Diagnostic Evaluations of Different Radiological Examinations in Renal Tuberculosis

Objective: To discuss the diagnostic evaluations of different radiological examinations in renal tuberculosis (RTB). Methods: All patients were examined by B-scan, intravenous urography (IVU) and MRU, and 10 of them were examined by CT. Results were compared with those of operation and pathology. Results: All of the 24 cases showed positive results by B-scan in which 18 cases were diagnosed renal tuberculosis (75.0%) with typical representation of some irregular liquid-hypoecho area in kidney and 6 cases were misdiagnosed hydronephrosis and renal cyst (25.0%). Ten cases were diagnosed renal tuberculosis (1.7%) by IVU with calyx dilatation and ulceration (4 cases), cervical part of superior calyx got thinner (1 case), contrast medium lake connected with inferior calyx (1 case) and stenosis of ureter (2 cases). Eighteen cases were diagnosed renal tuberculosis (75%) by MRU with calyx dilatation and derangement (14 cases), cervical part of calyx got thinner (4 case), irregular high signal in renal parenchyma (6 cases) and ureter rigor and stenosis (4 cases). Conclusion: Various manifestations of images are shown in renal tuberculosis. Correct diagnosis depends on comprehensive analysis.
