New guidelines for avoiding kidney stone recurrence.
The American College of Physicians has issued new guidelines for people who have had a kidney stone to reduce their risk of developing another stone. One recommendation is to increase fluid intake in order to pass two liters of urine a day--a simple measure that can decrease kidney stone recurrence by at least half. However, people who already drink the recommended amount of liquids, or when increased fluid intake is contraindicated (for example, if you have heart failure), should not increase their fluid intake. The guidelines also advise reducing cola intake and limiting consumption of foods containing oxalate (such as beets, rhubarb, spinach, strawberries, nuts, chocolate, tea, and wheat bran) and purines (found in asparagus, bacon, beef, oysters, shellfish, and venison, among others). The guidelines were published in the Archives of Internal Medicine, Nov. 4, 2014.
