title: Sonographic intraperitoneal fluid in patients with pelvic fracture: two cases of traumatic intraperitoneal bladder rupture.
abstract: Two patients who presented to the Emergency Department (ED) in shock with severe pelvic fractures were evaluated for intra-abdominal injury with a focused assessment with sonography in trauma (FAST) examination. Free intraperitoneal fluid was identified in the hepato-renal recess of both patients. At laparotomy both patients were found to have extensive uroperitoneum resulting from intraperitoneal bladder rupture and no other intra-abdominal injuries. The source of shock in both cases was ultimately determined to be arterial hemorrhage from pelvic vessels. The utility of FAST examinations in the setting of major pelvic injury is relatively unstudied. Coincident injuries make the evaluation for source of hemorrhage in this subset of patients challenging. This is a report of sonographic intraperitoneal fluid in the setting of major pelvic injury and hemodynamic instability found to be uroperitoneum and not hemoperitoneum.
