Natalizumab (Tysabri) is a treatment for people with relapsing forms of MS. It makes flares happen less often and keeps physical disabilities from getting worse quickly.
Tysabri works in a different way from other multiple sclerosis drugs. It keeps the white blood cells of the immune system from entering the brain and spinal cord, which doctors think plays an important role in the damaging effects of MS.
When these methods or medicines do not help, you may have to use a urinary catheter, a thin flexible tube that you can insert into the channel through which urine exits the body (urethra). This is called intermittent self-catheterization. A little instruction and a few practice sessions with a nurse are all that are needed to learn to do intermittent self-catheterization. The procedure is usually done at the toilet.
Some people who have MS may only need to use the technique for a few weeks or months, because the bladder often recovers most of its normal function.
Urinary tract infections are common in people who have MS. Your doctor should check your urine whenever you have a flare-up, fever, or change in bladder symptoms.
