He's pretty old and like I mentioned it runs in the family and no one mentioned to the doctors they took him to that he'd been catheterized because it seemed so unrelated, but one of my aunts managed to put the pieces together and get him on an intense UTI treatment plan and he bounced back
You can get UTI test strips OTC (sometimes the 7-test urine strips are paradoxically cheaper).
Elderly care facilities will often have a big bottle and dip the pee on anyone who starts acting unusual, because the quicker you can catch it, the quicker you can treat it. Older people have less of a functional margin when it comes to illness, so the UTI that has you feeling crappy will have a great-grandparent nonverbal or punching people.
Older people also lose the ability to localize the urinary pain/discomfort, so that's why we don't get easy clues like a confused person who can still say "ow, my pee hurts." The change in urine smell and continence can sometimes help, though.

Cranberry juice tastes great but the sugar outweighs the biofilm busting.
Everyone prone to UTIs needs urine test strips, though. You don't know when you're going to get a "silent" UTI that's just malaise for a week before your pee finally hurts, and you need to be able to check to make sure a D-mannose or fish-mox self-treatment really took it down.
Even if you're going to call in to your doc's service for antibiotics, being able to say "yeah I have test strips and they said I have leukocytes ++ and nitrites ++" makes you sound way more credible to whoever's answering the phone and makes it more likely they'll call in the script without making you jump through hoops.
I just realized: does the average young man know about phenazopyridine? OTC med, brand name Pyridium, but I'm realizing it's always in the lady problems section of the store, not the drug section. It treats the pain/irritation of UTI (and it's fast and amazingly effective at it) but it's symptomatic management only, not antibiotic.
Phenazopyridine is a azo dye so if you're going to be peeing in a cup/on a strip, don't take the pills until after you've done that, because your pee is going to be a beautiful orange.
