title: Ureteral entrapment injury in blunt pelvic trauma: a case report.
abstract: An unusual ureteral injury occurred during blunt pelvic trauma in a 6-year-old boy. Crush injury opened the sacroiliac joint, and the ureter was trapped and obstructed during realignment of the joint. Combined retrograde and anterograde pyelography accurately localized the injury and surgical repair restored renal function, despite total ureteral obstruction lasting more than 3 months. The mechanism, diagnosis and treatment of this injury are discussed. Vascular and ureteral injuries must be ruled out carefully when treating blunt renal injuries conservatively.
