overview
the four main types of kidney stones are:
- calcium stones.
most kidney stones are made of calcium compounds. conditions that cause high calcium levels in the body, such as hyperparathyroidism, increase the risk of calcium stones.
- uric acid stones.
some kidney stones are made of uric acid, a waste product in urine. you're more likely to have uric acid stones if you have:
- low urine output.
- a diet high in animal protein, such as red meat.
- an increase in how much alcohol you drink.
- gout.
- inflammatory bowel disease.
- struvite stones.
some kidney stones are struvite stones. these can be serious, because they are often large stones and may occur with an infection.
- cystine stones.
stones made of a chemical called cystine are less common. they're more likely to occur in people who have a condition that results in too much cystine in the urine (cystinuria).
