Abstract: Objective：To evaluate the risk factors and surgical treatment for patients suffered from intrauterine devices（IUD）translocation. Methods：A case–control study was carried out between Cases (40 women with IUD translocation) and controls (40 women with an IUD in normal location suffered from other gynecologic disease（ovarian cyst）at the same period) were recruited. Results：Making comparison between the ectopic group and control group, the age, the ranking of the hospital, the type of IUDs and the duration of IUD usage were no statistical difference (P>0.05).The risk factors IUD translocation were related to the experience of operative skills, the time of IUD insertion and complicated with fibroma(P<0.05).The IUDs in 8 women (20% ) were embedded into the endometrial and muscular layer; 32 (80% ) had migrated outside the uterus. All the patients received surgery. Ectopic IUD were removed successfully by hysteroscopy in 6 patients; 6 of the patients were removed through colpotomy; 10 patients were managed by laparoscopy, whereas laparotomy was required in 16(40%) The removal rate is 100%.Conclusion The risk factors may include inexperience of operative skills, the time of IUD insertion and complicated with other diseases of the uterus. Considering the location of translocated IUDs, in the present study, hysteroscopy, posterior colpotomy, laparoscopy or laparotomy should be considered according to different locations of the IUDs.
