RENOGRAMS. CORRELATION WITH RENAL ARTERIOGRAPHY AND INTRAVENOUS PYELOGRAPHY.

A study was carried out to determine how well the information supplied by a radioactive renogram correlates with that obtained by renal arteriography and intravenous pyelography. In 1962 35 patients at the UCLA Medical Center had all three studies. This represents a total of 70 kidneys (one kidney surgically absent). We found the radioactive renogram to be a very reliable and valuable aid in the diagnosis of kidney disease. When compared with the results of the intravenous pyelogram and aortogram, the renogram had false negative result in 11 per cent of cases, and a 14 per cent false positive result.
