Transrectal ultrasonography of the prostate cannot be used to formally diagnose CBP. Although hypoechoic lesions representing calcifications within prostate may suggest the infection and inflammation associated with CBP, these findings are highly nonspecific. Transrectal ultrasonography findings may also help to identify prostatic stones. In certain patients with frequent recurrences, these stones may be a contributing factor in CBP.

Transrectal ultrasound is useful only if a prostatic abscess exists. Abscesses are extremely rare, but if they are present, patients may also have a high fever and appear quite ill. CT scanning may also be helpful in this situation if transrectal ultrasonography is not available. MRI may also be used but is not as readily available in most acute situations.
