Techniques of Vascular Control in Laparoscopic Donor Nephrectomy

Objectives: Laparoscopic donor nephrectomy has become the method of choice for removal of living donor kidneys. The ENDO GIA stapler is commonly used for division of the renal vessels, but it can lead to some loss of graft vascular length. Besides, stapler malfunction can occur. In this study, we report our experience using polymer locking clips for vascular control, compared with previous experience using the ENDO GIA stapler. Materials and Methods: Eleven donors underwent laparoscopic donor nephrectomy from November 2005 to September 2007. Both renal artery and vein were divided after 2 or more polymer locking clips had been applied on the donor side. The operative times, warm ischemia times, graft function, and vascular complications were compared with the previous 33 donors using the ENDO GIA stapler for renal vein control. Results: The operative and warm ischemia times were similar. With the polymer locking clip technique, we harvested nearly the entire renal vein length. There were no vascular complications or graft loss with the use of polymer locking clips. In our series, malfunction of the ENDO GIA stapler device occurred in 1 patient requiring the surgery to be converted to an open procedure. Both donor and recipient outcomes were similar no matter whether polymer locking clips or the ENDO GIA stapler was used for vascular control during the laparoscopic donor nephrectomy. Conclusion: In our series, there were no vascular complications and no device failure during vascular control using polymer locking clips. We believe that polymer locking clips are safe, yielding greater vessel length during laparoscopic donor nephrectomy.
