Administer antimicrobial therapy, initially given intravenously, such as a third-generation cephalosporin, a fluoroquinolone, or an aminoglycoside. In patients with risk factors associated with an unfavorable prognosis, such as old age, debility, renal calculi, recent hospitalization or instrumentation, diabetes, sickle cell anemia, underlying carcinoma, or intercurrent cancer chemotherapy, the antimicrobial coverage should be broadened and an antipseudomonal agent should be added.

Adult males with UTI should receive a 10- to 14-day course of antibiotics. Outpatient regimens include a fluoroquinolone, trimethoprim-sulfamethoxazole (TMP-SMZ), minocycline, or nitrofurantoin (should not be given if glomerular filtration rate < 50). Treat the symptom of dysuria with phenazopyridine. [12, 13, 14, 15]
