title: [Clinical analysis of benign prostate hyperplasia with prostatitis].
abstract: OBJECTIVE
  To analyze the clinical features of benign prostate hyperplasia (BPH) with prostatitis and the role of prostatitis in progression of BPH.
  
  
  METHODS
  From July 2003 to Feb. 2009, 466 patients diagnosed BPH were enrolled in this study. Several items including age, history, IPSS, volume of prostate, prostatic special antigen (PSA) and related parameters, Qmax, acute urinary retention (AUR) and the way of treatment were analyzed.
  
  
  RESULTS
  A total of 423 patients were diagnosed as BPH with prostatitis (90.77%, PS/BPH group), and 43 were BPH without prostatitis (9.23%, BPH group). Compared with the BPH group, patient's history of the PS/BPH group was longer, IPSS/QOL was increased, the volume of total prostate and transitional zone were larger, maximum flow rate was decreased and risk of AUR was increased, and the proportion of BPH-related surgery was higher.There was no significant difference in patient's age, tPSA, fPSA, f/tPSA, and PSAD between the 2 groups.
  
  
  CONCLUSIONS
  Prostatitis may be one etiological factor for BPH. Patients with inflammation were more likely to progress clinically in terms of lower urinary tract symptoms (LUTS), acute urinary retention (AUR), or BPH-related surgery.
