BACKGROUND:Laparoendoscopic single-site surgery (LESS) has gained popularity in urology over the last few years.OBJECTIVE:To report a stage 2a study of robot-assisted single-site (R-LESS) pyeloplasty for ureteropelvic junction obstruction (UPJO).DESIGN, SETTING, AND PARTICIPANTS:This study is an investigative pilot study of 30 consecutive cases of R-LESS pyeloplasty performed at two participating institutions between July 2011 and September 2013.SURGICAL PROCEDURE:Dismembered R-LESS pyeloplasty was performed at two surgical centers.MEASUREMENTS:Feasibility (conversion rate), safety (complication rate and Clavien-Dindo classification), efficacy (clinical outcome) of the procedure were assessed.RESULTS AND LIMITATIONS:The median patient age was 37 yr (range: 19-65 yr) and median body mass index was 23 kg/m(2) (range: 19-29 kg/m(2)). The median operative time was 160 min (range: 101-300 min), the median postoperative stay was 5 d (range: 3-13 d), and the median time to catheter removal was 3 d (range: 2-10). Two cases required conversion, the first one to standard laparoscopic technique and the second one to standard robotic technique. No intraoperative complications were reported. In three cases, an additional 5-mm trocar was needed. The postoperative complications rate was 26% (n=8).
