RUPTURE AND LACERATION OF THE BLADDER.
This occurs most commonly in oxen from obstruction of the urethra by a calculus. Similar obstruction in the horse causes most acute symptoms, calling for immediate relief, and rupture is a comparatively rare occurrence. Pench mentions a case resulting from a fall during an attack of colic, and with a full bladder. It has happened during lithotrity, or lithotomy, and even during parturition. Perforation by parasites has been noted and in one case by an osseous tumor of the pubic symphysis. In horses a fatal result is prompt, in cattle from 6 to 48 days.
Treatment surgical.
