Screening for PH1 is recommended for patients who have severe kidney stone burden and/or for those with renal failure of unknown etiology. Analysis of kidney stones may reveal that they are composed of whewellite, or pure calcium oxalate monohydrate.

In patients with PH1, renal ultrasound frequently reveals multiple bilateral radiopaque calculi (which may also be seen on CT and kidney ureter bladder radiography).
