METHOD FOR PREDICTION OF URINARY STONE DISEASE Russian patent published in 2012 - IPC G01N33/48 

FIELD: medicine.

SUBSTANCE: method for prediction of urinary stone disease consists in sampling urine, measuring diuresis, determining the urine calcium ions (Ca²⁺), oxalate-ions (C₂O₄ ^2-), phosphate ions (PO₄ ^3-) concentrations with additionally evaluated creatinine excretion and using the derived values by formula: wherein: K_ss is a supersaturation coefficient; C is the analysed ion concentration, mg/ml or mmole/ml; D is the diuresis, ml/day; E_cr is the creatinine excretion, mmole/day; the supersaturation coefficient is calculated, an if observing the supersaturation coefficient for C₂O₄ ^2- ions exceeding 0.1; for PO₄ ^3- ions exceeding 2.0; for Ca²⁺ ions exceeding 0.1, urinary stone disease is predicted.

EFFECT: higher accuracy of prediction of urinary stone disease.
