PURPOSE: The development of minimally-invasive approaches to donor nephrectomy (DN) has been primarily driven by the potential advantages it presents the donor. Questions remain over the long-term outcomes of these newer techniques compared to traditional open DN.

METHODS: All donor and recipient records of DN performed between 1963 and 2014 were reviewed. Donor and recipient demographics, intraoperative parameters, complications, and short- and long-term outcomes were analyzed.

RESULTS: Between 1963 and 2014, we performed 4,296 DN: 2,638 open (ODN), 1,183 hand-assist laparoscopic DN (HA-LDN), 200 pure LDN (P-LDN), and 94 robotic-assist LDN (RA-LDN). Compared to ODN, LDN makes donation more accessible to an older and heavier (p<0.001) population. LDN has a higher probability of procuring the left kidney (p<0.001). All 3 modalities of LDN were found to require a longer operative time (p<0.001), with RA-LDN taking significantly longer than HA-LDN or P-LDN (p<0.001). LDN decreased the need for intraoperative blood transfusion (p<0.001), and reduced intraoperative complications (p<0.001) and hospital length of stay (p<0.001). However, short-term (p<0.001) and long-term (p<0.001) readmissions were significantly greater with LDN compared to ODN. HA-LDN was an independent risk factor for incisional hernia over all other modalities (p<0.001). Recipient delayed-graft was unaffected by surgical technique and 1-year graft failure seemed to be lower with LDN (p<0.001).

CONCLUSION: LDN has made kidney donation more accessible to a greater number of patients while decreasing intraoperative complications and hospital length of stay. These improvements in technique may be offset by a higher readmission rate and long-term complications.
