Clinics in diagnostic imaging (41). Viable fractured kidney

A 21-year-old man sustained blunt injury leading to major left renal laceration (Organ Injury Scale Grade IV). The upper and lower poles of the left kidney remained perfused and excreted contrast satisfactorily. Extensive contrast extravasation and urinoma formation were noted. The patient was managed nonoperatively and blood transfusion was given. His left kidney function was preserved and he remains well at 55-month follow-up. The role of imaging in the evaluation of renal injuries and the management of patients with blunt renal trauma are discussed.
