OBJECTIVE: To compare long-term functional outcomes and pain scale scores of patients who underwent laparoendoscopic single-site (LESS)- robot-assisted partial nephrectomy (RAPN) to those who underwent conventional RAPN (C-RAPN), as LESS surgery is increasingly being adopted by urologists worldwide to reduce morbidities and scarring associated with surgical interventions. PATIENTS AND METHODS: In all, 167 consecutive patients who had RAPN were identified from our Institutional Review Board-approved computerised database between October 2006 to July 2012. Patients were stratified into two groups: 80 patients who underwent C-RAPN and 79 who underwent LESS-RAPN. RESULTS: The LESS-RAPN group had a longer warm ischaemia time [WIT, mean (sd) 26.5 (10.5) vs 19.8 (13.1) min; P = 0.001] and total operation time [TOT, mean (sd) 210.3 (83.4) vs 183.1 (76.1) min; P = 0.033] when compared with the C-RAPN group. While, the LESS-RAPN group and C-RAPN group were not significantly different for the number of patients with negative surgical margins [77 (96.2%) vs 73 (91.4%); P = 0.194), absolute change in postoperative renal function [mean (sd) -6.5 (16.7)% vs -7.6 (16.7)%; P = 0.738) and postoperative complications rate [12 (15.0%) vs 10 (12.6%); P = 0.279). Furthermore, the LESS-RAPN group had lower visual analogue pain scale (VAPS) scores at discharge [mean (sd) 2.1 (1.3) vs 1.7 (1.0); P = 0.048]. CONCLUSIONS: Despite a significantly longer WIT and TOT, the functional outcomes of LESS-RAPN were comparable to those of C-RAPN for tumours of similar mean sizes and complexities, without any detriments in oncological and complications outcomes. On discharge, patients who underwent LESS-RAPN also reported lower pain levels as one of the advantages of minimally invasive surgery. With the development of instrumentation specifically designed for single-site surgery, LESS could be more easily conducted in patients who are interested in improved quality of life outcomes.
