产前超声对46例孕妇的胎儿肾盂扩张诊断及预后评估

Prenatal diagnosis and prognosis of 46 fetal pyelectasis by ultrasound

目的探讨产前超声对胎儿不同程度肾盂扩张的诊断及预后评估价值。方法对2007年3月～2008年7月门诊定期产前检查孕妇进行胎儿产前超声筛查的46例肾盂扩张的病例进行随访观察。结果46例中除2例失访,1例引产外,43例在孕期发现肾盂扩张并进行出生后的随访,发现APD<15mm能在出生后1年内缓解消失,胎儿期肾盂扩张≥15mm4例均未见缓解。结论胎儿期肾盂扩张<15mm者大多数转归良好。胎儿期肾盂扩张≥15mm,伴泌尿生殖道或其他系统异常者预后较差。

Objective To investigate the evaluation of prenatal diagnosis and prognosis of fetal pyelectasis at different levels. Methods 46 pregnant women who were prenatally diagnosed with fetal pyelectasis by ultrasound were observed from March 2007 to July 2008. Results 43 cases were followed up in different gestational ages and postnatal periods except 2 cases missed and 1 case of induced abortion. Pyelectasis of anteroposterior diameter （APD） was found （ 15 mm relieved or disappearing within 1 year, while none of the cases disappeared in pyelectasis of APD ≥15 mm. Conclusions Most fetal pyelectasis of APD （ 15 mm recovers well, and fetal pyelectasis of APD ≥15 mm with genitourinary anomalies has poor prognosis.
