Stress urinary incontinence (SUI) is a leakage of urine during moments of physical activity that increases abdominal pressure, such as coughing, sneezing, laughing, heavy lifting or exercise. Stress incontinence is the most common bladder control problem in young and middle-aged women.
Stress incontinence occurs when the muscles and other tissues that support the urethra (pelvic floor muscles) and the muscles that control the release of urine (urinary sphincter) weaken.
