Abstract
The most common indications for Levonorgestrel intrauterine device (LNG-IUD) are contraception and management of abnormal uterine bleeding (AUB). This study was conducted with the aim of exploring the differences in the clinical profile and outcome of women using LNG-IUD for contraception and AUB. This was a retrospective comparative cross-sectional study of women who underwent LNG-IUD (52 mg) between 2012 and 2017. Their electronic health records were reviewed until the last documented follow-up or until December 2021. A total of 235 women had LNG-IUD with an age range of 21 to 62 years and a mean of (37.98 years±6.76). Of these women, 153/235 (65.1%) had it for contraception and 82/235 (34.89%) had it for AUB. The follow-up was 1-94 months with (mean ± SEM) follow-up for the AUB group of (21.48±2.31) months and for contraception group was (20.74±1.76) months (p-value of 0.80). There was a significant difference between the two groups in the age and body mass index (BMI), where women who had LNG-IUD for AUB were older (mean of 42.54±6.49 years, p-value <0.001) and had higher BMI (31.88±7.52 kg/m2, p-value =0.011). All LNG-IUDs that were indicated for contraception were inserted in an outpatient setting. However, 68.3% in the AUB, the insertion was in the operating theater in conjunction with hysteroscopy. After combining both expulsion and removal of LNG-IUD during the follow-up period, there was no significant difference between the 2 groups in the overall retention rate during the follow-up (p-value =0.998). this study shows that women using LNG-IUD for the management of AUB are older and have a higher BMI compared with those using it for contraception. AUB women experienced more expulsion compared with the contraception group, but there was no difference between the 2 groups in the overall survival/retention of LNG-IUD.
