title: Correlation between voiding dysfunction symptoms and uroflowmetry in women suffering from stress urinary incontinence.
abstract: OBJECTIVE
  To determine whether the completion of a voiding dysfunction (VD) questionnaire could have a good predictive value for uroflowmetry findings, in a population of stress urinary incontinence (SUI) women.
  
  
  METHODS
  From a urodynamic database of 415 SUI women, 93 with isolated SUI who underwent urodynamic investigations were eligible for this study. Patients with obvious etiologies of obstruction were excluded. VD symptoms were analyzed using the Bristol Female Lower Urinary Tract Symptoms Questionnaire. Bladder outlet obstruction (BOO) was defined as a maximal flow rate under 15 ml/s for a urine volume > 200 ml, or a post-void residual volume greater than 50 ml, or an abnormal pattern of the flow curve. The sensitivity, specificity, positive and negative predictive value of questioning VD were calculated. Statistical analysis was done using a Wilcoxon test for continuous data and Fisher exact test for categorical data, and multivariate analysis.
  
  
  RESULTS
  Reported VD had a poor specificity (41%) and positive predictive value (32%) of BOO on uroflowmetry. No statistical correlation was found between VD symptoms and BOO defined on uroflowmetry (P=0.64) in this specific SUI population showing no obvious etiologies of obstruction.
  
  
  CONCLUSIONS
  No correlation was found between obstructive symptoms and BOO as defined on uroflowmetry, in a specific population of SUI women. Our results suggest that uroflowmetry may be necessary rather than multichannel urodynamics.
