What Is Pyelonephritis?
2. What Causes Pyelonephritis?
The most common cause of a kidney infection involves bacteria entering the kidneys through the lower urinary tract. This bactera makes its way through the urethra, into the bladder, through the ureters, and into the kidneys, where it can cause acute inflammation and irreparable damage.
Pyelonephritis can also be chronic, which is often the case for those with other medical conditions or elderly people. These patients, oddly enough, may not have any pyelonephritis symptoms, which makes it a more dangerous condition.
