title: [The imaging diagnosis of acute renal transplant obstruction with special reference to antegrade pyelography].
abstract: 30 patients with an acute build-up of renal transplant were examined comparatively via antegrade pyelography (AP), computed tomography (CT) and sonography (SONO). In the proof of obstructions and compressions of the ureter of renal transplant, antegrade pyelography was superior to sonography and computed tomography. Perirenal collections of fluids were recognised correctly via sonography by 73% (11/15) and computed tomography by 87% (13/15). The computer tomogram is superior in the differentiation of perirenal collection of fluids. In establishing proof of the cause of an acute build-up of renal transplant it was evident that computed tomography with a sensitivity of 64% and a specificity of 94% was slightly superior.
