A case of severe ureteral injury repaired by renal autotransplantation with an iliac vein patch using bovine pericardium.

Introduction:Renal autotransplantation is considered a surgical procedure for extensive ureteral defects. Herein, we report a case of severe ureteral injury repaired by laparoscopic nephrectomy and renal autotransplantation with an iliac vein patch using bovine pericardium. Case presentation:A 56-year-old woman who had previously undergone gynecological surgery complained of right-sided abdominal pain. She was then later diagnosed with a right middle ureteral injury with a 5-cm long defect. We performed retroperitoneal laparoscopic nephrectomy and renal autotransplantation. As the iliac vein was fragile, venous patching using bovine pericardium was performed. The patient's renal function was well preserved after surgery. Conclusion:Laparoscopic nephrectomy and renal autotransplantation is an effective method for repairing severe ureteral injury with the preservation of renal function. A venous patch using bovine pericardium might be considered as a replacement for a fragile vein.
