How are kidney infections treated?

The doctor will treat kidney infections with appropriate antibiotics. The urine and blood examination involves finding which antibiotic will work the best in the given infection. If the general condition of the patient is stable, they are given antibiotic pills that can be taken at home. In the case of seriously ill patients or patients with severe vomiting, hospital admission may be done. Such patients are given antibiotics and fluids through the vein (intravenously or IV). The doctor may give other medications, such as painkillers and antiemetics (medications that prevent vomiting). A urine culture may be done to know whether the infection has cleared, and the antibiotics may be given for a longer duration if needed.

In patients with problems, such as kidney stones and structural abnormalities of the urinary tract, surgery may be done.
