Arterial Embolization for the Treatment of Renal Masses and Traumatic Renal Injuries.

Renal artery embolization (RAE) for a variety of indications has been performed for several decades. RAE techniques have been refined over time for clinical efficacy and a more favorable safety profile. Owing to improved catheters, embolic agents for precise delivery, and clinical experience, RAE is increasingly used as an adjunct to, or as the preferred alternative to surgical interventions. The indications for RAE are expanding for many urologic and medical conditions. In this article, we focus on the role and technical aspects of RAE in the treatment of renal masses and traumatic renal injuries.
