Uroabdomen in an Umblachery bull- A case report

A 4-year-old Umblachery bull was presented to the Large Animal Medicine Unit at the Veterinary Clinical Complex, Veterinary College and Research Institute, Orathanadu, with a 5-day history of abdominal distension, anorexia, anuria, and absence of defecation. Clinical examination revealed depression, dehydration, elevated respiratory rate, bilateral abdominal distension with fluid thrill. Trans-abdominal ultrasonographic examination revealed the presence of anechoic free fluid in the abdominal cavity. Ultrasound-guided abdominocentesis yielded a light yellow-colored modified transudate with a low specific gravity of 1.013 and a distinct ammonia odor. Haematobiochemical examination revealed PCV= 41.8%, WBC=10,300 cells/cumm, elevated blood urea nitrogen, creatinine and lactate levels. Peritoneal fluid showed increased levels of blood urea nitrogen and creatinine compared to that of serum levels. Based on ultrasonographic examination of abdomen and peritoneal to serum creatinine ratio, the case was confirmed as uroabdomen. The animal was administered with strepto-penicillin, flunixin meglumine and supportive fluid therapy but the animal died due to delayed presentation and uraemia.
