Vaporization techniques for benign prostatic obstruction: GreenLight all the way?

PURPOSE OF REVIEWTo give an overview and discuss the recent literature of different vaporization techniques of the prostate using laser energy or high-frequency current. RECENT FINDINGSTen studies covering GreenLight vaporization of the prostate with its evolution from 80 W KTP to 120 W HPS to 180 W XPS system were identified. Only one study had a randomized design comparing HPS to transurethral resection of the prostate. The diode laser is discussed with its results after recent modification with quartz head fiber. Although complication rates are low, the comparison to transurethral resection of the prostate is lacking. Current data on established vapoenucleation and promising vaporesection of thulium:YAG lasers are presented. Further, recent studies on plasmakinetic vaporization are discussed. SUMMARYAt present, high evidence data on vaporization techniques of the prostate are lacking. The data on GreenLight vaporization of the prostate are the most convincing.
