Pyelonephritis Disease and Labaratory Tests

Pyelonephritis is a bacterial infection of the kidneys, which are part of the upper urinary tract. Infection is more common in middle-aged or older. Often pyelonephritis starts from bacteria in the bladder that spread upwards to the kidneys. This infection may cause potentially life-threatening damage (acute kidney injury) and even lead to bacteria entering the bloodstream. For this reason, it is important to make a diagnosis and start treatment as early as possible.
