title: Acute prostatitis in middle-aged men: a prospective study.
abstract: OBJECTIVE
  To determine the clinical outcome of middle-aged men with acute prostatitis, the optimum time for re-assessing their prostate-specific antigen (PSA) levels, and to detect any possible echotextural and vascular changes that remain as a consequence of acute inflammation.
  
  
  METHODS
  Persistent fever prompted a re-evaluation for prostatic abscess formation in 28 middle-aged men, using transrectal ultrasonography (TRUS) colour Doppler imaging, undertaken at the 3-, 6- and 12-month visits. The results of TRUS were compared with laboratory data and clinical outcome.
  
  
  RESULTS
  Two abscesses were detected; 19 (68%) of the patients remained infection-free at the 3-month visit. Serum PSA levels were elevated in 11 (39%) of the patients at this visit; three prostate carcinomas were diagnosed. Increased intraprostatic colour flow was detected in 68% and there were hypoechoic areas in 46% of the patients.
  
  
  CONCLUSIONS
  The re-evaluation for abscess formation should not be postponed for > 48 h. Patients with acute prostatitis tend to have persistent infection. PSA levels could be high even up to 3 months after an acute episode. Middle-aged men with carcinoma could be missed during the acute phase of inflammation. PSA and TRUS monitoring are strongly recommended.
