The chronic prostatitis/pelvic pain syndrome was associated with increased blood flow to the prostatic capsule and diffuse flow throughout the prostatic parenchyma. Despite technical limitations, color Doppler ultrasonography may provide objective documentation of prostate blood flow abnormalities in patients with this syndrome.

With current ultrasound imaging technology, epididymal flow was demonstrated not only in the head but also in the body and tail of the epididymides of all of our healthy volunteers. Thus, detection of flow in the epididymis at color Doppler imaging can be a normal finding and does not necessarily imply epididymitis.

Transrectal sonography revealed that prostate vascular flow increases dramatically after ejaculation and remains elevated for at least 24 hr. This observation should be considered when power Doppler sonography is used to assess for potential hyperemia in patients suspected of having prostate abnormalities.
