Congenital ureteral ectopia is an abnormality in which one or both ureters terminate at a position other than the urinary bladder trigone. This condition is the most frequent reason for early (since birth or weaning) urinary incontinence in dogs (Fossum 2007, Ho and others 2011, Reichler and others 2012). In such cases, early surgical correction of ureteral ectopia is required. In cases of delayed surgical intervention, permanent urinary incontinence, recurrent urinary tract infections, and hypoplasia of the urinary bladder can be noticed (Holt 2008, Ho and others 2011). Little is known about the effective treatment of neutered bitches with concurrent ureteral ectopia and intrapelvic urinary bladder. Ho and others (2011) found only two such patients in a group of 33 dogs. These dogs were treated surgically (correction of ectopic ureters and colposuspension) without satisfactory effects (incontinence after surgery).

This short communication describes the results of surgical treatment of incontinent adult bitches with ureteral ectopia, and small (hypoplastic) intrapelvic urinary bladder.

Nine adult neutered bitches (4.5±2 years old and 34.6±6.59 kg bodyweight), with urinary incontinence were referred (Table 1).

Summary of surgical correction of ureteral ectopia and intrapelvic urinary bladder in nine neutered adult female dogs with urinary incontinence

The dogs were previously treated pharmacologically (phenylpropanolamine, oestriol and some antibiotics), due to presumed diagnosis of urethral sphincter mechanism incompetence and recurrent episodes of urinary tract infection. Such treatment only resulted in short-term remission of clinical symptoms. Identification of ureteral ectopia included the use of excretory urography and intraoperative examination. Imaging studies were performed in dogs positioned in the right lateral, right oblique, left oblique and dorsal recumbency, and evaluated according to guidelines described by Samii and others (2004). Contrast studies were suggestive of ureteral ectopia. A small intrapelvic urinary bladder was also found in all the dogs (Figs 1 and 2). The urinary bladder …
