Abstract
Introduction:
Laparoscopic surgery has been a standard procedure of living donor nephrectomy (LDN). Transperitoneal hand-assisted laparoscopic LDN (HALDN) has been commonly reported by many centers with excellent outcome. However, there are few studies reporting retroperitoneoscopic LDN (RPLDN).
Materials and Methods:
Four hundred four consecutive kidney donors (124 men, 280 women) were enrolled in this study. Age of the donors was 55.0 ± 10.7 years. RPLDN was performed for 294 donors, and HALDN for 110 donors. We compared perioperative donor outcome and early complication rates between RPLDN and HALDN to evaluate the safety and efficacy of RPLDN.
Results:
Intraoperative blood loss was significantly less in RPLDN than in HALDN (p < 0.05). The conversion rate to open surgery was similar between the two groups. The intraoperative complication rate was 1.0% (two vascular injuries and one bowel injury) in RPLDN and 0.9% (one vascular injury) in HALDN. The postoperative complication rate was 3.4% (six surgical site infections, two postoperative bleeding, one colon perforation, one ileus, one rhabdomyolysis) in RPLDN and 1.8% (two surgical site infections) in HALDN. Although warm ischemic time was significantly longer in RPLDN than in HALDN (p < 0.01), the incidence of delayed graft function was similar between the two groups. Furthermore, there was no difference in 1-year graft survival between the two groups.
Conclusions:
Both RPLDN and HALDN procedures were well tolerated with minimal complication rates, and both procedures showed similar impact on recipient graft function. These results suggest that RPLDN could be a feasible option for LDN as well as HALDN.
