Several approaches for treating severe uterine cervical stenosis after conization for cervical intraepithelial neoplasia have been reported; yet, the condition can still be difficult to treat successfully. We performed uterine cervical dilation surgery in two patients with severe stenosis, followed by insertion of the levonorgestrel-releasing intrauterine system, which is used for dysmenorrhea or endometriosis-related pain because of its strong progesterone activity. Patient 1 was a 34-year-old Japanese woman who was diagnosed with dysmenorrhea caused by recurrent uterine cervical stenosis and hematometra after laser conization. Patient 2 was a 44-year-old Japanese woman who developed dysmenorrhea and prolonged menstruation caused by uterine cervical stenosis without hematometra. After providing informed consent, they underwent cervical dilation surgery followed by insertion of the levonorgestrel-releasing intrauterine system. After treatment, their symptoms immediately improved, and after removal of their devices, they remained asymptomatic. To the best of our knowledge, this is the first report to confirm the usefulness and easy applicability of the levonorgestrel-releasing intrauterine system for uterine cervical stenosis. Although we had success with the method, this study of two patients is preliminary. Further study with larger numbers of patients is necessary to confirm the usefulness of our technique.
