Figure 9a. Type II injury. (a) CT scan shows extravasated contrast material (arrows) in the urinary tract above the UGD. The balloon of a Foley catheter (b) is seen in the prostatic urethra. (b) RUG image obtained in another patient shows extravasated contrast material (arrows) above the UGD. The contrast material has tracked into the prevesical space in the pelvis (arrowheads); this finding is characteristic of a type II injury.
