Solubility of calcium oxalate in human urine, simulated urine, and water.
The main factors that determine the amount of oxalate that can be held in solution in urine were found to be the ionic strength and the calcium and magnesium concentrations. Citrate seemed to be relatively unimportant at normal urine pH. Urea, pyrophosphate, chondroitin-4-sulphate, and chondroitin-6-sulphate were without effect at the concentrations normally found in urine.
