types of stones or calculi
Struvite stones. Some kidney stones are struvite stones. They can also be called infection stones if they occur with kidney or urinary tract infections (UTIs) . These types of kidney stones sometimes are also called staghorn calculi if they grow large enough.
With bladder stones, the most common type is a uric acid stone. Less common types of bladder stones include calcium oxalate, calcium phosphate, ammonium urate, cysteine, or magnesium ammonium phosphate stones.
Calcium stones are the most common. They can be made of calcium oxalate (most common), phosphate, or maleate. Eating fewer oxalate-rich foods can reduce your risk of developing this type of stone. High-oxalate foods include potato chips, peanuts, chocolate, beets, and spinach.
