Posttraumatic functional exclusion of the kidney of nonvascular origin. Description of a case and review of the literature

A review of published series about 56 cases with unilateral nonvisualization on excretory urography after external trauma have been described: the renal injury causing the nonvisualization was contusion in 8 patients, laceration in 13, rupture in 12 and renal pedicle in 19. The acquisition of the most important methods has allowed a total view as about minimal lesions (contusion, laceration), as rupture or fragmentation of the kidney and renal pedicle. We have evaluated 32 cases of renal traumatic injuries and we have studied one case with unilateral nonvisualization stressing the diagnostic, etiopathogenetic and therapeutic problems.
