彩色多普勒超声对于儿童先天性巨输尿管症的诊断价值

目的 探讨彩色多普勒超声对于儿童先天性巨输尿管症的诊断价值.方法 对2005年1月至2010年10月间经我院手术证实的80例先天性巨输尿管症患儿的超声影像结果进行统计学分析.所有患儿在术前均行彩色多普勒超声检查.结果 经手术证实80例患儿101侧输尿管被确诊为巨输尿管（其中21例患儿为双侧巨输尿管）,左侧43例;右侧16例;双侧为21例,有巨输尿管的同侧肾脏多伴有不同程度积水.101侧巨输尿管中95侧由超声首先确诊;80例患儿术前同时行超声及IVP的患者为45例,共有54侧巨输尿管（其中9例为双侧巨输尿管）,超声检出率93.6%（50例/54侧）,IVP检出率81.5%（44例/54侧）,两者对于巨输尿管的检出率差异有统计学意义（P〈0.05）.结论 对于儿童先天性巨输尿管症的诊断,超声检出率更高,便捷无创,有很高的诊断价值.

Color Doppler ultrasound in diagnosis of children with congenital megaureter

Objetive To explore the diagnostic value of color doppler ultrasound for congenital megau- reter in children. Methods Analyzed the findings of ultrasonic image in 80 patients with congenital megau- reter from January 2005 to October 2010. All cases involved were confirmed by operations in our hospital. All patients were examined via ultrasound before their respective operations. Results Our hospital operations found that 80 patients （ 101 sides） were diagnosed as megaurete. The anomaly was on the left side in 43 cases, on the right side in 16 cases and bilateral in 2l cases. The congenital megaureter ipsilateral kidney combined varying degrees of hydronephrosis. Of the 101 cases with megaureter, 95 were diagnosed first via ultrasound; 45 patients （54 lateral megaureters） were examined via ultrasound and intravenous urography （IVP） examination. The detection rate of ultrasound diagnosis was 93.6% （50/54 sides） and the detection rate of IVP was 81.5% （44/54 side）, implying statistical difference between them （P 〈 0. 05）. Conclusions Color Doppler ultra- sound is a very important method in the diagnosis of congenital megaureter because it has many merits, inclu- ding high detection rate, convenience, and non-invasiveness, etc.
