Abstract
Different proportions of mixtures of whole urine and its ultrafiltrate were evaporated to 1250 mOsm/kg to study the crystal formation of calcium oxalate at pH 5.3 and calcium phosphate at pH 6.8. At both pH values there was a direct linear relationship between proportion of whole urine and crystal formation. When sodium dodecyl sulfate was added to whole urine before evaporation, calcium oxalate and calcium phosphate crystal formation were reduced to 64.3 and 53%, respectively, of the values of whole urine. Crystal formation may be promoted by polymeric uromucoid.Keywords
