Hey Jeff
First, everyone is different! I'm 43 so our issues are pretty similar though. For me, I was told not to drive a vehicle for 6 weeks. I probably could have driven at 5, but the instruction from the docs would invalidate my insurance for 6! You need to be able to do an emergency stop effectively was the reason given. Raking tree limbs may take a bit longer but I was doing basic garden work at 2 months and, for example, I cleaned the whole house yesterday including hoovering. At 5 weeks from hospital I was also doing all my own cooking. Don't push it though. Stressing abdominal wounds can wind you up with a hernia which you don't want!
When I first came out of hospital I had my girlfriend staying with me. It's essential that someone is on hand like this for the first few weeks as I couldn't even boil an egg and brushing my teeth made me exhausted. Also, depending on your surgery, you may have tubes and things to manage and, with your brain not working 100%, it's good to have someone around to help. You'll be up all night for a while dealing with saline and urine.
When I say 99% during the day I would also add that, for me, it's not been a constant process. I may get 99% one day then go back and have a bad day. But if I look at the curve over a longer period there is improvement. All in all I'm pretty happy with progress.
On the nerve sparing, I personally could tell within 4 weeks or so that something down there was ok. But I know it can take many months for some people. My surgeon believes that the sooner you get using it again, the sooner it comes back to life if the sparing has been successful or partially successful. I doubt I'd get a full erection right now without drugs but I'm very happy that it's working really well with them.
I too have been told that the neobladder can be converted to a pouch down the line. But, though the chances are better, even a pouch cannot guarantee no leaks. I'm going to give my neobladder at least a year before I even think about a convertion and I've absoloutely no reason to believe it'll be necessary.
I think I am developing a feeling to go that is quite similar to before. Certainly if I approach the maximum current stretch of my new bladder I can feel it and this is often when I get a bit of leakage. Leakage is just an occupational hazard right now but it is improving. I worry less and less about it each day. I'm still stretching my bladder (I hope to go 4 hours before too long) and then, I believe, as long as I go within that time, leakage should be minimal. I wear a pad every day but there are days when I probably don't need it.
I'm amazed at how close to normal I feel with the neobladder. In fact, if I'd known how my disease was going to progress and how the neobladder worked, I would have done it sooner probably. The surgery is pretty gruelling; I think anyone here with a neobladder will tell you this, but it is definitely very getthroughable! You have bad days and setbacks and weird, unpleasant feelings and side effects but gradually you normalise. I've met people with pouch, neo and bag and all cope with their new appliances with equal aplomb. Your mind has incredible adjustment capabilities.
It sounds like you've been through the mill already so I'm sure, if it comes to it, you can deal with the op. I'd been treated for BC for 14 years. I'm sure from a standing start it's harder. If you have any questions please ask away. I'll answer anything I can.
Best Wishes
Tim
