13 Signs and Symptoms You Might Have a Kidney Infection
A kidney infection originates from the bladder (cystitis) or the urethra (urethritis). The bacteria can travel through the ureter, which is what connects the kidney to the bladder, and infect the organ. The Inflammation of the kidney due to a bacterial infection is called pyelonephritis. If the infection in the bladder or urethra is treated in time, the bacteria should not go up to the kidneys; but if ignored for 2-3 days or more and the patient has a fever, the microbes probably ended up in the kidney resulting in pyelonephritis, Dr. Prince Mohan, M.D., medical director of transplant nephrology, Geisinger Health System, says.
