On the basis of a series of fifty-one blunt renal injuries and a revie
w of literature, the characteristics of this affection are reviewed. T
his trauma typically occurs in young adults. Minor injuries are the mo
st frequent (75,5 percent) and associated lesions are not rare. Comput
ed tomography is the imaging technique of choice for renal trauma asse
ssment. It can, sometimes, be replaced by urography-ultrasonography co
uple. Indications of these imaging modalities are reviewed. A classifi
cation in four types, adapted to new imaging methods, is proposed to h
armonize or to compare therapeutic indications. The different therapeu
tic methods, their indications and their particularities are studied a
nd a simple decisional strategy is proposed.
