 note = {Laparoscopic living donor nephrectomy（LDN）has become a standard procedure, and transperitoneal LDN is now performed at many centers. Since 2001, we have been developing a retroperitoneoscopic living donor nephrectomy（RPLDN）technique that allows LDN to be performed by a direct retroperitoneal approach that does not interfere with the abdominal organs. In this study, we examined the operating time, blood loss, total and warm ischemic times（TIT, WIT）, length of stay, number and length of renal arteries and vessels, graft function, and complications in 54 kidney donors（19 men, 35 women；mean age 57.1±11.8 years）who underwent living donor kidney transplantation with allografts obtained by RPLDN. Mean follow-up was 16.8 months. Donor nephrectomy was successful in all patients. Fifteen kidneys had ≥ 2 renal arteries. The complication rate was 5.6％. There were no serious complications. Ureteral complications occurred in four recipients, who were successfully treated by retrograde ureteral stent placement. Mean TIT was 87.7 min and mean WIT was 4.7 min. Mean serum creatinine levels in recipients were 3.5, l.5, and 1.4 mg/dL on postoperative days 1, 7, and 14, respectively. Slow graft function was noted in four cases（7.4％）, which normalized within 2 weeks of surgery. One-year donor survival was 100％ and 1-year graft survival was 98.1％. All RPLDNs were well tolerated and the impact on recipient graft function was excellent. RPLDN could be an option for LDN.},
