Treatments for incontinence in women can include surgery to place a sling underneath the urethra. This can be done with minimally invasive surgery, making only a small incision in the vagina itself. Other treatments for incontinence include an artificial urinary sphincter, which is usually for men, but can also be used for women. Non-invasive treatments for incontinence include the Emsella chair which uses magnetic energy, focused on the pelvis, to strengthen the muscles of the pelvis and relieve incontinence. Incontinence can also be treated by injection of bulking substances inside the urethra. Another treatment for incontinence is called InterStim, using electrical stimulation to the nerve that goes to the bladder. A small implant about the size of a pacemaker is placed in the buttocks , and can treat the incontinence for up to 10 years.
