I have had bladder control problem for the past four years........

it all started four years ago when my bladder just muscles just suddenly quit. litterally just quit. my doctor at mayo clinic cant figure out why. i wear diapers all the time and was wondering if there is a better brand than depend that you can get on state medical aassistance. with a prescription. and does anyone have any idea what may have caused my bladder to just suddenly quit like that. i can still flow, but my urine and butt muscles do not work anymore. ps i need  an adult diaper that is not cloth like, and has a plastic like out backing and can hold 20 ounces of urine at ease. i am alllergic to the clost like diapers.
