[The intravenous urography with rapid sequence films of the early arterial phase (author's transl)].

The intravenous urography alone as a screening-test in renal and renovascular hypertension does not give the expected results. A technique is described how to improve and enlarge the sensitivity of the intravenous urography by rapid sequence films of the early arterial phase. By the opacification of the aorta and the renal arteries it is possible to detect a renovascular hypertension. Hexabrix is a well tolerated contrast medium, which because of its low osmolality is suitable for injection as a bolus.
