[Urinary incontinence due to congenital ectopic ureter in a dog]

Ectopic ureter was diagnosed by urography and vaginography in a 3 month old puppy. Clinical signs include urinary incontinance contact dermatitis around vulva and anus. Urography revealed dilatation of the left ureter and pelvic kidny. It was difficult to show clearly the course of ureter into the vagina by this technique. Vaginography was performed under radioscopy facilities and spot radiographs were taken during radioscopy which showed clearly existence of contrast media in the left ureter. No surgical intervention attempted because of owner disagreement. At necropsy both ureter were ectopic but there was not any dilatation of right ureter probably due to the complete emptying of urine into the blader and vagina simultaneously
