- What is a "Horseshoe" Kidney?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Here is a curious question, that has me very puzzled. After a few
- minor urinary problems, my doctor ordered some tests to help him figure out my
- problem. The results didn't reveal too much except the fact that I have a
- "horseshoe" kidney. My doctor's statement that it is nothing of consequence
- doesn't satisfy my curiosity. Can you offer me a bit more information about
- this condition?

- ANSWER: As you know, most people have 2 kidneys. They are normally about the
- size of your fist, shaped like a bean, and are located against the back wall
- of the abdomen, one on each side of the spinal column. The lower end of the
- kidney is at the level of the lowest rib. However, in some rare cases,
- because of a quirk of prenatal development, the two lower ends of the kidneys
- remain joined, resulting in what appears to be a single kidney with the shape
- of a horseshoe. However in most cases there are still two ureters that lead
- from the kidney to the bladder, and each side of the horseshoe functions as if
- it was an individual kidney.
- Most people with this congenital condition have no difficulties, but
- since the ureters must take a different route to the bladder than normally,
- they may be more prone to obstruction, that prevents urine from flowing to the
- bladder. And that can promote a situation that leads to frequent infections
- and kidney stones.
- Frequently the condition goes undetected and unsuspected. However when a
- special kidney x-ray test is performed, called an IVP (or an intravenous
- pyelogram) the pattern of the horseshoe kidney is seen on the x-ray. A
- special liquid called "contrast media" is injected into a vein in the arm.
- This liquid is opaque to x-rays, and as it collects in the kidney, and then
- runs down the ureter to the bladder, it outlines the shape and structure of
- these organs. The pattern produced by the horseshoe is quite unique, and the
- shape is quite like a horseshoe with the ends pointing upward. This alone is
- not a cause for alarm, and since your other tests must have been negative,
- your doctor's reassurance was in order.
