Prenatal ultrasonographic features of patent urachus consist in anechoic proximal cord cyst communicating with the bladder associated with large umbilicus. Distinction should be made with omphalocele and bladder extrophy. Spontaneous evolution leads to rupture during mid-trimester and bladder protrusion. Karyotyping is not mandatory in isolated typical cases. Early postnatal surgery is usually required.
脐尿管未闭的产前超声特征表现为近端脐带囊肿呈无回声，与膀胱相通，并伴有脐部增大。应与脐膨出和膀胱外翻相鉴别。自然演变会导致在孕中期破裂及膀胱突出。对于孤立的典型病例，不强制进行染色体核型分析。通常需要在出生后早期进行手术。
