超声测量孕妇肾体积预测胎儿宫内发育迟缓

用超声法对４８３例单胎妊娠的孕妇测量了肾体积，其中６８名妇的胎儿被确认为发育迟缓。晚孕期正常孕妇有ＩＵＧＲ的孕妇其平均肾体积分别增加了５７．２％和８．４％。表明新生儿出生体重和孕妇肾体积的大小有关，孕妇肾测量值的特异性９６％明显高于敏感性６５％，敏感性受到宫内发迟缓的类型和孕妇个体差异的影响。预测ＩＵＧＲ的阳性预测值为７４％。

Measurement of Renal Volume of Pregnant Women for the Predictiveness of Fetal Intrauterine Growth Retardation

The measurement of renal volume by ultrasound was carried out in 483 women with sigleton pregnancy. Sixty-eight women had infants with the intrauterine growth retardation(IUGR).The average of renal volume in normal pregnant females and females with IUGR increased 57. 2% and 8. 4% respectively during trimester. Hence, the neonatal weight outcomes were correlated with the renal volume in their mothers. The specficity of measurement was 96%, and the sensitivity was 65%.The sensitivety was influenced by type of IUGR and individual difference of renal volume. The positive predictive value was 74 %.
