The infection is usually bacterial. The most common type of renal disorder, pyelonephritis may be chronic or acute.

Detailed explanation-4: -Outpatient oral antibiotic therapy with a fluoroquinolone is successful in most patients with mild uncomplicated pyelonephritis. Other effective alternatives include extended-spectrum penicillins, amoxicillin-clavulanate potassium, cephalosporins, and trimethoprim-sulfamethoxazole.
