[Diet and nutrition in nephrolitiasis].
Nephrolitiasis is a frequent metabolic disease, with a high rate of recurrences. Epidemiological studies reveal that about 80% of all kidney stones are composed of calcium salts (75% calcium oxalate), while about 5% are pure uric acid. Urolithiasis is a multifactorial disease with several underlying disorders of metabolism: that is why diet is an important treatment, especially in the prevention of recurrences. Nutritional intervention is based on a high water intake, physiological calcium intake, modest sodium and animal protein restriction and vitamin C intake <2 gr daily. In case of diagnosed disorders of specific metabolic pathways, a low oxalate, low purine-diet should be advisable.
