title: Minimally invasive endourologic management of calculi in continent urinary reservoirs.
abstract: This study was done to determine whether minimally invasive endourologic management of calculi in continent reservoirs can be done effectively without compromise of urinary continence. Four patients with continent urinary diversions (1 Indiana pouch and 3 Kock pouches) were managed with trans-stomal pouchoscopic ultrasonic lithotripsy (n = 2), prone position extracorporeal shock wave lithotripsy (n = 1), or a "sandwich" combination of these (n = 1) for stone burdens up to 20 cm2. Total hospital stay ranged from one to four (mean = 2.6) days. All 4 patients were initially rendered stone free, and, with follow-up as long as twenty-five months, only 1 has had a recurrence. No patient experienced stomal leakage or other complications. This study suggests that minimally invasive endourologic management of calculi in continent urinary reservoirs can be done safely and effectively to obviate the need for more invasive percutaneous approaches or open surgery, even for some patients with large stone burdens.
