【摘要】 目的对比分析盆底功能障碍性疾病(pelvic floor dysfunction,PFD)患者及正常女性盆底解剖结构的MRI表现。方法选取我科2012年6月至2014年6月确诊为PFD的患者40例。同时选取健康同龄女性志愿者40例作为对照组。通过行静动态核磁共振扫描(MRI)评价两组的肛提肌指标、盆腔各器官脱垂情况、尿道长度和尿道周围支持结构指标。结果PFD组耻尾肌面积、髂尾肌面积和耻直肌面积的静/动态测量值显著低于正常组。PFD组提肌板角、盆膈裂孔横径、LH线和M线的静/动态测量值分别为,显著高于正常组的。PFD组静态和动态期的膀胱颈、子宫颈和肛直肠连接均显著重于正常组,P<0.05。结论 PFD患者在MRI所成图像中盆底解剖结构和正常女性差异较大,盆腔动静态磁共振在PFD诊断和评估中具有重要应用价值。更多还原

【Abstract】 Objective The MRI manifestations of pelvic floor dysfunction(PFD) and normal female in pelvic anatomy were compared. Methods 40 patients diagnosed PFD in our department from June 2012 to June 2014 were selected, including 20 cases of pelvic organ prolapse, urinary incontinence seven cases, the combined 13 cases. Meanwhile 40 healthy female volunteers at the same age were chosen as the control group. By line static and dynamic MRI scans(MRI) evaluation of the levator ani muscle groups indicators pelvic organ prolapse, the urethral length and support structures around the urethra indicators. Results PFD group shame tail muscle area, static / dynamic measurements iliac tail area and shame rectus muscle area were(2.12±0.43) cm2 /(1.76±0.37) cm2,(1.96±0.55) cm2 /(1.63±0.48) cm2 and(2.29±0.64) cm2 /(1.87±0.53) cm2, significantly lower than the normal group(2.69±0.57) cm2 /(2.68±0.49) cm2,(2.43 ±0.61) cm2 /(2.39±0.40) cm2 and(2.77±0.39) cm2 /(2.81±0.36) cm2. PFD group levator plate angle, pelvic diaphragm hole diameter, LH line and M-line static / dynamic measurement values were significantly higher than the normal group PFD set of static and dynamic phase of the bladder neck, cervix and anorectal connections are significantly focused on the normal group, P<0.05. Conclusion PFD patients have different MRI images in the pelvic floor anatomy with normal female. In pelvic static and dynamic magnetic resonance PFD has important applications in the diagnosis and assessment.更多还原
