They look like large spheroids with radial striations. Calcium carbonate in smaller size has a round to ovoid shape. The color is usually colorless to yellow brown. There will be a significant change in urine color. The urine is brownish tinge, especially if the calcium carbonate crystals go o...

Urine sample were collected from 20 men with no history of urolithiasis and the intact GAGs removed by 10 kDa ultrafiltration. 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...
The polymer was imprinted with either calcium oxalate monohydrate (COM) or dihydrate (COD) template crystals. These were washed out of the polymer, which was then immersed in various test solutions. The test solutions were an aqueous solution of calcium chloride and sodium oxalate, artificial ...
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 spectrophotometry. With reference spectra of known ...
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...
Kidney stones are mainly composed of inorganic crystals such as calcium oxalate (CaOxa). At present, kidney stones can be detected only after their formation, which causes great suffering for patients. If kidney stones can be detected prior to their formation, they can be effectively prevented, ...
