【ABSTRACT 】 Objective To evaluate the examination metho ds of renal trauma, and application of CT in diagnosis and classification of the disease. Materials and Methods Renal trauma on CT scans wa s retrospectively analyzed in 70 patients. Results Of the total 70 cases with renal trauma, 39 ones were involved in the left kidney, 30 ones in the right kidney and only o ne in both kidneys. CT showed kidney enlargement in 30 cases (42.9%), marginal i rregularity in 15 (21.4%), subcapsular hematoma in 43 (61.4%), intra-renal hema toma in 35 (50.0%), perinephric hemorrhage in 29 (41.4%), segmental infarction i n 8 (11.4%), minor parenchymal contusion in 4 (5.7%), laceration or tear in 41 ( 58.6%), shattered kidney in 5 (7.1%), disruption or occlusion of the main renal artery in 2 (2.9%). In addition, combined liver or spleen injuries were discover ed in several cases. Conclusion Plain and enhanced CT scans proved to be the best method of choice in assessing renal trauma, with an accuracy rate of diagnosis (100%) and classification (92.7%). Accurate CT classification of the disease may play an important role for clinical management strategy.
