THE EFFECT OF UROGRAPHY ON RENAL FUNCTON IN PATIENTS WITH MULTIPLE MYELOMA.

Reports in the medical literature of seven patients with multiple myeloma who died of acute renal failure following intravenous urography prompted a study of 39 patients with multiple myeloma who were subjected to intravenous urography at the Cleveland Clinic from 1940 to 1959. Four developed acute renal failure and two died within three weeks. All four revealed evidence of renal damage, or insufficiency, or both prior to urography. Thirty-five patients, 15 of whom had renal damage, had no untoward reaction to intravenous urography. These observations suggest that urography is associated with a small but definite risk in patients who have multiple myeloma and renal involvement.
