Urinary incontinence, or involuntary leakage of urine, is common in older women. There are 2 main types. Urge incontinence is sudden, urgent urine leakage. Stress incontinence is urine leakage with coughing, sneezing, or physical activity. Some women have both types. It is currently thought that women must keep a diary of their symptoms and undergo full examination and testing for doctors to make an accurate diagnosis of incontinence. Most women and doctors avoid these because the diary is difficult to keep and the tests are complicated, invasive, and difficult to interpret. As a result, incontinence is not diagnosed or treated in many women. Women and their doctors would benefit from a simpler way to diagnose the different incontinence types.
