[Laboratory methods of predicting primary and recurrent nephrolithiasis].
Concentrations of Na, K, Ca ions, oxalic and uric acids, total Ca, P as well as urease activity, the ability to form crystals, speed of crystallization, crystal chemical composition, pH stability were evaluated in the urine from 40 urolithiasis patients and 40 patients with recurrent nephroliths. It was found that fast or moderate crystallization, high urease activity and ability to form crystals, unstable urine pH indicate a high risk of both primary and recurrent nephrolith formation.
