Sorry I can't help much, but I do seem to remember some kitties here having blood in the urine even without infection. Did the vet check for crystals?
The only experience I have is with Peanut's bladder tumor. I knew within 3 days that her problem wasn't a urinary tract infection because there were bright red spots in her urine, not just a general redness to the urine. I took her back to the vet, he did an ultrasound and sure enough, he discovered her tumor. To be sure, you could ask your vet to do an ultrasound too.
Sure hope it's nothing serious and Oscar is completely healthy in no time!
