Features and Treatment of the Inherited Primary Hyperoxalurias

The autosomal recessive inherited primary hyperoxalurias types I, II and III are caused by defects in glyoxylate metabolism that lead to the endogenous overproduction of oxalate.

Primary hyperoxaluria should be considered in any patient with a history of recurrent calcium oxalate stones, nephrocalcinosis, or both.
