A 46-year-old Japanese man was diagnosed with a left renal pelvic carcinoma and a contralateral hypoplastic kidney. The tumor was adjacent to the renal pelvis and was considered too difficult to completely resect in situ. The patient was treated by ex vivo partial nephrectomy of the left kidney followed by autotransplantation of the remaining renal segment. A pathologic evaluation revealed a transitional cell carcinoma, G2, pT3. Graft function recovered satisfactorily postautotransplantation and no significant complications developed during the postoperative period. The patient is alive and doing well 12 months postoperatively with no evidence of tumor recurrence.

ABSTRACT: We report the technique of and initial experience with retroperitoneal laparoscopic live donor right nephrectomy for purposes of renal allotransplantation and autotransplantation. A total of 5 patients underwent retroperitoneoscopic live donor nephrectomy of the right kidney for autotransplantation in 4 and living related renal donation in 1. Indications for autotransplantation included a large proximal ureteral tumor, a long distal ureteral stricture and 2 cases of the loin pain hematuria syndrome. In all cases a 3-port retroperitoneal laparoscopic approach and a pelvic muscle splitting Gibson incision for kidney extraction were used. In patients undergoing autotransplantation the same incision was used for subsequent transplantation. All procedures were successfully accomplished without technical or surgical complications. Total mean operating time was 5.8 hours and average laparoscopic donor nephrectomy time was 3.1 hours. Mean renal warm ischemia time, including endoscopic cross clamping of the renal artery to ex vivo cold perfusion, was 4 minutes. Average blood loss for the entire procedure was 400 cc. Radionuclide scan on postoperative day 1 confirmed good blood flow and function in all transplanted kidneys. Mean analgesic requirement was 58 mg. fentanyl. Mean hospital stay was 4 days (range 2 to 8), and convalescence was completed in 3 to 4 weeks. In the occasional patient requiring renal autotransplantation live donor nephrectomy can be performed laparoscopically with renal extraction and subsequent transplantation through a single standard extraperitoneal Gibson incision, thus, minimizing the overall operative morbidity. Furthermore, these data demonstrate that live donor nephrectomy of the right kidney can be performed safely using a retroperitoneal approach with an adequate length of the right renal vein obtained for allotransplantation or autotransplantation.The Journal of Urology 12/2000; 164(5):1500-4.

ABSTRACT: We aimed to determine the ability of partial nephrectomy to prevent end-stage renal disease and tumor recurrence or progression in patients with upper tract urothelial carcinoma. Retrospectively, eight patients undergoing partial nephrectomy for upper tract urothelial carcinoma were identified and their medical records reviewed. All patients had imperative indications for nephron sparing, and diagnosis of upper tract urothelial carcinoma not adequately amenable to endoscopic management. Although three patients suffered acute tubular necrosis, only one required postoperative hemodialysis. During the follow-up period 25% (2/8) developed end-stage renal disease, including the one patient who had received postoperative hemodialysis. Recurrences occurred in five of seven patients with adequate oncological surveillance. Recurrences were successfully treated endoscopically in 80% (4/5) patients, and one patient had metastases. Of the eight patients, four have died. Death occurred 4 months, 1 year, 1.2 years and 3.5 years after partial nephrectomy. Of these patients, one succumbed to metastatic disease; the exact cause of death is unknown in the other three, but there was no documentation of metastatic cancer. The mean duration of follow up in the remaining four patients, all without evidence of metastatic urothelial cancer, is 71 months (range 22-108 months). In summary, partial nephrectomy for upper tract urothelial carcinoma in patients with imperative indications averts end-stage renal disease in most patients, and appears to be associated with acceptable disease-specific survival. Partial nephrectomy is a sparingly used option in patients with upper tract urothelial carcinoma refractory to endoscopic management who have imperative indications for nephron sparing.International Journal of Urology 10/2013; 21(4).
