I'm unclear of the purpose, or nature, of your question. The two statements you posted are contradictory.

About the only home remedy I know of for simple UTI is cranberry juice. Not a blend, the real McCoy. In some markets you can get the Ocean Spray concentrated version, unsweetened. It's like Buckley's Cough Syrup in terms of how yummy it is, but it should do the trick if you have only a minor problem.

Note, though, that the acid in the juice might make things worse for you if you have some kind of inflammation or irritation that is not an infection.

This is where you seek help from maybe a urologist?
