The aim of this study was to evaluate the value of neonatal renal ultrasonography in the diagnosis of urinary tract malformation pathologies in newborns from pregnancies complicated by late oligohydramnios.
During the period January 1994-October 1997, 119 newborns from pregnancies complicated by oligohydramnios occurring in the third trimester of pregnancy underwent ultrasonography of the urinary tract at our Centre. All newborns had previously undergone prenatal ultrasonography.
Ultrasonography revealed calicopyelic dilatation < 10 mm in 7 newborns (5.8%), 5 of whom had already been reported at the prenatal ultrasonography. One new-born (0.8%) also showed the presence of an ectopic kidney that had not been diagnosed at the prenatal scan. By the next follow-up all the calico-pyelic dilatations had become normal.
Neonatal ultrasonography did not show any alterations to the urinary tract that might be responsible for the reduction of amniotic liquid. We therefore feel that is useful to perform neonatal ultrasonography in those situations in which the onset of oligohydramnios occurred in the second trimester of pregnancy and in cases in which no scan was performed during the prenatal period.
本研究旨在评估新生儿肾脏超声检查对妊娠合并晚期羊水过少的新生儿尿路畸形病变的诊断价值。
1994年1月至1997年10月期间，我院对119例妊娠晚期出现羊水过少的新生儿进行了尿路超声检查。所有新生儿此前均已接受产前超声检查。
超声检查发现7例新生儿（5.8%）肾盂肾盏扩张<10mm，其中5例在产前超声检查中已有报告。1例新生儿（0.8%）还显示存在异位肾，产前扫描未诊断出。到下一次随访时，所有肾盂肾盏扩张均已恢复正常。
新生儿超声检查未显示任何可能导致羊水减少的尿路改变。因此，我们认为在妊娠中期出现羊水过少以及产前未进行超声检查的情况下，进行新生儿超声检查是有用的。
