The effect of extended release tolterodine used for overactive bladder treatment on female sexual function

The impact of pharmacotherapy on sexual function in female patients being treated for idiopathic overactive bladder: a systematic review

BACKGROUND

Overactive bladder (OAB) is a condition defined by urgency with or without incontinence which disproportionately affects female patients and has a negative impact on sexual enjoyment and avoidance behaviour. Pharmacotherapy can be considered one of the main options for treating OAB. This research set out to determine the impact of pharmacotherapy on sexual function in females with OAB.

METHODS

This research used the robust methodology of a systematic review. The clinical question was formulated using the PICO (population, intervention, control, and outcomes) format to include females being treated with pharmacotherapy (anticholinergics or beta-3 adrenergic agonists) for idiopathic OAB with the use of a validated questionnaire assessing self-reported sexual function at baseline and post-treatment. The review incorporated the MEDLINE, PubMed and EMBASE databases. The AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews) appraisal tool was used to guide the review process. Two reviewers worked independently in screening abstracts, deciding on the inclusion of full-texts, data extraction and risk of bias assessment.

RESULTS

In female patients with OAB, pharmacotherapy does seem to offer at least partial improvement in self-reported sexual function outcomes after 12 weeks of therapy. Still, the value of this finding is limited by an overall poor quality of evidence. Patients with a higher degree of bother at baseline stand to benefit the most from treatment when an improvement within this health-related quality of life domain is sought.

CONCLUSION

This research should form the basis for a well-conducted randomized controlled study to accurately assess sexual function improvements in females being treated with pharmacotherapy for OAB.

The effects of mirabegron used for overactive bladder treatment on female sexual function

Background/Aim: Overactive bladder (OAB) is a common condition, especially in middle-aged women and can frequently have negative effects on female sexual function (FSD). The aim of the study was to assess the impact of mirabegron on female sexual dysfunction in women affected by OAB. Methods: In this cross-sectional study, 42 women with OAB and FSD were retrospectively enrolled. Patients were evaluated based on a detailed history, physical examination, uroflowmetry and residual urine measurements, 3-day voiding diary, visual analog scale (VAS), and Female Sexual Function Index (FSFI) questionnaire before and 12 weeks after treatment with mirabegron (50 mg/day). Results: At the 12-week follow-up, OAB symptoms improved significantly in all patients. The mean (standard deviation [SD]) FSFI total score significantly improved in 34/42 patients (80.9%) from 16.8 (1.3) to 26.9 (1.6); P<0.001. Mean (SD) scores significantly increased in domains of desire (from 2.1 [0.6] to 4.8 [0.2]), arousal (from 2.6 [0.3] to 4.3 [0.5]), lubrication (from 3.1 [0.6] to 4,1 [0.2]), orgasm (from 3.1 [0.2] to 4.3 [0.1]), and satisfaction (from 2.8 [0.4] to 4.1 [0.5]) after 12 weeks of treatment with mirabegron. Also, mean VAS scores significantly improved from 4.4 (1.4) to 8.8 (1.1); P<0.001. Conclusion: Treatment of OAB with mirabegron yields positive effects on sexual function of OAB patients.

Quality of Life, Psychological Wellbeing, and Sexuality in Women with Urinary Incontinence—Where Are We Now: A Narrative Review

Urinary incontinence (UI) is a very common condition, negatively affecting social, occupational, domestic, and psychophysical wellbeing. In particular, a peculiar and detrimental effect of UI has been described concerning sexual function. However, the impact of UI on quality of life is not fully understood yet, and further investigation into this issue is warranted. With this narrative review, we aimed to report the current evidence from recent literature regarding the quality of life and psychological wellbeing in patients with urinary incontinence, with a special focus on sexual function and its evolution after UI treatment. There is strong evidence that urinary incontinence—in its different forms, including stress urinary incontinence, urge urinary incontinence, mixed urinary incontinence, and coital urinary incontinence—negatively affects female sexual function. Treatments aimed to cure urinary incontinence—including pelvic floor muscles training, medications, and surgery—seem to improve quality of life by recovering, at least in part, sexual function. In conclusion, there is a substantial association between involuntary urinary loss and sex life quality. However, few studies are available and more evidence is needed before consistent conclusions can be made.

Impact of intravesical onabotulinumtoxinA (Botox) on sexual function in patients with overactive bladder syndrome: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

The association between overactive bladder (OAB) syndrome and sexual dysfunction is well documented. Intra-detrusor onabotulinumtoxinA (Botox) has proven to be effective treatment for OAB syndrome. Our aim was to examine the impact of intravesical Botox injection on sexual function in patients with OAB, by systematically reviewing the literature.

METHODS

We reviewed the literature for studies that reported a change in sexual function after Botox treatment in patients suffering from OAB. This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement using pre-agreed keywords, from database inception to December 2020. Statistical analyses were performed using Review Manager (RevMan; v.5.4).

RESULTS

Initial results yielded 455 citations. Seven articles met our inclusion criteria. One article was double-reported, leaving 6 studies in the systematic review. Three observational before-and-after studies used the Female Sexual Function Index (FSFI) with sufficient information, and therefore were included in our meta-analysis. The pooled number of participants in all studies was 119 patients. In the meta-analysis, there was significant improvement in the following domains of the FSFI after Botox injection; desire (mean difference (MD) -0.51, p = 0.02), arousal (MD -0.86, p = 0.02), lubrication (MD -0.57, p = 0.03), orgasm (MD -0.65, p = 0.0003) and satisfaction (MD -0.46, p = 0.05). Pain was the only domain that did not show improvement (MD -0.07, p = 0.79). The total FSFI score was reported in 88 patients (two studies) showing significant improvement (MD -0.77, p = 0.006).

CONCLUSIONS

We report a systematic review of the effect of Botox treatment on sexual function in patients with OAB. Although studies are small, the results indicate a positive effect in patients with OAB.

Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition)

The present article is an abridged English translation of the Japanese Clinical Guidelines for Female Lower Urinary Tract Symptoms (second edition), published in September 2019. These guidelines consist of a total of 212 pages and are unique worldwide in that they cover female lower urinary tract symptoms other than urinary incontinence. They contain two algorithms for "primary treatment" and "specialized treatment," respectively. These guidelines, consisting of six chapters, address a total of 26 clinical questions including: (i) treatment algorithms; (ii) what are female lower urinary tract symptoms?; (iii) epidemiology and quality of life; (iv) pathology and illness; (v) diagnosis; and (vi) treatment. When the patient's symptoms mainly involve voiding and post-micturition symptoms, specialized treatment should be considered. In the event of voiding symptoms concurrent with storage symptoms, residual urine should be measured; if the residual urine volume is <100 mL, then diagnosis and treatment for storage symptoms is prioritized, and if the volume is ≥100 mL, then specialized treatment should be considered. When storage symptoms are the primary condition, then the patient is subject to the primary treatment algorithm. Specialized treatment for refractory overactive bladder includes botulinum toxin injection and sacral nerve stimulation. For stress urinary incontinence, surgical treatment is indicated, such as urethral slings. The two causes of voiding symptoms and post-micturition symptoms are lower urinary tract obstruction and detrusor underactivity (underactive bladder). Mechanical lower urinary tract obstruction, such as pelvic organ prolapse, is expected to improve with surgery.

Comparison of vascularization and overall perfusion of the bladder wall between women with and without overactive bladder syndrome

The pathophysiology of female overactive bleeder syndrome (OAB) remains undetermined. Our aim is to elucidate the role of vacularization and overall perfusion of the bladder wall in women with OAB. Between 2010 and 2016, women with OAB and the asymptomatic controls were enrolled. Women with OAB were treated with tolterodine. Women with OAB (n = 40) had higher vascularization index (0.40 ± 0.57 versus 0.17 ± 0.22, p = 0.003), vascularization-flow index (0.15 ± 0.28 versus 0.05 ± 0.08, p = 0.003) and thicker trigone (0.56 ± 0.13 cm versus 0.47 ± 0.11 cm, p = 0.004), compared with the controls (n = 34). The following optimum cut-off values to predict OAB were determined: (1) vascularization index (%) ≥ 0.16, (2) vascularization-flow index ≥ 0.032, and (3) trigone bladder wall thickness ≥ 0.47 cm with an area under the curve of 0.71, 0.71 and 0.70, respectively. Correlation analysis showed that a significant correlation between urgency and vascularization index/vascularization-flow index (Spearman’s rho = 0.34 and 0.35, respectively, all p < 0.01). However, after 12 weeks of tolterodine treatment, the vascularization index, flow index and vascularization-flow index did not differ between baseline and after treatment. In conclusion, women with OAB have higher vascularization and overall perfusion of the bladder wall, compared women without OAB. However, vascularization and overall perfusion did not change after antimuscarinic treatment.

Effect of mirabegron on erectile function in sexually active men with bothersome overactive bladder symptoms

BACKGROUND

To evaluate the change of erectile function (EF) in sexually active male overactive bladder (OAB) patients treated with Mirabegron. Mirabegron, a selective β3 adrenoceptor agonist, approved for the treatment of OAB, has been reported to relax human and rat corpus cavernosum and might have beneficial effect on EF.

METHODS

A total of 128 consecutive men with lower urinary tract symptoms attended urology outpatient clinic were evaluated for OAB and EF. Thirty-four sexually active OAB patients were prospectively enrolled in this study and received mirabegron 50 mg oral once a day. The evaluation of EF and OAB was based on a self-administered questionnaire containing International Index of Erectile Function (IIEF-5) and OAB symptom score (OABSS), respectively. Men with an OABSS urgency score of ≥2 and sum score of ≥3 were considered to have OAB. The therapeutic outcomes were assessed at baseline, 4, and 12 weeks.

RESULTS

Mirabegron usage was associated with a statistically significant improvement of OAB symptoms (OABSS 32.1% decrease) at 4-week follow-up and the therapeutic effects were maintained at 12-week follow-up. Mirabegron usage did not improve EF (IIEF-5 4.9% decrease at 4-week; p = 0.106, and 9.1% decrease at 12-week follow-up; p = 0.077). However, the IIEF-5 was significantly decreased in the higher baseline IIEF-5 (≥17) group (11.7% decrease; p = 0.044), noncoronary artery disease (13.2%; p = 0.007), or non-DM group (13.9% decrease; p = 0.021) at 12-week follow-up.

CONCLUSION

This preliminary study demonstrates that mirabegron treatment of men with OAB improved OAB symptoms, but has no beneficial effect on EF.

Overactive Bladder Syndrome Treatments and Their Effect on Female Sexual Function: A Review

Introduction

Overactive bladder (OAB), the most common subtype of urinary incontinence, has a heavy price on quality of life, especially on sexual life. Unfortunately, most women rarely voice the worsening of sexual function, especially those who already suffer from OAB symptoms. It has been demonstrated that patients who suffer from OAB score lower on Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire and Female Sexual Function Index scores, meaning that their sexual function is debilitated. Therapies for OAB begin with traditional pelvic floor physiotherapy, advance to anticholinergic drugs, and become more invasive with intravesical injections of onabotulinumtoxinA (commonly known as Botox). Last, for patients resistant to conservative therapies, sacral neuromodulation is the treatment of choice.

Methods

This article reviews the current literature that sheds light on the above 4 treatments and their effect on sexual function. This topic is of great importance because of the under-reporting of sexual dysfunction in women who suffer from OAB, in hopes of raising awareness of sexual function for clinicians treating patients with OAB.

Results

This review found that the aforementioned 4 treatments for OAB (physiotherapy, anticholinergic drugs, intravesical injections of onabotulinumtoxinA, and sacral neuromodulation) do not have a detrimental affect on sexual function. On the contrary, the little data that do exist show that sexual function increases after these therapies are completed in women with OAB.

Conclusion

This review concludes with a positive outlook: physicians are helping women with OAB syndrome to improve their sexual function. However, not enough data exist, partially due to under-reporting of diminished sexual function.

The impact of Mirabegron on sexual function in women with idiopathic overactive bladder

Background

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.

Methods

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).

Results

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).

Conclusions

Mirabegron not only is able to control urinary symptoms in women with OAB, but also induces a significant improvement in their sexual life.
