[Improvement of excretory urography with the routine use of tomography (author's transl)].

The additional use of routine tomography during excretory urography in our experience has led to a significant improvement in urographic diagnosis. Tomography has provided more diagnostic studies, it also has demonstrated tumors which would have remained undetected with the use of conventional urography alone. This applies particularly to small hypernephromas of stage A, which should be considered as curable.
