产前超声测量胎儿肾腹横截面积比值的意义

Value of Prenatal Ultrasonography in Measuring the Area Ratio of Fetal Renal Abdominal Transverse Section

目的探讨产前超声测量胎儿肾腹横截面积比值的意义。方法将接受常规产前超声检查的150名18~40周孕妇,按孕龄分为18~25周组,26~32周组,33~40周组,各50名。对其进行肾脏长径、横截面积及胎儿肾腹横截面积的测量,进行相关统计学处理。结果在整个18周后妊娠期中,胎儿肾脏长径、横截面积随孕龄呈线性增长,差异无统计学意义(P>0.05);胎儿肾腹横截面积比值变化差异有统计学意义(P<0.05)。结论根据胎儿肾腹横截面积比值变化,产前超声测量方法可在临床评估胎儿肾脏发育方面发挥重要作用。

Objective To study the value of prenatal ultrasound in measuring the area ratio of fetal kidney. Methods 150 cases of 18—40 weeks pregnant in my hospital for routine prenatal ultrasound examination were chosen and according to gestational age grouping were divided into three groups,18—25weeks group（ 50 cases）,26—32 weeks group（ 50 cases）,33—40 weeks group（ 50 cases）,on three groups of pregnant women and fetus were kidney length diameter,cross- sectional area and fetal renal abdominal cross- sectional area measurements and related statistical processing. Results In 18 weeks after the pregnancy,the fetal kidney length and cross- sectional area increased linearly with the gestational age,and there was no significant difference（ P〈0. 05）; using single factor analysis of variance and fetal renal abdominal cross- sectional area ratio variation differences,was statistically significant（ P〈0. 05）. Conclusion Clinical application prenatal ultrasonic measurement method,according to the fetal renal abdominal cross- sectional area ratio variation,in the clinical assessment of fetal kidney development play an important role.
