Renal embolization.

Recent developments in endovascular radiological techniques and devices make embolization as a major therapeutic option in many renal vascular or neoplastic diseases, before surgery. These techniques show a very good efficacy with a low morbidity and a better renal tolerance. Indications of embolization in nephrology are post-biopsy arteriovenous fistulas, renal graft intolerance, functional exclusion and polycystic kidney disease before transplantation.
