What are kidney stones?

Kidney stones, usually comprised of a compound called calcium oxalate, are the result of a build-up of dissolved minerals on the lining of the kidneys. These deposits can grow to the size of a golf ball, maintaining a sharp, crystalline structure.

A kidney stone is a hard mass developed from crystals that separate from the urine within the urinary tract. Normally, urine contains chemicals that prevent or inhibit the crystals from forming but it doesn't work for everyone & stones develop.ChaCha

Kidney stones are made of salts and minerals in the urine that stick together to form small pebbles. They can be as small as grains of sand or as large as golf balls. They may stay in your kidneys or travel out of your body through the urinary tract.
