Renal disease occurs frequently along with diseases of the liver. In autopsy material of patients with liver cirrhosis, half of the patients have morphological signs of secondary type IgA nephropathy. In this paper we report on the renal changes observed in patients with diseases of the liver, such as hepatic glomerulosclerosis, secondary IgA nephropathy, glomerulonephritis with viral hepatitis, systemic disease with hepatitis (mixed cryoglobulinemia and polyarteritis nodosa) with renal affection, renal changes after liver transplantation and the hepatorenal syndrome. The morphological changes of the kidney are emphasized.
