Advancements in Ureteroscopy for Stone Management
How is suction technology changing what it means to be “stone-free” after ureteroscopy? On this episode of BackTable Urology, Dr. Ruchika Talwar welcomes Dr. Karen Stern, endourologist at Mayo Clinic Arizona, for a practical discussion of how ureteroscopy is evolving in the era of suction. They discuss how thin-slice CT has revealed just how much stone typically remains after surgery, why dusting versus fragmenting is now a patient-dependent choice, and what to consider when selecting between suction sheaths, aspiration scopes, and traditional access.
