The objective was to evaluate the cross-sectional area (CSA) and the Doppler velocimetric parameters of the levator ani muscle vessels in premenopausal women with and without urinary stress incontinence.
Sixty-three premenopausal women constituted three groups: GI (nulliparous), GII (continent multiparous), and GIII (incontinent multiparous). The patients had undergone transperineal ultrasound in which the CSA was measured and Doppler velocimetry was performed. The examination was repeated by a second observer using the same procedure.
There was a statistically significant correlation between the measurements of the observers I and II regarding all the parameters studied, except for the A/B ratio in GIII. The CSA was significantly greater in GI and GII than in GIII. As far as Doppler velocimetry is concerned there were no differences in the Doppler velocimetric indices among the three groups. Concerning the absent end diastolic shift, it was observed that there was a significantly greater incidence of such findings in GI+GII (continent women) towards GIII (incontinent women).
The CSA evaluation and the Doppler velocimetry of the levator ani muscle vessels were highly reproducible. The CSA was higher in continent women and the frequency of the absent end diastolic shift was higher in incontinent women.
评估有和没有压力性尿失禁的绝经前女性肛提肌血管的横截面积（CSA）和多普勒测速参数。
63名绝经前女性组成三组：GI组（未生育）、GII组（无尿失禁经产妇）和GIII组（有尿失禁经产妇）。患者接受了经会阴超声检查，测量CSA并进行多普勒测速。由第二名观察者使用相同程序重复检查。
除GIII组的A/B比外，观察者I和II对所有研究参数的测量结果之间存在统计学显著相关性。GI组和GII组的CSA显著大于GIII组。就多普勒测速而言，三组之间的多普勒测速指标没有差异。关于舒张末期血流信号缺失，观察到GI+GII组（无尿失禁女性）中出现此类发现的发生率明显高于GIII组（有尿失禁女性）。
肛提肌血管的CSA评估和多普勒测速具有高度可重复性。无尿失禁女性的CSA较高，有尿失禁女性舒张末期血流信号缺失的频率较高。
