Introduction And Hypothesis:
A duplicated collecting system is the most common birth defect related to the urinary tract and is more common in women. Approximately 0.7% of the healthy adult population and 2-4% of patients with urinary tract symptoms have duplicated ureters. This video discusses the presentation, evaluation, and treatment of duplicated urinary collecting systems, and presents a case of duplicated collecting system with ectopic ureteral implantation at the vaginal introitus.
Methods:
We present the case of a 56-year-old presenting with a history of incontinence and recurrent urinary tract infections starting in adolescence and her workup for a duplicated collecting system, as well as subsequent surgical management with narrated footage. The patient was counseled that a distal ectopic ureter remnant could serve as a nidus for infection and the patient elected to undergo complete excision of the distal ectopic ureter.
Conclusion:
Duplicated urinary collecting systems are the most common birth defect related to the urinary tract and can be frequently encountered by the pelvic surgeon. Knowledge of the presentation and workup of a suspected duplicated collecting system is important in carrying out appropriate treatment.
