Preventing Kidney Stones

If you've had a kidney stone, there's a 50 percent chance you'll develop another one within seven to 10 years. Luckily, there are steps you can take to reduce your chances of future stones. Find out how stones form.

At the HealthEast Kidney Stone Institute, we pay careful attention to emerging research and attempt to make our own contributions to this general body of knowledge.

There is currently no prevention program that is 100 percent effective for all people. However, by taking simple steps, it is usually possible to extend the time between stones or avoid recurrence entirely.

It is important to think of recurrent stones like any other disease such as high blood pressure or high cholesterol. For patients with severe stone disease, lifelong treatment is necessary to avoid recurrence.

Prevention tailored to you

We examine urine and blood samples: After urine and blood tests, we offer behavioral, dietary and medication recommendations that can reduce your chances of developing another stone. We then perform follow-up studies to confirm that we have had the desired effect and make further recommendations to give you the best chances of preventing future stones.

We incorporate results of population studies into our practice: We attempt to be as specific as possible in our interventions and advice. We do not ask patients to do anything unless there is good evidence to believe that it will be effective for their particular age, sex, diet, habits or urine and blood chemistry.

If you're experiencing kidney stones for the first time (and have stones made of calcium oxalate), small changes in diet and habits are often adequate to keep stones from recurring.
