have the option of adjuvant immunotherapy following surgical resection. In the setting of metastatic RCC, again risk stratification plays a critical role in the decision for – and timing of – cytoreductive nephrectomy, particularly in the contemporary era of checkpoint inhibitor therapies.Real World Experience in the Management of Upper Tract Urothelial CarcinomaThe biggest challenging in managing upper tract urothelial carcionma (UTUC) remains accurate staging of tumors at diagnosis. Given the limited ability of contemporary staging methods, clinical risk stratification models have been developed to assist in providing risk-based treatment recommendations. For example, endoscopic management (e.g., ablation) represents the recommended first line approach for patients with low risk disease. Importantly, follow-up for these patients should include endoscopic re-evaluation. The value of testing patients with UTUC for Lynch syndrome is also critical to recognize. A role for neoadjuvant chemotherapy is being increasing explored for patients classified with high-risk UTUC, while several options exist for adjuvant chemotherapy and immunotherapy for patients with adverse pathology at surgical resection. Continued investigation into prevention of postoperative intravesical recurrences in patients with UTUC is warranted given the frequency of metachronous tumor development in the bladder among these patients.Updates on MIBC and Advanced Bladder Cancer: Where do We Stand in 2025While neoadjuvant chemotherapy prior to radical cystectomy has been demonstrated with randomized trial data to improve survival for patients undergoing radical cystectomy, nevertheless utilization is often restricted by misunderstandings regarding patient eligibility factors. As such, defining eligibility criteria will facilitate increased adoption. Likewise, new data indicates a role for adjust immunotherapy in select patients following surgery as well. Moreover, important recent evidence on the role of extended lymph node dissection and the opportunities for preserving sexual function after cystectomy by modifying surgical technique are critical to review in order to optimize future patient outcomes. Further, recent advancements in systemic therapy options for patients with metastatic urothelial carcinoma have led to unprecedented survival rates.Revisit on Testicular Tumors-What we Learned from past and Prepared for the FutureGerm cell tumor (GCT) progression typically occurs in a predictable sequence of disease spread to the retroperitoneum first and then distant metastases. Understanding the role of serum tumor markers at various disease stages is critical for guideline-concordant management and to optimize patient outcomes, avoiding both undertreatment and overtreatment. For patients with seminoma, retroperitoneal lymph node dissection now represents an option for patients with low volume retroperitoneal lymph node disease, with the goal of avoiding the long-term toxicities associated with chemotherapy and radiotherapy. For patients with residual postchemotherapy masses in seminoma, increasing evidence suggests that PET scans should be utilized/interpreted with caution, and that in the absence of mass growth continued follow-up may be the strategy for most patients. Similarly, for patients with nonseminomatous GCTs (NSGCT) and equivocal retroperitoneal lymph nodes at presentation, re-scanning after an interval of approximately 6-8 weeks may be preferable to initial treatment, as many of these nodes represent benign processes and as such will resolve. Nevertheless, postchemotherapy retroperitoneal lymph node dissection remains a critical component of the management of patients with NSCGT and a residual mass. Risk Stratification and Contemporary Management of Biochemical RecurrenceBiochemical recurrence (BCR) has been reported in up to 35% of patients following radical prostatectomy. Understanding the natural history and clinicopathologic risk factors associated with disease progression is critical to facilitate an individualized treatment approach. Likewise, recognizing the details of treatment delivery with salvage radiotherapy is necessary to optimize outcomes. Further, as data emerge on the utilization of systemic therapy for non-metastatic BCR, being able to contextualize reported outcomes with patient age, comorbidity status, and disease risk will enhance appropriate care delivery.

Bannakij LojanapiwatThailand Moderator 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.

David PensonUnited States Speaker Comparison of Various Treatment Options for Localized Prostate CancerThere are numerous therapeutic strategies used to treat localized prostate cancer, each with unique advantages and disadvantages. Furthermore, prostate cancer itself is heterogeneous with some tumors being indolent and others being more aggressive. We will from the presentation by looking at outcomes separately in patients with favorable prognosis and those with unfavorable prognosis, based upon baseline clinical characteristics. We will first compare cancer control and mortality outcomes amongst the various options. We will then present data on patient-reported outcomes. At the conclusion of the presentation, attendees will have a better understanding of outcomes following treatment for localized prostate cancer and will be better prepared to counsel patients newly diagnosed with this common malignancy.Updates on Combination Therapy for Advanced Prostate CancerOver the past decade, there are have been significant advances in the treatment of metastatic prostate cancer. Randomized clinical trial data have demonstrated that combination therapies are superior to monotherapy in terms of cancer control and survival. Various treatment options will be discussed for metastatic castrate-sensitive and -resistant prostate cancer. These will be compared in terms of efficacy and side effect profiles to aid in treatment selection in this The Startup of An Academic Urologist - How to Build up Your Team in Clinical ResearchMany young academic urologists wish to perform clinical research at their institution. Often, however, this is challenging due to lack of resources or time. In this presentation, we will discuss how to build a clinical research program, including identifying what types of individuals need to be part of the team and what sort of resources are required for success. While American examples will often be used, information from this presentation will still be applicable globally.A Programmatic Approach to Prostate Cancer ScreeningProstate cancer screening has advanced beyond annual PSA testing. We now have numerous tools available to aid in identifying men at risk for harboring clinically significant prostate cancer, including MRI and various novel biomarkers. In this presentation, we will review these modalities and lay out a systematic approach to screening in 2025.
