摘要
目的：通过三维超声测量胎儿肾脏体积并用这些资料来建立用二维超声测量进行估算胎儿肾脏体积的公式。方法：包括20—40孕周的单胎。用三维超声测量胎儿双侧肾脏的体积。测量胎儿肾脏的三个径线（最大前后径、横径和纵径），并计算胎儿肾脏体积的公式，计算出每侧肾脏体积与三条径线的回归曲线和系数。结果：共做了116例胎儿，建立了以下胎儿肾脏体积的公式：胎儿肾脏体积=系数（R）×最大前后径（X）×最大横径（Y）×最大纵径（Z）。在右侧和左侧肾之间，体积、三条径线和系数有所不同，但无明显差异。结论：三维超声测量胎儿肾脏体积是有用的，胎儿肾脏体积公式使二维超声测量肾脏体积更为精确。
Objective： To measure fetal renal volume by means of three - dimensional ultrasonography and to use these data to es- tablish the accurate constant and formula for fetal renal volume assessment with two - dimensional ultrasonography. Methods： Single fetuses between 20 -40 weeks＇gestation kidneys were included. The volumes of both fetal kidneys were measured with three -dimensional ultrasonog- raphy. Three fetal renal diameters （largest anteroposterior, transverse and longitudinal diameters） were measured, and the constant of the fe- tal renal volume formula was calculated. Linear regression curves were made for each kidney from the fetal renal volume, the three diameters and the constant. Results： A total of 116 fetuses were included. The following fetal volume formula was established： fetal renal volume = constant （R） × Largest anteropesterior diameter （X） × Largest transverse diameter （Y）× Largest longitudinal diameter （Z） . The volumes, the three diameters and the constants were different between the right and left kidneys but not statistically significant. Conclusion： Three- dimensional ultrasonography is useful in assessing fetal renal volume. The fetal renal volume formula makes possible accurate measurements of fetal renal volume by two - dimensional ultrasonography.
