摘要
目的:应用超声检查,研究胎儿不同时期肾积水的变化、转归及肾积水胎儿出生后的生存状况。方法:从中期妊娠孕妇中筛选肾积水肾脏251只,以横切面前后径(APD)为标准,按肾脏集合系分离的分离前后径测值分成Ⅲ级;胎儿时期分3个阶段随访,出生后分4个阶段随访,最长随访时间为3年,观察不同时期肾积水的变化、转归及肾积水胎儿出生后的生存状况。结果:孕24周前胎儿生理性积水男性高于女性,77%在孕周晚期或出生后3个月内消失,病理性肾积水发生率为0.21%,男女无差别;30只病理性肾积水肾脏,9例患儿出生后3月手术治疗,诊断多为输尿管狭窄,患儿术后8只残留肾脏肾功能良好;未手术的21只肾脏积水,观察期内肾积水无增加,肾功能检查正常,积水肾脏也多为输尿管狭窄引起。结论:胎儿肾脏积水大多数为生理性的,出生后大部分在一年之内恢复正常,病理性肾积水胎儿出生后早期手术治疗可保持正常肾功能。
Objective： To study the changes of fetal hydronephrosis at different periods and the outcome,and to investigate their living conditions. Methods： A total of 251 hydronephrotic kidneys of fetuses of mid pregnant women were chosen and divided into 3 levels according to anteroposterior diameter（ APD） of the cross section of set system. Fetal period was divided into 3 stages for follow-up,and the period after the birth was divided into 4 stages. The changes of fetal hydronephrosis at different periods,the outcome,and their living conditions were observed. Results： Before 24 weeks of pregnancy,the incidence of fetal physiological hydronephrosis in male was higher than that in female,and77% of that disappeared at late pregnancy or during 3 months after birth. The incidence of pathological hydronephrosis was 0. 21%,and the difference between male and female was not significant. 9 cases in 30 pathological hydronephrotic kidneys accepted operation and diagnosed as ureteral stenosis,after operation,residual renal function of 8 cases was good. The other 21 cases with pathological hydronephrosis didn＇t accept operation,hydronephrosis was not increased during observation period,and they were almost caused by ureteral stenosis. Conclusions： Most fetal hydronephrosis are physiological and can recover within a year after birth.
