Urethral pressure profilometry in mares

Abstract

Summary A technique was developed for recording urethral pressure profiles ( upp ) in mares. Profiles were obtained from 12 clinically normal mares and from 3 mares with urinary incontinence. Variables measured on the profile included intravesicular pressure and maximal urethral closure pressure. The mean maximal urethral closure pressure of the incontinent mares was significantly less ( P ≤ 0.001) than that of the normal mares. The technique is simple and reliable for objectively evaluating urethral pressures in mares.
