Management of incontinence following pre-pubic urethrostomy in a cat using an artificial urethral sphincter.

Abstract

A 14-year-old male neutered domestic shorthair cat presented with a 4-year history of urinary incontinence following prepubic urethrostomy. Physical examination confirmed peristomal dermatitis, urine scalding and constant urine leakage. Haematology, serum biochemistry and urinalysis were unremarkable. Ultrasonography revealed a non-distended urinary bladder. An artificial urethral sphincter mechanism, with subsequent incremental inflation of the cuff 6 weeks later, resulted in complete resolution of clinical signs, return to normal urinary function and excellent quality of life. The cat was still continent at 5-year follow-up. Further studies including additional cases are required to highlight effectiveness and harms of the procedure.
