Current status of natural orifice trans-endoscopic surgery (NOTES) and laparoendoscopic single site surgery (LESS) in urologic surgery

laparoendoscopic single site surgery (less) and natural orifice transluminal endoscopic surgery (notes) represent novel approaches in urological surgery. to perform a review of the literature in order describe the current status of less and notes in urology. references for this manuscript were obtained by performing a review of the available literature in pubmed from 01-01-02 to 15-05-09. search terms included single port, single site, notes, less and single incision. a total of 412 manuscripts were initially identified. out of these, 64 manuscripts were selected based in their urological content. the manuscript features subheadings for experimental and clinical studies, as notes-less is a new surgical technique and its future evolution will probably rely in initial verified feasibility. a subheading for reviews presents information regarding common language and consensus for the techniques. the issue of complications published in clinical series and the future needs of notes-less, are also presented.
