[Angiography in the diagnosis of kidney neoplasms]

After assessing the usefulness of the various X-ray techniques in the diagnosis and staging of renal neoplasias, an approach based initially on non-invasive studies like urography, ecotomography and TAC and then on invasive techniques is considered. Adequate preoperative angiography of renal neoplasias is considered very useful and the diagnostic features of angiographical investigations are described in terms of staging and therapeutic applications in possible endo-arterial embolism.
