【摘要】：目的探讨胎儿尿道下裂的产前超声特征,并比较其正确诊断率。资料与方法回顾性分析28例超声疑似或出生后证实为尿道下裂畸形胎儿的资料,分析其产前超声特征及漏误诊情况,比较不同超声特征对尿道下裂的正确诊断率。结果28例胎儿,出生或引产后尸检证实尿道下裂21例(其中2例超声漏诊),非尿道下裂但超声误诊7例,其中二维超声正确诊断率67.9%(19/28),三维超声联合二维超声正确诊断率92.9%(13/14);不同超声征象诊断胎儿尿道下裂准确率:喷尿异常100.0%(6/6)、尿道显示异常92.9%(13/14)、"郁金香征"88.2%(15/17)、单纯阴茎末端形态异常83.3%(5/6)、阴囊分离和(或)阴茎阴囊转位25.0%(1/4)、单纯阴茎短小33.3%(1/3)。结论胎儿喷尿异常、尿道显示异常、"郁金香征"、阴茎末端形态异常等超声特征对胎儿尿道下裂的产前诊断有重要价值;三维超声比二维超声形象直观,并提供更多细节信息;综合分析所有超声特征有助于产前正确诊断。
[Abstract]:Objective to investigate the prenatal ultrasonographic features of fetal hypospadias and to compare the correct diagnostic rate of hypospadias. Materials and methods 28 cases of hypospadias confirmed by ultrasonography or postnatal hypospadias were analyzed retrospectively. The antepartum ultrasonographic features and misdiagnosis of hypospadias were analyzed and the correct diagnostic rates of hypospadias were compared. Results Twenty-one cases of hypospadias were confirmed by autopsy after birth or induced labor in 28 fetuses. Among them, 2 cases were missed by ultrasound, 7 cases were misdiagnosed by ultrasound without hypospadias. The correct diagnosis rate of two dimensional ultrasound was 67.9%, the correct diagnosis rate of three-dimensional ultrasound combined with two-dimensional ultrasound was 92.9 / 14; the accuracy of different ultrasound signs in diagnosing hypospadias of fetus was 100.00.010 / 6%; the urethral abnormality was 92.9% 13 / 14%; the tulip sign 88.21515 / 17; and the simple end of penis shape. The abnormal state was 83.3%, the scrotum separation and / or penis scrotum transposition 25.0 / 4, and the simple penis short 33.33.3 / 1 / 3. Conclusion Ultrasonic features such as abnormal ejection, abnormal urethral display, tulip sign and abnormal morphology at the end of penis have important value in prenatal diagnosis of fetal hypospadias, 3D ultrasound is more intuitive than two-dimensional ultrasound, and more detailed information is provided. Comprehensive analysis of all ultrasonic features is helpful to correct prenatal diagnosis.
