摘　　要：目的　探讨肾结核的CT表现及其诊断价值。方法　搜集病例 2 6例 ,对照手术病理及临床追踪 ,分析肾结核的CT表现。结果　 2 6例病例中 ,CT诊断单侧肾结核 2 2例 ,经手术病理证实 2 1例为肾结核 ,1例为假性动脉瘤 ;双侧肾结核及肾囊肿各 2例 ,经辅助检查及临床追踪均确诊为肾结核。肾结核多发空洞CT特征表现为断面上聚集成“花瓣”状多发低密度区 ,但也可有多种多样的不典型表现。单发空洞仅表现为囊状低密度影时 ,注意与肾囊肿鉴别。而早期肾结核可仅表现为肾包膜下大量积液。结论　CT扫描对肾结核诊断具有特殊价值 。Objective To evaluate the CT values in diagnosis of renal tuberculosis. Methods 26 cases were collected , the CT findings of renal tuberculosis were analysed and compared with the data of operation-pathology and clinical followed up. Results Of 26 cases, 22 cases diagnosed by CT as renal tuberculosis of one side were confirmed by operation-pathology but one (pseudaneurysm). Bilateral renal tuberculosis and renal cysts were diagnosed in 2 cases respectively by CT, while these 4 cases were confirmed as tuberculosis by other auxiliary checking methods and followed-up. The multiple tuberculoses cavities appeared as a petal-shape low-density area and other untypical signs on CT. The single cavity only showed as a low-density area should be distinguished with cystonephrosis. At early renal tuberculosis, a great quantity of effusion beneath the perinephrium was the only sign on CT.Conclusion CT scan has a special value for diagnosis renal tuberculosis. Typical renal tuberculosis can be made closely combining with the clinical information.
