This contrasts with urine that leaks from extraurethral sources, such as fistulas or lower urinary tract congenital malformations. Although incontinence is categorized into several forms, this chapter focuses on the evaluation and management of stress and urgency urinary incontinence. Stress urinary incontinence (SUI) is the involuntary leakage of urine with increases in intraabdominal pressure. Urgency urinary incontinence is the involuntary leakage accompanied or immediately preceded by a perceived strong imminent need to void. A related condition, overactive bladder, describes urinary urgency with or without incontinence and usually with greater daytime urinary frequency and nocturia (Abrams, 2009).
