肾结核的影像表现与鉴别诊断

目的:探讨影像学对肾结核诊断和鉴别诊断的价值。方法:33例肾结核病例中,21例经手术病理证实,12例经临床诊断。结果:33例肾结核中,12例行静脉尿路造影,30例CT检查,8例MR检查。影像学表现为肾影轮廓的改变,肾实质内低密度,肾盂肾盏破坏及狭窄,病灶内点状或斑点状钙化,输尿管的累及、周围组织的侵犯。结论:影像学对肾结核诊断及鉴别诊断有很重要的作用。

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.
