Techniques and Training with GreenLight HPS 120-W Laser Therapy of the Prostate: Position Paper

We report the technical recommendations of the International GreenLight User Group on photoselective vaporization of the prostate in men with benign prostatic hyperplasia using the GreenLight HPS system (American Medical Systems, Minnetonka, Minnesota, USA). This high-power system employs a 120-W laser, which is a modification of the previous 80-W potassium-titanyl-phosphate (KTP) laser. The objective of this report is to optimize the efficacy and safety of the procedure by drawing on the experience of this multicentre international group. In this regard, recommendations for training are made, which relate to existing users of the 80-W KTP laser as well as to new laser users.
