The levonorgestrel-releasing intrauterine system (LNG-IUS) has been used in the treatment of both idiopathic menorrhagia and adenomyosis. An electronic search of the on-line medical literature revealed no reports of its use for menorrhagia secondary to uterine myomas. Presented here is the successful treatment of uterine myomas with menorrhagia in a woman with a renal transplant. There was a significant reduction in menorrhagia, dysmenorrhea, and uterine and myoma size with the use of the LNG-IUS. We believe that this system provides an alternative to conventional hysterectomy and gonadotrophin-releasing hormonal analog medical treatment for uterine myomas, with a possibly inhibitory effect on myoma growth.
