Cystectomy yes or no?

I am a 63 year old male who had a radical robotic prostatectomy in the fall of 2017, did the radiation in early 2018.
Everything was good for about 18 months, then I started to pass blood, then started passing pieces of my bladder.
Had to go to the ER and Dr’s office numerous times. They showed me how to “self-cath” so I did this for the next 3 years, it got to where I was cathing more than 30 times a week.
Having to self-cath at work became a problem with all the UTI’s. (Warehouse environment)
I took early retirement in late 2021 because of the stress increase due to a change of management.
I had a Supra Pubic Catheter installed in June of 2022, this did get my bladder to quit “peeling” but the spasms were horrendous. Took it out in March of this year after the doc said my bladder was “the best he has seen it look.”
No stones or cotton candy, (his words not mine) .
I have had to self-cath a few times since.
The scar tissue and neck constriction is my problem.
The bottom line is my doc says the only thing he can do to give me at least some improvement in my quality of life is to do a cystectomy with an ileal conduit.
Doc says the radiation did too much damage to do anything else.
I’m looking for ideas. Not real fond of wearing the bag full time.
