Plasma oxalate in relation to eGFR in patients with primary hyperoxaluria enteric hyperoxaluria and urinary stone disease

摘要

BACKGROUNDSince plasma oxalate (POx) concentrations increase at lower glomerular filtration rate (GFR) levels, even among those without enteric (EH) or primary hyperoxaluria (PH), the appropriate thresholds for considering a disorder of oxalate metabolism are poorly defined. The current study was completed to establish relationships between POx, GFR, and urine oxalate excretion (UOx) among patients with PH, EH, and routine urinary stone disease (USD).
