Prevalence of "complicated" stress urinary incontinence in female patients: can urodynamics provide more information in such patients?
OBJECTIVE
The role of urodynamic investigation has been recently questioned on the basis of data from a selected population of patients with stress urinary incontinence defined as uncomplicated. The aim of this study was to determine the proportion of patients who underwent urodynamic investigation in our centre in whom the stress urinary incontinence could be defined as uncomplicated. The secondary aim was to assess the number of women in whom the urodynamic investigation added information to the preurodynamic assessment.


METHODS
This was a retrospective single-centre study. The data from female patients who underwent urodynamic evaluation prior to surgery for stress urinary incontinence between 2008 and 2012 were considered. Patients were categorized as presenting with uncomplicated or complicated stress urinary incontinence according to the definitions used in the ValUE trial. Urodynamic observations were then compared with preurodynamic data.


RESULTS
Data from 244 female patients were considered. Due to incomplete data, 33 of these patients were excluded from the evaluation. Only 47 patients (22.3 %) were considered to have uncomplicated stress urinary incontinence according to the definition used in the ValUE trial. The remaining 164 patients (77.7 %) were considered to have complicated stress urinary incontinence. Urodynamic observations differed from the preurodynamic data in 134 of 211 patients (63.5 %). A diagnosis of voiding dysfunction was obtained in 25.6 % of patients.


CONCLUSIONS
The majority of our patients had complicated stress urinary incontinence. In a relevant percentage of these patients, a urodynamic test added some new information, including a diagnosis of voiding dysfunction. The role of urodynamic investigation needs to be explored in this patient group.
