Abstract

Hypothesis / aims of study
The correlation between changes in sexual function and improvements in LUTD in patients treated with OnabotulinumtoxinA (onaBoNT-A) detrusor injection is unclear and limited only to women with neurogenic OAB. Aim of this study was to evaluate the impact of OnabotulinumtoxinA (onaBoNT-A) injection on sexual function in women undergoing this treatment for idiopathic wet overactive bladder (OAB).
Study design, materials and methods
This is a pilot three-center observational study including women affected by idiopathic wet overactive bladder refractory to standard conservative treatments and underwent onaBoNT-A injection. Sexuality was assessed using the Female Sexual Function Index (FSFI) Italian version.1 A 3-day voiding diary, OAB screener questionnaire (OAB-S), and the international consultation on incontinence questionnaire short form (ICIQ-sf) were completed before and 3 months after onaBoNT-A injection to evaluate OAB symptoms.
Results
All the 32 enrolled patients were evaluable and included for statistical analysis. Mean age ws 53 y.o. (26-68 y.o.). None of the women had previous pelvic surgery.
These patients received 100U of onaBoNT-A. Significant improvement of many FSFI domains was found. Only desire and pain domains had no significant improvements. The FSFI total score showed a significant improvement (P 0.0008). Table 1 shows the results of the FSFI before and after treatment with onaBoNT-A injection. Clinical efficacy has been documented by voiding diaries, OAB-S scores, and ICIQ-sf scores (table 2). Correlation between UUI episodes and FSFI total score was statistically significant (r= -0.73; p=0.04) while no significant correlation was found between number of micturition and FSFI total score. Correlations between urinary symptoms and the FSFI before and after treatment with onaBoNT-A injection are listed in table 3.
Interpretation of results
We documented a significant correlation between the reduction of episodes of UUI and improvement of FSFI total score. Voiding diaries and questionnaires on urinary symptoms showed a significant improvement after onaBoNT-A injection. The most relevant urinary symptom reducing the sexual function was urge urinary incontinence. The positive effect exerted by onaBoNT-A injection on urinary symptoms may have had a positive impact on the psychological status of the patients. Hence, women with a better control on OAB symptoms may have had a more gratification in the sexual intercourse. A greater self-confidence in sexual intercourses related to a better control of urinary leakages can explain the FSFI domains improvement.
Concluding message
Women underwent OnaBoNT-A detrusor injection to treat wet OAB, showed an improvement in sexual function due to the significant correlation between the improvement of urinary urge incontinence and a better gratification of sexuality.
