[Roentgenoendovascular occlusion in patients with cancer of the kidneys].

Roentgenendovascular occlusion of the renal artery was used in 116 patients with renal carcinoma, in 70 of them the embolization was performed as a preoperative measure 3-12 days (7 days at an average) before nephrectomy. Embolization was also performed in 46 patients with spreaded renal carcinoma with metastases or with somatic diseases preventing surgical interventions. The roentgenendovascular occlusion reduced the time of operation and blood loss in nephrectomy, especially in patients with great hypervascularized tumors. In patients with inoperable renal carcinoma embolization was followed by arrest of hematuria, relief of pain and prevented progress of the disease.
