What are the most common types of kidney stones?

The most common type of kidney stone is a calcium oxalate stone. This type happens when calcium and oxalate combine in your urine. It can happen when you have high quantities of oxalate, low amounts of calcium and aren’t drinking enough fluids.

Stones caused by uric acid are also fairly common. These come from a natural substance called purine, which is a byproduct of animal proteins (meat, chicken and fish).
