Description
The formation of the sparingly soluble calcium oxalate salt in the urinary tract is a major factor in urolithiasis (kidney stone formation). Oxalate in urine may arise either as an end-product of intermediary metabolism or from dietary sources.
Indications
Increased excretion may be due to oxalate rich food and absorption of oxalate in a number of gastrointestinal disorders that cause severe fat malabsorption. Decreased levels are associated with hyperglycinaemia and hyperglycinuria. Calculi may form if renal function is poor.
