| Laparoendoscopic single-site surgery (LESS) probably represents the next evolutionary step in laparoscopic surgery. Although most urologic procedures are feasible by the LESS approach, significant challenges in terms of intraoperative ergonomics and requirement for laparoscopic skill are present. New, specially designed instruments and ports represent a solution for combating ergonomic problems during surgery. Documentation of the advantages of LESS over other approaches is currently lacking, as comparative clinical trials are scarce in the literature; in the absence of such information, the technique has been accepted at centers of laparoscopic expertise. Thus, further prospective randomized clinical trials are necessary to fully characterize the outcomes of LESS.
