Delayed presentation of grade-IV renal injury post blunt trauma

High-grade renal injuries are relatively uncommon in blunt trauma. They typically occur in the context of multisystem injuries. When present, these renal injuries are usually identified at the time of hospital presentation. Here, we present a case of delayed presentation of American Association for the Surgery of Trauma (AAST) grade-IV renal injury in a 61-year-old female who sustained multisystem injuries during a high-speed motor vehicle accident. To our knowledge, this is the first report case of delayed presentation of grade-IV renal injury. This case highlights the importance of serial examination and repeated imaging in complex trauma patients.
