Abstract

Background: Renal injury is the third most common solid organ injury in blunt abdominal trauma, In this study we aimed to demonstrate different traumatic lesions of the kidneys using multi-detector CT, and its use in staging and management of lesions. Methods: The study included 40 patients with history of abdominal trauma & signs and symptoms of renal injury. All patients were referred to the CT unit–Radiology department–AlAhrar teaching hospital, Zagazig, Sharkia governorate. Patients was subjected to Full clinical assessment, Complete history taking, Radiological assessment by FAST (Focused Assessment with Sonography in Trauma), and Contrast-enhanced multiphasic renal CT study. Results: This study included 40 patients, They were 28 males and 12 females; their ages ranged from 3 to 66 years. FAST examination show that intra-peritoneal free fluid was the commonest finding (95.0%) among the studied group while sub-capsular hematoma, de-bulbed kidney, contusion and deep laceration present among (17.5%, 10.0%, 5.0% and 2.5%) of the studied group respectively. CT examination show that intra-peritoneal free fluid was the commonest finding (47.5%) among the studied group followed by deep laceration reaching collecting system which present among (37.5%), shuttered kidney (30.0%) and deep laceration (17.5%) then sub-capsular hematoma, renal pedicle avulsion, contusion and superficial laceration each of them present among (5%) of the studied group. There was highly significant excellent agreement between MDCT and follow up regarding grading of renal injuries. Conclusion: ultrasound and computed tomography are the most relied on modalities for assessing abdominal trauma and predicting need for laparotomy.
