[Tomography in excretory urography (author's transl)].Urologe A. 1976 Nov; 15(6):282-7.U
Urographic diagnosis has been significantly improved by the routine addition of tomography. This simple, effortless and time saving technique has resulted in the salvage of urographic studies that would otherwise have been considered indeterminate. Repeated-examinations are avoided. Tomography has also demonstrated lesions where conventional urograms have been considered normal. Finally renal lesions already demonstrable by conventional urography, can be better interpreted and analyzed.
