title: A systematic review of experience of 180-W XPS GreenLight laser vaporisation of the prostate in 1640 men.
abstract: OBJECTIVE
  To systematically review the literature regarding clinical outcomes of 180-W XPS GreenLight laser (GL) vaporisation for the treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH).
  
  
  METHODS
  Recent publications were identified in the field of 180-W GL vaporisation for the treatment of LUTS due to BPH. We searched for peer-reviewed original articles in the English language. Search items were: '180W lithium triborate laser' or '180W greenlight laser' or '180 watt lithium triborate laser' or '180 watt greenlight laser' or 'XPS greenlight laser'. In all, 30 papers published between 2012 and 2014 matched this search. Of these, 10 papers were identified dealing with consecutive cohorts of patients treated with the 180-W XPS GL RESULTS: The 10 papers included a total experience of 1640 patients. The only randomised controlled trial in this field compares 180-W with transurethral resection of the prostate (TURP). Functional outcomes and prostate volume reduction after GL vaporisation were similar to TURP. Catheterisation time and hospital stay were shorter in patients undergoing 180W XPS GL vaporisation (41 and 66 h vs 60 and 97 h, respectively). Four papers compared the 180-W XPS system to former GL devices showing increased operation time efficiency and comparable postoperative voiding results and adverse events. One paper defined the learning curve to achieve an expert level according to the speed of the procedure and the effectiveness of volume reduction was met after 120 procedures.
  
  
  CONCLUSIONS
  The 180-W XPS GL offers shorter operation times than former devices. In the one randomised controlled trial comparison with TURP, volume reduction and functional results were comparable to those of TURP. Longer term studies are required.
