46例胎儿肾积水超声诊断及预后分析

目的利用超声技术评价胎儿肾积水的预后,指导临床适时进行干预措施的实施。方法利用超声对46例61只肾积水进行随访观察,最长至出生后一年。结果肾积水程度≤15mm的34只肾中,在出生后12个月内积水程度消失。肾积水程度>15mm且≤20mm的7只肾中2只程度减轻,2只经手术解除梗阻。肾积水程度>20mm的2只肾积水孕期终止妊娠,一只经手术解除梗阻。结论胎儿肾积水出生后的转归与肾积水程度有关,彩色多普勒超声可较好地评价胎儿预后。

Objective To estimate the ptognosis of fetal hydronphrosis by ultrasound technique,and help clinician put intervention measure in practive at appropriate.Methods 46cases 61 individuals hydronephrosis whose collecting sustem are separating were observed and studied.The longest followed-up was for one year.Results Pelvic diameter15mm,enter of hydronephrosis of 34 kidneys disappears spontaneously.Pelvic diameter15mm and 20mm,extent of hydronephrosis of 2 kidneys decreases spontaneously,2 kidneys were operated.Pelvic diameter20mm,one case（two kidneys）with fetal hydronephrosis were aborted.one kidney was operated.Conclusion Prognosis of hydronephrosis ofter birth related to the extent of hydronephrosis,Color Dopple ultrasounography may provide valuable prognositic estimation for fetal hydronephrosis.
