title: Laparoendoscopic single site surgery in urology: A single centre experience.
abstract: OBJECTIVE
  To analyze our experience of 87 cases with single port surgery, which is also known as laparoendoscopic single site surgery (LESS).
  
  
  METHODS
  Case records of all LESS procedures performed between December 2007 and June 2010 were analysed. The procedures performed were donor nephrectomy (n=45), simple nephrectomy (n=27), radical nephrectomy (n=5), pyeloplasty (n=9), and ureteroneocystostomy (n=1). Parameters analysed were operating room (OR) time, estimated blood loss (EBL), visual analogue score (VAS), and complications in all patients undergoing LESS procedure and additionally, warm ischaemia time (WIT) and graft outcome in patients undergoing LESS donor nephrectomy. In reconstructive procedures, the functional assessment was performed with a diuretic renogram at 6 months.
  
  
  RESULTS
  In LESS donor nephrectomy, the mean WIT was 6.9 ± 1.9 min. Mean serum creatinine in recipients at 1 month was 0.96 ± 0.21 mg%. We encountered one instance each of renal artery injury, renal vein injury, large bowel injury, minor cortical laceration at the upper pole and two instances of diaphragmatic injury. In LESS simple nephrectomy, the average OR time was 148.7 ± 52.2 min and hospital stay was 3.7 ± 1.2 days. There was one instance of large bowel injury during specimen retrieval. In LESS radical nephrectomy, the average OR time was 202.5 ± 35.7 min and average hospital stay was 4.2 ± 1.3 days. 6 patients of LESS pyeloplasty completed follow up with a diuretic renogram showing a good drainage. LESS ureteroneocystostomy could also be performed successfully without any complications.
  
  
  CONCLUSIONS
  LESS surgery can be accomplished safely in nephrectomy and reconstructive procedures such as pyeloplasty and ureteroneocystostomy with equivalent outcomes as standard laparoscopy and with added benefits of cosmesis and quicker convalescence. LESS donor nephrectomy is a technically feasible procedure; current status of procedure needs to be proved with randomised controlled studies.
