Cystic fibrosis and calcium oxalate nephrolithiasis.
During the past six years, we have treated eight patients with cystic fibrosis (CF) for nephrolithiasis. In seven patients, the stones were comprised of calcium oxalate. Another six patients had calcium oxalate crystalluria. In our CF population of 140 patients, this represents a cumulative incidence of calcium oxalate nephrolithiasis of 5.7 percent and an additional 4.2 percent incidence of cr...
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 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...
متن کاملNormal calcium oxalate crystal growth inhibition in severe calcium oxalate nephrolithiasis.
Urine from mammalian kidneys is regularly supersaturated with respect to calcium oxalate monohydrate, the most common solid phase in human nephrolithiasis, and also inhibits the nucleation, growth, and aggregation of calcium oxalate crystals. Nephrolithiasis is often associated with increased supersaturation, and it is assumed that this increase overbalances the inhibition effects, causing ston...
متن کاملEffect of High Osmotic Pressure Milk Formula on Renal Calcium Oxalate Crystallization Induced by Calcium Oxalate
To study the effect of high osmotic pressure milk formula on renal calcium oxalate crystallization induced by calcium oxalate. 40 SD rats were randomly divided into four groups: NC, MC, LOM and HOM group. For model preparation, MC, LOM and HOM were treated with 1% Ethanediol in the water combined with 2% ammonium chloride (2ml/day) intragastrically administration. The rats in LOM and HOM were i...
