Follow-up checkups with uterotubography in 84 cases for 1~ 3 months ( mean, 2.3 months) found a patent rate of both oviducts of 82.1% ( 69/ 84). 84例保留输卵管者随访1~3个月,平均2.3月,子宫输卵管造影双侧输卵管通畅率为82.1%(69/84)。
Conclusion: The digital subtraction method with high-pressure auto-injector could improve the quality of uterotubography image. 结论:采用数字减影与高压注射器行子宫输卵管造影能提高造影质量。
