Stay positive! That's what I've been told on this forum time and time again, and it really is important.
At the same time, help prepare him for a less-than-positive experience when the cath comes out. I was not prepared for the gushing but that's what happened... and it still happens seven weeks post surgery. I felt my life was over... that I could never live with all of that pee-wee gushing out, etc. The incontinence was the worst it could be and no one spelled out the possibilities. I was prepared for "leaks", not for gushes.
The positives I had going for me was that (1) I found this web site and (2) I am gradually getting better. I'm getting better not in giant leaps, like some here, but baby-step by baby-step. (3) The Lord is helping me.
I had to visit my dermatologist the day after the cath came out. I was so humiliated because the nurse had to find something for me to pee in when I released the penis clamp (I didcarded that thing quickly) and the dermatologist had to hold the urninal type thing as I stood there trembling and ready to burst out crying (I did cry some, but not where anyone else could hear me, except my wife... bless her). The dermatologist offered much more sympathy to me and offered much more help than my surgeon, who was in-and-out too quickly. One thing he said that still stays with me was "This will pass." I saw him again recently and he said, "Boy, you're doing much better than you were before." Amen.
So stay focused and positive. This will pass. And prayerfully the path report will be good. If it's not, there is still lots to be done for him, as you know.
I too decided agains the Depens underwear and go for the Depends pads, even though I have to change them several times a day. If I had to change the underwear I'd have to take my pants off every time. And the pads don't show.
