Imaging and differential diagnosis of renal tuberculosis

Objective:To explore the imaging features of renal tuberculosis,to improve the diagnosis and differential diagnosis this disease.Methods:The clinical materials and imaging findings of 33 cases.Of 21 cases with renal tuberculosis confirmed by pathologically and 12 cases proved by clinically were retrospectively study.Results:In 33 cases renal tuberculosis:12 cases performed by phleb-urography,30 cases performed by computed tomography,8 cases performed by magnetic resonance.There were some distinctive findings of renal tuberculosis.Main features of renal tuberculosis were modified in outline,have hypointense density in renal parenchyma,to destroy and stricture in renal pelvis and renal calices,focus of infection have punctiform or stippled calcification,and thickness of tubal wall,to encroach on periphery texture.Conclusion:Imaging findings have important value in making correct diagnosis and differential diagnosis of renal tuberculosis.
