[Orange juice in the prevention of calcium oxalate lithiasis].

From the assumption that prophylaxis of oxalocalcium lithiasis is feasible with an the intake of citrate-rich food, this paper presents a prospective, medium-term research in two groups of patients with a background of this type of lithiasis; the first group was treated with diet and increased fluid intake exclusively, while the second group had to follow similar dietetic measures and take also one litre of orange juice daily. Orange juice raises citraturia and pH, decreasing the rate of lithiasis formation and crystallization risk indicators for calcium phosphate. No significant differences are obtained in the number of relapse ratio reductions for the second group as compared to controls.
