Over 11 million women in the United States suffer from stress urinary incontinence (SUI), the involuntary leakage of urine during routine physical activities such as laughing, coughing, exercising, or sneezing. SUI affects women of all ages and can result in significant emotional distress. The purpose of this study is to evaluate a non-surgical, investigational treatment intended to reduce or eliminate urine leakage due to stress urinary incontinence.
