Rupture of the normal renal pelvis after blunt abdominal trauma

Blunt abdominal trauma with isolated rupture of the normal renal pelvis is an extremely rare clinical entity. The correct preoperative diagnosis may be difficult and challenging because of the insidious onset, lack of blood loss, and frequently, lack of urinary symptoms. Intraoperative inspection of the collecting system is the most accurate method to fully define an extent of injury.
