[Evaluation of transrectal longitudinal ultrasonography of chronic non-bacterial prostatitis]

Transrectal longitudinal ultrasonography was performed in 34 patients with chronic non-bacterial prostatitis. Prostatic stones and cystic lesions were associated with chronic non-bacterial prostatitis in 67.6% and 11.8%, respectively. The annual relapse rates of clinical symptoms were related to the presence of prostatic stones and cystic lesions. Transrectal ultrasonography plays a very important role in predicting the clinical courses of chronic non-bacterial prostatitis.
