Ultrasonography showed a nondistended urinary bladder that contained a possible intraluminal blood … MATERIALS AND METHODS The case was handled as per the international guidelines considering ethical standard and animal welfare issues. This condition should be suspected in any female puppy that has been dribbling urine since birth. All studies were assessed for ureteral ectopia, dilatation, tortuosity, … If the ureter is distended, it provides some clues that one may be dealing with an ectopic ureter. More than 95% of ectopic ureters are classified as intramural, in which the ureter enters the bladder in a relatively normal position, but then tunnels through the bladder and urethral walls prior to termination.

In female dogs, about 50% of the dogs will have dilated ureter(s); in male dogs up to 80%. These ureters enter at the urethra, vagina or uterus. An extramural ectopic ureter exits the kidney and bypasses the bladder altogether.

Ureteroneocystostomy in a dog with extramural ectopic ureters. Noël SM(1), Claeys S(1), Hamaide AJ(1). Ectopic hydroureters associated with hydronephrosis and contralateral renal agenesis may not show any abnormalities on routine renal biochemistry parameters. (a) The distal aspect of the ureter has been ligated and sectioned and is being pulled through a tunnel created in the dorsal aspect of the bladder wall in preparation for ureteroneocystostomy. The ectopic ureter may tunnel within the bladder tissue before opening in an abnormal location (intramural) or the distal ureter may implant into an abnormal area without tunneling (extramural). (b) The completed ureteroneocystostomy has been completed by placement of fine gauge absorbable sutures in a simple interrupted pattern to appose …

The flow of urine bypasses the bladder and affected animals typically leak urine from birth.

Urine flows from the kidney into the bladder through these ureters, but sometimes one or both do not lead all the way to the bladder, so they bring urine wherever they do lead, which may be the uterus, vagina, or urethra.
