What Causes A Kidney Infection?
As previously mentioned, a kidney infection develops from a urinary tract infection, specifically when bacteria enters the urinary tract through a tiny tube known as the urethra that carries urine from the body that then multiplies and travels to one or both kidneys. Specifically, the bacteria called E. coli generally causes the infection to begin with, and this is often the most common cause of a kidney infection. However, other infections can result in a kidney infection.
Bacteria from an infection elsewhere in the body can also spread and travel through the bloodstream to the kidneys, as although it is quite unusual for an infection to develop in this manner, it can happen if an individual has an artificial joint or heart valve that becomes infected. Rarely, a kidney infection occurs after a patient has kidney surgery, and it is also incredibly rare for an infection transmitted through the skin to travel through the bloodstream to the kidneys, but it can happen.
