摘　　要：目的分析胎儿脐尿管未闭合并尿囊囊肿的产前超声特点及预后,探讨产前超声诊断价值。资料与方法回顾性分析2014年10月—2021年12月无锡市妇幼保健院脐尿管未闭合并尿囊囊肿胎儿8例,总结产前超声特点,并随访其孕期及出生后情况。结果胎儿脐尿管未闭合并尿囊囊肿产前超声的特征性表现为:①脐带根部腹壁插入部位囊肿;②囊肿与胎儿膀胱相通,呈哑铃型或沙漏型,中间的通道即未闭的脐尿管;③脐动脉包绕囊肿两侧;④囊肿及未闭的脐尿管大小可随膀胱排尿状态发生改变;⑤尿囊囊肿可随孕周增加而增大,甚至破裂消失。脐尿管未闭合并尿囊囊肿可合并其他结构异常,本组中3例因合并其他结构异常引产。5例为单纯性脐尿管未闭合并尿囊囊肿:1例孕23周胎死宫内引产,3例孕晚期尿囊囊肿消失(1例囊肿消失出现脐膨出),1例尿囊囊肿持续存在且较中孕期增大;此4例胎儿足月分娩,出生后3例诊断为脐尿管瘘,1例脐尿管瘘伴脐膨出。结论胎儿脐尿管未闭合并尿囊囊肿具有特征性的产前超声表现,不伴其他异常者预后良好。Purpose To analyze the prenatal ultrasonographic features and prognosis of fetal patent urachus with allantoic cyst,and to discuss the value of prenatal diagnosis via ultrasound.Materials and Methods A total of eight cases of fetal patent urachus with allantoic cyst diagnosed by ultrasound at Wuxi Maternal and Child Health Hospital from October 2014 to December 2021 were retrospectively reviewed and summarized the prenatal ultrasonographic features with follow-up during pregnancy and after birth.Results Typical prenatal ultrasonographic features of fetal patent urachus with allantoic cyst were as follows:①a umbilical cyst closed to the fetal insertion site of the abdominal wall;②the cyst connected with the fetal bladder,dumbbell-shaped or hourglass-shaped features,and the middle channel was the patent urachus;③the umbilical artery surrounded both sides of the cyst;④the size of cyst and patent urachus changed with the size of bladder;⑤with the increased of gestational age,allantoic cyst increased or even disappeared.Patent urachus with allantoic cyst were combined with other structural abnormalities in this group,three cases were induced due to other structural abnormalities.Five cases were fetal patent urachus without allantoic cyst:one case was demised intrauterine at 23 weeks,three cases allantoic cyst were ruptured in the third trimester and omphalocele appeared in one case of them,one case allantoic cyst of third trimester was persisted and enlarged than that of the second trimester;these four cases were born at term,and three cases were diagnosed patent urechus and one case was diagnosed omphalocele with patent urachus after birth.Conclusion Fetal patent urachus with allantoic cyst has typical prenatal ultrasonographic features,the prognosis of patent urachus with allantoic cyst is better than that of without other abnormalities.
