[Unilateral absence of excretion in urography after external injury]

Abstract

We communicate a case of unilateral renal non visualization in the pyelogram after an external trauma, due to traumatic occlusion of the main renal artery. The etiology and pathogenesis are reviewed and the frequent associated injuries of other abdominal organs are emphasized. The Pyelogram, used as a screening technique, is useful, though in these situations, CT-scan and rarely angiography are the methods of choice in the evaluation of parenchymal and vascular injures of the kidneys, as well as in evaluating other abdominal organs. El surgical treatment is not necessary early, nephrectomy of the ischemic kidney may be postponed depending on the evolution of the patient.
