ABSTRACT
Objective: The aim of this study is to document the preoperative evaluation techniques of mislocated intrauterine device (IUD) patients and discuss the optimal management of these cases. Material and Methods: This study was conducted between January 2016 and October 2021 at an obstetrics and gynecology department of a tertiary center. A total of 25 patients presenting with mislocated IUDs were retrospectively analyzed. Demographic findings, diagnostic and preoperative evaluation methods, and operation notes were collected from the patients' files and hospital patient information programs. Results: Every patient had initially undergone a preoperative gynecologic examination and transvaginal ultrasonography (TVUSG). After TVUSG, other preoperative techniques were used alone or in combination according to each finding and need of further technique. Plain radiography, hysteroscopy, computed tomography (CT), magnetic resonance imaging (MRI), and colonoscopy were the techniques used. Of the 25 patients with missing IUDs, it was observed that 23 had successful removal of their IUDs. All but two of the patients were operated on laparoscopically. Conclusion: In cases of mislocated IUDs, all patients should undergo a vaginal examination and TVUSG. Although ultrasonography and radiography are the basic diagnostic techniques; radiography, hysteroscopy, CT, MRI, and colonoscopy are the techniques that can be used according to each case's condition. For these patients, laparoscopy was the first line of therapy.
