- What Are Kidney Stones?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Though I have had several attacks, and have listened to all my
- doctor's advice, I guess I have never really understood about my kidney
- stones. I know the symptoms, the pain is terrible, but what are they and
- where do they come from? Your answer would be much appreciated.

- ANSWER: You describe the pain accurately; it may be excruciating, and follows
- the path of the stone as it descends along the urinary tract. Yet there are
- some patients who never go through this torture, but have "silent stones" that
- may produce no symptoms at all, yet when x-rays are taken, there they are.
- Stones are formed from the minerals that occur in our urine. Normally they
- may form minute crystals that are passed out of our bodies along with the
- urine flow, but sometimes they clump together, and cling to the tissue lining
- the inside of the kidney. There they continue to grow as new crystals are
- added, and they harden as time passes. They may develop to any size, from a
- grain of sand to almost the size of an orange. A number of substances can
- form stones--calcium oxalate, calcium phosphate, uric acid, cystine, or
- struvite--and some stones are composed of mixtures of these substances. If
- you have had stones once, you are at risk of having them again. They occur
- mostly in middle aged people, and in areas where hot weather causes excessive
- sweating. If body fluids are diminished, the risk for producing stones is
- increased. It is the same with reduced or blocked urinary flow; these
- occurrences increase the possibility of stones. Certain genetic disorders as
- well as foods rich in oxalate and calcium may cause stone formation in some
- individuals. Despite the knowledge of all these factors as possibly
- contributing to the manufacture of these nasty pebbles, no one is really sure
- why they occur or why some people develop them while others do not.
