Oxalate Clearances in Calcium Oxalate Stone Forming Patients
1994A primary defect in membrane transport of oxalate across red blood cells has been reported in patients with idiopathic renal lithiasis (IRL); corrected by thiazide diuretics (TZ). To assess whether this is reflected in abnormal renal tubular handling of oxalate, we evaluated renal handling of oxalate in normals, patients with RL and primary hyper ...

Effects of an oxalate load on urinary oxalate excretion in calcium stone formers
Journal of Renal Nutrition, 2003To investigate the oxalate intake and the effect of an oxalate load on urinary oxalate excretion in calcium stone-forming (CSF) patients.Prospective study.University-affiliated outpatient Renal Lithiasis Unit.Seventy (70) CSF and 41 healthy subjects (HS) collected a 24-hour urine sample and were submitted to a 3-day dietary record to determine mean ...

Increased rates of either oxalate absorption or endogenous oxalate synthesis can contribute to hyperoxaluria, a primary risk factor for the formation of calcium oxalate-containing kidney stones. This study involves a comparative assessment of oxalate absorption and endogenous oxalate synthesis in subpopulations of stone formers (SFs) and non-stone ...

Intestinal Oxalate Absorption in Calcium Oxalate Stone Disease
1981Several laboratories have reported a slight but significant increase in urinary oxalate excretion in patients with calcium oxalate stone disease1–4. The mechanism responsible for this increased oxalate excretion remains largely unknown. Zarembski and Hodgkinson5, and Robertson et al.1 reported that patients with calcium oxalate stones had a greater ...

Calcium Oxalate Stone Morphology: Fine Tuning our Therapeutic Distinctions
Journal of Urology, 1996We determined specific radiographic morphological patterns of crystallographically analyzed pure and mixed calcium oxalate dihydrate and calcium oxalate monohydrate urinary calculi.A total of 86 greater than 1 cm. calculi crystallographically analyzed as pure calcium oxalate monohydrate, calcium oxalate dihydrate or admixtures of the 2 types was ...

Stone Recurrence Predictive Score (SRPS) for Patients with Calcium Oxalate Stones
Journal of Urology, 2003We developed a convenient, self-administered 8-item stone recurrence predictive score (SRPS) to predict the recurrence of calcium oxalate stones.An 8-item SRPS to predict stone recurrence was developed based on general patient data, including age, sex, urine volume, smoking, wine drinking, family history, stone number and history of gouty arthritis ...

Lipids of Calcium-Oxalate Urinary Stones
1989It is generally agreed that crystal nucleation during urolithiasis is heterogeneous. However, the nature of these nucleators is still unknown. Membrane lipids have been histochemically and biochemically demonstrated at physiological as well as pathological calcification sites (1) and have been implicated in nucleation of crystals in a number of bio ...

Urinary oxalate is a biomarker for calcium oxalate kidney stone disease; however, its assay is insensitive and nonspecific. Calcium oxalate monohydrate (COM) binding protein (45 kDa) is a promoter of calcium oxalate kidney disease, which is markedly upregulated by oxalate induced oxidative stress.

Simulation of calcium oxalate stone in vitro
Science in China Series B, 2003Crystallization of calcium oxalate is studied mainly in the diluted healthy urine using scanning electron microscopy (SEM), and is compared with the crystallization in the diluted pathological urine. It suggests that the average sizes of calcium oxalate crystals are not in direct proportion to the concentrations of Ca2+ and Ox2- ions.

Management of calcium oxalate stones.
Clinical excellence for nurse practitioners : the international journal of NPACE, 2002This article discusses the incidence and prevalence of calcium oxalate renal stones. Etiology and risk factors for all renal stone formation are reviewed. The evaluation, diagnostic procedures, and management for new and recurrent stone formation are detailed.
