title: Persistent Urinary Incontinence After Nephrectomy: A Case of Inverted-Y Ureteral Duplication with Ectopic Ureteral Insertion into the Vagina.
abstract: Inverted-Y ureteral duplication is one of the rarest anomalies of ureteral branching. We encountered a 20-year-old female patient with persistent incontinence even after nephrectomy for ectopic ureteral insertion into the vagina. She had inverted-Y ureteral duplication between the bladder and vagina, and urine was being transported from the bladder to the vagina. To the best of our knowledge, this is a rare case of inverted-Y ureteral duplication with ectopic ureteral insertion into the vagina as well as the ureter into the bladder, which became apparent due to persistent urinary incontinence even after nephrectomy.
