[目的]探讨宫腔压力值与双侧输卵管通畅情况的相关关系,确定合理的压力截断值作为输卵管通畅情况的诊断标准。[方法]采用输卵管通液仪进行子宫输卵管造影诊断550例不孕女性输卵管通畅情况,在恒定的速度下测试注液压力值,绘制ROC曲线确定压力截断值以诊断输卵管的通畅情况。[结果]通过压力诊断输卵管通畅情况可分为:(1)“双侧通畅”;(2)“双侧不完全通畅”;(3)“一侧不通,另侧通而不畅”;(4)“双侧不通”。(1)与(2)压力诊断截断值为16.75kpa,对应的灵敏度80%,特异度80%,(2)与(3)压力诊断截断值22.20kpa,相应灵敏度80%,特异度62%,(3)与(4)压力诊断截断值为27.30kpa,相应灵敏度95%,特异度80%。[结论]宫腔压力值可作为诊断输卵管通畅情况的参考指标。
[Objective] To investigate the relationship between uterine pressure and bilateral tubal patency, and to determine the reasonable value of pressure cutoff as the diagnostic criteria for tubal patency. [Method] The oviduct tubal catheterization was used to diagnose tubal patency in 550 infertile women. The injection pressure was measured at a constant speed. The ROC curve was drawn to determine the pressure cutoff to diagnose tubal patency. [Results] The diagnosis of tubal patency by pressure can be divided into: (1) “bilateral patency ”; (2) “bilateral imperfect patency ”; Poor “ (4) ” bilateral barrier ". (1) and (2), the corresponding diagnostic sensitivity is 80%, the specificity is 80%, (2) and (3) the pressure diagnostic cutoff is 22.20kpa, the corresponding sensitivity is 80% and the specificity is 62% (3) and (4) The pressure diagnosis cut-off value is 27.30kpa, the corresponding sensitivity of 95%, specificity of 80%. [Conclusion] The value of uterine pressure can be used as a reference index for the diagnosis of tubal patency.
