That isn't crazy. They actually make cushioned clamps that go around the penis. However, this is not a good idea for at least three reasons. One: you can imagine how it would show under one's clothes (a la "Is that a gun in your pocket or are you glad to see me?"); Two: you don't want to put back pressure on the tubes that come out of the kidneys into the bladder when the bladder contracts to start urination and there is nowhere for it to go but back up. You can really mess up your kidneys that way, and that can be a whole other life-threatening problem; Three: all the docs want people to learn to use the muscles on the floor of the pelvis to act as a urinary sphincter to take over for the one removed with the prostate, because this is more "natural."
They also make catheters that have a condom on them, and that have adhesive on the inside of the condom, so that you can put this thing on the outside of the penis and drip into a bag through an attached tube. Most docs hate those, too, because the inside of the tube and condom become breeding grounds for bacteria that can give you a heck of a urinary tract infection, with the possibility of messing up the kidneys, as well.
Good idea in principle but doesn't work that well in practice.
