The role of multi-detector computed

Abstract

Objective: The 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 methods: The study comprised 50 patients clinically suspected of having renal trauma examined with MDCT. Results: This 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%). Conclusion: MDCT 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.
