Management and complications following trigonal-colonic anastomosis in a dog: five-year evaluation.

Urinary diversion procedures in the dog have been described for both benign and malignant processes involving the bladder, urethra, or both. These procedures are performed rather infrequently, primarily because of the potential complications associated with urinary diversion into an intact gastrointestinal system. A case managed for five years following trigonal-colonic anastomosis for lymphocytic-plasmacytic urethritis is presented, along with a review of urinary diversion techniques. Postoperative management recommendations following urinary diversion are discussed.
