After my prostatectomy in 2005 resulted in open-pipe incontinence, I used pads for a few years.
Then tried Cunningham Clamps during the day with a moderate absorbency pad over that. Over night I went with a pad alone and got up typically about twice a night. I took an oxybutynin tablet each day.
With the clamp, I'd have to drain about every 2 hours. Just sitting in a movie theater and not getting up/down till the end, I could make it through the film.
Tried to reposition clamp after each drainage proximal or distal to even out the pressure on the skin. Clamp has several tightness settings. I used the loosest, reserving the tighter ones for "reach-in" times I was concerned I wouldn't make it to the lav. Within the arms of the clamp are malleable metal strips that can be bent to attain a proper tightness.
Over the years there were problems with dilation of my urethra proximal to the clamp and my bladder never seemed to get a capacity of more than about 100 CC's. Off & on there were some skin issues. Clamps were about $35 and I'd go through about 3 a year, plus the pads.
For the past 2+ years, I've figured out a system to use condom catheters and collection bags. I empty about every 4-6 hours. Still use clamps during times I have the condom off.
