Forty-seven patients with abdominal and retroperitoneal injuries were examined by computed tomography(CT). Weanalyzed the results of 47 paitents who were confirmed of abdominal injuries by operation, clinical follow up, andrepeated radiologic examinations. 1. The type of trauma was blunt in 38 patients (81%) and penerating in 9 patients (19%). 2. There were 14 splenic, 11 renal, 9 hepatic, 6 retroperitoneal, 4 pancreatic, and 3 alimentarytract injuries. 3. The patients who had been treated by conservative management were 23.4%(surgicaltreatment;76.6%). 4. The sex ratio was 4.9:1.0(male:female). 5.
