Laparoscopic Nephroureterectomy for Nonfunctioning Ectopic Pelvic Kidney with Ectopic Ureter and Lower Ureteral Stricture Opening in the Vestibule of the Vagina But No Incontinence: Challenges in Diagnosis and Surgical Dissection.

Failure of mature kidney to reach its natural location in renal fossa is termed as renal ectopia. Ectopic kidney can be found in pelvic, iliac, abdominal, and thoracic location. Pelvic ectopia has been estimated to occur in 1 of 2100 to 3000 autopsies. In contrast, ectopic ureters are commonly associated with complete renal duplication. Commonest presentation in females in continuous urinary incontinence with normal voiding habits as ectopic ureter open below the bladder neck in urethra or vagina. An ectopic kidney with ectopic ureter is extremely rare congenital anomaly. We report a 36-year-old woman presenting with left lower abdomen pain with no history of fever, dysuria, or urinary incontinence. On evaluation, she was found to have left nonfunctioning ectopic pelvic kidney with ectopic ureter opening in the vestibule of the vagina, which was managed with laparoscopic nephroureterectomy. One should suspect an ectopic ureter in a female presenting with continuous urinary incontinence since birth. However, diagnosis is challenging when clinical presentation is unusual with no urinary incontinence as seen in the index case. Detailed local examination in correlation with imaging is key for diagnosis and rule out other congenital anomalies. Laparoscopic approach in such clinical scenario is a safe and feasible option.
