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。
Objective: To understand the outcome of perinatal fetal hydronephrosis. Methods: Fetal ultrasound was performed in 32-39 weeks and 39 cases of hydronephrosis were diagnosed. After birth, continue to use ultrasound, followed up for 1 month to 7 years. Results: The incidence of 10/39 infants after birth, I returned to normal. Surgery confirmed hydronephrosis with ureteropelvic junction stenosis, posterior urethral valve, ureterocele, giant ureter and so on. Conclusions: If only hydronephrosis (1.0 ~ 1.5cm), fetal hydronephrosis can disappear after birth; if at the same time with enlarged renal parenchyma, neonatal hydronephrosis occurred in some children; if the renal pelvis expansion greater than 1.5cm , And thinning of the renal parenchyma, have hydronephrosis after birth.
