title: [Laparoendoscopic single-site surgery in urology using reusable systems].
abstract: OBJECTIVE
  Many disposable platforms have been available for laparoendoscopic single-site surgery (LESS) for a long time. Besides technical challenges cost remains the limiting factor for the widespread use of LESS. We present our experiences with the first completely reusable LESS platform.
  
  
  METHODS
  We performed LESS procedures in 52 patients, including nephrectomy (n=18), adrenalectomy (2), partial nephrectomy (3), pyeloplasty (4), renal cyst ablation (4), pelvic lymphadenectomy (15) and lymphocele ablation (6). All procedures were carried out using a novel reusable single-port device (X-ConeR, Karl-Storz) with a simplified combination of standard and preformed instruments. Perioperative and demographic data including a visual analogue pain scale (VAS) were obtained. Complications were recorded using the Clavien classification.
  
  
  RESULTS
  The mean age of the patients was 50.04 years. Conversion to standard laparoscopy was necessary in 3 cases and the additional use of a 3 mm needle instrument in 6 cases. There were no open conversions. Intraoperative and postoperative complications occurred in 3 (Clavien II in 2 and III in 1) cases. Mean operating time was 110, 90, and 89 min and hospital stay was 4.9, 3.1 and 3.6 days for nephrectomy, pelvic lymphadenectomy, and pyeloplasty, respectively. The mean VAS was 2.13, 1.07 and 1.5 while blood loss was 81.3 ml, 25.67 ml and 17.5 ml, respectively.
  
  
  CONCLUSIONS
  The LESS technique with a completely reusable platform is applicable to various indications in urology yielding favorable functional and cosmetic results. This novel simplified combination of instruments facilitates handling and shortens the learning curve. Reusable materials may help to reduce cost leading to a wider acceptance of LESS.
