answer:Not once you’ve got them, really. They need to get peed out, or if they’re too big, pulverized. As for prevention, yes. Collect your stone and take it to a nephrologist for analysis. If it’s a calcium oxalate stone (the most common type) you can prevent getting another by eating a low oxalate diet. Oxalate is not produced in the body naturally, so you can entirely control its presence in your body through your diet.
