Abstract :

Background: Tuberculosis (TB) is the most common cause of mortality and morbidity from infectious diseases. Approximately one–third of the world’s population is believed to harbor latent infection with Mycobacterium tuberculosis. Tuberculosis of the kidney results from hematogenous seeding of Mycobacterium tuberculosis in the glomerular and peritubular capillary bed from primary site of infection, usually from a pulmonary focus. This study was conducted in Department of Radiodiagnosis, Sri Sathya Sai Institute of Higher Medical Sciences, Whitefield and Department of Imaging Sciences, Sri Sathya Sai Institute of Higher Medical sciences, Prashanthigram. Results: The identification of imaging findings as renal parenchymal scarring (p< 0.01), infundibular or pelvic stenosis ( p < 0.001), thickened ureteric wall (p < 0.05) and extra urinary manifestations ( p < 0.05 ) on CT were significantly more frequent than on IVP. There was no significant difference on IVP and CT in detection of renal parenchymal mass, renal parenchyma calcification, renal parenchyma cavity, moth eaten calyx, autonephrectomy, ureteric stricture with HDUN, calcified ureteric wall and thickening of UB wall. Conclusion:CT and IVU showed a wide variety of imaging findings and all the findings, when present, were common unilaterally. Most common feature on both CT and IVU was infundibular or pelvic stenosis. CT was superior to IVU in the detection of renal parenchymal scarring, infundibular or pelvic stenosis, ureteric wall thickening and extraurinary manifestations.
