title: Role of citric acid in primary hyperparathyroidism with renal lithiasis.
abstract: Nephrolithiasis is presented in 18-40% of patients with primary hyperparathyroidism. Our work suggests that citrate, an inhibitor of calcium salts, could be involved in the presence of renal lithiasis because hyperparathyroid stone formers show less citrate elimination than nonstone formers.
