Abstract:
The rare finding of lower pole ureteropelvic junction obstruction and incomplete renal duplication is discussed in 5 children. The children were divided into 2 groups, with short (less than 0.5 cm.) and long (greater than 4 cm.) lower ureteral segments. Short ureteral segment obstruction was managed by total excision of the narrow ureteral segment and end-to-side pyeloureterostomy. Obstructions associated with long lower ureteral segments were treated by excising the ureteropelvic junction and performing a standard Anderson-Hynes pyeloplasty. A thorough preoperative evaluation is helpful for successful management.
