Answer

Inferior and superior venacavography are not generally needed in the era of modern imaging. Furthermore, preoperative imaging modalities must delineate the relationship of the tumor to the normal surrounding parenchyma to allow for safe and adequate tumor excision while preserving maximal normal renal parenchyma.
