My cat can't pee after PU surgery, meds failed. What should I do?

My 13 y/o chubby male cat just had PU surgery 10 days ago but is still suffering from inflammation, urethral spasms, and unable to urinate on his own. They've had to put catheters in him 3 x's since his surgery. Prazosin is not working (he's been taking it for 1 month), we've tried Onzior with Valium for 3 days (that got him to pee once a day). But those were short term meds. He was then switched to Phenoxybenzamine along with xanax. That made him dizzy, very lethargic, dazed, diarrhea, vomited,

It sound like you have a great vet! Some cats are very hard to manage. You may discuss with your vet using steroids or placing a catheter for several days in a row and placing Georgie on IV fluids. Cerenia is an anti-nausea medication that can help with some types of inflammation. Adequan can also be used in cats with bladder issues, though it may take several weeks to be effective.
