[The valence of radiodiagnostic methods for retroperitoneal fibrosis (author's transl)]

The valence of radiological methods of examination for the diagnosis and observation of retroperitoneal fibrosis is presented with reference to 2 case reports and an analysis of 48 of our own patients. The i.v. urogram with breathing and profile exposures is the most important method of examination. Retrograde pyelography in the AP and lateral positions is often indispensable for preoperative diagnosis. Cavography and arteriogram are necessary to determine the extent of the vascular involvement and the extent of the fibrosis caudally.
