Great that you found this site. Best place on the net for info on PCa.
I can appreciate your husband's work concerns. I had just started a new position at work 2 weeks before my surgery. Despite my wife's protests, I was bound and determined to not miss a beat. Just the way I'm wired, and honestly, my wife is as supportive as they come :)
First off, I told them 6 weeks at work, because that's what everyone told me. Six weeks seemed like an eternity to me. I'll tell you that I took my first business trip running through O'Hare with my roller on suitcase and brief case as carry-on baggage at 5 1/2 weeks. And that was with open surgery. So it all depends on how he is feeling. I felt great and had little incontinence to contend with.
But I did not wait 6 weeks to work. I started the week following surgery, but from my guest bedroom (more specifically bed!). Mentally I felt great and didn't really have fatigue from surgery. But I could not sit upright for very long. On the bed with my feet up, I could recline against the pillow and had my laptop and papers on the bed with me. For me, it sure beat reading novels or watching day time TV...ugh. It energized me and made me feel like I was being productive and took my mind off the concerns I had about getting the cath out, whether my first PSA would be zero, etc.
So my recommendation to your husband is that he really make sure he doesn't push his body beyond any reasonable limits and that he be fair to himself depending on how he's doing post surgery. I hope they can give him the means to work remotely from home, because it's going to be challenging to get back into the office that soon unless they have a gurney he can recline in. My work was VERY supportive, and they all told me not to do anything I wasn't up to. I hope he will have the same support. Also, if he's truly concerned and can't go back to work for a more extended period of time, most companies offer a Family Medical Leave option if he's been there long enough.
I had only been at my company for less than a year, so this wasn't an option and I turned out not to require it, but it's just another option to consider in case things take longer for him.
In any case, I wish you the best will be watching to see how things go for you. Merry Christmas to you and your family. I hope my saga offers some encouragement that it may be feasible for him to do what he wants if he's feeling up to it.
Oh yeah, one more thing...I was told no driving until the cath was out. Had I been told it was ok, I probably would have been driving after I was off the pain meds about a week post surgery.
