GreenLight laser vapourization of the prostate is a safe and effective operation to treat difficulty with urination due to benign (non-cancerous) enlargement of the prostate, also known as benign prostatic hyperplasia (BPH) or benign prostatic enlargement (BPE). 

This is a minimally-invasive procedure where the enlarged prostate tissue is vapourized with a laser, without the need for any incisions.

Compared to traditional transurethral resection of the prostate (TURP), GreenLight laser vapourization of the prostate is associated with less bleeding and allows patients to return home the same day while providing equivalent success rates.
