Abstract
Patients (23) with renal functional deterioration after i.v. pyelography were studied; 16 were nondiabetic. Nondiabetic patients at risk are often elderly and have pre-existing renal disease. The course of acute renal failure is fairly characteristic; most patients recover, but some do not. Estimates suggest that the syndrome is not uncommon in susceptible nondiabetic subjects. Pyelography cannot be considered absolutely safe for this group, and alternative diagnostic procedures or caution with contrast dosage and patient preparation may be wise.
