Why when you cough does some urine leak out?

Stress incontinence: Urine leak with coughing is called stress incontinence and is more common in women, particularly those who have delivered children vaginally. If you are bothered by the amount and frequency of leakage, see a urologist or gynecologist for evaluation. A wide range of therapies, from pelvic floor muscle training, to medications, to surgical procedures are available depending on the cause.
