title: [Clinical features of benign prostatic hyperplasia complicated by chronic prostatitis].
abstract: OBJECTIVE
  To explore the clinical characteristics of benign prostatic hyperplasia (BPH) complicated by chronic prostatitis (CP).
  
  
  METHODS
  A total of 120 cases of BPH pathologically confirmed after transurethral resection of the prostate (TURP) were assigned to a BPH group (n=75) and a BPH + CP group (n=45) according to whether they were complicated by CP. The total prostatic volume (TPV) and PSA density (PSAD) were calculated and statistically analyzed based on the results of transrectal ultrasonography and f-PSA, t-PSA and f-PSA/t-PSA tests before surgery.
  
  
  RESULTS
  The BPH group showed a significantly upward tendency in f-PSA and t-PSA (P < 0.05) with the increase of age or prostate volume, but not significantly in PSAD and f-PSA/t-PSA (P > 0.05). In comparison, the BPH + CP group exhibited remarkable increases in f-PSA, t-PSA and PSAD (P < 0.05) but not in fPSA/t-PSA (P > 0.05). ROC curve analyses of various indexes showed the area under the curve to be 0.644, 0.628 and 0.624 for f-PSA, t-PSA and PSAD, respectively, all between 0.5 and 0.7.
  
  
  CONCLUSIONS
  BPH is frequently associated with CP. Clinically, high f-PSA, t-PSA and PSAD are important but not sure indicators of BPH complicated by CP.
