Recommend Calcium to Help Prevent Kidney Stones

Calcium stones...especially calcium oxalate stones...account for about 80% of kidney stones. And about 50% of patients with a first kidney stone will have another within 5 years without any treatment.

Emphasize dietary changes first. Suggest aiming for twelve 240-mL glasses of liquid/day...or enough to produce ≥ 2 L/day of urine.
