Lots of people with little dogs use what's called a belly band, basically strapping an absorbent pad around their dogs. The problem with this is the quantity of urine output (big dog, more pee) can cause so much irritation to the skin. Much like a baby sitting in a wet diaper all day. Think about how often you change a baby and they still get diaper rash. And they seldom stay in place on a big dog.
At this age and condition, JMHO show this boy some respect and get a sitter. You may only have him for a short time. Might check with your vet and see if one of the staff would make a quick visit at lunch? Colleges have bulletin boards with local people trying to make extra money. Maybe if weather permits you could run to HomeDepot or Tractor Supply and purchase a fenced in enclosure and lock it? Get a dog house to keep comfortable!
But to answer your question, this is an option.
