First 25 cases of photo-selective vaporization of the prostate (PVP) with 120-watt high performance system for benign prostatic hyperplasia

Abstract

(Purpose): We examined the safety and efficacy of photo-selective vaporization of the prostate (PVP) using a 120-W high-performance system (HPS) for benign prostatic hyperplasia (BPH). (Patients and methods): We prospectively reviewed the records of 25 patients who had undergone PVP using a 120-W HPS in our institution. Patients were evaluated pre-operatively, and at 2 weeks and 1, 3, and 6 months postoperatively. (Result): The mean age was 73.6 years, and the mean estimated preoperative prostate volume was 51.5 ml. Laser vaporization was performed successfully in all 25 patients. The operating time was 104 ± 29 minutes. The mean decrease in hemoglobin was 0.6 g/dl on post-operative day 1. The International Prostate Symptom Score (IPSS), QOL score, maximum flow rate, and residual urine volume were significantly improved 2 weeks after the procedure. There were no serious complications during the peri-operative period, and no patients were transfused. (Conclusion): PVP using a 120-W HPS was shown to be an effective, safe procedure for patients with BPH and lower urinary tract symptoms. © 2013 The Japanese Urological Association.
