[Traumatic injuries of the distal ureter in pelvic fractures].

Ureteral injuries due to external blunt violence are quite rare. Less than 40% of these injuries are diagnosed in the first 24 hours. The authors described 2 cases of traumatic injuries of the lower ureter due to pelvic fractures. In both patients the injuries are caused by a bony spicule of the fractured acetabulum. If acetabular fracture occurs possible ureteral injury should be suspected and excluded by an intravenous urogram.
