The clinical effect of dienogest on urinary and sexual symptoms in endometriosis patients.

Background: To evaluate the effect of dienogest on urinary symptoms and sexual functioning within a 6-month follow-up period.

Methods: We recruited 22 women with symptoms with dysmenorrhea, deep dyspareunia, and dyschezia accompanied with irritative urinary symptoms including frequency and urgency at Kaohsiung Medical University Chung-Ho Memorial Hospital from 2017 Jan 1 to 2019 Jan 1. The diagnosis of endometriosis mainly focused on vaginal examination and transvaginal ultrasound was performed in each patient. The participating patients took a daily dose of 2 mg Dienogest and underwent outpatient visits at the beginning, 1, 2, 3, and 6 months following treatment.

Results: Our data showed a significant improvement in the visual Analog Scale (VAS) score from the first month till the sixth month after DNG treatment. The Overactive Bladder Symptom Score (OABSS), Urogenital Distress Inventory (UDI-6), and Incontinence Impact Questionnaire (IIQ-7) were significantly improved after the DNG treatment. Besides, serum estradiol was also decreased. Our data also showed that DNG treatment for 6 months did not affect Female Sexual Function Index (FSFI) score. Some patients with heavy menstruation also improved; however, some patients with regular periods missed or skipped a period after DNG treatment, while other adverse effects were also observed.

Conclusion: Our study demonstrated that DNG could not only alleviate endometriosis pelvic pain but reduce urinary symptoms within the 6-month follow-up as well. DNG did not affect sexual function as measured by the FSFI score, although some adverse effects were recorded.
