Modified prepubic urethrostomy with body wall tunneling: Description of technique and long-term outcome in eight male cats.

Abstract

OBJECTIVE: To describe the procedure, complications, and long-term outcome of cats that underwent a modified prepubic urethrostomy (mPPU) technique for the management of proximal urethral obstructions. ANIMALS: Eight male cats. STUDY DESIGN: Short case series. METHODS: Medical records were reviewed for signalment, diagnostic investigation, details of the surgical procedure, and complications of cats that underwent mPPU. RESULTS: mPPU was well tolerated by all patients, and no intraoperative complications were reported. The duration of follow-up ranged from 13 to 84 months (median 19 months). Early postoperative skin scalding around the stoma associated with mild urinary incontinence during recumbency occurred and was self-limiting in all patients. Two cats required surgical revision at 5 and 6 months, respectively, due to a progressive weight gain and accumulation of abdominal fat around the stoma, causing a partial stomal obstruction. Resolution of clinical signs was reported in both patients. CONCLUSIONS: mPPU was easy to perform and offered favorable outcomes in this cohort of cats.
