title: Laparoendoscopic single-site surgery and cancer.
abstract: OBJECTIVE
  To perform a survey of the current state of laparoendoscopic single-site surgery (LESS) and its implementation in the treatment of malignant disease of the urinary tract. Although it is a recent development in the field of laparoscopic surgery with still unproven long-term results, LESS may prove to be more commonly performed in the coming years while managing urologic cancer patients.
  
  
  METHODS
  A PubMed search was conducted using the key words laparoendoscopic single-site surgery, LESS, urologic cancer. Relevant articles were reviewed for data on the management of urologic malignancy with LESS.
  
  
  RESULTS
  The first articles describing LESS for urologic cancers were published in 2007. Since then, published experience with this technique has increased. LESS has been implemented as an alternative to conventional laparoscopic surgery and open surgery for the treatment of major urologic cancers. The proposed advantages of LESS are the aesthetic benefit of a single incision and a quicker and less painful recovery. Disadvantages are the lack of instrument triangulation, instrument clashing and the steeper learning curve. As this is a fairly recent technical innovation, long-term functional and oncological results for LESS have not yet been published.
  
  
  CONCLUSIONS
  LESS is a novel technical advance over conventional laparoscopic surgery, and it can be successfully used in the treatment of patients with urologic cancers. Published data support the feasibility and safety of LESS interventions for major urologic cancers, and newer data may assist in finding LESS's ultimate position among therapeutic options for patients with urologic malignancies.
