An 11-year-old neutered male domestic short-haired cat was referred to Azabu University Veterinary Teaching Hospital for a detailed examination of recurrent azotemia. Extravasation of urine around the left kidney was suspected, and renal pelvis rupture was diagnosed during exploratory surgery, which revealed a defect in the ventral aspect of the left renal hilum and urinary leakage through the defect. Pyeloplasty was performed using a bladder wall patch. One week postsurgery, the procedure was repeated to repair recurrent urinary extravasation observed near the surgical site. After two operations, the cat made an uneventful postsurgical recovery.
