RESUMEN
BACKGROUND The aim of this study was to compare and evaluate surgical techniques used for living donor nephrectomy (LDN). MATERIAL AND METHODS We performed a meta-analysis to compare 4 surgical techniques: open LDN (OLDN), laparoscopic LDN (LLDN), hand-assisted LLDN (HALLDN), and robot-assisted LLDN (RLDN). RESULTS No significant differences were found among these surgical techniques in terms of BMI, donor postoperative complications, 1-year graft survival, and DGF. Compared to the OLDN, the other 3 surgical techniques preferred to harvest the left kidney. When the right kidney was chosen as a donor, OLDN was the first-choice surgical technique. EBL was significantly lower in the HALLDN, LLDN, and RLDN groups when compared to the OLDN group. However, operative time and WIT were significantly shorter in the OLDN group. The RLDN group had an increased rate of donor intraoperative complications and a significantly lower VAS on day 1. The OLDN group required more morphine intake than the LLDN group. The length of hospital stay was significantly longer and AR was significantly higher in the OLDN group than in the LLDN and HALLDN groups. CONCLUSIONS There are no significant differences in donor postoperative complications, recipient DGF, and graft survival among the 4 surgical techniques. OLDN reduces WIT and operation time, but increases EBL and AR. RLDN and LLDN reduce the length of hospital stay, morphine intake, and VAS, and thus accelerate recovery. However, RLDN is associated with increased intraoperative complications.
