Abstract：Duplicated renal-ureteral malformation is one of the common congenital malformations of the urinary sys-tem.Most cases present as unilateral lesions,while the coexistence of bilateral duplicated renal-ureteral malformation and uni-lateral ectopic kidney is rare.Most patients have no significant clinical manifestations;however,when hydronephrosis occurs due to ureteral stenosis or obstruction,it is easily confused with simple renal cysts.This article reports a case of bilateral dupli-cated renal-ureteral malformation complicated with giant hydronephrosis in one ectopic kidney,aiming to provide a reference for clinical treatment.
