Abstract: Background: To study the efficacy of levonorgestrel intrauterine system (LNG-IUS; Mirena) in conservative management of abnormal uterine bleeding (AUB). Objective: To determine the effectiveness of Levonorgestrel releasing intrauterine system (Mirena), in decreasing the menstrual blood loss, dysmenorrhea and dyspareunia at the end of one year after insertion. Materials & Methodology: This observational study was carried out on 43patients done in tertiary care hospital,Rajahmundry over 1 year between 2021 to 2022. A detailed general, systemic, pelvic (to see for Mirena threads), and breasts examination was done at every visit. Follow-up ultrasound was done at every visit to see forMirena location and if there were any changes in the original pelvic pathology or development of a new pathology like ovarian cysts. Hemoglobin (Hb) estimation was done after 1 year. Results: Out of 43 patients studied most common reason for mirena insertion being AUB (53.4%), endometriosis (23.2%), adenomyosis (13.9%) and fibroid uterus (9.30%). Common symptoms for mirena insertion being menorrhagia(62.7%), dysmenorrhea 13 ( 30.2 %) and dyspareunia 3( 6.9%).The majority of women having irregular cycles (74.41%), regular cycles ( 25.58 %).The patterns of bleeding post mirena insertion was shifted to amenorrhea( 48.8%) followed by regularized cycle with reduced flow (37.20% )and irregular cycles with reduced flow (13.9%) The major side effect noticed post mirena insertion is weight gain in 55.8% followed by spotting ( 30.2 %) ,breast tenderness ( 9.3 %) and pelvic pain (4.6%) Conclusion: Levonorgestrel-releasing intrauterine systemna provides an incredible nonsurgical alternative in treatment of abnormal uterine bleeding, adenomyosis, endometriosis, endometrial hyperplasia.Its effects are reversible and it also an effective contraceptive.
