Overweight and Obesity: Risk Factors in Calcium Oxalate Stone Disease?
Introduction. Several studies showed an association of overweight and obesity with calcium oxalate stone disease (CaOx). However, there are no sufficient data on the influence of body weight on the course of the disease and the recurrence rate. Patients and Methods. N = 100 consecutive stone formers with pure CaOx were studied. Different parameters were investigated. According to the BMI, patie...
متن کاملEffect of citrate on the urinary excretion of calcium and oxalate: relevance to calcium oxalate nephrolithiasis.
Studies in 24 recurrent oxalate stone-formers have shown that values for urinary calcium excretion for this group on at-home diets vary significantly (P less than 0.001) more than values for creatinine excretions. By placing stone-formers on controlled in-hospital diets and measuring their calcium excretions, we were able to predict probable outpatient hypercalciuria (greater than 7.5 mmol/day)...
متن کاملUrinary calcium oxalate crystal growth inhibitors.
Calcium stones occur because renal tubular fluid and urine are supersaturated with respect to calcium oxalate and phosphate. The process of stone formation includes crystal nucleation, growth, aggregation, and attachment to renal epithelia. Urine contains macromolecules that modify these processes and may protect against stone formation. Attention has focused especially on inhibitors of crystal...
متن کاملEffect of calcium intake on urinary oxalate excretion in calcium stone-forming patients.
Dietary calcium lowers the risk of nephrolithiasis due to a decreased absorption of dietary oxalate that is bound by intestinal calcium. The aim of the present study was to evaluate oxaluria in normocalciuric and hypercalciuric lithiasic patients under different calcium intake. Fifty patients (26 females and 24 males, 41 +/- 10 years old), whose 4-day dietary records revealed a regular low calc...
متن کاملRapid Communication: relative effect of urinary calcium and oxalate on saturation of calcium oxalate.
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 analysis was conducted on urinary stone risk analysis from 667 patients with predominantly calcium oxalate stones. Urinary RSR of calcium oxalate was individually calculated using Equil 2. A "theoretical" curv...
