[Current radiation diagnosis of pyelonephritis]

The paper deals with the current diagnosis of nonspecific and specific (tuberculosis) acute and chronic pyelonephritis. Having rather ample materials (308 patients with different forms of acute and chronic pyelonephritis), the authors compared different introscopic techniques (plain X-ray study, excretory urography, retrograde pyelography, ultrasonography, computed tomography and angiography) used in the diagnosis and monitoring of patients with pyelonephritis. Based on their own findings and on the data available in the literature, the authors described the symptomatology of pyelonephritis in detail by using a great variety of diagnostic techniques. The paper shows the place and potentialities of conventional X-ray in a variety of current diagnostic studies and the potentialities of imaging techniques in recognizing pyelonephritis, assessing their extent and the reserve potentialities of the diseased kidney. The authors show that the rational use of routine and current radiographic techniques is of great diagnostic and prognostic value, enhances the efficiency of therapy for pyelonephritis, shortens treatment periods, reduces the number of radical nephrectomies by using organ-sparing operations more widely, and decreases mortality rates.
