FABP1 and acute kidney injury: They also found urinary Cr-corrected NGAL (NGAL/Cr) to be thebest predictive marker for AKI [23].Because AKI occurred only in their thoracic EVAR (TEVAR) group, the TEVAR proceduredid not appear to affect renal blood flow differently from the EVAR procedure.Because our study used EVAR, we postulated that the cutoff urinary L-FABP levelwould be lower in the Ueta et al. study than in our study.
