전립선염 및 전립선대비증의 색 도플러 초음파 영상

Abstract

To evaluate the diagnostic value of color Doppler ultrasonography in prostatitis and benign prostatic hyperplasia (BPH), we have analysed the patterns of color Doppler image(CDI), expressed prostatic secretion (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 doppler spot count. The control group was nonprostatitis. 1) Compared with control group, prostatitis and all BPH had more grade 2-3 (respectively p=0.04, p=0.035) and 2) BPH with inflammation had flow increase to BPH without inflammation (p=0.025), but BPH without inflammation had no flow increase tocontrol group (p =0.976). 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.
