Urinary incontinence (UI) is defined as the complaint of involuntary loss of urine. Urinary incontinence can be divided into several different types, including stress urinary incontinence (SUI), which is defined as the complaint of involuntary loss of urine on effort, physical exertion, sneezing or coughing. Mixed urinary incontinence (MUI) is defined as the complaint of involuntary leakage associated with urgency and effort, exertion, sneezing and coughing. Urge urinary incontinence (UUI) is defined as the complaint of involuntary leakage accompanied by or immediately preceded by urgency; overflow incontinence, and functional incontinence. This book reviews UI's prevalence, risk factors and the management strategies currently available.
