Changes in urinary nanocrystallites in calcium oxalate stone formers before and after potassium citrate intake
The property changes of urinary nanocrystallites in 13 patients with calcium oxalate (CaOx) stones were studied before and after ingestion of potassium citrate (K3cit), a therapeutic drug for stones. The analytical techniques included nanoparticle size analysis, transmission electron microscopy, X-ray diffraction, and Fourier-transform infrared spectroscopy. The studied properties included the ...
متن کاملTwo-carbon oxalogenesis compared in recurrent calcium oxalate stone formers and normal subjects.
We used a xylitol load to test the two-carbon pathway to oxalate production in humans. Use of this pentose sugar caused a fourfold increase in glycolate excretion, indicating its suitability as a dynamic function test of two-carbon metabolism. However, despite this increase in glycolate excretion in 10 recurrent stone formers and six normal subjects, there was no concomitant increase in oxalate...
متن کاملCrystal-associated nephropathy in patients with brushite nephrolithiasis.
BACKGROUND We have biopsied the renal cortex and papillae of patients who form brushite renal stones asking if this unusual stone type is associated with specific tissue changes. We contrasted these with biopsies of 15 calcium oxalate stone formers, three stone formers with intestinal bypass, and four normal subjects. METHODS We studied all ten brushite stone formers treated with percutaneous...
متن کاملThiazides reduce brushite, but not calcium oxalate, supersaturation, and stone formation in genetic hypercalciuric stone-forming rats.
Over 59 generations, a strain of rats has been inbred to maximize urine calcium excretion. The rats now excrete eight to 10 times as much calcium as controls. These rats uniformly form calcium phosphate (apatite) kidney stones and have been termed genetic hypercalciuric stone-forming (GHS) rats. The addition of a common amino acid and oxalate precursor, hydroxyproline, to the diet of the GHS ra...
متن کاملDistinguishing characteristics of idiopathic calcium oxalate kidney stone formers with low amounts of Randall's plaque.
BACKGROUND Overgrowth of calcium oxalate on Randall's plaque is a mechanism of stone formation among idiopathic calcium oxalate stone-formers (ICSFs). It is less clear how stones form when there is little or no plaque. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Participants were a consecutive cohort of ICSFs who underwent percutaneous nephroscopic papillary mapping in the kidney or kidneys...
