Predictive factors for conservative treatment failure in grade IV pediatric blunt renal trauma

The need for transfusion, and the presence of specific image features on initial CT, such as the main laceration location in the antero-medial portion of kidney, intravascular contrast extravasation, and a large perinephric hematoma, served as useful predictive factors for urological intervention in grade IV pediatric blunt renal trauma patients who were initially treated with a conservative approach. The findings indicate that early detection and appropriate intervention should be considered a priority in the conservative treatment of grade IV pediatric renal trauma with predictive factors.175Figure.
