Abstract:Objective:To present clinical experience of retroperitoneal laparoendoscopic single-site (LESS) upper urinary tract radical surgery using self-made single-port device.Methods:Between July 2010 and July 2011, a total of 12 patients underwent retroperitoneal LESS upper urinary tract radical surgery by one experienced surgeon, including 5 radical nephrectomy and 7 nephroureterectomy. All procedures were carried with retroperitoneum through an incision 3 cm above the iliac crest. After extending the retroperitoneum with a ballonet, a self-made single-port device was placed and surgery procedures were performed with flexible and standard laparoscopic instruments. All specimens were extracted through the extended incisions or a separated incision.Results:All procedures were completed successfully, with no conversion to standard multiport laparoscopic or open surgery. The mean laparoscopic operation time was 94(60-191)mins, and the mean estimated blood loss (EBL) was 83(0-400)ml. Postoperative hospital stay was 7(5-10) days. One patient (8.3%) was noted to have urinary tract infection post-operatively.Conclusions:For properly selected patients, the retroperitoneal LESS radical nephrectomy and nephroureterectomy is safe and feasible,but observation for long-term outcome as well as improvements of the instruments and surgical technique are needed.
