Transcatheter arterial embolization in urological tumors: the use of isobutyl-2-cyanoacrylate.

Transcatheter arterial embolization is a useful technique to manage urological tumors. Herein we describe a new embolic material (isobutyl-2-cyanoacrylate) in 5 cases of renal cancer embolization and in 1 case of bilateral hypogastric embolization for bladder cancer hemorrhage. Isobutyl-2-cyanoacrylate provides a complete, distal and irreversible embolization, making it suitable material in cancer embolization.
