The objective of this study was to establish ultrasonographic guidelines for the prenatal diagnosis of fetal pelvic kidneys and assess the relationship to clinical outcome. The records of all ultrasonographic diagnoses of a fetal pelvic kidney between 1 January 1991 and 31 December 1993 were reviewed. After review of the sonographic evaluation, the prenatal records were obtained, to assess demographic data as well as the obstetric course and neonatal outcome. If a fetal pelvic kidney was suspected on prenatal ultrasound examination, its precise location and size were recorded and compared with neonatal sonograms. Twenty-six cases of fetal ectopic kidney were diagnosed of which 13 were on the right side and 13 on the left (24/26 cases were diagnosed in the late second trimester). The size of the ectopic kidney did not differ from that of the normal kidney. Except for one case of hydronephrosis, there were no associated structural anomalies. All prenatal diagnoses were confirmed by postnatal sonograms and all neonates had normal renal function. Our conclusions are that prenatal sonographic detection of fetal pelvic kidney is feasible, although in most cases the diagnosis is made beyond 24 weeks' gestation. The importance of prenatal diagnosis is that the parents can be reassured that normal renal function is highly probable and that early neonatal intervention is usually unnecessary.
本研究的目的是建立胎儿盆腔肾产前诊断的超声检查指南，并评估其与临床结局的关系。回顾了1991年1月1日至1993年12月31日期间所有胎儿盆腔肾超声诊断的记录。在回顾超声评估后，获取产前记录，以评估人口统计学数据以及产科过程和新生儿结局。如果产前超声检查怀疑有胎儿盆腔肾，则记录其确切位置和大小，并与新生儿超声图像进行比较。共诊断出26例胎儿异位肾，其中13例在右侧，13例在左侧（26例中有24例在孕中期晚期诊断）。异位肾的大小与正常肾无差异。除1例肾盂积水外，无其他相关结构异常。所有产前诊断均经产后超声图像证实，所有新生儿肾功能均正常。我们的结论是，产前超声检测胎儿盆腔肾是可行的，尽管大多数情况下诊断是在妊娠24周后做出的。产前诊断的重要性在于可以让父母放心，胎儿很可能具有正常肾功能，并且通常无需早期新生儿干预。
