摘　　要：目的 :探讨磁共振成像在女性压力性尿失禁 (SUI)中的应用价值。方法 :对临床确诊为SUI的 2 0例患者 ,根据临床表现将SUI分为 3度 :Ⅰ度 5例、Ⅱ度 9例、Ⅲ度 6例。分别在自然状态下和应力 (增加腹压 )状态下行MRI ,采用真稳态进动梯度回波 (B FFE)技术行膀胱尿道矢状面成像。测量膀胱尿道连接点至耻尾线的垂直距离 ,结果与 10例正常对照者进行比较。结果 :自然状态时所有病例的膀胱尿道连接点均位于耻尾线以上 ,SUI患者与对照组之间无显著性差异。应力状态时 ,2 0例SUI患者膀胱尿道连接点均有不同程度下降 ,其中 18例下降至耻尾线以下 ,平均下移距离为(2 5 .0 8± 3 .3 1)mm ;10例正常对照组平均下移距离为 (12 .5 2± 1.62 )mm。两组间差异有显著性意义 (P <0 .0 0 1)。结论 :MRI能显示膀胱尿道的解剖结构及功能状态 ,能比较准确地诊断SUI。Objective:To discuss the value of MRI in evaluation of female stress urinary incontinence (SUI).Methods:20 cases of clinically proved SUI were cullected,SUI was divided into three grades according to the clinical appearances,Ⅰ° in 5 cases、Ⅱ° in 9 cases and Ⅲ° in 6 cases.MRI was performed under natural and stress condition.The distance between the pubococcygeal line and urethra-vesical junction was measured in all 20 patients with SUI and the values of distance were compared with those of 10 healthy controls.Results:In natural condition the urethra-vesical junction laid above the pubococcygeal line.The difference in distance between SUI group and control group is not significant.Urethra-vesical junction descented in 20 cases of SUI in stress,18 of all cases was under pubococcygeal line,but did no in other patients and all of healthy controls.The distance of descenting was (25.08±3.31)mm and (12.52±1.62)mm in group SUI and control,respectively.There was higher signficant difference between group SUI and control.Conclusion:MRI is valuable to reveal anatomic structure and function of badder and urethra and helpful for evaluation of SUI.
