- pus and blood in the urine.
How is kidney infection diagnosed?
Diagnosis is made with a urine test to identify bacteria and formations of white blood cells, called casts, shaped like tubes in the kidneys. If an infection cannot be easily cured, x rays might be done to look for abnormalities in the kidneys, ureters, and bladder.

An untreated or recurrent kidney infection can lead to chronic pyelonephritis, scarring of the kidneys, and permanent kidney damage.
