To evaluate the efficacy and safety of photoselective vaporization of the prostate (PVP) for the treatment of benign prostatic hyperplasia (BPH),total 24 patients (mean age of 71.00±9.74 years) with BPH underwent PVP in our hospital by using Realton 100 W surgical green laser system. Prostate size,operation time,blood loss during operation,catheterization time and hospital stay were recorded. International prostate symptom score (I-PSS),maximum flow rate (Qmax),post void residual urine (PVR) were compared to the baseline. The results show that PVP is a safe and effective treatment for BPH,especially suitable for aged,high-risk or anticoagulant therapy patients. PVP has less bleeding during operation,shorter catheterization time and hospital stay．More follow-ups are needed to evaluate its long-term efficiency.
