【摘要】 目的:了解围产期胎儿肾积水的转归。方法:对32～39周胎儿进行超声检查,诊断肾积水39例。生后继续用超声观察,随访1个月～7年。结果:10/39例小儿生后发病,余恢复正常。手术证实肾积水原因有肾盂输尿管连接处狭窄、后尿道瓣膜、输尿管囊肿、巨输尿管等。结论:胎儿期肾积水者若仅为肾盂扩张(1.0～1.5cm),生后积水可消失;若同时有肾实质扩大,生后部分患儿发生肾积水;若肾盂扩张大于1.5cm,且肾实质变薄,生后均有肾积水。更多还原

【Abstract】 Objective:To study the changes and prognosis of fetus with hydronephrosis in perinatal period.Methods:Ultrasonography was used to examine the fetus from 32 to 39 weeks of pregnancy.Thirty-nine fetuses were diagnosed as hydronephrosis and followed-up from 1 month to 7 years after brith.Results:Of them,10 neonates were diagnosed as hydronephrosis after birth and confirmed by operation.Hydronephrosis might not be found after birth when fetal pyelectasis was about 1.0 to 1.5 cm in diameter.Hydronephrosis occurred in some neonates with simutaneous cortical dilatation.And in all neonates when fetal pyelectasis was bigger than 1.5 cm and renal cortex became thinning.The causes of hydronephrosis confirmed by operation were pyeloureter junction stenosis,post urethral valve,ureterocele,megalo-ureter and etc.Conclusions:Most of fetus with mild pyelectasis may recover.But fetus with hydronephrosis and thinning renal cortex after birth should be observed closely and treated in time.更多还原
