Six years after living donor nephrectomy to his daughter, the 78-year-old donor presented to the emergency room with anuria for approximately 12 h. Only arterial hypertension, mildly reduced kidney function (eGFR 54 mL/min), and benign prostatic hyperplasia were known as preexisting medical conditions. In sonography, hydronephrosis III° was visible in the right single kidney. Ureterorenoscopy revealed an occlusive tumor in the right proximal ureter, which was treated via double J stent. Biopsy showed focal invasive papillary urothelial carcinoma of G2 high grade. Preoperative staging did not show any signs of lymph node or distant metastases. For therapeutic options, nephroureterectomy with consecutive need for dialysis was discussed versus partial ureteral resection with in situ ureteral reconstruction versus nephroureterectomy with partial ureteral resection and kidney autotransplantation. Eventually, laparoscopic right nephroureterectomy was performed with back-table preparation and tumor resection, followed by ipsilateral autotransplantation. The patient developed postsurgical acute kidney failure due to ischemia/reperfusion with a maximum serum Cr of 5.66 mg/dL (eGFR 10 mL/min), which quickly resolved. The papillary invasive urothelial carcinoma was graded pT1 pTis G2 high grade R0. Regular follow-ups showed no sign for cancer recurrence in computer tomography or cystoscopy; serum Cr was at 1.87 mg/dL (eGFR 53) 12 months after surgery.
