Lower urinary tract symptoms, pain and quality of life assessment in chronic non-bacterial prostatitis patients treated with alpha-blocking agent doxazosin; versus placebo.

Abstract

The efficacy of doxazosin monotherapy in chronic non-bacterial prostatitis was investigated in terms of urinary symptom, pain and quality of life assessment versus placebo. A total of 60 men with chronic non-bacterial prostatitis were randomised to daily supplement of 4 mg doxazosin or a placebo, for 3 months. International Prostate Symptom Score (IPSS) questionnaire was self administered at the entry and at 3 months after the cessation of the treatment. In addition, patients were asked to complete 2-item questionnaire on pain related symptoms of chronic prostatitis. Quality of life was assessed with a single item included in IPSS. Three months after cessation of the treatment there was a significant difference between the overall mean IPSS, pain and quality of life scores of the two groups in favour of alpha-blocking agent use (p = 0.001, p < 0.001 and p < 0.001, respectively). In patients undergone doxazosin treatment; symptom, pain and quality of life status revealed 32.94 +/- 5.27%, 36.57 +/- 5.67% and 36.78 +/- 4.75% overall improvement, respectively. IPSS appeared to be a valuable tool in assessing treatment outcome of chronic non-bacterial prostatitis.
