It looks like a lot depends on the complications encountered in the surgery. I'm 55. I had 5 small incisions that healed up pretty quickly. I was in the hospital for only 18 hours and had the catheter in for 2 weeks. That was the worst part of the whole thing. Didn't have any incontinence.
Right after it was removed I did a couple of long walks. I just got back from my 8th ride after surgery (5 weeks yesterday). The rides have been from 10-20 miles all fairly flat.
I bought a Planet Bike ARS saddle but never used it. It looked too cushy. So, I'm riding on my usual Terry Fly saddles.
Good luck and stay positive!
