目的探讨子宫倾斜角与B超测量的胎轴倾斜角的关系。方法采用子宫倾斜角测量仪和妇科B超对51例孕妇子宫倾斜角和胎轴倾斜角进行测量,分析配对资料子宫倾斜角与胎轴倾斜角的相关程度。结果在51例孕妇中,23例胎轴倾斜角向左倾斜,大小为(8.8±7.0)度;25例向右倾斜,大小为(9.6±8.2)度。子宫倾斜角与胎轴倾斜角差异无统计学意义(P=0.767 8)。子宫倾斜角与胎轴倾斜角呈线性相关(r=0.903 9,P<0.01)。结论子宫倾斜角与胎轴倾斜角有明显相关性,可以用子宫倾斜角间接反映胎轴倾斜角。
Objective To investigate the relationship between uterine inclination angle and B-axis inclination measurement. Methods Uterine tilt angle meter and gynecological B-ultrasound were used to measure the uterine inclination angle and the axis inclination angle of 51 pregnant women. The correlation between the inclination angle of the uterus and the inclination angle was analyzed. Results Twenty-one of 51 pregnant women were inclined to the left with a skew angle of (8.8 ± 7.0) degrees and 25 to the right with a size of (9.6 ± 8.2) degrees. There was no significant difference in the angle of inclination between the uterus and the axis (P = 0.767 8). Uterine lean angle was linearly correlated with lean angle (r = 0.903 9, P <0.01). Conclusion There is a significant correlation between uterine inclination angle and the inclination angle of the fetal axis. The inclination angle of the fetal axis can be indirectly reflected by the uterine inclination angle.
