子宫输卵管造影术逆流相关因素分析

目的：研究子宫输卵管造影(HSG)术中产生逆流的相关因素，提高对子宫输卵管造影术中逆流的认识。方法选择因不孕症行 HSG 术的180例患者，对其中63例造影过程中发生逆流的患者进行分析。结果经单因素分析得出原发/继发不孕、月经干净天数、输卵管阻塞与否及插管深度4个变量与逆流具有相关性，经 Logistic 回归分析表明月经干净天数、输卵管阻塞与否及造影操作中插管的深浅有密切相关性。结论逆流是月经干净天数、输卵管阻塞与否、插管操作多种综合因素作用的结果，因此可在术前、术中做好充分准备，减少逆流的发生。

Relevant factors analysis of hysterosalpingography countercurrent

Objective To study on the factors of countercurrent occured in hysterosalpingography to improve the understanding of countercurrent.Methods 180 patients who underwent hysterosalpingography due to infertility were recruited,and 63 of them who were involved in countercurrent in the process of hysterosalpingography were analyzed statistically.Results The single factor analy-sis demonstrated that such four factors of primary/secondary infertility,menstrual clean days,tubal obstruction or not,and depth of cannula were associated with countercurrent,while Logistic regression analysis indicated that the factors of menstrual clean days, tubal obstruction or not,and depth of cannula during the hysterosalpingography operation were closely related.Conclusion Counter-current are caused by the comprehensive impact of several comprehensive factors like menstrual clean day,tubal obstruction or not, and cannula operation.Therefore adequate preparation should be made before and during the operation,to reduce the occurrences of countercurrent.
