title: Transurethral evaporation of the prostate for treatment of benign prostatic hyperplasia: results in 168 patients with up to 12 months of followup.
abstract: OBJECTIVE
  We assessed the safety and efficacy of transurethral evaporation of the prostate for the treatment of symptomatic benign prostatic hyperplasia (BPH).
  
  
  METHODS
  A total of 168 patients with symptomatic BPH underwent transurethral evaporation of the prostate. Peak flow rate, American Urological Association symptom index and post-void residual were assessed at baseline, and at 3, 6 and 12 months of followup.
  
  
  RESULTS
  We found a statistically significant decrease in mean American Urological Association symptom index from 20.6 at baseline to 7.2 at 12 months (mean difference 13.4, 65% reduction, p < 0.0001). We also found a statistically significant improvement in mean peak flow rate from 8.2 to 18.2 cc per second, respectively (mean difference 10, 122% increase, p < 0.0001). The most frequent complications were irritative voiding symptoms in 22.6% of patients and urinary tract infections in 4.8%. There were no additional major complications.
  
  
  CONCLUSIONS
  From these results transurethral evaporation of the prostate appears to be safe and effective for treatment of BPH at 12 months of followup.
