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

A case of complete response to avelumab plus axitinib combination therapy for metastatic clear cell renal cell carcinoma in a kidney undergoing dialysis

Introduction Combination therapies of immune checkpoint and tyrosine kinase inhibitors for end‐stage kidney disease and patients on hemodialysis need careful consideration as few case reports provide suitable management decisions. Case presentation A 70‐year‐old man who had undergone hemodialysis for 6 years due to nephrosclerosis. Avelumab plus axitinib combination therapy was performed for repeated lung metastasis, and a complete response was achieved without major side effects. Conclusion A complete response was achieved after Ave plus Axi combination therapy for clear cell renal cell carcinoma in a patient undergoing dialysis. This suggests that Ave plus Axi combination therapy may be safe and effective for dialysis patients
