Restricted Calcium Diet and Calcium Oxalate Urolithiasis
Urinary excretion of oxalate plays an important role in the formation of calcium oxalate crystals1 and stones2. Elevated oxaluria has been observed in stone-forming patients with hypercalciuria3,4. This hyperoxaluria might be explained by an increase in the intestinal absorption of calcium leading to a decrease in the intestinal concentration of calcium thereby reducing the complexation of calcium with oxalate and favouring the intestinal absorption of oxalate5.
