This

is a study (cross-sectional study of stone formers and non-stone formers) which evaluates how much of the urinary oxalate is derived from different sources. Dietary oxalate , fructose intake, vitamin C intake, and diabetes mellitus are associated with an increased urinary oxalate amount. Oral calcium intake is associated with a decreased urinary oxalate amount.
