In 207 men with symptomatic benign prostatic hyperplasia the international prostate symptom score and score on quality of life were collected. Cystometric tests with pressure-flow studies were performed in these patients with special attention to the assessment of obstruction grade. Of the men 24% appeared not to have obstruction. A significant correlation was found between size of the prostate and grade of obstruction. No correlation was found between obstruction grade, and any symptom score or quality of life score, while symptom score and quality of life correlated well. In 41 patients the outcome of laser prostatectomy was evaluated 6 months after the procedure. Mean symptom score decreased from 19.1 to 5.4 and mean quality of life score decreased from 3.7 to 1.3 in the 31 obstruction patients, compared to decreases of 19.6 to 10.1 and 3.6 to 2.6, respectively, in 10 without obstruction. The improvement in the obstruction patients was significantly better but nonobstruction patients will benefit from prostatectomy as well.
