To compare vaginal axis and posterior cul-de-sac measurements in women who have undergone hysterectomy and women with an intact uterus.
This was a retrospective cohort study comparing magnetic resonance imaging findings in women who had undergone hysterectomy with women with an intact uterus. The primary outcome was change in the upper, middle, and lower vaginal axes relative to the pelvic inclination correction system line. Secondary outcomes included angles between the upper-middle and middle-lower vagina, depth of the posterior cul-de-sac, and total vaginal length.
In the hysterectomy group, the middle vaginal axis was significantly more anterior as compared with the intact uterus group (61.3 degrees ± 12.7 vs 49.4 degrees ± 23.6, P = 0.01). The upper-middle and the middle-lower vaginal angles were significantly more obtuse in the hysterectomy group than the intact uterus group (112.3 degrees ± 28.7 vs 69.3 degrees ± 56.6, P = 0.01 and 145.4 degrees ± 13.2 vs 130.9 degrees ± 29.7, P = 0.02, respectively). The mean depth of the posterior cul-de-sac and the total vaginal length were significantly shorter in the hysterectomy group than the intact uterus group (5.5 mm ± 7.6 vs 21.8 mm ± 11.9, P < 0.0001 and 78.7 mm ± 3.9 vs 100 mm ± 15.9, P < 0.001, respectively).
The vaginal anatomy of women who have undergone hysterectomy differs significantly from that of women with an intact uterus.
比较接受子宫切除术后的女性与子宫完整的女性的阴道轴和后穹窿测量值。
这是一项回顾性队列研究，比较接受子宫切除术后的女性与子宫完整的女性的磁共振成像结果。主要结局是相对于骨盆倾斜校正系统线，上、中、下阴道轴的变化。次要结局包括上中段和中下段阴道之间的角度、后穹窿深度和阴道总长度。
子宫切除组中，与子宫完整组相比，中段阴道轴明显更靠前（61.3度±12.7 vs 49.4度±23.6，P = 0.01）。子宫切除组的上中段和中下段阴道角度比子宫完整组明显更钝（分别为112.3度±28.7 vs 69.3度±56.6，P = 0.01；145.4度±13.2 vs 130.9度±29.
