Case-control study on related factors leading to difficulty in removing devices after menopause
Objective To exploring the related factors of difficulty in obtaining intrauterine devices in postmenopausal women.Methods 980 postmenopausal women who underwent device retrieval were selected as the study subjects,and the retrieval process was used as the grouping basis.Among them,postmenopausal women with difficulty in device retrieval were set as the study group,and postmenopausal women with successful device retrieval were set as the control group.Compare the relevant indicators between two groups of women.Results Among 980 postmenopausal women,834(85.10％,834/980)underwent successful removal of devices;135 cases(13.78％,135/980)had difficulty in retrieving instruments;11 cases(1.12％,11/980)failed to retrieve the device.Logistic regression analysis showed that factors leading to difficulty in retrieving an intrauterine device were placement time ≥20 years,placement after induced abortion,age ≥55 years,and O-shaped contraceptive device(P＜0.05).Conclusion The incidence of difficult retrieval after menopause is high,and there are many influencing factors.Targeted measures should be implemented to reduce the difficulty of retrieval and avoid retrieval failure.
