I have been caring for my Grandfather for 6 years. He is 98. I hate the chucks. They were such a pain in the you know what. I never thought about duct tape but then I would have gone through a few rolls a week at that rate.
We ordered the really thick depends and those really helped too. I purchased some very soft vinal 60" wide that had a soft fabric feel on the other side, at JoAnns. It was wide enough that I could tuck in under the mattress on both sides so it would not slip or bunch up. It worked great and Grandpa said it did not make him sweat against it like other waterproof protections. I kept 3 on hand to rotate as needed. I had considered buying a couple of those drain pads you can buy at Bed Bath and Beyond for draining dishes on. I have a couple of them and I am amazed at how much liquid they can hold and yet not be soggy like sheets on the bed can get.
He got so bad with the need to urinate so often and started falling at night when he needed to use the bedside commode, that for safety sake he ended up with a cathether. It made his life so much easier. When he finally could not stand and I could not lift him, we put him into a very nice nursing home here in town. At first they took the catheter out but quickly saw he was up at all times of the night and was making a lot of mistakes in the bed so they put it back in. Life is much better for him now. As long as he drinks plenty of liquids and cranberry juice he does just fine with it.
