[Orientation of indications for renal arteriography from arterial time in intravenous urography].
Measurement of the circulation time using dycholium allows us to estimate the arrival time of the opaque medium at the renal pedicle. Xrays taken at a very early stage will show up the abdominal aorta and renal arteries. The pictures can then be greatly clarified by a subtraction technique. In this way we have a method which, with but little change in the traditional technique for intravenous pyelography, enters into the question of whether renal arteriography is justified when it is required to demonstrate only the major arterial vessels.
