To decrease bleeding during renal malignancy resection and to get higher resection rate as a paliative treatment for advanced renal carcinoma. 50 cases of renal carcinoma were treated with renal artery embolization from 1981 to 1996. In 96% of the cases the tumour size was larger than 7 cm in diameter. Gelatine, spring coil with antineoplastic agent were used as embolizer. After tembolization, the average bleeding of 46 cases in nephrectomy was 254 ml. Resection rate was 10%. Pain and fever varied after embolization in most cases. In 82.6% of the cases, surgery was done within 48 hours after embolization. There was no mortality and morbolity in this series. Renal artery embolization is an effective and safe procedure. It could be used as an adjuvant therapy for renal carcinoma.
