What Are Kidney Stones: NIDDK (Excerpt)
There are four major types of kidney stones.
- The most common type of stone contains calcium (KAL-see-um).
Calcium is a normal part of a healthy diet.
Calcium that is not used by the bones and muscles goes to the
kidneys. In most people, the kidneys flush out the extra calcium with
the rest of the urine. People who have calcium stones keep the calcium
in their kidneys.
The calcium that stays behind joins with other waste products to form
- A struvite (STROO-vite) stone may form after an infection in
the urinary system. These stones contain the mineral magnesium
(mag-NEE-zee-um) and the waste product ammonia (uh-MOH-nyuh).
- A uric (YOOR-ik) acid stone may form when there is too
much acid in the urine. If you tend to form uric acid stones, you may
need to cut back on the amount of meat you eat.
- Cystine (SIS-teen) stones are rare. Cystine is one of the
building blocks that make up muscles, nerves, and other parts of the
body. Cystine can build up in the urine to form a stone. The disease
that causes cystine stones runs in families.

Kidney Stones: NWHIC (Excerpt)
Kidney stones may contain various combinations of chemicals. The most
common type of stone contains calcium in combination with either oxalate
or phosphate. These chemicals are part of a person's normal diet and make
up important parts of the body, such as bones and muscles.
A less common type of stone is caused by infection in the urinary
tract. This type of stone is called a struvite or infection stone. Much
less common are the uric acid stone and the rare cystine stone. (Source: excerpt from Kidney Stones: NWHIC)
