Bolus nephrotomography in diagnosis of lesions of kidney.

Bolus nephrotomography was employed in the study of 100 patients with renal adenocarcinoma and 100 patients with renal cyst. A retrospective review of the vascular and nephrographic phases of this study was made. A diagnosis of renal adenocarcinoma could be made with confidence by bolus nephrotomography in 82 per cent of cases with the remaining cases indeterminate and requiring further investigation; the vascular phase was of greater diagnostic value than the nephrographic phase. A diagnosis of renal cyst could be made with confidence by bolus nephrotomography in 85 per cent of cases with the remaining cases indeterminate and requiring further investigation; the nephrographic phase was of greater diagnostic value than the vascular phase.
