What is (are) What I need to know about Kidney Stones ?
Doctors have found four main types of kidney stones:
                
- The most common types of stones contain calcium. Calcium is a normal part of a healthy diet. Calcium that is not used by the bones and muscles goes to the kidneys. In most people, the kidneys flush out the extra calcium with the rest of the urine. People who have calcium stones keep the calcium in their kidneys. The calcium that stays behind joins with other waste products to form a stone. People can have calcium oxalate and calcium phosphate stones. Calcium oxalate stones are more common.  - A uric acid stone may form when the urine contains too much acid. People who eat a lot of meat, fish, and shellfish may get uric acid stones.  - A struvite stone may form after you have a kidney infection.  - Cystine stones result from a genetic disorder, meaning a problem passed from parent to child. The disorder causes cystine to leak through the kidneys and into the urine.
