Ruptura isolada da pelve renal secundária ao trauma abdominal contuso / Isolated disruption of the renal pelvis by blunt trauma

ABSTRACT

Blunt rupture of the renal pelvis is a exceedingly rare injury. Hematuria is absent in one-third of cases. Such injuries are usually caused by desacceleration forces. Despite improved imaging techniques, diagnosis of this injuries is frequently delayed. Diagnosis is suggested by the presence of massive medial extravasation of contrast material at excretory urography or computed tomography. Surgical treatment consists in pyeloplasty or pyeloraphy with stent placement (double J) or nephrostomy.
