胎儿肾积水的超声诊断及临床分析

Ultrasonic diagnosis of fetalhydronephrosis and its clinical analysis

目的分析胎儿肾积水的声像图特点,区分生理性肾积水和病理性肾积水,为临床进一步治疗提供依据。方法对100例胎儿怀疑肾积水的病例进行定期超声随访,追踪观察至胎儿出生一年。对正常组和肾积水组计算例数、所占百分比、APD(肾盂前后径)平均值、肾实质厚度平均值进行统计学比较。结果两组计算例数、所占百分比、APD平均值、肾实质厚度平均值均有显著性差异(P<0.05)。结论超声检查妊娠期胎儿怀疑肾积水的病例大多数为正常或是生理性的,只有少数肾积水为病理性的肾积水,正常或生理性的肾积水肾积水宽度APD<1.63 cm或肾实质厚度>0.58 cm,不需要进一步干预;病理性肾积水宽度APD>2.15 cm或肾实质厚度<0.2 cm,可视情况终止妊娠。

Objective To analyze thesonographic features of fetal hydronephrosis and its clinical significance, to consider the termination of pregnancy and provide the basis for further treatment. Methods Regular ultrasound follow- up of 100 cases of fetal hydronephrosis tracking observation of doubt, to fetal birth year. In normal group and hydronephrosis group calculation cases, percentage, APD （anteroposterior diameter）, average thickness of renal parenchyma average values were statistically compared. Results The two groups of calculation example number, percentage, average APD value, average value of renal parenchyma thickness were significantly different （ P 〈 0. 05 ） . Conclusions Ultrasound examination of fetal hydronephrosis during pregnancy that most cases as normal or is physiology sex, only a handful of hydronephrosis pathological hydronephrosis, kidney seeperhydronephrosis width APD 〈 normal or physiological 1. 63 cm or renal parenchymal thickness more than 0.58 cm; kidney seeper rational disease APD 〉 2.15 cm width or thickness of renal parenchyma 〈 0.2 cm, depending on the circumstances for termination of pregnancy.
