RESUMO
ObjectiveTo summarize the initial experience of transumbilical laparoendoscopic single-site surgery of urology.MethodsFrom February 2010 to March 2011,21 patients underwent laparoendoscopic single-site surgery using transumbilical single-site and common surgical instruments of laparoendoscopic.Nine patients underwent single-site laparoscopic ureterolithotomy,5 underwent transumbilical single-site laparoscopic ureteral stricture resection and anastomosis,5 underwent transumbilical single-site laparoscopic renalcyst unroofing and 2 had a nephrectomy.All of the cases were definitely diagnosed.A single umbilical incision of 1.5 cm to 2.5 cm was made for Triport.The procedures were performed according to the methods used in classical laparoscope methods using general instruments.ResultsAll the operations were successfully completed without conversion to open surgery.The mean operative time of ureterolithotomy was 143 (120-230) min,the mean operative time of ureteral stricture resection and anastomosis was 157 (120 -180) min,the mean operative time of unroofing of renal cysts was 110 (95 -132) min,and the operative time of the nephrectomy was from 95 to 120 min.The intestinal tract function recovered within 1 -2 d,the drainage tube was removed within 2 -3 d and the postoperative hospitalization duration was 4 -7 d.The symptoms were reduced or disappeared and no major intraoperative or postoperative complications occurred within 4 - 6 months.Conclusions Transumbilical laparoendoscopic single-site surgery represents a safe and feasible operation for urologic patients.With more clinical practice,laparoendoscopic single-site surgery could be generally applied.
