The Oxalate-Tolerance-Value: A Diagnostic Tool for the Recognition of Stone Forming Patients
The thermodynamic parameters involved in the formation of calcium oxalate crystals are the concentrations of Ca2+ and C2O4, the total ionic strength of the solution and the presence of inhibitors. The kinetics of the growth of particles is governed by temperature, the presence of nuclei and inhibitors, the diffusion properties of the participating substances, (influenced by the concentration of all substances present), the agitation of the surrounding liquid and the possibility of coprecipitation1–5. Since the composition of urine with respect to some of the thermodynamic and kinetic parameters differs from one person to another and from one voiding to another, the aim of the present work was to find a method which allows comparison of the formation of crystals in different urines without disturbing the original composition of the urine.
