AIM: To systematically review the literature regarding clinical outcomes of 180W XPS GreenLight laser (GL) vaporization for the treatment of lower urinary tract symptoms (LUTS) related to benign prostatic hyperplasia (BPH).
METHODS: Recent publications in the field of 180 Watt GreenLight Laser (GL) vaporization for the treatment of LUTS due to BPH were identified by a literature search. It was searched for peer reviewed original articles in 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. 30 papers published between 2012 and 2014 matched this search. Out of this collective 10 papers were identified dealing with consecutive cohorts of patients treated with the 180W XPS GreenLight® laser.
RESULTS: Ten papers included a total experience of 1640 patients. The only RCT in this field compares 180W XPS with transurethral resection of the Prostate (TURP). Functional outcomes and prostate volume reduction following GL vaporization were similar to TURP. Catheterization time and hospital stay were shorter in patients undergoing 180W XPS GL-vaporization (41 and 66 hours vs 60 and 97 hours respectively). Four papers compared the 180W XPS system to former GL devices demonstrating 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.
CONCLUSION: The 180W XPS GreenLight laser offers shorter operation times than the 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.
