Traumatic Membranous Urethra Rupture in a Foal: A Case Report

Öz

Urethral ruptures can be a life-threatening emergency that may lead to uroperitoneum. Uroperitoneum can result from urethral ruptures, which can be fatal. This case report aimed to describe the clinical findings and treatment outcomes of a traumatic membranous urethral rupture in a 15-day-old Ambling foal. The foal had been wounded by a wild animal 9 days prior, and despite treatment, the foal's condition worsened, the owner brought the animal to the Faculty of Veterinary Medicine Research and Practice Animal Hospital. On physical examination several wounds in the pubic and inguinal regions were identified, some of which were complicated by a fistula. The rectal body temperature, heart rate, respiration rate, and capillary refill time were low. In laboratory findings, lymphopenia, eosinopenia, and mild anemia decreased partial oxygen pressure with acidic blood pH were observed. Sutures were applied to the urethral tear and wound care was provided. On the fifth day after surgery, the owner called the hospital to report that the foal was constipated and had signs of colic. Rectal olive oil use was recommended, and surgery was arranged for the following day. Despite cardiac resuscitation and emergency treatments, the foal couldn’t be saved during the operation due to cardiac arrest. In conclusion, even for unrelated surgical operations involving the gastrointestinal system, gastrointestinal outcomes of surgery and anesthesia must be considered.
