For two years I have been on Mybetriq (prior to that on Vesicare for a year). All that time, I was searching for a uro-gyn who offers percutaneous tibial nerve stimulation in my area (Washington DC metropolitan area). Finally found one!
I've had only two treatments so far but the improvement is really noticeable. Most days NO LEAKS.
He told me that 80% of MS patients see improvement but that improvement does not necessarily mean complete control.
After years of misery - can't even take a one-hour walk - I'll be happy for any improvement!
Here's a fairly recent study of outcomes:

And another, specific to neurogenic bladder:

I also considered getting the ankle implant (Revi) but my insurance doesn't cover it.
