The risk of calcium oxalate crystallization was analyzed in terms of the increase in oxalate concentration required for a standardized precipitation of crystals of calcium oxalate. The degree of urine dilution was determined with a new instrument (urimho) designed for measuring the concentration, in ...
What does it mean to have calcium oxalate crystals in urine? It could indicate that the patient is suffering from nephrolithiasis and acute renal failure. Although, calcium oxalate crystals is present in the urine of people with high dietary oxalate ingestion and too much intake of vitamin C. I...

Ten of these specimens, designated type A, spontaneously precipitated calcium oxalate crystals when the median urate concentration was increased from 3.13 to 7.33 mmol/liter by the addition of a saturated solution of sodium urate. In the remaining more dilute urines, which were designated type B, ...
The total amount of CaOx crystals (expressed as calcium oxalate dihydrate crystals (COD)+oxalate monohydrate crystals (COM)area/total area × 100)was on average 13.2% in U urine, 70.7% in CF urine and 11.1% in CFU urine (CF>U and CFU, U=CFU); the relative prevalence of COD and COM...
Calcium oxalate dihydrate formation in urine. Factors that promote the formation of calcium oxalate dihydrate (COD) in urine were investigated. Crystals resulting from the incubation of 25-ml aliquots of the solution to be tested and 1 ml of 0.05M ammonium oxalate were examined by infrared ...

Our present study thus addressed effects of differential urine pH (4.0–8.0) on calcium oxalate (CaOx) crystallization, crystal-cell adhesion, crystal internalization into renal tubular cells, and binding of apical membrane proteins to the crystals. Microscopic examination revealed that CaOx monohydrate...
Removal of macromolecules with M r greater than 10000 had no discernible effect on the detectable nucleation of calcium oxalate crystals from undiluted human urine, but promoted the deposition of crystalline material and markedly increased the degree of aggregation of the precipitated crystals. Calcium ...
