What we do, as my father has the same issue, is this...I have a fitted mattress pad over the entire mattress, then a crib size waterproof pad over that, then the sheets, then a fabric waterproof mattress protector and I have him wear super absorbency disposable underwear.
I would highly suggest the fabric waterproof mattress protectors rather than the blue 'pee pads' or chucks. Yes, you need to wash them but they are much less likely to bunch and get out from under the area needing protecting. Don't wash them with fabric softener or they'll become less absorbent. The ones I have are plaid and are made by RediMedica (I think) and are about 3 feet by 3 feet or a little smaller. They cover almost the entire width of the twin mattress and from the edge of the pillows to below his rear enough to protect the bed. They are a lifesaver. I got them on ebay but I'd wager medical supply places have them too.
