What is the difference between stress, urge and mixed urinary incontinence?

The most common types of UI are “stress,” which involves increased abdominal pressure (sneeze, cough, laugh, etc) and “urge,” which is accompanied by urgency and/or bladder contractions. Mixed incontinence has both stress and urge components. This is the most common form of UI, and people will exhibit a higher percentage of one component over the other. For example, you may have frequent, sudden strong urges with leakage most of the time but occasionally also leak with a strong cough. That would be considered mixed UI with urge dominance.
