[Sequential angio-urography (SAU) with photographic image subtraction].
Urography was performed in 250 patients: the technique of bolus injection of a large quantity of contrast medium was used in every case. By means of rapid seriography the early vascular phase was shown and reproduced, when necessary, with image subtraction. The abdominal aorta and the renal arteries were demonstrated in 97.6% of cases. Altogether, in 34.4% of cases the existence of pathological conditions non demonstrable by conventional urography was ascertained; in 12.4% of cases extrarenal pathology was diagnosed. This technique is suggested to be used sistematically, as an alternative to DSA, where digital equipments are not available.
