Lateral radiograph obtained during a contrast cystourethrogram immediately after coil and cyanoacrylate embolization. A urinary catheter can be visualized in the perineal urethra and contrast is being injected. The coils can be visualized at the origin of the accessory urethra and no contrast is filling the accessory urethra during the contrast cystourethrogram. In this image, the contrast present in the accessory urethra was introduced during the original contrast cystourethrogram before embolization and has been incorporated into the cyanoacrylate within the accessory urethra.
