- Ruchika Talwar hosts a discussion with Greg Tasian and Nicolas Fernandez about surgical variations in managing pediatric kidney stone disease. They discuss the PKIDS study, involving 30 centers, which examines surgical preferences and outcomes for children aged 8-21 undergoing ureteroscopy, shockwave lithotripsy, and percutaneous nephrolithotripsy. Dr. Fernandez highlights the variability in surgi...

- Andrei Cumpanas presented a study on ureteral strictures following ureteroscopic ureteral wall injury, highlighting a previously unidentified concern. The study aimed to determine the risk of post-ureteroscopic ureteral stricture formation based on the depth of injury into the ureteral wall, revealing that stricture rates increase significantly when the ureteral wall is partially or fully transgre...

- Jamie Landman presented initial clinical experience with a combined robotic mini-percutaneous nephrolithotomy (mini-PCNL) and ureteroscopic lithotripsy platform for treating a large left-sided kidney stone burden. The Monarch Robotic Platform, featuring a robot with three arms, enables precise control of the ureteroscope and percutaneous instruments. The procedure involves robotic ureteroscopy, st...
