摘　　要：本文报道了1例产前诊断的胎儿脐尿管未闭并尿囊囊肿破裂致膀胱脱垂的病例。孕妇于2023年8月8日(孕12周+5)在长治医学院附属和平医院产前常规超声检查时发现双胎之一胎脐孔处向外可见一无回声区(22.0 mm×17.0 mm)凸入脐带内,通过未闭合的脐尿管与膀胱呈亚铃状相通。定期复查超声,囊肿随孕周增大,最大时38.3 mm×30.2 mm(孕23周+5)。孕33周+5复查超声显示囊肿消失,脐孔处可见一高回声团(21.3 mm×15.2 mm),膀胱反复扫查不显示,诊断为脐尿管未闭并尿囊囊肿破裂致膀胱脱垂。生后转外院诊断为膀胱脱垂并行膀胱脱垂修补术及脐整形术。术后病理证实膨出物为膀胱组织。生后2月龄随访,未见明显并发症。This article reported a prenatal diagnosis of fetal bladder prolapse caused by patent urachus and ruptured urachal cyst.On August 8,2023(12 weeks and 5 days of gestation),a routine prenatal ultrasound examination in Heping Hospital Affiliated to Changzhi Medical College revealed that one of the twins had an anechoic area(22.0 mm×17.0 mm)protruding into the umbilical cord at the umbilical opening,which was connected to the bladder in a bell-shaped manner through an unclosed urachus.Regular follow-up ultrasounds indicated that the cyst increased in size as the pregnancy progressed,the biggest was 38.3 mm×30.2 mm(23+5 gestational weeks).At 33 weeks and 5 days of gestation,ultrasound showed that the cyst had disappeared,and a high-echo mass(21.3 mm×15.2 mm)was visible at the umbilical opening,while the bladder was not visible even upon repeated scans.These observations led to the diagnosis of bladder prolapse due to patent urachus and ruptured urachal cyst.Postnatally,the infant was transferred to an external hospital for surgical treatment,where the diagnosis of bladder prolapse was further confirmed and prolapse repair and umbilicoplasty were done.Postoperative pathology verified that the protruding high-echo mass was bladder tissue.Follow-up examinations at 2 months of age showed no significant complications.
