What are the different types of kidney stones?
There are many different types of kidney stones. The vast majority of stones are composed of calcium. The most common types of stones are calcium oxalate (70%), calcium phosphate (5-10%), struvite (10%), uric acid (10%) and cystine (1%). It is not uncommon for a single stone to be made of more than one of these types. When this occurs, the stone is commonly referred to as a mixed stone. Less common types of kidney stones include Xanthine, DHA and crixivan stones.
