Imaging in renal trauma

Figure 6 Grade IV injury. Laceration involving the pelvicalyceal system (PCS). Contrast enhanced computed tomography (CECT) images of a 7-year-old male who had a fall from height with resulting blunt trauma to the abdomen. A: Axial; B: Sagittal section showing deep laceration in lower pole of the right kidney extending up to the renal hilum; C: Sagittal section; D: Thick coronal maximum intensity projection image of the excretory phase shows leakage of excreted opacified urine (arrow) through the laceration suggesting PCS injury with resultant urinoma (a) formation around lower pole of right kidney.
