It does sound most like a UTI to me, even if he was at the vet a week ago, it could very well have developed in the intervening time. Back to the vet, get him checked, and clean that pillow with an enzymatic cleaner!
Back to the vet, yes. Clean the pillow and reuse, no.
I'd say get a new pillow. Nothing like sleeping on a pillow that's been peed on. ICK!
