OBJECTIVE: To evaluate the outcome in @entity1 undergoing photoselective vaporization of the prostate for @entity1069 as part of the Clinical Research Office of the Endourological Society Global GreenLight Laser Study. METHODS: Data were collected on 713 @entity1 with lower urinary tract symptoms suggestive of @entity1069 undergoing photoselective vaporization of the prostate at 25 centers worldwide, between April 2010 and April 2012. Three types of GreenLight laser powers were used: 80  W, 120  W or 180  W. Intraoperative and @entity260 were recorded. Outcome parameters measured at baseline, 6-12  weeks, 6  months and 12  months were: uroflow measurements, International Prostate Symptom Score; @entity1486 and International Index of Erectile Function. RESULTS: Operating time was shortest with the 180-W laser at 53.8  min. Intraoperatively, @entity548 occurred in 3.1% of @entity1 . Statistically significant changes were reported in maximum flow rate, postvoid residual urine, International Prostate Symptom Score, quality of life score and @entity1486 (P  <  0.01) at each time-point assessed for the 80- and 120-W lasers as well as for the 180-W laser, with the exception of @entity1486 at 6  months and 12  months. There were 14 Clavien-Dindo grade  III-A complications and two grade  III-B. The @entity322 rate at 12  months was 6.3%, 4.5%, and 2.6% for the 80, 120 and 180  W lasers, respectively. The overall blood transfusion rate was 0.4%. CONCLUSIONS: Objective and subjective improvement after GreenLight laser treatment worldwide was significant at 1-year follow up. Morbidity and complications were low. Although not a randomized control study, the data can provide an indication of the outcome of the different GreenLight laser powers.
