Arterial blood flow in the prostate in the syndrome of chronic pelvic pain/chronic prostatitis

Resumo

Causes and mechanisms of chronic pelvic pain/chronic prostatitis (CPP/CP) syndrome are not well investigated yet. It is suggested that pain in an inflammatory form of this syndrome may be due to tissue inflammation. In the non-inflammatory form pain may result from neurogenic factors. Standard diagnostic methods in the absence of inflammation often fail to detect pathological changes in the prostate. We made duplex mapping of the prostate and obtained quantitative characteristics of arterial hemodynamics of the prostate. Control values of arterial prostatic blood flow were developed after examination of healthy volunteers. These values were compared with similar values of arterial blood flow in CPP/CP syndrome. We found a significant decrease of the peak systolic velocity in patients with non-inflammatory CPP/CP syndrome. There is a direct correlation between intensity of pain syndrome and peak systolic velocity of arterial blood flow. Thus, pain may arise from chronic prostatic ischemia.
