If your biggest problem is constantly rushing to the loo, I'd consider having a chat with your doctor/consultant about botox injections into the bladder.
It sounds worse than it is.
I've got MS, have been having them for about 14years and they work for my bladder issues.
Before I started the injections, I could go to the loo, walk straight out of the house, drive the 8minute journey to work, and regularly pee myself before I got there, and have to turn round and come home to shower again and change my clothes. Nighttime loo visits were practically every hour on the hour.
Since starting the injections, I can go all night without a loo visit.
The treatment is a camera passed up into the bladder, local anaesthetic gel and about 20 tiny injections around the inside lining of the bladder. They pinch a bit but the whole thing is over in less than 10mins.
Generally, each treatment lasts between 10 and 14 months, they work a bit longer than this for me.
Even after my first treatment, my son noticed within a couple of days that I wasn't constantly running to the loo, and I'd spent years terrified of going anywhere if I didn't know I could find a loo within literally a minute.
Yes, the tiny pinches are a bit uncomfortable, but I count them off and I know I've got around 16 months of feeling normal before I have to go and have it redone.
If this is possible for you, it's far less invasive than an operation, and might help enormously.
It's definitely worth a conversation with the docs.
