- QUESTION: I know that you as a physician must have heard about
- pyelonephritis, but it is a new and disturbing disease for us. I know it has
- to do with a kidney infection, but little else. What is it, and how do
- doctors diagnose and treat it?
-

-
- ANSWER: You are correct. It is an infection of the kidney, but the term
- pyelonephritis refers to the fact that the infecting bacteria strike both at
- the tissues of the kidney and the renal pelvis. The renal pelvis (from the
- Greek "pyelos" which means pelvis) is a funnel shaped structure that forms the
- upper end of the ureter, where it joins the kidney. The ureter, a tube-like
- organ, carries the urine from the kidney to the bladder.
- The most common cause of pyelonephritis is a bacterial infection, and the
- most common bacteria is Escherichia coli, which accounts for about 75 percent
- of these infections. The bacteria find their way to the kidney by ascending,
- moving up the ureter from the bladder, where they locate after entering
- through the urethra (the tube which leads to the bladder from the outside of
- the body). Certain conditions make it easier for the bacteria to reach the
- kidney, such as obstructions in the ureter, kidney stones, enlargement of the
- prostate gland, scars from previous infections of the urinary system, and poor
- emptying of the bladder. The infection is more common in women, especially
- during pregnancy, or in older women when they suffer from a "falling uterus".
- It also often occurs after catheterization of the bladder, when tubes inserted
- into the bladder provides a route for the bacteria to follow and enter into
- the system. This is particularly true in patients who suffer from diabetes.
- Usually the onset of the infection is swift, with chills, fever, pain in
- the flank, nausea and vomiting. In about 1/3 of the cases, there is urination
- frequency with pain. Often a tender and enlarged kidney can be felt by the
- doctor performing the examination. Testing the urine for blood and cells
- and culturing the specimen for the presence of bacteria can offer the final
- proof of the diagnosis. Antibiotics provide effective treatment, which should
- be started as soon as the diagnosis is confirmed. While oral medications are
- usually adequate, they can be administered by intravenous drip if the
- infection is severe.
