Bile Cast Nephropathy in Patients with Acute Kidney Injury Due to Hepatorenal Syndrome: A Postmortem Kidney Biopsy Study

Background and Aims: The role of bile cast nephropathy (BCN) in pathogenesis of hepatorenal syndrome (HRS) in decompensated cirrhosis and acute on chronic liver failure (ACLF) is unknown. This study aimed to determine the frequency of BCN detected on postmortem renal biopsy among patients with decompensated cirrhosis and ACLF who had been admitted with acute kidney injury due to HRS (HRA-AKI) and expired during that hospitalization.
