Kidney infection typically occurs when bacteria enter your urinary tract through the tube that carries urine from your body (urethra) and begin to multiply.
Bacteria from an infection elsewhere in your body also can spread through your bloodstream to your kidneys. Kidney infection is unusual through this route, but it can happen — for instance, if you have an artificial joint or heart valve that becomes infected.
Rarely, kidney infection results after kidney surgery.
