[Embolisation techniques for renal tumors (author's transl)].

We have performed ten embolisations in nine patients with vascular renal tumours, eight of these pre-operatively. One patient had an inoperable hypernephroma which was embolised twice. We have used gelatine sponge particles (Gelaspon). In every patient it was possible to occlude the arterial supply. There were no complications.
