The good news - things seem much better than we feared. My dad was told he would need a catheter for life, but apparently it cae out when on holiday in Mykonos, where it could not be reinserted, but the doctors told him he was emptying his bladder anyway.
The consultant today said that this was because his treatment had shrunk his prostate so he was happy for him to carry on without - not only that he probably won't need the op on his kidney as the flow to his bladder is much improved.
The injections he is on should only be 12 weekly, but he has had them monthly. No long term effects from this - just an unnecessary extra cost to the taxpayer.
He has to have another PSA test and will see the consultant in 2/3 weeks, and have a scan on his bladder to check it is being emptied.
So all in all - things are looking much better for the short/medium term, and at 85, that is as much as could be hoped for.
