摘要
目的探讨不同孕周胎儿肾盂宽度的正常参考范围及胎儿肾盂积水的诊断标准。方法选取来我院做产前超声检查的中、晚期妊娠胎儿共5988个肾脏作为研究对象,观察并记录肾盂宽度,经统计学处理制定胎儿不同孕周肾盂宽度的正常参考范围。结果胎儿不同孕周肾盂宽度均呈正偏态分布。其正常参考范围为:16～19周,≤0.23cm;20～23周,≤0.46cm;24～27周,≤0.74cm;28～31周,≤0.94cm;32～35周,≤1.08cm;36～39周,≤1.18cm;≥40周,≤1.20cm。结论胎儿不同孕周肾盂宽度有一定的正常范围可参考,大于正常参考范围可诊断为肾积水。胎儿轻至中度肾积水多数是一个可恢复性的过程。
Objective To investigate the normal value of the renal pelvic diameter （RPD） in fetuses with various gestational weeks and the diagnostic criteria of fetal hydronephrosis were assessed. Methods The RPD of 5988 kidneys in our hospital was observed and examined by ultrasound. The statistical management constituted the normal value of the RPD in various gestational weeks. Results The RPD of fetuses in various gestational weeks was positive skewness. The normal values of the RPD in various gestational weeks were 16-19 weeks, ≤0.23cm;20-23 weeks, ≤0.46 cm;24-27 weeks, ≤0.74 cm;28-31 weeks, ≤0.94 cm;32-35 weeks, ≤1.08 cm;36 - 39 weeks, ≤1.18 cm; ≥40 weeks, ≤1.20 cm, respectively. Conclusions The RPD of fetuses in various gestational weeks has normal value. The hydronephrosis could be diagnosed in case the RPD of fetuses is higher than the normal value. The mild and moderate hydrone-phrosis of fetuses is a restorable process.
