A 7-year-old male rabbit showed a hunched posture and abdominal pain with the main complaint of loss of appetite and vigor. In radiographic examinations, stones were detected in the right and left renal pelvises. Medical treatment was initiated with analgesics and subcutaneous infusion. On day 8, stones in the right renal pelvis were found to have migrated into the ureter, causing ureteral obstruction. As abdominal ultrasound examination revealed distention of the right renal pelvis and ureter, right ureterotomy was performed to remove the stones, which were found to be mainly calcium oxalate. The postoperative course was uneventful; however, the patient returned to our hospital on day 21 because of increased squatting posture and urinary frequency. Distention of the left renal pelvis and ureter was noted with migration of stones from the left renal pelvis into the ureter. Left ureterotomy was performed for stone removal, and postoperative recovery was uneventful. Seven weeks after the second surgery, the rabbit exhibited loss of vigor and pollakiurea, and newly formed stones were detected on radiographs. The rabbit was treated with infusion and analgesics if needed, and its daily activity was almost the same as before. One year and 10 months after the second surgery, growth of stones in the right and left renal pelvises and elevation of the values of BUN and creatinine were seen, and the patient died of aggravated renal dysfunction 2 years and 4 months after the second surgery.
