title: [Uroflowmetry and its influence factors in benign prostate hyperplasia patients].
abstract: OBJECTIVE
  To determine the relationship between uroflowmetry and age, the course of disease, premicturition volume, transition zone index and proportion of stroma-to-epithelium in benign prostate hyperplasia (BPH) patients.
  
  
  METHODS
  Eighty-nine BPH patients in our hospital from 2000 to 2003 were evaluated. With the CMM3 pathology image analysis system, transrectal ultrasound and Dantec 2000 urodynamic instrument, the value of influence factors was determined. A linear regression was applied to analyze all the data by SPSS software.
  
  
  RESULTS
  The flow rate was correlated to premicturition volume ( r = 0. 477, P < 0.01) and proportion of stroma-to-epithelium significantly ( r = - 0.437, P < 0.05) , but was not correlated to the age, the course of disease and transition zone index significantly. The parameter of flow rate/premicturition volume had no difference in 3 micturitions in all patients.
  
  
  CONCLUSIONS
  The parameter (flow rate/premicturition volume)could be used to evaluate the micturition status of the BPH patients whose bladder volume is less than 200 ml. We should pay more attention to receptor blockers when we treat BPH patients.
