blimey. a lot in common.
I was digging garden and DIY, after about 3 months. minimal scaring. However . this is a major op. extensive damage . etc. I was only in overnight. Golf .. swing can be quite intense. take it very easy. I still get quite extensive groin aches, the bladder seems to think it's full when it isn't. However flow is far better than it's been for years and I can hold 300ml plus probably more so life is good. For me and I believe others post op. the biggest challenge was constipation and getting the gut moving again. it might have been a combination of drugs, 4 hr op etc. It took me about 10 to 14 days to feel comfortable.
Absolutely no problems since.
I was up and about within 24 hrs. The catheter awkward at night to get solid sleep, not painful though. I kept a good flow of water intake, no alcohol or caffeine. Seemed to work for me.
take care and all the best
