Recurrent Perineal Hernia in a Female Cat Diagnosed by Positive-Contrast Vaginourethrocystogram.

Abstract

A 9 yr old female spayed domestic shorthair was presented with a 12-day history of stranguria. Six years previously, the cat had a bilateral perineal herniorrhaphy with cystopexy and pubic osteotomy. At presentation, survey radiographs and a positive-contrast vaginourethrocystogram were performed, which revealed cystolithiasis and recurrent bilateral perineal hernias with bladder retroflexion. A cystopexy was repeated, followed by bilateral perineal repairs using the internal obturator muscle flap transposition. To the authors' knowledge, this is the first reported case of a perineal hernia with recurrent bladder retroflexion after cystopexy diagnosed with positive-contrast vaginourethrocystogram in a female cat.
