[eng] Greenlight laser prostate vaporization is considered a valid alternative to transurethral prostate resection (TURP) for patient with LUTS due to BPH. The current review highlights the current evidence on greenlight technique and current state of-the-art. We will review clinically relevant concerns such as size limitation, economic issues and same-day surgery options. We will also describe technological improvements over time and its relationship with current vaporization practices. CURRENT SITUATION: Based on clinical trial Goliath, Greenlight 180W vaporization showed non-inferiority to TURP and similar mid-term functional outcomes. A benefit towards length of hospital stay, similar complication rate (below 80% at 2 years). The current laser generators (higher potency) are able to provide an ablative effect on tissue that is associated to a shorter operative time. The major advantage of greenlight laser is the same day discharge, with a low readmission rates. Greenlight laser is more cost-effective than TURP. CONCLUSIONS: Green light laser remains as an alternative valid option despite the technological improvements in the field.
