GyneFix IUD Plus LNG-IUS for Adenomyosis

Brief Summary

Adenomyosis is a common gynecological condition that can cause menstrual pain, heavy menstrual bleeding, anemia, and reduced quality of life. The levonorgestrel-releasing intrauterine system is commonly used as a conservative treatment, but displacement or expulsion of the device may occur, especially in patients with an enlarged uterus or a deep uterine cavity. This study evaluated whether combining an Indomethacin-GyneFix intrauterine device with a levonorgestrel-releasing intrauterine system could improve device stability in patients with adenomyosis. Eligible participants were randomly assigned to receive GyneFix IUD plus LNG-IUS, ring IUD plus LNG-IUS, or LNG-IUS alone. Participants were followed for 6 months after device placement. The main outcome was device displacement or expulsion at 6 months. Other outcomes included menstrual pain, menstrual blood loss, uterine volume, hemoglobin, CA125, adverse events, and treatment acceptance.
