Kidney Stone Guideline Offers Recommendations on Prevention and Treatment

A new guideline issued by the American College of Physicians recommends increased fluid intake spread throughout the day to achieve at least 2 L of urine per day to prevent recurrent kidney stones. It also recommends treatment with a thiazide diuretic, citrate, or allopurinol to prevent recurrent kidney stones in patients with active disease in which increased fluid intake fails to reduce the formation of stones. The guideline is published in the Annals of Internal Medicine.
