[Further studies on the relationship between benign prostatic hyperplasia and prostatitis].

Benign prostatic hyperplasia(BPH) and prostatitis are two common diseases in aging men. In recent years, the study of correlation between these two diseases has been paid more and more attention to. Some researchers presumed that inflammation is one of the most important causations of BPH, however, it is not profound enough on this etiologic hypothesis at present. The writer, on the base of his clinical experiences, dissertated the etiology of BPH, the pathologic figures of coexistence of BPH and prostatitis, and the presumption of inflammation promoting BPH on the molecular biology level. We hope our colleagues pay attention to this problem, and do more study on it.
