Ann. Méd. Vét., 2004, 148 (2), pp 103-109 Ectopic ureters in the dog: literature review and case reports in 3 male dogsPOLLACI E., BALLIGAND M., HAMAIDE A.Abstract :
Ureteral ectopia is a congenital abnormality in which one or both ureters does not open into the bladder. This is the most common cause of urinary incontinence in the immature bitch, but is rarely diagnosed in the male dog. Some breeds are predisposed (Siberian Husky, Labrador, Golden Retriever). Typical clinical signs are a continuous (but sometimes intermittent) leakage of urine since birth, although micturition can be normal. Other associated congenital abnormalities can be present (hydronephrosis, double vagina, cryptorchidism). Diagnostic techniques include excretory urography coupled with
a pneumocystography, vaginourethrography, cystoscopy, vaginoscopy, and ultrasonography. Ectopic ureters can be unilateral
(most commonly) or bilateral, and they are either intramural or extramural. Surgical correction is the treatment of choice. After a successful surgery, some patients can still show some degree of incontinence, due to the presence of urethral sphincter mechanism incompetence. This residual incontinence can be resolved in the majority of the cases with the use of alpha-adrenergic agents. Get the PDF Contact person : Annick.Hamaide@ulg.ac.be |
