All adult patients referred to Imam Hussein hospital emergency department with blunt abdominal trauma and had signs and symptoms of intra-abdominal injury were enrolled to the study and followed for one-month. Collected data analyzed with Chi-square test. Sensitivity، specificity، positive and negative predictive value of each factor was calculated.

The prevalence of three clinical factors (including’s hematuria، shock index above o. 8) and more clinical signs and symptoms at presentation were higher in patient with Intra-abdominal visceral injury than discharged patients (P<0/0001).
