Brief summary

This is a Phase 4, prospective, open-label, randomized study of Greenlight XPS Laser versus BiVAP Saline Vaporization of the prostate in men with symptomatic Benign Prostatic Hyperplasia (BPH). The study consists of a screening phase, treatment, followed by follow-up visits at 1 week, 4 weeks, 3 months, 6 months, and 12 months.
