Echography in the study of renal tuberculosis

: 34 patients suffering from renal tuberculosis of different degree were examined by ultrasound. The ultrasonographic aspects were compared with the urographic pictures. It was not possible to show by ultrasound the papillar erosions at the initial stage of the infection. In the advanced stage it was possible to evaluate the alterations of the excretory system and the parenchymal damage. The role of the method to study the tuberculous kidney, not visualized at urography, is essential. The typical aspect caused by the coarctated pelvis with dilated calyces allows nearly always to formulate a diagnosis. The achieved results make ultrasonography a very important investigation for the diagnosis and the prognosis of the renal tuberculous infection.
