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。
Purpose To investigate the prenatal ultrasonic features of fetal hypospadias and to compare the diagnostic accuracy. Materials and Methods The clinical data of 28 patients with suspected or confirmed hypospadias were retrospectively analyzed. The prenatal ultrasonic features, missed diagnosis and misdiagnosis of the patients were analyzed, and the diagnostic accuracy of different ultrasonic features for hypospadias was compared. Results In 28 cases, 21 cases of hypospadias were confirmed by examination after birth or induced abortion with 2 cases of missed diagnosis by ultrasound, and 7 cases of non hypospadias were misdiagnosed by prenatal ultrasound. The diagnostic accuracy rate of 2D ultrasound was 67.9%（19/28）, and that of 3D ultrasound combined with 2D ultrasound was 92.9%（13/14）. The diagnostic accuracy rates of ultrasonic features such as abnormal urinary jet, abnormal urethra, ＂tulip sign＂, abnormal penis tip, scrotum separation with or without penoscrotal transposition and short penis were 100.0%（6/6）, 92.9%（13/14）, 88.2%（15/17）, 83.3%（5/6）, 25.0%（1/4） and 33.3%（1/3）, respectively. Conclusion The ultrasonic features including abnormal urinary jet, abnormal urethra, ＂tulip sign＂ and abnormal penis tip have great value for prenatal diagnosis of fetal hypospadias. 3D ultrasound is more intuitive than 2D ultrasound and provides more details. Comprehensive analysis of all ultrasonic features is helpful for prenatal diagnosis.
