Submucosal Collagen Injection for Management of Urinary Incontinence Following Urethral Stent Placement.

An 8-year-old, entire, male British Bulldog was referred for a week-long history of severe stranguria and dysuria. A prostatic wash was diagnostic of prostatic carcinoma. A transluminal urethral stent was placed in the proximal urethra, which resulted in resolution of the urinary obstruction, however, the dog developed severe urinary incontinence after the procedure. Cystoscopically-guided submucosal collagen injections were performed immediately proximal to the os penis. The dog's incontinence resolved with a single collagen injection for the 10-month follow-up period.
