From personal experience, Dribblestop does work but a) is very expensive for a simple bit of plastic, b) can be painful c) needs to have the foam pads stuck back on from time to time and d) can come undone at the most embarrassing times. However, on the general scale of effectiveness of incontinence aids that are not intrusive, it's not too bad. The Conveen solution is cumbersome, but effective and (on the Welsh NHS anyway) is free of charge because the bits come on prescription.
Before going down the surgical path, I tried a few other "solutions" but found they were tending towards snake oil.
Yes, I sympathise. The problem is with so many other men having problems with ongoing high PSA, CT, RT and post operative issues, why are we incontinents making a fuss over a bit of wee? Because without a really strong personal mental state, incontinence just eats away a you. And, no, it doesn't help to be told you are not doing pelvic floor exercises properly. Please don't get me started on that subject. Experiment. Find the solution that works best for you (and is within your budget) and resolve to try to get on with life as best you can.
For the engineers out there, if you can land a spacecraft on a comet goodness only knows how many million miles away, you can come up with a solution to this problem that works!
