title: Are voiding symptoms really associated with abnormal urodynamic voiding parameters in women?
abstract: OBJECTIVE
  To examine the relationship between voiding symptoms and objective measurements of voiding dysfunction.
  
  
  METHODS
  We prospectively collected data from 116 consecutive women attending for urodynamic investigations. Symptoms of voiding dysfunction and objective voiding parameters including uroflowmetry and post-void residual volume were evaluated.
  
  
  RESULTS
  Sixteen (14%) patients reported a symptom of straining, 21 (18%) double voiding, 32 (27%) post-micturition dribbling, 10 (8%) poor stream and 34 (29%) incomplete emptying. Using receiver-operator curves we were unable to determine a cut-off value for flow or residual volume where symptoms became more prevalent. Poor stream was, however, a good predictor for a residual volume of >100 mL and >150 mL. Strain predicted a residual volume of >100 and >150 mL and it correlated with maximum flow rate <15 mL/s. The other three symptoms did not correlate with any of the cut-off values.
  
  
  CONCLUSIONS
  Poor steam and strain are weakly predictive of abnormal voiding function.
