Oddly, I've found very few people mentioning that they use a clamp.
My Prostate cancer was found on a 'routine' PSA (strong family history), MRI showed a suspicious area, biopsy confirmed the need for treatment - Gleason 7 - and I opted for RRP, which went well. Histology showed 60% involvement of the prostate, but no breach of the capsule, and no gland involvement. The catheter came out after two weeks (November 5th) , and the expected incontinence was immediately a problem to get to grips with.
I've been lucky with being almost completely dry at night, getting up once on average. By day, it's a different matter. The mornings can be reasonable, but because physiologically one produces more urine in the morning, it can be an effort. Going out for a walk, or to do anything (shopping, jobs in the workshop etc) was really problematic. My surgeon, and also the urology physio, recommended trying a Dribble-Stop clamp. Yes, they cost a great deal more than you might expect for a small plastic device. But, what price continence?! The effect is amazing. I can do an hour's walk, or more, or be out all morning, perhaps lunch out. An occasional visit to the loo to release the clip and empty the bladder, is all that's needed. I never use it more than half the day. It gives the poor old pelvic muscles a rest, and makes it that much easier to cope with the rest of the day clamp-free.
Whether it can make the pelvic muscles lazy, seems to be a matter of dispute. But even if it does delay the full recovery of continence that we would all look forward to, it does mean that 'normal' life can carry on - visiting friends, going to the cinema, playing with the grandchildren. And that counts for a lot.
Glad to report that my first PSA was undetectable, no matter how hard they tried to find some!
What experiences have others had?
