RESUMO
<p><b>OBJECTIVE</b>To study the incidence of benign prostatic hyperplasia (BPH) complicated by chronic prostatitis.</p><p><b>METHODS</b>We performed routine examinations and bacterial culture of the expressed prostate secretion (EPS) for 213 cases of BPH, detected mycoplasma, chlamydia and serum PSA, and compared the results of IPSS of those complicated with chronic prostatitis before and after a 4-week anti-inflammatory treatment.</p><p><b>RESULTS</b>Of the total cases, 69 (32.4%) were complicated by chronic prostatitis, 27 (12.7%) EPS positive and 15 (7.0%) mycoplasma and chlamydia positive. Among the 69 cases of chronic prostatitis, 7 were found with an elevated level of PSA (> 4 microg/L), and 43 with the mean IPSS score decreased from (12.2 +/- 2.6) before anti-inflammatory treatment to (10.5 +/- 2.3) after it (P < 0.01).</p><p><b>CONCLUSION</b>EPS examination should be performed for patients with BPH, which is highly significant for the diagnosis of prostatitis, choice of medical or surgical treatment, improvement of therapeutic effect and reduction of complications.</p>
