GreenLight™ laser in the treatment of lower urinary tract symptoms due to benign prostatic enlargement.

For more than a decade, laser technology has facilitated a minimally invasive surgical method to treat patients with bladder outlet obstruction caused by benign prostatic hyperplasia. This article critically assesses the features of the GreenLight™ laser and its potential use in the treatment of lower urinary tract symptoms in benign prostatic hyperplasia patients. Recently, a significant body of evidence in the literature on good clinical outcomes in 1-year follow-up periods has been enriched with the findings from a few randomized trials, in which this device is compared with other minimally invasive or standard approaches. In turn, very few patients in the GreenLight laser study groups reach the end point of a 3- or 5-year follow-up time. However, most patients who underwent GreenLight laser treatment were treated successfully with a good clinical outcome and a minor rate of peri- and post-operative complications. Furthermore, it can be implemented in high-risk patients who are undergoing anticoagulation therapy. Bearing in mind the inherent characteristics of using a laser for treatment, one obvious consequence is that no pathological specimen remains for further study. This implies the necessity of suitable patient selection in whom the risk of prostate cancer should be minimal. In terms of cost-effectiveness, one should consider applying this method when dealing with patients who have a moderately enlarged prostate volume.
