Evaluation of patients with uterine perforation after intrauterine device placement and determination of risk factors: A Retrospective Case-Control Study

The occurrence of uterine perforation due to IUDs can result in contraceptive failure; and adhesion, fistulas, infection, abscess, and the perforation of the surrounding blood vessels, intestine, and bladder due to the migration of the IUD to the peritoneal cavity after uterine perforation (11). Material and Methods This retrospective case control study included 22 patients with uterine perforation after IUD placement (patient group) who were diagnosed and surgically treated in the Gynecology and Obstetrics Clinic of a university hospital between January 2012-March 2020 and 30 control patients with IUDs without any complications. The patient group included patients in whom an IUD was not seen in the endometrial cavity and an IUD string was not seen in the cervical ostium on vaginal examination, patients with an IUD found outside the endometrial cavity in the uterine myometrium, serosa or the abdomen, and patients who were operated; the control group included patients whose IUDs were in place in the endometrial cavity with an IUD string visible in the cervical ostium on vaginal examination. Factors determined to be significant regarding the risk of IUD translocation were subjected to multiple linear regression analysis to determine whether they were influenced by parity.
