Kidney stones can have different chemical compositions. A majority of kidney stones are of the following three types. These include stones that contain calcium compounds, stones consisting of a chemical compound called Struvite and stones that are made up of uric acid.

The type of kidney stones that affects the most number of people with kidney stones is made of calcium compounds. These stones could be made of calcium oxalate by itself or can contain calcium oxalate with calcium phosphate that leads to the formation of minerals called apatite and brushite. Over 80% people with kidney stones in the US and around 70 - 75% of kidney stone patients around the world have stones containing calcium compounds.
