Detection of intrarenal venous invasions of malignant renal neoplasms by retrograde renal venography.
The purpose of this study was to detect intrarenal venous invasion of malignant renal neoplasms not detected by other methods, with retrograde renal venography using a renal artery obstructing balloon. By this method, we studied 21 patients with malignant renal neoplasms, and clearly demonstrated the intrarenal branches up to the interlobar veins in all of these cases without any complications. This method detected small intrarenal venous lesions in three cases of renal cell carcinoma.
