The aim of this randomized controlled study is to compare the pain experienced during extraction of retained IUD by office hysteroscopy with the pain experienced during extraction of retained IUD under ultrasound guidance . Moreover, the success of both procedures was compared. Various subgroups (patients who delivered only by Caesarean section, patients who delivered virginally, nulliparous women and menopausal patients) in both groups are compared.

The intrauterine device (IUD) is a commonly used long-acting, effective and reversible method of contraception. The recommended way to remove a IUD is by grasping the threads with forceps and applying gentle traction until the IUD is extracted from the external os.

Absent of the threads at the time of IUD removal is reported in 4.5 to 18% of cases. If the IUD is present in the uterus and threads are not visible , its removal in the office setting can still be achieved in about 80% of patients with the use of alligator forceps or string retrieval devices, hooks or clamps. However, blind manipulation may cause uterine perforation . In cases where such devices have failed (retained IUD ), If in office extraction of IUD by these instruments failed, removal of this retained IUD in the operating room is often employed because cervical dilatation and regional or general anesthesia are needed.

In the last decade, several studies reported in office extraction of retained IUD by office hysteroscopy or under ultrasound guidance. No studies compared the efficacy or safety of these procedures
