Outcome of laparoscopic living donor nephrectomy: Current status and trends in Japan

Laparoscopic nephrectomy (LN) has been accepted for donors in living donor kidney transplantation. But the current status of LN in living donors is not clarified yet in Japan. In this study, we surveyed 124 Japanese kidney transplantation centers to investigate the outcomes of living donor LN in 2006. Of 124 centers, 100 responded, and 52 performed LN. These centers performed 831 living donor nephrectomies, including 589 LN, and 242 open procedures. In 52 centers, 20 were performed as hand-assisted (HA) LNs, 23 non-HA (pure laparoscopic), five both HA and non-HA, and four laparoscope-assisted. Eighteen centers used a peritoneal approach, 31 used a retroperitoneal approach and three, both. Among 589 LN donors, three experienced life-threatening complications of bleedings and intestinal injury, but all of them survived. Blood transfusions were performed in nine donors (1.5%), and open conversions of LN in 33 (5.6%). Minor complications not requiring a long hospital stay were reported in 45. The mortality of LN was 0. Among the 589 recipients, there was one case of primary nonfunction after venous injury at the operation. Twenty eight recipients (4.8%) needed hemodialysis after transplantation because of delayed graft function. Urinary tract complications were noted in 11 recipients (2.5%). This survey presented the current status of LN in Japan.
