Introduction: This general article summarizes contemporary clinical opportunities of GreenLight (GL) laser in the treatment of benign

prostatic hyperplasia (BPH) and evaluates possible experimental using of the laser in partial nephrectomy. Our article is based on literature

data and paricularly on clinical and experimental work of authors. Technical data: Characteristics of GL are caused by its wavelenght

(532 nm) and power. Previous laser beam emited by 80 Watts (W) device on potassuim-titanyl-phosphate (KTP) crystal base was

recently replaced by 120 W device (HPS, high performance system) on lithium borate (LBO) crystal base. GL is nowadays the most applied

laser technology in the treatment of BPH, so-called photoselective evaporization of the prostate. Nevertheless transurethral resection

of the prostate (TUR-P) is still the gold standard of the treatment of BPH.

Conclusion: GL has a routine usage in the treatment of BPH, the

advantage of PVP compared with TUR-P is a minimalization of bleeding and TUR- syndrome, very short time or no time of leaving of the

permanent catheter and shorter hospitalization time. GL is an experimental method in other indications (kidney resection, stricture of

urethra, urinary bladder tumour) for the present.

Keywords: benign prostatic hyperplasia, laser, photoselective evaporization of the prostate, transurethral resection of the prostate, partial nephrectomy.
