An 11-month old, Piedmontese bullock was admitted to the Department of Veterinary Science, University of Turin, for urolithiasis and suspected uroperitoneum owing to urinary bladder rupture. A first episode of uroperitoneum had been treated surgically one week previously. On admission, the animal underwent physical and haematological examination, followed by transabdominal ultrasonography and biochemical screening. Clinical and laboratory findings confirmed the recurrence of uroperitoneum, possibly secondary to the previously failed surgical approach. During surgery, urine leakage from the previously treated tear was clearly visible, together with a large necrotic area surrounding the tear. To close the defect, we created a peritoneal flap. For tissue approximation we used a continuous barbed suture material, which obviated the need for knots to secure the leading and terminal ends of the suture. Postoperative monitoring included transabdominal ultrasonography and biochemical profile tests, performed at 10 and 30 days after surgery. Two months after discharge, a telephone follow-up confirmed the positive outcome of the procedure. The creation of a peritoneal flap allows for effective sealing of a bladder tear with necrotic edges. The use of barbed suture greatly simplifies the entire procedure.
