慢性肾炎误诊为肾结核一例患者男，２９岁，主因间断肉眼血尿二年入院。查体：尿白细胞（＋＋），红细胞（＋＋）；Ｂ超示右肾炎性改变，轻度肾盂积水；肾造影诊为右肾结核；同位素检查四次不能排除肾结核；膀胱镜未见异常；入院后两次检查到尿结核菌。但经抗结核治疗近三个月无效，转外科治疗。术中见右肾正常，沿肾上极外侧纵行切开２．５ｃｍ，肾盏亦未见结核灶，摘取肾皮质一块送病检，结果为部分肾曲管上皮细胞浊肿变性。从本例检查结果来看，造影、同位素均支持肾结核诊断。并尿结核菌阳性，唯有Ｂ超提示为炎症。说明Ｂ超对肾炎有一定诊断价值。亦说明查到尿结核菌不一定就是肾结核。（太原市中心医院吴志霞）慢性肾炎误诊为肾结核一例@吴志霞$太原市中心医院 Chronic nephritis misdiagnosed as a case of renal tuberculosis male, 29 years old, mainly due to intermittent gross hematuria hospitalized for two years.
