The purpose of this study was to reveal parenchymal and vascular changes in acute prostatitis and to determine the role of color Doppler sonography in monitoring patients with this pathology.
Twenty five patients with a clinical diagnosis of acute bacterial prostatitis (NIH 1) admitted to our institution were studied prospectively. Clinical, analytical and microbiological data were recorded. Color Doppler and transrectal ultrasonography (TRUS) were performed 1 week after antibiotic therapy and afterwards at 6 weeks, 3 and 6 month visits. The findings were recorded and scored using standardized criteria to characterize the degree and distribution of prostatic vascularity.
Blood flow was observed to the entire prostate capsule (grade 2) in 23 (92%) patients at first visit (1 week) and were present in 11 (44%), 6 (24%) and 2 (8%) at 6 weeks, 3 and 6 month visits respectively. The amount and distribution of blood flow within the prostatic parenchyma were evaluated using several criteria. Using the 2-point scale flow were classified as grade 2 22 (88%), 18 (72%), 12 (48%) and 3 (12%) patients at first, second, third and fourth visit respectively. Similar findings were noted using the Doppler spot scale which revealed that flow was grade 2 (15 spots or more) in 23 (92%), 19 (76%), 11 (44%) and 3 (12%) patients respectively. Mean number of Doppler spots in the prostate parenchyma was 23.1 +/- 11.1 at first visit, 10.3 +/- 9.5 after the end of therapy and 8.3 +/- 5.4 and 7.9 +/- 5.1 at 3 and 6 monthly respectively.
Patients with acute prostatitis require prolonged treatment and subsequent follow up for at least 6 months. Color Doppler sonography is a useful tool in monitoring response to treatment and in predicting clinical outcome.
本研究旨在揭示急性前列腺炎的实质和血管变化，并确定彩色多普勒超声在监测该疾病患者中的作用。
对25例临床诊断为急性细菌性前列腺炎（NIH 1型）并入住我院的患者进行前瞻性研究。记录临床、分析和微生物学数据。抗生素治疗1周后进行彩色多普勒和经直肠超声检查（TRUS），之后在6周、3个月和6个月复诊时进行检查。使用标准化标准记录检查结果并评分，以表征前列腺血管的程度和分布。
初次就诊（1周）时，23例（92%）患者的整个前列腺包膜可见血流（2级），6周、3个月和6个月复诊时分别有11例（44%）、6例（24%）和2例（8%）可见血流。采用多种标准评估前列腺实质内血流的量和分布。使用2分制，初次、第二次、第三次和第四次就诊时血流分级为2级的患者分别有22例（88%）、18例（72%）、12例（48%）和3例（12%）。使用多普勒斑点量表也有类似发现，该量表显示血流分级为2级（15个斑点或更多）的患者分别有23例（92%）、19例（76%）、11例（44%）和3例（12%）。前列腺实质内多普勒斑点的平均数量初次就诊时为23.1±11.1，治疗结束后为10.3±9.5，3个月和6个月时分别为8.3±5.4和7.9±5.1。
急性前列腺炎患者需要长期治疗并随后至少随访6个月。彩色多普勒超声是监测治疗反应和预测临床结果的有用工具。
