We report a case of persistent urogenital sinus with hydrocolpos and associated renal anomalies diagnosed prenatally at 30 weeks' gestation. The prenatal findings were confirmed on postnatal ultrasonography and genitogram with voiding urethrogram. The imaging features and a review of the literature are discussed. The possibility of hydrometrocolpos secondary to urogenital sinus should be considered on prenatal sonography in the presence of a presacral cystic mass with clear urine or turbid contents and a fluid-debris level (cervical or vaginal secretions). Because the prognosis and neonatal management of isolated hydrocolpos (which usually resolves spontaneously) differ greatly from those of hydrocolpos associated with a cloacal malformation, it is important to diagnose prenatally any associated anomalies in order to allow optimal postnatal management.
我们报告了一例产前 30 周诊断为持续性尿生殖窦伴积水性阴道和相关肾脏异常的病例。产前超声检查和生殖造影联合排尿性尿道造影均证实了这一发现。本文讨论了其影像学特征及相关文献复习。对于存在骶前囊性肿块，其内为清亮尿液或浑浊内容物，且伴有液-碎屑平面（宫颈或阴道分泌物）的胎儿，产前超声检查时应考虑尿生殖窦继发的积水性阴道的可能性。由于孤立性积水性阴道（通常可自发消退）的预后和新生儿管理与合并直肠生殖窦畸形的积水性阴道有很大差异，因此，产前诊断任何相关异常对于实现最佳的新生儿管理至关重要。
