title: Comparison of urinary oxalate excretion in urolithiasis patients with and without hypercalciuria.
abstract: The relationships between urinary oxalate, calcium and magnesium were investigated in 81 patients with idiopathic calcium oxalate urolithiasis on their regular diets. A significant relationship was established between calcium and oxalate excretion in the analysis of recurrent stone-formers (n = 44, P less than 0.01), though there was no significant difference between the two in the analysis of the patients overall or in single stone-formers. This suggests that recurrent stone-formers may have some abnormality of oxalate absorption in relation to calcium absorption. The role of calcium-oxalate interaction in the gut as a cause of mild hyperoxaluria is discussed.
