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 …

Background: The study compared the effect of urinary calcium with that of oxalate on urinary
saturation [relative saturation ratio (RSR)] of calcium oxalate. Methods: A retrospective data …

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 …

Background Urinary parameters, including urine pH and citrate, are recognized as critical in
the pathophysiology of calcium-based stones. The factors contributing to variation in these …

Abstract Background and Purpose: Distinguishing calcium oxalate from uric acid stones is
critical to identify those patients who may benefit from dissolution therapy and can also help …

By means of a computerized calculation program, a simplified estimate of the ion-activity
product of calcium oxalate was derived (AP (CaOx)-index), based on the 24-h urinary …

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 …

We evaluated the crystallization of calcium oxalate (CaOx) in undiluted urine, collected 3
hours after intake of a test meal by healthy males. In two experiments in vitro, either the total …

Pure calcium oxalate is the most frequent type of idiopathic kidney stone composition.
Fourier transform infrared spectroscopy (FT-IR) allows to detect the ratio of calcium oxalate …

Objective To produce an index of lithogenic risk which identifies patients at risk of stone
recurrence and facilitates the monitoring of prophylactic treatments. Patients and methods …
