The epidemiology of urinary incontinence: a case still open.

Urinary incontinence (UI) is a widespread and well-known disorder affecting millions of women all over the world with impressive and probably still underestimated rebounds on personal and social wellbeing. Unfortunately, the available studies on the epidemiology of female UI have used different definitions of UI, obtaining data not homogeneous. In a very recently published article, Bedretdinova et al. have demonstrated that UI definitions and sampling strategies both influence estimates of UI prevalence among women. The ICIQ-UI-SF questionnaire appears to be appropriate for estimating national prevalence in representative samples.
