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.
