Robotic laparoendoscopic single-site partial nephrectomy is increasingly carried out in an attempt to improve the cosmetic outcome of minimally-invasive procedures. However, the actual role of this novel technique remains to be determined. The present article reviews evidence and examines updates of robotic laparoendoscopic single-site partial nephrectomy outcomes reported in more contemporary studies. A comprehensive online systematic search of PubMed, Scopus and Web of Science databases according to Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria recommendations was carried out in January 2014, identifying data from 2008 to 2014 regarding robotic laparoendoscopic single-site partial nephrectomy. The majority of medical evidence to date is based on case reports or retrospective studies. Current studies show that robotic laparoendoscopic single-site partial nephrectomy is a feasible procedure carried out in an acceptable length of operative time, and resulting in a desirable cosmetic outcome and less postoperative pain. However, comparable studies show that robotic laparoendoscopic single-site partial nephrectomy is inferior to the conventional approach, especially with regard to warm ischemia time. Furthermore, the numerous limitations that exist with the utilization of the current commercial single-site devices make robotic laparoendoscopic single-site PN more challenging and more complicated for surgeons compared with conventional procedures. Further significant improvements, along with more studies, are required in order to develop the ideal robotic laparoendoscopic single-site robotic platform and overcome the current limitations. For the time being, robotic laparoendoscopic single-site partial nephrectomy procedures could be applicable in patients with low tumor size and complexity, and should not be routinely applied in all cases.
