Urinary tract anomalies are common. Prenatal diagnosis is important and enables either special obstetric management or termination of pregnancy and probably in the future, intrauterine intervention. Transvaginal sonography (TVS) allows visualization of the normal and anomalous fetal urinary tract at an early stage. One thousand nine hundred and forty women were examined via TVS at an early stage of pregnancy between 10 and 16 weeks from the last menstrual period (LMP) and 35 anomalies (1.8 per cent) were clearly identified: 29 cases of low urinary tract obstruction, 2 cases of multicystic dysplastic kidney, 2 cases of polycystic kidney (infantile type), 1 case of double collecting system, and 1 case of horseshoe kidney. Potter syndrome could be ruled out in three patients who had delivered fetuses suffering from this anomaly in previous pregnancies. The concise and early identification of anomalies makes TVS an important aid in the hands of the obstetrician, ultrasonographer, and neonatologist.
泌尿系统异常很常见。产前诊断很重要，它能实现特殊的产科管理或终止妊娠，而且在未来或许还能进行宫内干预。经阴道超声检查（TVS）能够在早期对正常和异常的胎儿泌尿系统进行可视化观察。1940名女性在末次月经（LMP）后10至16周的妊娠早期接受了TVS检查，共明确识别出35例异常（1.8%）：29例下尿路梗阻、2例多囊性发育不良肾、2例多囊肾（婴儿型）、1例双集合系统以及1例马蹄肾。在之前妊娠中曾分娩患有这种异常胎儿的3名患者中，可排除波特综合征。异常情况的简洁且早期识别使TVS成为产科医生、超声科医生和新生儿科医生的一项重要辅助手段。
