超声评分法鉴别诊断胎儿肾积水的临床价值

The clinical value of ultrasound score differential diagnosis of fetal hydronephrosis

目的:研究超声评分法诊断胎儿肾积水的临床价值。方法:对肾积水胎儿进行超声检查,将横切面肾孟的最大前后径、肾实质厚度和肾盂肾盏形态分别进行超声评分并累计每个肾的总评分。根据随访结果将肾积水胎儿分为生理组和病理组,绘制超声评分法两组肾积水的操作者特征(ROC)曲线。结果:98例共108个肾积水,其中生理性79个(78.80%),病理性29个(21.20%)。对于诊断胎儿病理性肾积水,ROC曲线显示超声评分法鉴别诊断肾积水曲线下面积为96.4%,其取值6时为诊断病理性肾积水最佳截断值,灵敏性81%,特异性94%。结论:超声评分法可用于临床鉴别诊断胎儿生理性与病理性肾积水。

Objective:To research the clinical value of ultrasound score differential diagnosis of fetal hydronephrosis.Methods:Ultrasound examination of fetal hydronephrosis,the PAPD,renal parenchymal thickness and morphology of the renal pelvis were ultrasound score and cumulative total score of each kidney.According to the results of follow-up,the fetal hydronephrosis were divided into the physiological group and the pathological group group,drawing ultrasound scoring two groups hydronephrosis operator characteristic (ROC) curve.Results:98 patients with a total of 108 hydronephrosis,physiological 79 (78.80%),pathological 29 (21.20%).For the diagnosis of fetal pathological hydronephrosis,Roc curve showed that ultrasound scoring differential diagnosis of hydronephrosis under the curve area was 96.4%.The value of 6 for the diagnosis of pathological hydronephrosis was the optimal cut-off value.The sensitivity was 81% ,and the specificity was 94% .Conclusion:Ultrasound score can be used to the clinical differential diagnosis of physiological and pathological fetal hydronephrosis.
