| 探讨小肾癌及尿路上皮癌超声检查漏误诊原因。方法 回顾性分析11例小肾癌及7例尿路上皮癌的声像图特征。结果 11例小肾癌2例误诊为错构瘤，病灶均为高回声，1例内部及周围见血流信号；4例误诊为囊肿，3例病灶为囊性，1例回声较低；漏诊5例。7例尿路上皮癌误诊为血凝块1例，肾盂旁囊肿1例，漏诊5例。结论 超声对小肾癌具有较高的诊断价值，但存在局限性，且超声医生对尿路上皮癌认识不够，应结合多种影像学检查，减少漏误诊率。 |

| Abstract: |
| To explore missed diagnosis and misdiagnosis of small renal carcinoma and urothelial carcinoma. Methods The sonography features of 11 cases of small renal carcinoma and 7 cases of urothelial carcinoma were analyzed retrospectively.Results the type of misdiagnosis cases were as follow: there were 2 cases of angiomyolipoma of kidney which were hyper-echoic and 1 case showed internal and peripheral blood signal; 4 cases of renal cyst which were cystic of 3 cases; 5cases missed diagnosis in 11 cases of small renal carcinoma. There were 1 case of blood clot, 1case of parapelvic cyst, 5 cases missed diagnosis in 7cases of urothelial carcinoma. Conclusions Ultrasonography has high diagnostic value in small renal carcinoma, but still has some limitations, and sonographers lack awareness of urothelial carcinoma. we should combine with various imaging technique, to reduce rate of missed diagnosis and misdiagnosis. |
