[Urinary magnesium excretion in nephrolithiasis].
Magnesium urine excretion and its correlation with calcium urine excretion were studied in 152 patients with nephrolithiasis by atomic-absorption spectrophotometry. In 14.5% of the patients with unilateral nephrolithiasis and in the 25.6% of the patients with bilateral nephrolithiasis the magnesium urine excretion was lowered. Following calcium loading the magnesiumuria in healthy persons was reliably and positively influenced while in the patients with nephrolithiasis with initial lowered magnesium excretion there was an insignificant increase. The ration MgU/CaU is of special importance for the evaluation of the lithogenic risk. The determination of the Ca-Mg interrelation is obligatory for every patient with nephrolithiasis because of its great practical importance for the treatment of these patients.
