Novel technique for hand assisted laparoscopic right donor nephrectomy

PURPOSE: Most surgeons divide the renal vein with a laparoscopic stapler during laparoscopic donor nephrectomy. The right renal vein is usually shorter than the left one and using the stapler on the right side can result in a higher incidence of vascular complications for right kidney recipients. We present our experience with a new technique for hand assisted laparoscopic right donor nephrectomy. MATERIALS AND METHODS: We designed a new vascular clamp to be completely inserted into the peritoneal cavity through the hand port incision in hand assisted laparoscopy. The renal vein with a cuff of the inferior vena cava was then excised. The defect in the inferior vena cava was sutured intracorporeally. RESULTS: A total of 80 kidney donors underwent hand assisted laparoscopic right donor nephrectomy using the new technique. Mean +/- SD operative time was 184 +/- 36 minutes. Operative time was decreased in the last 30 patients to 152 +/- 22 minutes. Intracorporeal suture time on the inferior vena cava was 16 +/- 3 minutes. No intraoperative complications were noted and there was no partial or total graft loss. Mean blood loss was 50 +/- 35 cc. Mean warm ischemia time was 4 +/- 2 minutes. Hospital discharge was on postoperative day 1 or 2 in 81% of patients. Graft function was normal in 78 recipients with a day 5 postoperative serum creatinine of 1.6 +/- 0.9 mg/dl. Two recipients showed delayed graft function and were treated medically. CONCLUSIONS: This technique for hand assisted laparoscopic right donor nephrectomy has proved to be safe and reproducible. We recommend practicing laparoscopic inferior vena cava suturing in the animal laboratory before performing it in humans.
