[Preoperative or palliative embolization of renal tumors].

This study evaluates our experience of renal preoperative or palliative embolization in 72 patients with a localized renal carcinoma or a metastatic disease. Angio-infarction of a renal malignant neoplasm is a helpful procedure to reduce the tumoral vascularization before an operation and to palliate symptoms and paraneoplastic syndromes of a metastatic disease with a very low morbidity.
