Current status of excretory urography. A premature epitaph?

Although there can be no doubt that the once lofty stature of the IVU in clinical urology has been gradually eroded by many forces, the study still retains an important place in urologic diagnosis. In spite of inroads made by CT, ultra-sonography, radionuclide scans, and other modalities, there is still diagnostic information that is best supplied by the IVU. It appears safe to say that the IVU will be with us for many years to come. Indeed, it seems fair to add that the practice of urology and uroradiology would be very difficult without it.
