目的:探讨肾结核的临床特点,提高对不典型肾结核的早期诊断。方法:回顾分析1981￣2001年间收治的326例患者的临床资料。结果:尿抗酸杆菌,聚合酶连反应结核菌检查阳性率分别为28.9%和42.3%。静脉尿路造影(IVU)、B超、CT、逆行造影诊断阳性率分别为85.9%。65.3%、81.5%、73.8%。结论:临床不典型肾结核病例增多。IVU仍然是肾结核诊断的首选影像学检查,CT对可疑病例有一定辅助诊断价值。IVU、CT联合实验室检查可提高不典型肾结核的诊断阳性率。
Objective: To investigate the clinical features of renal tuberculosis and improve the early diagnosis of atypical renal tuberculosis. Methods: The clinical data of 326 patients admitted between 1981 and 2001 were retrospectively analyzed. Results: The positive rates of acid-fast bacilli and polymerase chain reaction were 28.9% and 42.3% respectively. The positive rates of IVU, B-ultrasound, CT and retrograde angiography were 85.9%. 65.3%, 81.5%, 73.8%. Conclusion: There are more cases of clinical atypical renal tuberculosis. IVU diagnosis of renal tuberculosis is still the first choice of imaging, CT suspected cases have some auxiliary diagnostic value. IVU, CT combined laboratory tests can increase the diagnostic positive rate of atypical renal tuberculosis.
