ABSTRACT
Historically, urinary incontinence is divided into 3 subtypes: stress, urge and mixed. This latter group, which according to many studies can account for up to 50% of the patients, is very heterogenous. For this same reason, the reports of treatments of urinary incontinence are very difficult to analyse using this simple classification. In a attempt to clarify this situation and to help the acquisition of useful clinical information relating to urinary incontinence, were have developed a clinical classification of urinary incontinence (FPSUND) in which 6 symptoms are graded in severity from 0 to 3. In this acronym, the F stands for frequency, the P for the use of protection, the S for stress-related complaints, the U for urge-related complaints, the N for nocturia and the D for the number of daily micturitions. Urologists across Canada were sent the French or English version of the classification and used it to evaluate 148 female patients aged from 18 to 70, suffering from urinary incontinence. A second, independent evaluation, was also performed on the same patients by registered nurses or urodynamic technicians. Reproducibility between observers, as assessed by the weighted Kappa score ranged from 0.47 and 0.74 (p < 0.05), was very good. Generally, the users of the classification found it very easy to use. In summary, we propose the FPSUND clinical classification of urinary incontinence as a useful and accurate tool to classify urinary incontinence and as a means to assess treatment outcome.
