Multidetector computed tomography in the diagnosis and management of renal trauma

Renal injuries fall within the broad and complex subject of retroperitoneal trauma. Although their computed tomography (CT) features have been known for a while, the timing, diagnostic approach and management are still debated. In addition, some areas of uncertainty remain regarding timing, indications and imaging modalities to be used in the follow-up of these patients. The purpose of this paper is to review the impact of CT on the management of renal trauma, stressing the importance of this technique and the role of the radiologist in the timing of decisions. Finally, we discuss the diagnostic approach to the follow-up of renal trauma.
