SURGICAL-TREATMENT OF MALE DOGS WITH URINARY-INCONTINENCE DUE TO URETHRAL SPHINCTER MECHANISM INCOMPETENCE

A modified technique for fixation of the deferent ducts to the abdomin al wall as a therapy for urinary incontinence caused by urethral sphin cter mechanism incompetence (USMI) in male dogs is described, and the results in seven dogs are reported. The goal of this treatment was to achieve an effect similar to colposuspension in female dogs with USMI. An increase in urethral length of an average of 28 mm was obtained (r ange, 5 to 50 mm, measured radiographically). Preoperatively, the neck of the bladder was located intrapelvically in five of seven dogs. Pos toperatively, the neck of the bladder was located intra-abdominally, n ear the caudo-ventral abdominal wall, in all dogs. After a follow-up p eriod of 12 to 49 months, the response to surgery, based on lack of or decrease of incontinence, was excellent in three dogs, good in anothe r three, and poor in one dog.
