Overactive bladder (OAB) can frequently exert a negative effect on female sexual function. Mirabegron, a β3 receptor agonist, improves OAB symptoms, but there are very few information about its role on female sexual dysfunction (FSD). Aim of the study was to assess the impact of Mirabegron on FSD in women affected by OAB.
Fifty sexually active women suffering from idiopathic OAB were included in the study. Patients were assessed by means of a urogynecologic physical examination and were asked to complete the 3-day voiding diary, the International Consultation on Incontinence Questionnaire- Short Form (ICIQ-SF), the Female Sexual Function Index (FSFI) questionnaire and VAS, before and 12 weeks after treatment with Mirabegron. In addition, at the same time points, patients underwent uroflowmetry with the measurement of post- void residual volume (PVR).
At baseline all patients were affected by OAB symptoms, with 49/50 patients (98%) presenting with FSD. At 12- weeks follow- up, OAB symptoms improved significantly in all patients, with 59.5% of subjects achieving a complete urinary continence. FSFI Total Score significantly improved in 42/50 patients (84%) from 18.9 ± 4.3 to 21.8 ± 4.5 (p < 0.0001). Sixteen cases (32%) presented with no FSD. Also mean ± SD scores of ICIQ-SF and VAS significantly improved (from 17.1 ± 5 to 7.9 ± 4.8 and from 3.9 ± 1.2 to 6.9 ± 1.2 respectively, p < 0.000).
Mirabegron not only is able to control urinary symptoms in women with OAB, but also induces a significant improvement in their sexual life.
