The most meticulous technique is needed, the adequate amount of contrast medium should be used, compression of the ureters should be performed and under optimum conditions tomography during the nephrographic phase should be performed whenever the circumstances should require it. With only very few exceptions no significant differences between different contrast media exist. The use of medium speed high contrast x-ray films as well as the use of rare earth intensifiers screens avoid the need for extremely powerful generators that are very costly.
