To better define the relative role of metabolic factors in the recurrence of stone formation, we
studied the 24-hour urinary excretion of calcium (uCa), citrate (uCit), oxalic acid (uOx) and …

In idiopathic recurrent urolithiasis (IRCU) calcium oxalate and calcium phosphate are
components of stones. It is not sufficiently known whether in urine the nucleation (liquid-solid …

Nephrolithiasis is associated with an increased risk of chronic kidney disease, and its
incidence varies with age. However, little is known on the combined impact of aging and …

The aim of this study is to investigate the effects of dietary factors on 24-hour urine
parameters in patients with idiopathic recurrent calcium oxalate stones. A total of 108 of …

In calcium renal stones, calcium oxalate and calcium phosphate in various crystal forms and
states of hydration can be identified. Calcium oxalate monohydrate (COM) or whewellite and …

hour urinary citrate excretion was measured in 176 calcium oxalate stone formers and 100
normal controls. A statistically significant difference (p< 0.03) could be found between the …

PURPOSE: Dietary oxalate may contribute up to 50% to 80% of the oxalate excreted in
urine. We studied the urinary response to an oral oxalate load in male and female idiopathic …

Purpose: Since the incidence of renal calculi in the South African black population is
extremely rare while in white subjects it occurs at the same rate as elsewhere in the western …

In 222 random spot urine specimens, the calcium concentration and calcium oxalate
saturation {DG (CaOx)} were significantly higher among stone formers than among non …

It has been speculated that calcium supplement in subjects with low oxalate intake might
increase the risk of calcium stone formation due to an increase in calcium absorption without …
