Assessment of -T-380A and Levonorgestrel-Releasing Intrauterine Device Types in Terms of Partial and Complete Expulsion

Purpose: Intrauterine Devices (IUD) are among commonly used reversible contraceptive methods. The aim of this study is to compare the spontaneous expulsion rates and other factors of these two IUD types. Material and Method: Our study was conducted retrospectively in our hospital by recording the age, gravida, parity, IUD types; existence of expulsion, its being partial or complete and other relevant data of the patients who received copper IUD (Cu-T380A) and LNG-releasing IUD (Mirena). Findings: The data of 2215 patients who used Copper IUD, and the data of 400 patients who used LNG-Releasing IUD were included in the study. Expulsion was detected in 234 patients (10,6%) who used Copper IUDs, and in 34 patients who used LNG-releasing IUDs (8,5%). It was observed that the mean age, gravida and parity values were bigger in the group who used LNG (mean age: 34,5 ± 7,1 vs 42,47 ± 6,200, p <0,001; gravida: 2,62 ± 1,19 vs 3,04 ± 1,15, p<0,001; parity: 1,96 ± 0,780 vs 2,24 ± 0,81, p <0.001). It was also determined that the mean age values of the LNG-releasing IUD patients who experienced expulsion were bigger than the patients with copper IUD (34,5 ± 7,1 vs 42,47 ± 6,200, p < 0.001). Moreover, the complete expulsion rate was observed as (9 (%2,8) vs 13 (%38,2), p <0.001) in patients who used LNG-releasing IUD. Result: In our study it was determined that the complete expulsion rate in LNG-releasing IUDs was more. This difference may be stemming from the fact that the experience on using the LNG-releasing IUDs being less than the copper IUDs.
