To estimate distances from the mid-urethra to the obturator foramina and to explore correlations between pelvic dimensions and body height.
This is a secondary analysis of a parent case-control study on the mechanisms of stress urinary incontinence. We measured pelvic dimensions on magnetic resonance images of women with (cases, n = 50) and without (controls, n = 50) stress urinary incontinence.
The mean distance from mid-urethra to the obturator membrane among cases is 31.8 mm (left) and 32.1 mm (right), with a range from 25.9 to 42.0 mm. There were no significant differences in these distances when comparing left with right, or cases with controls. Weak correlation was found between the urethra-to-obturator foramina distances and heights only in the case subjects.
There is high variability in the distance from mid-urethra to the obturator foramina. Height should not be used as a predictor of dimensions in the lesser pelvis.
评估从尿道中部到闭孔的距离，并探讨骨盆尺寸与身高之间的相关性。
这是一项关于压力性尿失禁机制的母本病例对照研究的二次分析。我们在有（病例组，n = 50）和无（对照组，n = 50）压力性尿失禁的女性的磁共振图像上测量了骨盆尺寸。
病例组中从尿道中部到闭孔膜的平均距离，左侧为31.8毫米，右侧为32.1毫米，范围为25.9至42.0毫米。比较左右两侧或病例组与对照组时，这些距离无显著差异。仅在病例组中发现尿道到闭孔的距离与身高之间存在弱相关性。
从尿道中部到闭孔的距离存在高度变异性。身高不应被用作小骨盆尺寸的预测指标。
