Color Doppler ultrasonographic scanning in prostatitis: clinical correlation.

Color Doppler and endorectal ultrasonography were performed in 25 patients with acute prostatic syndromes (APS; 13 acute and 12 chronic recurrent forms). In addition, 7 patients with asymptomatic chronic prostatitis, 13 men with prostatic carcinoma and 6 healthy young volunteers were studied. In the 25 APS, a marked increase in color was observed in the cervicourethral site and/or around the ejaculatory ducts and close to the seminal vesicles. The observed pattern is probably explained by vessel dilatation due to acute inflammation. The color increase in these 25 patients was greater than in the 6 normal prostates and 8/9 prostate carcinomas. Moreover, we observed that color intensity matched the severity of symptoms in APS.
