Twelve-year experience of office-setting removal of lost intrauterine devices in place for more than 10 years.

Objective: We investigated the effectiveness of removing lost intrauterine devices (IUDs) that had been in place for over 10 years, using Lin's biopsy grasper in an office setting. Methods:This single-centre, retrospective study conducted between March 2006 and June 2018 included 49 women who had had an IUD in place for contraception for more than 10 years and who underwent removal of the lost IUD using Lin's biopsy grasper under transabdominal sonography without use of a tenaculum, anaesthesia and analgesia, after dilation of the cervical os and hysteroscopy. Results: The women's median age was 52 years (range 34-80 years) and the median duration of insertion was 17 years (range 10-43 years). Forty-eight (98%) women had their lost IUD removed using Lin's biopsy grasper. Among the removed IUDs, there were eight FD-1 IUDs with a string, 13 FD-1 IUDs without a string, 13 Chinese IUDs, seven Ota ring IUDs, three KS ring IUDs, two Saf-T-Coil IUDs, two Lippe loop IUDs and one Wing IUD. All women tolerated the procedure and there were no major operative complications. Conclusions: Lin's biopsy grasper was effective in removing IUDs that had been in place for a long time.
