[Results of selective kidney DSA in suspicious computerized tomography findings--retrospective evaluation of 122 cases].

The superiority of computer tomography in the detection and staging of renal malignomas has been proven in numerous studies. In this retrospective analysis, the significance of the pre-surgically still widely and routinely performed, selective kidney angiography was investigated. The written computer tomographical and angiographic findings of 122 patients were classified according to malignancy stage urgency. They were then compared to progression, and surgical finding respectively. Angiography had the greatest influence on the therapeutic procedure in those patients having only a slight computer-tomographical suspicion of tumor. An operation was waived by 12 patients. A small hypernephroma (pT 2 showing typical tumor vessels was found in two patients. Inoperability excepted, a surgical denudation was performed in all patients with computer tomographical tumor typical, or suspicious finding, irrespective of the angiographic result. The diagnosis was surgically confirmed in all patients having a tumor-specific angiogram. Yet besides benign tumors, 4 hypernephromas and 5 other malignomas were found in those patients showing an angiographically classified, vessel-free formation.
