Uncrossed complete ureteral duplication with caudal orthotopic orifice and ureterocele

A case is reported 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 orifice was associated with a small undilated ureter. The orthotopic kidney was hydronephrotic, and the ectopic kidney was small and non-functioning. 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.
