摘　　要：目的:本研究旨在比较妊娠中、晚期孕妇经会阴盆底二维超声的表现特点,为研究妊娠与压力性尿失禁之间的关系提供影像学依据。方法:对孕龄为14~40周的74例中晚期单胎妊娠孕妇为研究对象,将其分为尿失禁组(34例)和无尿失禁组(40例)。均接受静息状态和最大Valsalva动作时的经会阴盆底二维超声检查。观察指标有:膀胱颈角度、膀胱颈旋转角度、膀胱颈活动度、膀胱尿道后角、尿道旋转角度。进行独立样本t检验、偏相关分析。P<0.05认为有统计学意义。结果:(1)中晚期妊娠尿失禁组的膀胱颈旋转角度、膀胱颈活动度以及最大Valsalva动作时的膀胱颈角度、膀胱尿道后角均大于无尿失禁组,其差异均有统计学意义(均P<0.05)。(2)中晚期妊娠尿失禁组的尿道旋转角度与孕周呈中度相关,差异有统计学意义(P<0.05)。结论:患有SUI的中晚期妊娠孕妇膀胱尿道周围支持结构有明显改变,尿道旋转角度随孕周的增大而增加。Objective To investigate the characteristics of transperineal pelvic uhrasounds among middle-late gestational women and study the the correlation between middle-late gestation and stress urinal7 incontinence. Methods Seventy-four pregnant women at a gestation of 14-40 weeks were divided into the incontinence group （n = 34） and the non-incontinence group （u = 40）. The bladder neck angle, the bladder neck rotation angle, the bladder neck movement degrees,the posterior urethra-vesieal angle, and the urethral rotation angle at both inactivity and maximum Valslva activity were evaluated by pelvic ultrasound. The acquired data were treated and analyzed with t-test and correlation analysis with with P 〈 0.05 considered statistically significant. Results Compared with the non-incontinence group, the bladder neck rotation angle, BND, bladder neck angle and posterior urethra-vesical angle during the maximum Valsalva activity in the incontinence group were all significantly larger （P 〈 0.05）. A moderate correlation between urethral rotation angle and gestation week in the incontinence was observed （P 〈 0.05）. Conclusion The changes of the supportive structures around bladder urethreal tissues in middle-late gestation women are obvious. The urethral rotation angle becomes larger with the gestation going on.
