Using anticholinergic medication with or without self catheterization can allow for bladder control under most circumstances. However with progressive MS there may be significant weakness of the hands or real ataxia of the arms. The idea that one should avoid a Foley catheter at all costs is simply not practical and causes many to have misery with ongoing incontinence. Upper urinary tract dysfunction is rare in MS despite frequent bladder infections. When it happens it must be treated aggressively with antibiotics and fluids.
Foley catheters allow families to go out without worrying where the bathroom is.
It saves husbands from going into the ladies room and vice versa. Foley catheters will always have an infection in them. The catheter is changed monthly. The person's fluid intake must be increased to obtain a good urinary flow. Sexual aspects to a Foley should be discussed and the placement of the catheter in the suprapubic region can remove that impediment.
