KIDNEY STONES: PREVENTION AND TREATMENT

Treat the Patient Not Just the Stones

We cannot ignore the excellent body of work that has disclosed undeniable associations between stone forming and significant bone, hypertensive, and kidney disease. Multiple investigators have found that having stones predicts higher risks we need to mitigate through treatment that can both reduce stone forming and protect against fractures, high blood pressure, and kidney disease. The main stay of such treatment is the kidney stone diet. It so much resembles the diet recommended for all Americans I cannot but say every stone formers should adopt it. While incomplete treatments like very high fluid intake, or perhaps rigorous low oxalate diet may stave off stones, they fail to address the range of diseases to which stone formers are more prone than otherwise normal people. There is no sense to such incomplete measures when proper diet can do so much more.

Why Delay Prevention

As I thought about modern prevention of the common stone using diet and fluids, I asked myself when treatment should start. Many say why bother unless a person formes multiple stones – as if to qualify as an established stone producer. I think that is not right. My review of published trials shows that the outcome for treated patients dims as they have had more stones before treatment began. Moreover, the ideal diet for stone prevention matches exactly with the ideal diet for the US population. So why wait at all about diet? As for fluids, the same. Why wait. Even more, why wait for the first stone. Stones are very familial. If you have them, your family members are at increased risk. I will not quibble about how much more risk, because I do not care. If the diet is the one we are all supposed to eat, why not eat it now if you have a relative with stones? As for attention to hydration, the same. That impatience led to this article.
