title: Clinical outcome at 3 months after transurethral vaporization of prostate for benign prostatic hyperplasia.
abstract: OBJECTIVE
  To evaluate the clinical outcome of transurethral vaporization of the prostate (TUVP) for the management of benign prostatic hyperplasia (BPH).
  
  
  METHODS
  Between March and June 1995, 30 patients with symptomatic BPH treated by TUVP were enrolled in this study. Transrectal ultrasonography (TRUS) was done preoperatively. American Urological Association (AUA) symptom score determination, pressure flow study, and questionnaire (for evaluating potency) were done preoperatively and 3 months postoperatively.
  
  
  RESULTS
  The average age was 70.5 years (range 60 to 83) and estimated prostate size by TRUS before surgery was 33.8 +/- 14.0 g. The average AUA symptom score decreased significantly 3 months after TUVP (6.2 +/- 7.8 versus 18.2 +/- 9.0; P < 0.01). The maximum urine flow rate (Qmax) was 11.1 +/- 3.7 mL/min before TUVP (mean +/- SD) and 17.0 +/- 6.5 mL/min 3 months after TUVP, whereas the detrusor pressure at maximum urine flow (Pdes at Qmax) was 61.0 +/- 23.9 and 41.2 +/- 15.2 cm H2O, respectively. Qmax increased and Pdes at Qmax decreased significantly 3 months after TUVP. Of the 30 patients, 3 (10%) developed bladder neck contracture. Of the 24 patients who were potent sexually before operation, 3 (12.5%) developed impotence 3 months after surgery.
  
  
  CONCLUSIONS
  TUVP is an effective alternative surgical procedure to relieve obstruction for patients with symptomatic BPH. However, cautious attitude on its usage is advocated based on our preliminary results indicating the occurrence of late complication such as impotence and bladder neck contracture.
