Abstract

Although the various metabolic abnormalities underlying Ca stone disease have been extensively studied, none of these except abnormalities in 24-h urine samples appear to be of any practical significance as predictors of stone risk (1–3). This is an issue of practical relevance. Previous studies have shown that urinary Ca excretion rises after glucose ingestion (4, 5), a fact that could account for hypercalciuria in some Ca stone formers who are overweight. In the present study, we examined increases in urinary Ca excretion following glucose ingestion in order to determine if there was some relation between these incidents in the evolution of Ca stone disease. This was a retrospective study and could, therefore, constitute a reliable predictive index for Ca stone recurrence.
