Imaging features of primary hyperoxaluria.

Primary hyperoxaluria (PH) is a group of autosomal recessive diseases that affect the metabolism of glyoxalate and oxalate. As a result of the enzymatic deficiency, there is overproduction and urinary excretion of oxalate with progressive renal damage and subsequent deposition of oxalate salts in various tissues. The definitive treatment in cases of end-stage kidney disease is a combined liver and kidney transplant.
