Kidney in danger: CT findings of blunt and penetrating renal trauma.

Approximately 10% of all significant blunt abdominal traumatic injuries manifest with renal injury, although it is usually minor. However, renal imaging is indicated in cases of gross hematuria, penetrating trauma with gross or microscopic hematuria, and blunt trauma and shock with gross or microscopic hematuria. Contrast material-enhanced computed tomography (CT) is the imaging modality of choice in the evaluation and management of renal trauma.
