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

Background: We studied the effect of potential risk factors of urinary calcium oxalate
saturation on calcium oxalate stone formation. Methods: Using the Equil2 program, the DG …

Our aim was to investigate the validity of osmolality from 24-h urine collection in examining
the risk for calcium-oxalate (CaOx) kidney stone formation in patients with recurrent …

Objective: The aim of this study was to determine the usefulness of the morning calcium
oxalate crystalluria in detecting stone formers particularly prone to recurrence. Methods …

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 …

Serial crystalluria determination and the risk of recurrence in calcium stone formers.
Background Urinary crystal precipitation is the necessary initial step in kidney stone …

PURPOSE: Epidemiological studies have reported that high calcium diet protects against
kidney stone formation in normal subjects. This metabolic study was designed to elucidate …

Purpose: We determined what metabolic features of the 24-hour urine predict calcium
oxalate dihydrate in kidney stones. Prior studies have suggested that low urine magnesium …

PURPOSE: Recent studies suggest that a high calcium diet protects against calcium oxalate
stone formation. We compared the effect of high and low calcium diets on urinary saturation …

Background The diagnosis and follow-up of stone forming patients is usually performed by
analysis of 24-h urine samples. However, crystallization risk varies throughout the day …
