The continuous use of active hormonal contraceptives by insertion of intrauterine system releaser of progestational agent (Levonorgestrel) has been very useful due to its desired contraceptive action as well as its positive effect for managing of some gynecological affections including endometriosis, uterine fibromatosis and certain menstrual dysfunctions and adding recently new indications. OBJECTIVE: To assess the usefulness of the intrauterine releaser system Lovenorgestrel (Mirena) in management of metrorrhagies and other gynecological affections. METHODS: A descriptive, longitudinal and prospective study was conducted including 19 patients underwent Mirena insertion to treatment metrorrhagies and other gynecological affections between January 1, 2003 and December 31, 2008. Patients included in study were half-yearly assessed by interviews, clinical examination, hematology studies and echography. RESULTS: There was a market reduction of menstrual flux; those patients with more than 12 months of use had an increase of 1 ½ gr in first figures of hemoglobin. Patients presenting with myomata achieved a slight reduction of tumor and a metrorrhagies control also verifying a decrease in cystic masses and in symptoms of patients with endometriosis, while it was possible to obtain a linear endometrium in patients under hormone replacement therapy (HRT). CONCLUSIONS: More frequently reported adverse effects were those related to local action of progestogen on endometrium e.g. spotting and amenorrhea. As exception were the lower extremities cramps. Until now no patient has interrupted the use of Mirena.
