Radiographic features
CT
Contrast enhanced CT is the Imaging modality of choice. On CT it is recognized as a non-enhaning kidney. Perirenal hematoma is optional and depends on the cause of injury. If the pedicle is avulsed then there will be a large hematoma, whereas in the case of dissection no hematoma need be seen.
A devascularised kidney is consistent with a grade V renal injury.
