URINARY SIDEROSIS : HEMOSIDERIN GRANULES IN THE URINE AS AN AID IN THE DIAGNOSIS OF PERNICIOUS ANEMIA, HEMOCHROMATOSIS, AND OTHER DISEASES CAUSING SIDEROSIS OF THE KIDNEY.
In diseases which bring about a siderosis of the kidney there are ordinarily present in the urinary sediment cells containing granules of hemosiderin, and often many free granules as well. The finding has proved useful in the diagnosis of hemochromatosis and will probably be of service in the recognition of pernicious anemia, and possibly some other diseases. But in this relation the fact should be emphasized that urinary siderosis, as one may term it, is the indication of a renal condition, not of a disease.
