High-dose bolus urography was evaluated in 38 patients with severe renal failure. Iothalamate meglumine (Conray 60) (2 ml/kg of body weight) was injected within one minute and nephrotomograms were taken for 30 minutes, with delayed films until 24 hours. Immediate nephrograms were obtained in all cases. The collecting systems, seen in 29 cases, were dilated in three. In the rest, obstruction could be ruled out by a combination of roentgenographic criteria. No untoward reactions occurred, and all the required information was obtained within 30 minutes. The results were superior to plain nephrotomography or infusion pyelography. We conclude that bolus nephrotomography is the procedure of choice in the investigation of severe renal failure.
