Assessing the usefulness of delayed imaging in routine followup for renal trauma

Abstract

Purpose: Renal trauma is often managed conservatively. Repeat imaging within 48 hours of injury is recommended but to our knowledge the value of further delayed imaging is unknown. We determined the usefulness of routine followup imaging beyond 48 hours in cases of conservatively managed renal trauma. Materials and Methods: Of 377 patients who presented to our institution with renal injury in the last 8 years we identified 138 who underwent a trial of conservative treatment and repeat imaging more than 48 hours after injury. Followup imaging was categorized as routine in 108 patients (group 1) and indicated in 30 (group 2), and assessed for complications and the need for subsequent intervent..
