title: [First 25 cases of photo-selective vaporization of the prostate (PVP) with 120-watt high performance system for benign prostatic hyperplasia].
abstract: OBJECTIVE
  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).
  
  
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  PVP using a 120-W HPS was shown to be an effective, safe procedure for patients with BPH and lower urinary tract symptoms.
