目的：探讨胎儿阴茎阴囊转位的声像图特征及超声在诊断此畸形中的应用价值。方法分析10例产前超声系统检查诊断为阴茎阴囊转位胎儿的二维及三维超声声像图，并与引产后生殖器外观形态进行对比，找出胎儿阴茎阴囊转位的声像图特征及可能导致发育异常的因素。结果10例胎儿足月生产6例，家属选择引产4例。生后经小儿外科医师会诊检查均证实为阴茎阴囊转位，10例均为部分性阴茎阴囊转位，并同时合并尿道下裂，其中3例合并肛门闭锁，足月生产6例中2例合并隐睾。6例母体早孕期间行黄体酮或地屈孕酮保胎治疗。胎儿阴茎阴囊转位有典型的声像图特征：胎儿外生殖器形态失常，阴囊分离，阴茎短小并下弯，阴茎位于分离阴囊中间或下方。可通过实时超声观察胎儿喷尿尿流走向，确定尿道口的大体位置，估测尿道下裂类型。结论胎儿阴茎阴囊转位具有典型的声像图特征，产前超声对阴茎阴囊转位的诊断和鉴别诊断提供了可靠的诊断依据，该畸形与孕期应用保胎药物有一定联系。
目的：探討胎兒陰莖陰囊轉位的聲像圖特徵及超聲在診斷此畸形中的應用價值。方法分析10例產前超聲繫統檢查診斷為陰莖陰囊轉位胎兒的二維及三維超聲聲像圖，併與引產後生殖器外觀形態進行對比，找齣胎兒陰莖陰囊轉位的聲像圖特徵及可能導緻髮育異常的因素。結果10例胎兒足月生產6例，傢屬選擇引產4例。生後經小兒外科醫師會診檢查均證實為陰莖陰囊轉位，10例均為部分性陰莖陰囊轉位，併同時閤併尿道下裂，其中3例閤併肛門閉鎖，足月生產6例中2例閤併隱睪。6例母體早孕期間行黃體酮或地屈孕酮保胎治療。胎兒陰莖陰囊轉位有典型的聲像圖特徵：胎兒外生殖器形態失常，陰囊分離，陰莖短小併下彎，陰莖位于分離陰囊中間或下方。可通過實時超聲觀察胎兒噴尿尿流走嚮，確定尿道口的大體位置，估測尿道下裂類型。結論胎兒陰莖陰囊轉位具有典型的聲像圖特徵，產前超聲對陰莖陰囊轉位的診斷和鑒彆診斷提供瞭可靠的診斷依據，該畸形與孕期應用保胎藥物有一定聯繫。

Objective To observe the ultrasonic characteristics and their value of antenatal diagnosis of fetal penoscrotal transposition.Method Ultrasonograms of 10 fetuses diagnosed of penoscrotal transposi-tion with conventional and three-dimensional prenatal ultrasound were analyzed,and the characteristics were discussed.The prenatal characteristics were summarized by ultrasound and compared with those of antopsy.To analyze the ultrasonic characteristics and discuss the factors that may lead to developmental abnormalities.Results Of 10 tetuses,6cases of full-term were born,4 cases were induced labor.10 were proved to have penoscrotal transposition after physical examination,all of them were incomplete and ac-companied with hypospadias.3 were accompanied anal atresia.2 were accompanied cryptorchidism in which were born of full-term.6 matrixes once accepted tocolytic therapy with progesterone during early pregnan-cy.T he ultrasonographic features of fetal penoscrotal transposition can display abnormal anatomy of fetal genitalia,such as small penises with chordee,or penises that are localized between or below separated scrotum.Real-time ultrasound can be applied to observe the flow of fetal urination,and thus identify the probable site of urethral meatus and infer the type of hypospdias.Conclusions Fetal penoscrotal transpo-sition has some ultrasonic characteristics Therefore,prenatal ultrasound provides the reliable basis for di-agnosis and differential diagnosis of fetal penoscrotal transposition,that is,to some extent,associated with tocolytic drug use during pregnancy.
