盆底超声在产后早期压力性尿失禁中的运用与可行性

Application and feasibility of pelvic floor ultrasound in early postpartum stress urinary incontinence

目的研究与分析盆底超声在产后早期压力性尿失禁中的运用及其可行性。方法选取2016年1月至2017年1月收治的产后早期压力性尿失禁患者50例为观察组对象,选择同期正常产后妇女50例为对照组。两组均接受盆底超声检查。观察比较两组在300 ml膀胱容量下尿道内口形成率、膀胱颈旋转角(θ)、尿道膀胱后角(Ar、As)、膀胱颈至耻骨联合中点的距离(Br、Bs)和膀胱颈移动度(Mu)。结果两组在指导下完成Valsalva动作的情况均较好,且超声图像质量较高,可清晰显示静息状态下以及Valsalva动作下盆腔器官的位置、功能等变化。观察组在300 ml膀胱容量下尿道内口形成率、θ、Ar、As、Br、Bs、Mu数值均显著高于对照组,差异有统计学意义(P均<0.01)。观察组尿道内口形成率为86.0%(43/50),显著高于对照组的12.0%(6/50),差异有统计学意义(P<0.01)。结论盆底超声运用于产后早期压力性尿失禁的诊断,能提供客观的影像学资料,具有较高的可行性。

Objective To investigate the application and feasibility of pelvic floor ultrasound in early postpartum stress urinary incontinence（SUI）. Method Fifty cases of early postpartum SUI patients were selected as study group, and 50 cases of normal postpartum women in the same period were selected as control group. Pelvic floor ultrasound examination was taken in both groups. The incidence of internal urethral orifice, bladder neck rotation angle （0）, posterior urethral bladder angle （At, As）, bladder neck to pubic symphysis midpoint distance （Br, Bs） and bladder neck mobility （Mu） in two groups were observed and compared when the bladder capacity was 300 ml. Results Under guidance, the Valsalva motion performed well in patients of both groups, thus the quality of the ultrasound images was higher, which could clearly display the location and function of pelvic organs under resting state and Valsalva action. The 0, Ar, As, Br, Bs, Mu in study group were all higher than those in control group （all P 〈0.01 ）. The incidence of internal urethral orifice in study group was higher than that in control group [ 86.0% （43/50） vs 12.0% （ 6/50）, P 〈 0.01 ]. Conclusion Pelvic floor ultrasound examination could be used in the diagnosis of early postpartum SUI, which could provide objective imaging data with high feasibility.
