Why would a urologist start a patient on a quinolone without having sensitivities to a urine culture?

Uti. Quinones or fluroquinilones are the first line in most cases.
No brainer. Te chances of a drug resistant bacteria to quinolones is much lower than other antibiotics. Pending sensitivities, great choice. Trust me, he didn't put you on it because he felt like it. We like to think we think ...
Poor practice. Any physician should obtain a urine culture before starting them on an antibiotic, especially a quinalone. Not doing so is poor practice.
