title: Access techniques, platforms and instruments for LESS.
abstract: OBJECTIVE
  To summarize the available tools available for performing LaparoEndoscopic Single-Site surgery in Urology.
  
  
  METHODS
  A comprehensive electronic literature search was conducted in May 2011 using the Medline database to identify all publications relating to  NOTES and LESS in urology and information on devices were also obtained by accessing company Websites.
  
  
  RESULTS
  Multiple access ports are available and allow to insert several instruments through multiple channels inside a larger single port. Due  to lack of triangulation intracorporally, companies developed various articulating and bent instruments, limiting clashing and allowing increased  working space. The ideal endoscope for LESS should remove the light cord and camera head from the operative field. Articulating and low profile scopes are now available. Furthermore, surgeons can use extra-long scopes.
  
  
  CONCLUSIONS
  Various tools currently are available for single-site surgery. Randomized studies are needed to determine the Platform selection.
