Renal venography in the evaluation of poorly vascularized neoplasms of the kidney.

] 4OST primary malignant renal neolvi plasms are easily diagnosed by selective magnification renal arteniography. In some cases, however, poorly vascularized infiltrating tumors may have subtle nondiagnostic findings at arteniography, while selective renal venographv may reveal the characteristic malignant nature of these elusive tumors. This report describes the application ofselective renal venography in evaluating such tumors.
