Do you know your kidney stone?

The unfortunate thing about kidney stones is that once you have had one there is a significant chance that you will have another one. Fortunately, there are things that you can do that may help prevent future occurrences.

One of the keys to prevention is to learn about your previous kidney stones. If you pass a stone and can save it, your doctor can have it analyzed to determine precisely what kind of stone it was. Your doctor may order blood and urine tests as well. The tests will be checking your urine volume and levels of acidity, calcium, oxalate, sodium, citrate, creatinine, and uric acid. Knowing what caused your stone will make preventing future stones more likely.
