Therefore, the bladder fills up and overflows. Stress, urge and overflow all cause intravesical to exceed intraurethral pressures. But incontinence can also occur if intraurethral pressure is decreased. This happens in menopause. The mucosa around the urethra is filled with vasculature that is responsive to estrogen.
Menopausal women lack estrogen, sometimes enough to cause incontinence.
So a primary Rx is to give estrogen suppositories.
