Pure laparoscopic total ureterectomy for urothelial carcinoma that occurred in the ureteral stump after nephrectomy: A case report

摘要

Primary carcinoma of the ureteral stump following a radical nephrectomy is rare, and it is even rarer that the cause of the nephrectomy is renal cell carcinoma (RCC). Treatment by complete ureterectomy with a bladder cuff is considered as the standard treatment. We report a case of a 70-year-old female with urothelial carcinoma with glandular differentiation that occurred in the ureteral stump after nephrectomy for left RCC. We performed a novel technique of pure laparoscopic resection of the ureteral stump with a bladder cuff.
