Abstract：Objective:To investigate the clinical safety and feasibility of robotic transumbilical laparoendoscopic single-site renal cyst decortication.Methods:From December 2013 to January 2014 ,3 cases of robotic transumbilical laparoendoscopic single-site renal cyst decortication were perfor med in our depart ment .The patient was placed in a 45°flankpositionfortransperitonealsurgery.A2-cmskinincisionaroundtheumbilicus was madeanddeepenedto the anterior rectus fascia ,then the peritoneum was incised and the Port was deployed .A8 .5-mmvideo-laparoscope , two 5-mmtrocars and a 5-mm assisted trocar were inserted through the Port syste m.Diagnostic laparoscopy was perfor med before robotic checking .The operative robot then was brought in over the patient'healthy side .Standard procedureoflaparoscopicrenalcystdecorticationwasperformed.Thespecimens wereremovedthroughtheumbilical incision.Results:Three cases of robotic transumbilical laparoendoscopic single-site renal cyst decortication were per-for med successfully with no conversion to open or 3-port laparoscopic approach .The operative ti me was 75 ,65 and 50 min,theestimatedbloodloss was20,15and10 mL,andthepostoperativehospitalstaywas2,3and3days,re-spectively.Nointro-operative complication was observed.There was no postoperative complications during a short follow-up period .Conclusions:Initial experience on robotic transumbilical laparoendoscopic single-site renal cyst decorticationhadshownitsclinicalsafetyandfeasibility.However,thoseresultsshouldbefurtherprovedbylarge sample,multiplecenters,randomcontrol studyandlong-termfollow-up.
