I agree with Spirite, that the vet wants to keep him there, tells me he/she's concerned about your boy, and want to keep him monitered for any life threatening situations!
When a male cat blocks, and doesn't get to a vet, it can cause a very painful...end...ðŸ˜*
Once they block, they are more prone to having it happen again...
What you need to find out, is what type of Crystals/Stones your boy is dealing with...one type can often be controlled with a diet change (will dissolve), the other kind will require surgery (doesn't dissolve), than will still need to be on a specific diet, to keep them from forming again.
Both kinds will need antibiotics tho'...
The blood in his urine shows that what he's experiencing, is causing damage inside his bladder and urethra, and is very painful for him.
Wishing you and your boy, a Safe, and Speedy recovery!

An everyday family name; A particular name;
And the name but the Cat Himself Knows, and will never confess." T.S. Eliot
