[Experience with percutaneous embolization of renal tumours (author's transl)].

We have repeated first observations of various authors of blocking angiography in 8 patients with renal tumours. Comparing angiographic findings and the surgical specimens, the success of embolization could be assessed. Control angiography 2 months following an inoperable renal tumor showed shrinking of the tumour by about one half and improvement of the general condition of the patient.
