[Critical analysis of angiography in renal traumatology (author's transl)].

From this analysis of a series of 39 cases of trauma submitted to angiography, it can once again be said that surgical indications and tactics are essentially determined by vascular involvment. Renal arteriography is therefore alone capable of answering two primordial questions: "Must surgery be undertaken and when operating, what surgical tactics to adopt". It must be preceded by full arteriography which enables one to evaluate associated lesions (spleen 15%), at the same time as it orientates selective arteriography. The I.V.P. is a correct means of approach but is only significant in 60% of cases. Abstention from radiological investigation as a primary requisite is unpardonable and can leave irreversible sequels. (10% of cases).
