摘要
目的分析女性压力性尿失禁MRI影像学特征。方法回顾分析我院32例压力性尿失禁女性患者临床资料,作为观察组,患者均予以闭孔尿道吊带术治疗,同时以20例无压力性尿失禁的患者为对照组,研究对象均进行MRI检测,记录两组对象的尿道括约肌形态变化,治疗1周后进行MRI检查,分析所有研究对象的尿道括约肌、膀胱尿道后角及尿道倾斜角的变化情况,统计膀胱漏斗阳性发生率。结果静息状态下观察组尿道中段外括约肌厚度(2.24±0.45)mm,显著低于对照组(2.73±0.56)mm(P<0.05);静息状态下功能尿道长度为(2.71±0.41)cm,显著低于对照组(2.96±0.47)cm(P<0.05),屏气用力状态下功能尿道长度两者的功能尿道长度无统计学意义(P<0.05);静息状态及屏气用力状态下,观察组的膀胱尿道后角、尿道倾斜角均显著高于对照组(P<0.05),观察组18例膀胱漏斗阳性,且在屏气状态下更为明显;但观察组经手术治疗后,各指标均与对照组无统计学意义(P<0.05)。结论 MRI能有效反映压力性尿失禁患者尿道周围支持结构及尿道活动性等变化,可用于女性压力性尿失禁的诊断及手术疗效评估。
Objective To analyze the MRI findings of stress urinary incontinence(SUI)in female.Methods The clinical data of 32 female patients with SUI in the hospital were analyzed retrospectively.They were included into the observation group and were treated by transobturator supraubc arch sling.Another 20 patients without SUI were included in the control group.All subjects were examined by MRI,and the morphological changes of the urethral sphincter in the two groups were recorded.The MRI test was performed after1 week of treatment.The changes of urethral sphincter,posterior urethra-vesical angle and urethral inclination angle were analyzed,and the incidence rate of bladder funnel was analyzed statistically.Results The resting-state thickness of external sphincter of the middle urethra and urethral length in the observation group were significantly smaller than those in the control group[(2.24±0.45)mm,(2.71±0.41)cm vs(2.73±0.56)mm,(2.96±0.47)cm](P<0.05).There was no statistically significant difference in functional urethral length between the two groups under breath holding state and forcing state(P<0.05).The posterior urethra-vesical angle and urethral inclination angle in the observation group were significantly larger than those in the control group under breath holding state and forcing state(P<0.05).There were 18 cases of positive bladder funnel in the observation group,and they were more obvious under the breath holding state.After operation,there was no significant difference between the two groups in the indexes(P<0.05).Conclusion MRI can reflect the changes of urethral support structure and urethral mobility in patients with SUI.
