What is the most common cause of pyelonephritis?
The main cause of acute pyelonephritis is gram-negative bacteria, the most common being Escherichia coli. Other gram-negative bacteria which cause acute pyelonephritis include Proteus, Klebsiella, and Enterobacter. In most patients, the infecting organism will come from their fecal flora.
What is the difference between pyelonephritis and UTI?
A urinary tract infection is inflammation of the bladder and/or the kidneys almost always caused by bacteria that moves up the urethra and into the bladder. If the bacteria stay in the bladder, this is a bladder infection. If the bacteria go up to the kidneys, it is called a kidney infection or pyelonephritis.

What is a urothelial cell?
Urothelial cells (UC) are classified as transitional epithelium, and they cover almost the entire luminal surface of the urinary tract.

How is pyelonephritis (kidney infection) evaluated?
A good history and physical is the mainstay of evaluating acute pyelonephritis, but laboratory and imaging studies can be helpful. A urinary specimen should be obtained for a urinalysis. On urinalysis, one should look for pyuria as it the most common finding in patients with acute pyelonephritis.
How can acute pyelonephritis be prevented?
For healthy, young, premenstrual women, one of the best ways to avoid acute pyelonephritis is to focus on prevention of one of the more common predisposing causes which are urinary tract infections.
