The role of multi-detector computed tomography with 3D images in evaluation and grading of renal trauma

ObjectiveThe aim of this study was to assess the role of multi-detector computed tomography with 3D images in evaluation and grading of renal trauma.Patients and methodsThe study comprised 50 patients clinically suspected of having renal trauma examined with MDCT.ResultsThis retrospective study included 50 patients clinically suspected of having renal injury referred to MDCT. Males are more exposed to trauma than females. Blunt trauma represented in 40 cases (80%) and penetrating trauma in 10 cases (20%). According to AAST renal trauma was graded as follows: In blunt trauma (40 patients), 11 cases were grade I renal trauma, 8 cases were grade II, 8 cases were grade III, 7 cases were grade IV and 6 cases were grade V. In penetrating trauma (10 patients), 3 cases were grade III, 4 cases were grade IV and 3 cases were grade V. Isolated renal injury was noted in 14 cases (28%) and renal injury associated with multisystem trauma noted in 36 cases (72%).ConclusionMDCT is the modality of choice in evaluation and grading of renal trauma with high sensitivity (90–100%). CT detects site and extension of renal trauma and assesses the excretory function. CT is advantageous for the selection of best patient treatment.
