The Role of Radioisotope Renal Scanning in the Assessment of Renal Disease

Experience with 500 radio-chlormerodrin renal scans has shown that the technique can detect (1) altered renal function, both focal and generalized, (2) space-occupying kidney lesions, and (3) renal size and disease in some cases in which the blood urea nitrogen is elevated and the excretory urogram inconclusive.The technique is valuable as an adjunct to the intravenous pyelogram since it may discriminate more disease than was thought to be present or may distinguish between anomalous variations in renal outline and calyceal displacement from parenchymal disease. The technique is completely harmless and there are no known contraindications to the test agent, radio-chlormerodrin.
