Limited information exists about surgical techniques to treat incontinence in cats. In this case, a four-month-old female entire domestic shorthair cat was presented with a history of severe urinary incontinence. Contrast studies supported a diagnosis of genitourinary and urethral dysplasia with urethral sphincter mechanism incompetence (USMI). The incontinence was unresponsive to medical treatment. At 10 months old, an artificial urethral sphincter (AUS) was surgically placed, restoring urinary continence completely. This case report demonstrates that an AUS—a technique previously described only for treatment in dogs with refractory incontinence—may be suitable for the management of refractory USMI in cats with congenital urinary incontinence. Also, in cases of persistent or recurrent incontinence, and at any time subsequent to the surgery, an increase in pressure around the urethra can be achieved, non-invasively, by inflating the AUS's percutaneous occluder.
