Diagnosis

To check for a kidney infection, you may be asked to provide a urine sample to test for bacteria, blood or pus in your urine. Your health care provider might also take a blood sample for a culture. A culture is a lab test that checks for bacteria or other organisms in your blood. Other tests might include an ultrasound, a CT scan or a type of X-ray called a voiding cystourethrogram. A voiding cystourethrogram involves injecting a contrast dye to take X-rays of the bladder when full and while urinating.

Treatment

Antibiotics for kidney infections

Antibiotics are the first line of treatment for kidney infections. The drugs used and the length of time of the treatment depend on your health and the bacteria found in your urine tests. Symptoms of a kidney infection often begin to clear up within a few days of treatment. But you might need to continue antibiotics for a week or longer. Finish taking the full course of antibiotics even if you start feeling better. Your provider might want you to have a repeat urine culture test to make sure that the infection has cleared. If the infection is still present, you'll need to take another course of antibiotics.

Hospitalization for severe kidney infections

If your kidney infection is severe, you may need to go to the hospital. Treatment might include antibiotics and fluids through a vein in your arm. How long you'll stay in the hospital depends on how severe your infection is.

Treatment for recurrent kidney infections

An underlying medical problem such as a misshapen urinary tract can cause you to have repeated kidney infections. In that case, you might be referred to a kidney specialist (nephrologist) or urinary surgeon (urologist). You might need surgery to repair a structural problem.
