I once got a kind of bag, can't remember the medical name for it but the idea is like this: (or so the paperwork it came with told me)
You attach the hose to your privates and then the bag part to your body and it works like a kind of portable catheter. great for people in triathlons and can't stop to pee (again, so they they told me) it's in my first aid box lmao!!
