A 1‐year‐old female spayed French Bulldog was referred to the Interventional Radiology and Endoscopy Service for evaluation of urinary incontinence with partial response to medical management (phenylpropanolamine). Cystourethroscopy and retrograde ureteropyelogram were performed and revealed multiple congenital abnormalities including; a duplex renal system of the left kidney with one normal ureter with an intravesicular ureteral orifice and one extramural ectopic ureter with an associated branching and ureteral diverticulum. A dual vagina was also noted. Left neoureterocystostomy of the extramural ectopic ureter was performed and a temporary ureteral stent was concurrently placed and removed cystoscopically one month later, leaving the patient with two patent left ureters. Thirty‐four months later the patient is mildly incontinent with no other comorbidities.
