Sodium-Chloride-Dependent Oxalate Absorption in the Human Intestine

High urinary oxalate excretion is one of the important determinants of stone formation in idiopathic calcium oxalate (CaOx) stone formers. High oxalate excretion is often observed in CaOx stone formers. In such patients, foods containing high oxalate levels (such as rhubarb, spinach, chocolate) should be restricted.
