title: A randomized controlled trial comparing transurethral resection of the prostate, contact laser prostatectomy and electrovaporization in men with benign prostatic hyperplasia: analysis of subjective changes, morbidity and mortality.
abstract: OBJECTIVE
  We analyze subjective changes, morbidity and mortality in men with lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH) after transurethral resection of the prostate, contact laser prostatectomy and electrovaporization.
  
  
  METHODS
  A prospective, randomized controlled trial was conducted on men with lower urinary tract symptoms, who met the criteria of the International Scientific Committee on BPH, had a prostate volume between 20 and 65 ml., and had Schäfer's obstruction grade 2 or greater. Objective morbidity was recorded for up to 12 months. Subjective morbidity was measured by a questionnaire completed by patients. Subjective changes were quantified using the International Prostate Symptom Score, Symptom Problem Index, Quality of Life question and BPH Impact Index. These indexes and the morbidity questionnaire were measured weekly for the first 6 weeks postoperatively and then at 3, 6 and 12 months.
  
  
  RESULTS
  Transurethral prostatic resection was analyzed in 50 men, laser treatment in 45 and electrovaporization in 46. Baseline characteristics, and changes in the symptom scores up to 12 months postoperatively were similar. Perioperative blood loss and perforation were greatest in the resection group, and retention was greatest in the laser group. During the first 6 postoperative weeks there was less pain and less hematuria after resection, and less incontinence after laser prostatectomy.
  
  
  CONCLUSIONS
  Subjective changes are similar for transurethral prostatic resection, contact laser and electrovaporization. In the first 6 weeks after treatment there are only slight differences in pain, hematuria and incontinence among the therapies.
