The role of nutritional factors in the pathogenesis of recidivating nephrolithiasis is reviewed. The ingestion of liquid calcium and citrates is inversely associated with the risk of developing stones, while the ingestion of proteins, sodium, uric, and oxalates have a direct relationship. One should not restrict the ingestion of calcium in the diet, but rather one should recommended a normal or high ingestion of some 850 mg/day, and rather, one should restrict the ingestion of proteins, oxalate, and sodium, as well as keeping up a diuresis greater than 1500 cc/day.
