To evaluate the diagnostic value of color Doppler ultrasonography in prostastitis and benign prostatic hyperplasia (BPH0, we have analysed the patterns of color Doppler imagne(CDI), expressed prostatic secrotion (EPS) findings, quantitative
changes
of
vascular flow and flow velocity parameters (FVP).
Of 203 men, there were prostatitis 143 cases, nonprostatitis (prostatodynia) 36 cases, BPH 24 cases (among them 9 cases combined with inflammation). The quantitative criteria of flow were based on 3-point scale (grade 0-3) by Rickards or
supplementary
spot count. The control groujp was nonprostatitis.
1) Compared with control group, prostatitis and all BPH had more grade 2-3 (respectively p=0.04, p=0.035) and 20 BPH with inflammation had flow increase to BPH without inflammation (p=0.025), but BPH without inflammation had no flow increase to
control
group 9p=0.967). 3) Using the FVP, no significance was found in maximum flow velocity, mean flow velocity, pulsatility index or resistive index between prostate inflammation and control group.
We suggest that CDI rather than FVP is primarily related to the inflammation degree, and BPH alone does not affect CDI grade. So CDI can be applied clinically for the monitoring of treatment response in prostate inflammation.
