COMPUTED TOMOGRAPHY AND ULTRASOUND IMAGE FEATURES IN RENAL TRAUMA

Abstract

Objective:The purpose of this study was to describe the ultrasound and computed tomography (CT) image features, study the correlation and value between ultrasound and CT in renal trauma classification. Materials and Methods: With cross-sectional studies, we conducted at 52 renal trauma diseases had had ultrasound and CT at Hue Central Hospital and Hue University Hospital from 01/2012 to 07/2013. Results:ultrasound detected 44/52 renal trauma cases and arranged in AAST grade classification. The image features include: ultrasound, CT, alternately: renal contusion 82.7%, 86.52%, renal laceration 65.38%, 76.9%, perirenal hematoma 76.9%, 88.5%, subcapsular hematoma 21.2%, 25%, shattered kidney 3.84%, 7.7%, injuries involving the main renal artery or vein, 7.7%, 15.4%, ureteropelvic junction avulsions 3.84%, 7.7%. Most of renal trauma is 1 and 2 grades with scale on ultrasound 63.63%, CT scanner 54.54%.There had a moderately positive correlation between ultrasound and CT scanner with renal trauma classification. Conclusions: In renal trauma, ultrasound is the first imaging technique, was indicated. But CT scanner is always the most imaging technique for full analyses and exactness. Key words: Renal trauma, ultrasound, CT scanner.
