[Embolization treatment of renal tumors (author's transl)].

: Embolization of renal tumors is receiving importance. This method of interventional radiology was modified for our conditions and completed by special nuclear medical diagnostic. 86 embolization procedures were carried out in 80 patients with richly vascularized renal tumours. Nephrectomy was performed in 66 of these cases. Efficacy of our embolization technique was evaluated by nuclear medicine, intraoperative morphological findings and histological results. There were no complications in our series. We have found only in one patient a rejection of isotope labelled embolic material into peripheral arteries without clinical consequence.
