Purpose
To investigate the effects of onabotulinum toxin type A (Onabot/A) intravesical injections on urinary and sexual function in a group of patients affected by multiple sclerosis (MS).
Methods
We enrolled 31 MS female patients with symptoms of overactive bladder and detrusor overactivity. All patients underwent urodynamics and were administered 3-day voiding diary, Incontinence Quality of Life (I-QoL) questionnaire, Female Sexual Function Index (FSFI) questionnaire, Hamilton Anxiety Rating Scale (HAM-A) and Hamilton Depression Rating Scale (HAM-D) before and 3 months after Onabot/A intravesical injection.
Results
Onabot/A injection significantly improved urinary symptoms as shown by the 3-day voiding diary, I-QoL questionnaire and the urodynamic variables. In addition, it also significantly improved sexual functioning in continent patients and psychological status as demonstrated by the increase in FSFI, HAM-A and HAM-D scores.
Conclusions
The Onabot/A-induced positive effect on sexual dysfunction in our MS patients is likely due to an indirect effect exerted by the overall urological clinical improvement on sexual function at both the psychological and emotional levels. The positive effect exerted by Onabot/A on the anxiety and depression scale also suggests that urinary symptoms have a negative impact on the psychological status of the patients.
