Objectives: 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. Materials and 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.
