摘要
The use of memory metallic stents for the urinary tract in pediatric patients has not been reported. The authors report on 2 patients with urinary tract diso rders who were successfully treated with a memory metallic stent. A thermoexpand able, nickel- titanium alloy stent was placed at the urethroureteral junction o f a 4- year- old boy with ureteral stenosis associated with cloacal exstrophy for 18 months and at the urethra of a 2- year- old girl with ischuria after a repair of cloacal anomaly for 6 months. Temporary insertion of a memory metallic stent is a safe and effective alternative for organic stricture or functional o bstruction of the urinary tract in pediatric patients.
