Abstract
A case is reported in a child of uncrossed complete left ureteral duplication with the orthotopic ureteral orifice opening caudal to the ectopic orifice. Whereas the caudal orthotopic orifice was associated with a ureterocele and megaloureter, the cranial ectopic orifice was associated with a small undilated ureter. The orthotopic kidney was hydronephrotic, and the ectopic kidney was small and nonfunctioning. The ureterocele was excised together with the megaloureter and the small ectopic kidney also was removed. The undilated ectopic ureter was transplanted to the orthotopic kidney by performing a ureteroneocystostomy distally and ureteropelvic anastomosis proximally.
