Traumatic rupture of a renal pelvis obstructed at the ureteropelvic junction: case report

Blunt abdominal trauma is a rare cause of injury to the upper ureter and renal pelvis. However, a pre-existing renal abnormality predisposes the kidney sustaining even minor trauma to serious injury. A case of a ruptured renal pelvis congenitally obstructed at the ureteropelvic junction following relatively minor trauma is presented, the literature reviewed, and susceptibility factors for traumatically induced hydronephrotic rupture discussed.
