Pure laparoscopic donor nephrectomy: 3-year experience and analysis of a refined technique to maximize graft function.

ABSTRACT

PURPOSE: Strategies for vascular control and limiting warm ischemia time (WIT) vary between institutions for laparoscopic live donor nephrectomy (LLDN). We refined our technique and retrospectively determined whether it safely provides an allograft of comparable quality to published series. PATIENTS AND METHODS: Fifty consecutive LLDN between February 2003 and November 2006 were reviewed. Key technical aspects include placing the perfused kidney and transected ureter entirely within an endocatch bag, with the string externalized through an extended lateral port site incision. Vessels are then controlled with clips, or a Satinsky clamp for right sided veins. The extraction incision is completed and the bag immediately withdrawn and placed on ice. WIT ends with perfusion with cold UW solution. RESULTS: The series includes 42 left and 8 right kidneys. 13/50 (26%) demonstrated anatomical complexity (more than one artery, vein and/or ureter). Average operative time was 178 minutes. Average WIT was 128 seconds. Conversion to open surgery occurred in two patients, one to define challenging anatomy, and another for hemorrhage from the renal artery stump. Average blood loss was 76 ml. Average length of stay was 3.6 days. Average recipient creatinine was 1.26 mg/dl at discharge. Delayed graft function occurred in three recipients. ATN/slow normalization of creatinine occurred in four. Graft survival at one year was 96%. CONCLUSIONS: The refined technique of LLDN mimics important principles of open donor nephrectomy. Controllable variables which may impact graft function are optimized. WIT is amongst the lowest reported for pure laparoscopy, without increasing complication rates, blood loss, or operative time.
