Renal vascular pedicle injury is a severe form of renal trauma, which if not recognised and treated expediently, can lead to the loss of the kidney.
Radiographic features
CT
Contrast enhanced CT is the Imaging modality of choice. On CT it is recognised as a non-enhancing kidney. Perirenal haematoma is optional and depends on the cause of injury. If the pedicle is avulsed then there will be a large haematoma, whereas in the case of dissection no haematoma need be seen.
A devascularised kidney is consistent with a grade V renal injury.
