目的

利用三维超声容积自动测量(VOCAL)技术检测胎儿膀胱的发育,建立不同孕周胎儿膀胱的最大和最小容积正常参考值范围,并对其与孕周的关系作出评价。

方法

选取2014年4至11月中国医科大学附属盛京医院超声科进行产前超声检查的孕16~38周孕妇,每个孕周筛选出15例,共计345例孕妇。对筛选出的健康胎儿应用经腹三维超声VOCAL技术获得胎儿最大、最小膀胱容积,采用线性相关分析评估孕周与胎儿最大膀胱容积、最小膀胱容积的相关性。

结果

三维超声VOCAL技术测得345例孕妇16~38各孕周胎儿最大膀胱容积、最小膀胱容积的均值、标准差及95%可信区间,并绘制出胎儿最大膀胱容积、最小膀胱容积与孕周关系的散点图。正常胎儿最大、最小膀胱容积与孕周呈正相关(R2max=0.99、R2min=0.98,P值均<0.01)。

结论

三维超声VOCAL技术可测量胎儿膀胱容积,其随孕周的增加而增大。

Objective

To evaluate the development of fetuses bladder by ultrasound virtual organ computer-aided analysis (VOCAL) technique, and establish the maximum and minimum bladder volume reference ranges of normal fetuses to conclude the relationship between the volume and gestational age.

Methods

From April, 2014 to November, a total of 345 normal fetuses at the 16-38th gestational week (15 normal fetuses at each gestational week) underwent examinination in Shengjing Hospital of China Medical University and were selected. Maximum and minimum bladder volumes of fetuses were measured and the relationship between bladder volume and gestational age were analyzed.

Results

The maximum and minimum bladder volume were obtained in 345 fetuses at the 16-38th gestational week, including average value, standard deviation and 95% confidence intervals. The maximum and minimum bladder volume of normal fetuses were curvilinearly associated with gestational age (R2max=0.99, R2min=0.98, all P<0.01).

Conclusion

Three dimensional ultrasound VOCAL technique can measure the bladder volume which is increasing with the gestational age.
