Efficacy and Safety of Mirabegron Add-on Therapy After Failure With Solifenacin in Multiple Sclerosis Patients With Overactive Bladder: A Pilot Study.

OBJECTIVES: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative progressive disease of central nervous system that mostly affects young adults. (1) Because of involvement of spinal cord and brain, lower urinary dysfunction symptoms are commonly encountered. MS patients mostly show overactive bladder symptoms like urgency, frequent daytime urination, and urgency incontinence. Among MS patients, antimuscarinic therapy is the first-line treatment with overactive bladder symptoms as well as in general population yet 30% of the patients show insufficient improvement or intolerance to the treatment (2). In our study, our aim is to evaluate the efficacy and safety of mirabegron add-on treatment in MS patients after inadequate response to antimuscarinic monotherapy. METHODS: University of Kyrenia and Dr Burhan Nalbantoglu State hospital's databases were screened for the study. Seventy patients who were residents diagnosed with MS according to McDonald criteria were questioned. Among these patients, a total of 22 of them were included in the study. Inclusion criteria was at least 3 years of MS diagnosis, score of <6 at Expanded Disability Status Scale, and a score of ≥3 at Overactive Bladder Symptom Score Scale. RESULTS: Among selected patients, 10 mg solifenacin treatment was daily started and followed for 4 weeks. Mirabegron add-on treatment was initiated to the 11 patient who had inadequate improvement in overactive bladder symptom score. After mirabegron add-on treatment among 11 patient, there was a sufficient improvement in overactive bladder symptom score ( P < 0.008). CONCLUSIONS: In our study, we have found that antimuscarinic and mirabegron combination causes improved efficacy for overactive bladder in MS population.

Efficacy and safety of solifenacin combined with biofeedback in children with overactive bladder.

BACKGROUND: Overactive bladder is a common chronic urological disorder in children, liable to impact normal social activities, disrupt sleep and even impair self-esteem. We aimed to evaluate the efficacy and safety of solifenacin combined with biofeedback for paediatric overactive bladder. METHOD: Forty-five children with overactive bladder were enrolled and divided into three groups: 15 patients in Group A were treated with solifenacin, 15 cases in Group B with biofeedback, and the other 15 patients in Group C with the combination of solifenacin plus biofeedback. Each group was subdivided into the non-urge incontinence (non-UI) and urge incontinence (UI) groups. The remission rates were compared among the three groups at 2, 4, 8 and 12 weeks from the beginning of treatment. The side effects of solifenacin were recorded and followed up. RESULT: After 2 weeks since initial treatment, the complete response rates were 33.3% (5/15), 20.0% (3/15), and 53.3% (8/15) in the three groups. At 4 weeks, the complete remission rates were 46.7% (7/15), 33.3% (5/15), and 60.0% (9/15) respectively. Moreover, the complete remission rates of the UI groups were higher than the non-UI groups (p < 0.05). At 8 weeks, the complete response rates were 53.3% (8/15), 40.0% (6/15), and 67.7% (10/15). At 12 weeks, the complete response rates were 67.8% (10/15), 60.0% (9/15), and 86.7% (13/15). The complete response rates were higher and urodynamic parameters were improved obviously in group C than the other two groups (p < 0.05) during the follow-ups. The median voiding frequency decreased and median functional bladder capacity increased obviously in Group C after 4 weeks (p < 0.05). Dry mouth was observed in 2 patients (4.4%). 2 patients experienced constipation (4.4%), and neither case was severe. The symptoms of these four patients had relieved by reducing the dose of solifenacin. CONCLUSION: Solifenacin combined with biofeedback had good efficacy and compliance for children experiencing overactive bladder. It took only 2 weeks to achieve the complete response rate over 50%, especially for the improvement of UI symptoms.

A randomized controlled trial evaluating low-intensity shockwave therapy for treatment of persistent storage symptoms following transurethral surgery for benign prostatic obstruction.

BACKGROUND: Low-intensity shockwave therapy (Li-SWT) can improve bladder function through enhancement of angiogenesis and nerve regeneration and suppression of inflammation and overactivity. In this trial, we aimed to evaluate the efficacy of Li-SWT on persistent storage symptoms after transurethral surgery (TUS) for benign prostatic obstruction (BPO). METHODS: Between July 2020 and July 2022, 137 patients with persistent storage symptoms; urgency episodes/24 h ≥ 1 and daytime frequency ≥8, for at least three months after TUS for BPO were randomly allocated to Li-SWT versus sham versus solifenacin 10 mg/day in 3:1:1 ratio. The primary end point was the percent reduction from baseline in overactive bladder symptom score (OABSS) at 3-month follow-up. The changes in 3-day voiding diary parameters, quality of life (QoL) score, peak flow rate and residual urine at 3 and 6-month follow-up were compared. Treatment-related adverse effects were also evaluated. RESULTS: Baseline data were comparable between groups. The percent reduction from baseline in OABSS at 3-month follow-up was significantly higher in Li-SWT compared to sham (-55% versus -11%), and it was comparable between Li-SWT and solifenacin-10 (-55% versus -60%). Li-SWT achieved significant improvement like solifenacin-10 in 3-day voiding diary parameters and QoL score at 3-month follow-up. This improvement remained comparable between Li-SWT and solifenacin-10 at 6-month follow-up. No adverse effects related to Li-SWT were noted apart from tolerable pain during the procedure. Solifenacin-10 was associated with bothersome adverse effects in 73% of the patients with 11.5% discontinuation rate. CONCLUSIONS: Li-SWT ameliorates persistent storage symptoms and promotes QoL after TUS for BPO, with comparable efficacy and better tolerance compared to solifenacin.

Treatment Patterns with Mirabegron and Antimuscarinics for Overactive Bladder: A Prospective, Registry Study in Taiwan and South Korea (FAITH).

INTRODUCTION: This study aimed to assess overactive bladder (OAB) treatment patterns and factors associated with effectiveness and persistence. METHODS: A prospective, longitudinal, observational registry study of adults starting OAB therapy with mirabegron or antimuscarinics was undertaken. Primary endpoints were time from treatment initiation to discontinuation/switching; proportion who discontinued/switched; and reasons for discontinuation/switching. Secondary endpoints included OAB Symptom Score (OABSS), OAB Questionnaire: Short Form, and OAB Bladder Assessment Tool scores; factors associated with effectiveness and persistence; and safety. RESULTS: In total, 556 patients initiating mirabegron and 250 initiating antimuscarinics were enrolled. There was no treatment switch, change, or discontinuation in 68.5% of the mirabegron initiator group and median time to treatment change was not reached. Mean initial treatment duration was 130.8 days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, and patients with mild and moderate OAB had significantly better persistence with mirabegron than those with severe OAB. Urinary tract infection was the most common adverse event with mirabegron. There was no treatment switch, change, or discontinuation in 60.4% of the antimuscarinics initiator group and median time to treatment change was not reached. Solifenacin was the most frequent initial treatment (66.0%). Mean treatment duration was 122.2 days. In multivariable models, baseline OABSS was the only variable significantly associated with change from baseline in OABSS, while patients with OAB medication in the 12 months before enrollment had significantly better persistence with antimuscarinics than those with no previous OAB medication. Dry mouth was the most common adverse event with antimuscarinics. CONCLUSIONS: Mirabegron and solifenacin were commonly prescribed as first-line OAB medications. There was no treatment switch, change, or discontinuation in more than 60% of the mirabegron initiator and antimuscarinics initiator groups. Mean initial treatment duration was 130.8 days and 122.2 days for mirabegron and antimuscarinics, respectively. Graphical Abstract available for this article.

A Comparison of U.S. Individual and Family Plan Medication Coverage for Overactive Bladder.

IMPORTANCE: There is strong evidence for long-term cognitive effects with anticholinergic use. Differences in insurance coverage of anticholinergics and beta-3 agonists hinder individualization of overactive bladder (OAB) treatment. OBJECTIVES: The aims of the study were to assess individual and family health insurance plan coverage for select OAB medications and to compare coverage of preferred medications to those with a greater risk of cognitive dysfunction. STUDY DESIGN: This cross-sectional study analyzed formularies for the top 7 U.S. medical insurers. Coverage tiers were assessed for the following 7 OAB medications: (1) oxybutynin instant-release 5 mg, (2) oxybutynin extended-release 5 mg, (3) solifenacin 5 mg, (4) trospium instant-release 20 mg, (5) trospium extended-release 60 mg, (6) mirabegron 25 mg, and (7) vibegron 75 mg. Coverage was compared between nonpreferred (oxybutynin, solifenacin) and preferred medications (trospium, mirabegron, vibegron). Coverage scores, representing a weighted average based on coverage tier frequency relative to the number of plans investigated for each state or insurer, were generated with a lower coverage score indicating better coverage (range, 0.2-1.0). RESULTS: A total of 2,780 insurance plans from 41 states representing a 47% market share for the individual and family marketplace were evaluated. Oxybutynin IR had the best coverage score across insurers (0.2) while vibegron had the worst (0.92). Preferred medications were more often designated to higher tiers with worse coverage compared with nonpreferred medications (P < 0.001). Less concordance in coverage between insurers was noted for anticholinergics with greater bladder specificity and for extended-release formulations. CONCLUSIONS: Despite risks with anticholinergics, beta-3 agonists were more expensive across all insurers highlighting the need for expanded coverage of preferred medications to avoid cognitive dysfunction when undergoing treatment for OAB.

Predictors of non-persistence in women with overactive bladder syndrome.

Persistence is important for the success in the treatment of women with overactive bladder syndrome (OAB). We aimed to identify the predictors of non-persistence in women with OAB after first-line medical treatment. All consecutive women with OAB (n = 608), who underwent urodynamic studies and received first-line medical treatment (5 mg of solifenacin or 25 mg of mirabegron per day) in a referral medical center, were reviewed. Mirabegron (hazard ratio [HR] = 0.711) was associated with a higher persistence rate, compared to solifenacin. Mirabegron treatment (HR = 0.269) was less likely to switch medication; however, a high Urogenital Distress Inventory score (HR = 1.082) was more likely to switch medication. Furthermore, old age (HR = 1.050, especially for ≥ 75 years) and high voided volume (dL, HR = 1.420, especially for voided volume ≥ 250 ml) were associated with added medication at follow-up. Additionally, women with low parity (HR = 0.653, especially for parity ≤ 3) and a low Incontinence Impact Questionnaire (IIQ-7) score (HR = 0.828, especially for IIQ-7 score ≤ 7) were associated with improvement without medication. In conclusion, mirabegron can be considered as the first frontline treatment to increase the persistence rate and decrease the rate of switched medications, compared to solifenacin. In addition, combination therapy or higher-dose monotherapy could be used as the first front-line treatment for women ≥ 75 years of age or with ≥ 250 ml of voided volume.

HYPERACTIVE BLADDER SYNDROME SECONDARY TO BAROTRAUMA AND CHRONIC STRESS.

OBJECTIVE: The aim: To improve the results of treatment of hyperactive bladder syndrome in men of working age on the background of barotrauma and stress, as a consequence of combat trauma. PATIENTS AND METHODS: Materials and methods: An analysis of the questionnaire and the results of the clinical examination of 32 patients, injured servicemen and people who were injured in combat zones was carried out. The drug solifenacin succinate was used in the treatment complex, which is a specific antagonist of M3 subtype cholinergic receptors. Its influence allows you to achieve relaxation of the bladder detrusor and reduce the contractility of hyperactive bladder. RESULTS: Results: The main criterion for the effectiveness of the treatment was a decrease in the number of urgent cases, the frequency of urination and manifestations of nocturia by 50% or more, which was considered a positive effect. At the same time, the positive effect was differentiated as follows : an improvement of these parameters by 75% or more from the initial value which is a good result; reduction of symptoms in the range of 50-75% is satisfactory; less than 50% is an unsatisfactory result. A positive effect from the treatment after 8 weeks was observed in 88% of patients, of which 52% had a good result and 36% had a satisfactory result. CONCLUSION: Conclusions: The proposed complex of treatment of hyperactive bladder syndrome as a result of combat trauma against the background of barotrauma with neurological consequences and chronic stress allows to achieve a pronounced clinical effect in the vast majority of male patients of working age. And the diagnostic complex allows you to emphasize aspects of clinical vigilance, both for doctors of a specialized branch and of doctors of a general direction.

A randomized controlled trial study on effectiveness between tadalafil versus combination mirabegron and solifenacin on treatment of ureteral stent-related symptoms.

Introduction: ureteral stents have common complications like ureteral stent-related symptoms (SRSs). This study investigated the effectiveness of tadalafil compared to mirabegron and solifenacin combination therapy in patients with ureteral SRSs after double-J (DJ) stent insertion. Methods: this double-blind, randomized clinical trial used consecutive random sampling in participants with SRSs after double-J stent insertion. The study was conducted at four different hospitals in Makassar, Indonesia, from July to December 2020. Ureteral stent-related morbidity indices which analyzed include urinary symptoms, pain, general health, quality of work, and sex scores. All of the indices were measured by ureteral symptom score questionnaire for the first, second, third, and fourth weeks after drug consumption, either tadalafil 10 mg/day (group A, n=25) and a combination of mirabegron 25 mg/day and solifenacin 5 mg/day (group B, n=28). Results: before the treatment procedure, the groups were comparable in age, gender, body mass index, DJ stent procedures, type, and indication. In general, the score in all parameters declined over the follow-up time for both groups. Group A had a lower urinary symptom score than group B at week III and week IV (all p-value < 0.001). In addition, group A had a lower pain score, general condition, work activity, and other complaints than group B at week II, week III, and week IV (all p-value <0.001). The sexual activity score is comparable between the group, except in week I. Conclusion: according to our results, we suggest tadalafil to minimize stent-related urinary symptoms and improve general health in patients with double J stent.

Ureteral Stent-Related Symptoms and Pharmacotherapy: A Brief Narrative Review.

The purpose of this article is to review the effects of different types of pharmacotherapy on symptoms that affect the quality of a patient's life after stent insertion. A thorough Medline/PubMed nonsystematic review was conducted from 1987 to January 2023, using the terms: "pigtail" OR "ureteral stents" AND "lower urinary tracts symptoms" OR "LUTS" AND "pharmacotherapy" OR "drugs". Relevant studies conducted in humans and reported in English language were included. The available reviews and articles associating the use of drugs with stent-related symptoms (SRS) provide conflicting results. Most of them show a clear benefit of alpha blockers, particularly alfuzosin, on treating urinary SRS, and hence there is a strong recommendation for the use of alpha blockers for the treatment of SRS in the guidelines of the European Association of Urology. Anticholinergics and mirabegron have shown a significant benefit in dealing with irritative bladder symptoms. In contrast, the findings for combination therapies are contradictory, with some studies showing that combination therapy is no superior to monotherapy with regards to most of the subsets of the Ureteral Stent Symptom Questionnaire (USSQ), whereas others present a clear benefit of combination therapies, specifically silodosin and solifenacin, in treating stent-associated lower urinary tract symptoms (LUTS), in comparison with any other type of monotherapy or combination therapy. Many studies suggest that some categories of pharmacotherapy, such as alpha blockers, can alleviate SRS. However, there is conflicting evidence concerning most other types of medical treatment. Randomized trials with the largest number of patients are needed to investigate the effectiveness of novel approaches on SRS.

Comparison Of Solifenacin And Mirabegron For The Treatment Of Overactive Bladder.

BACKGROUND: Overactive bladder is mostly treated with a combination of behavioural interventions and commonly prescribed anti-muscarinic medication therapy, including solifenacin, which has considerable side effects and lowers the quality of life. Mirabegron relaxes the detrusor muscle and is a recently approved drug for the treatment of OAB. This study examined the effectiveness and safety of two medications, solifenacin and mirabegron. METHODS: This study was a comparative cross-sectional study conducted at Sami Medical Center, Abbottabad for a period of 6 months from August 2022 to January 2023. Female patients of aged ≥18 years with symptoms of OAB were enrolled. RESULTS: Current study showed that the average age of patients was 37.47±12.48 years in Group S and 39.93±7.93 in Group M. The population consists of 60 (100%) females. After 4 weeks of follow up dizziness, dry mouth, constipation hypertension and blurred vision were found insignificant between both groups with p-values of 0.312, 0.161, 0.076, 0.076, and 0.313 respectively. OABSS score improved significantly and after therapy 4.20±1.32 in Group S and 3.43±1.13 in Group M. There was no significant difference in frequency of treatment withdrawal p-value 0.150. CONCLUSIONS: When it comes to relieving symptoms of OAB, both solifenacin and mirabegron are effective. The OABSS improved with both drugs; however, mirabegron was associated with fewer treatment-related adverse events. We advocate using mirabegron as the first-line treatment. Solifenacin can be utilized if patients are no longer getting the desired effects from Mirabegron.

[Assessment of prescribing practices in overactive bladder pharmacotherapy across different specialties of India: a prescription trend analysis].

PURPOSE: To assess the prescribing practices for overactive bladder (OAB) pharmacotherapy based on the prescription trend analysis across different specialties of India. METHOD: s: IQVIA (Quintiles and IMS Health) secondary sales audit (SSA), as well as a prescription audit for antimuscarinics and beta-3 adrenoceptor agonists (mirabegron) from 2014 to 2021, were analyzed. The data includes SSA data of various antimuscarinics like solifenacin, oxybutynin, tolterodine, darifenacin, trospium and mirabegron change in the prescription trend of antimuscarinics and mirabegron across different specialties; prescribers overlap analysis for solifenacin and mirabegron among Indian urologists were also analyzed. RESULTS: Urologists prescription rates of OAB drugs were 65% in 2016 and 54% in 2021. The rate of OAB medication prescription by non-urologist was highest from the surgeon (11%), followed by gynecologists (9%) and consultant physicians (8%) in 2021. In addition, among OAB medication prescription rates for antimuscarinics were 100% in 2016 and 58% in 2021 whereas for mirabegron, it was 0% in 2016 and 42% in 2021. Solifenacin was most frequently prescribed anticholinergics, followed by oxybutynin, tolterodine, darifenacin, and trospium. The proportion of prescribers of OAB medication among urologists was 38% in 2016 and 33% in 2021. Exclusive prescribers of solifenacin were 748 in 2018 and 739 in 2021 at the urologist, whereas for mirabegron, it was 961 in 2018 and 934 in 2021. The compound annual growth rate for prescription of the last 6 years (from 2016-2021) for solifenacin and mirabegron was -3% and 8% respectively. CONCLUSIONS: Urology remained a top prescribing specialty for OAB drugs, although prescription share increased at surgeon and consultant physician. OAB medicines prescriptions by urologists are shifting from leading antimuscarinic solifenacin to beta-agonist mirabegron. Data from this study will ultimately lead to the OAB medication preference by the specialist that could lead to more advanced OAB management.

Comparative Analysis of Solifenacin Plus Desmopressin Versus Desmopressin Alone in the Treatment of Primary Mono Symptomatic Nocturnal Enuresis.

OBJECTIVES: To compare the efficacy and tolerability of Solifenacin plus Desmopressin and Desmopressin alone in the treatment of primary monosymptomatic nocturnal enuresis (PMNE). METHODS: A total of 88 children, 5-14 years old, diagnosed with PMNE were enrolled in this randomized control trial (RCT) from June 2017 to June 2020. After informed written consent patients were randomized to one of the two therapeutic groups. Group 1 received one puff of desmopressin nasal spray 1 h before bedtime every night. Group 2 received one pill of solifenacin 5 mg plus one puff of desmopressin nasal spray 1 h before bedtime every night. All patients were evaluated after three months for their response to treatment and drug side effects. RESULTS: The mean age in desmopressin alone group and solifenacin plus desmopressin group was 8.1 ± 2.2 (5-14) and 7.9 ± 2.2 (5-14) years respectively (p-value >0.05). In group 2, 37/44 (84.09%) patients achieved complete response after three months of treatment in comparison to group 1 in which 27/44 (61.36%) patients showed complete response (p-value <0.05). In group 1, 8/44 (18.18%) patients developed treatment related side effects whereas in group 2, 12/44 (27.27%) patients developed side effects (p-value >0.05). No case of discontinuation of treatment due to side effects was observed in any of the two groups. The recurrence rate was also significantly lower in group 2 in comparison to group 1 (8.1% vs 33.3%, p-value <0.05). CONCLUSION: Our study demonstrated that the combination of Solifenacin plus Desmopressin is more effective than desmopressin monotherapy in the treatment of PMNE with an acceptable tolerability profile. LEVEL OF EVIDENCE: Level I.

TOT in combination with solifenacin or intravaginal prasterone in postmenopausal women with mixed urinary incontinence: A retrospective analysis in 112 patients.

OBJECTIVES: The aim of this study was to compare the efficacy of the transobturator tape (TOT) procedure combined with solifenacin (TOT-S) or prasterone (TOT-P) in postmenopausal women affected by mixed urinary incontinence (MUI) with a predominant stress urinary incontinence component. METHODS: This is a retrospective analysis including 112 patients: 60 patients of the TOT-S group and 52 patients of the TOT-P group. Physical examination, 3-day voiding diary, urodynamic tests, and Vaginal Health Index (VHI) were compared at the beginning of the analysis and after 12 weeks of follow-up (FU). Specific questionnaires were administered to indagate the impact on women's quality of life and sexual function. RESULTS: After 12 weeks of FU, the detrusor's peak flow pressure was significantly different between the two groups (p = .02). Detrusor overactivity decreased only in the TOT-P group (p = .05). At the end of FU, 58 patients (96.7%) of the TOT-S group and 50 patients (96.2%) of the TOT-P group were dry at the stress test. A significative group difference was observed in urge urinary incontinence (24 h) (p = .01) but not in the mean number of voids (24 h) and urgent micturition events (24 h). VHI improved only in the TOT-P group (12.57 ± 3.80 vs. 19.75 ± 4.13, p < .0001). The questionnaires and Patient Global Index of Improvement (PGI-I) scores showed comparable improvements, while the Female Sexual Function Index improved especially in the TOT-P group (p < .001). CONCLUSIONS: In postmenopausal women with MUI, TOT-P demonstrated the same effectiveness as TOT-S in reducing urinary symptoms. In addition, TOT-P increased VHI and sexual function scores compared with TOT-S.

Patient Perception of Bladder Condition after Treatment with Solifenacin and Tolterodine in Overactive Bladder Patients.

BACKGROUND: Solefinacin and Tolterodine are new generation antimuscarinics claimed to have bladder specific action and less adverse effect like dry mouth. The objective of the study was to compare the improvement in urinary symptoms among patients using solefinacin and tolterodine with overactive bladder symptoms. METHODS: A hospital based cross-sectional comparative study was done for one year duration. All patients with overactive bladder symptoms were included and in every alternate patient's solefinacin and tolterodine were given after taking note of baseline OAB symptoms, PPBC score and UPS score. Participants were followed up after one month and noted improvement in endpoint OAB symptoms. Comparison of baseline to end-point symptoms changes among each group of participants were analyzed for statistical significance. RESULTS: Among 101 participants included in the study, 49 participants were in solefinacin group and 52 participants were in tolterodine group. The end-point comparison of urgency symptoms were improved by 20.1±6.76 (mean ± SD) units in solefinacin group and by 17.0 ± 9.18 units in tolterodine group. Urgency perception score improved to 2.1±0.66 for patients under solefinacin and 2±0.73 for tolterodine. Patient perception of bladder condition (PPBC) showed improvement in solefinacin group by 3.2±1.26 units and in tolteradine by 2.8±1.54 units (p = 0.165). Comparing the patient's perception of treatment outcome, massive improvement was reported by 81.6% of those receiving Solefinacinand 65.4% receiving tolterodine, though not statistically significant ( p = 0.131). CONCLUSIONS: Solefinacin and Tolterodine showed improvement in urinary symptoms, UPS and PPBC. Both showed comparable efficacy without significant superiority over one another.

Urobiome changes differ based on OAB treatment in adult females.

INTRODUCTION AND HYPOTHESIS: Representatives of two classes of oral medication are often used to treat urgency urinary incontinence (UUI): solifenacin, an M3-receptor-selective antimuscarinic, and mirabegron, a beta-3 agonist. Two previous asynchronous drug-specific studies suggested different interactions between these medications and the urobiome despite identical methodologies, including recruitment, sample procurement, medication dose escalation strategy, determination of 12-week responders versus nonresponders, and data collection. This analysis compares data from these two studies using a uniform analytic approach. METHODS: Urine was collected aseptically via transurethral catheter from consenting participants for subsequent processing by the Expanded Quantitative Urine Culture (EQUC) protocol in two cohorts (n=50 and n=47) that were demographically similar. Species accumulation curves were generated to compare the total number of unique species detected. Indices that measure richness, evenness, and/or abundance were used to compare alpha (within sample) diversity. The Bray-Curtis Dissimilarity Index was used to determine between sample (beta) diversity. RESULTS: The majority of the 40 species detected in the pre-treatment urobiomes were detected in both cohorts. Both pre-treatment urobiomes were substantially similar in species richness, evenness, and diversity. Differences in pre-treatment urobiomes were associated with treatment response for solifenacin-treated participants only. In contrast, the pre-treatment urobiomes of mirabegron-treated participants were not associated with treatment response. Changes in the post-treatment urobiomes were detected in both cohorts with an increase in richness for both solifenacin (5-mg dose only) and mirabegron. CONCLUSIONS: Pre-treatment urobiome characteristics were associated with treatment response in participants treated with solifenacin, but not mirabegron. Differences exist in urobiome response after treatment with two medications that have known differences in mechanism of action.

Efficacy of frankincense-based herbal product in urinary incontinence: A randomized, double-blind, placebo- and active-controlled clinical trial.

Urinary incontinence is a silent epidemic that has a serious impact on a person's quality of life (QOL). This study aimed to evaluate the efficacy of frankincense-based herbal product (FHP) in urinary incontinence compared with placebo and solifenacin. In this randomized, double-blind clinical trial, 120 postmenopausal women with mixed urinary incontinence were randomized to one of the three groups of FHP, placebo, and standard treatment (solifenacin). Frequency, amount of leakage, and score of urinary incontinence as well as the QOL were measured at the end of the second and fourth weeks and 2 weeks after the interruption of the treatment. The ICIQ-UI SF and I-QOL questionnaires were used for the measurements. Mean frequency of urinary incontinence and amount of leakage significantly decreased in the FHP and solifenacin groups in the fourth week compared to the placebo group. In addition, 2 weeks after treatment completion, the effects of the FHP were significant compared to the solifenacin group. Due to the effect of FHP on improving the QOL and also the prolonged effect of this drug, the use of FHP in urinary incontinence, as a complementary treatment could be suggested.

Cold stress-induced bladder overactivity in type 2 diabetic mellitus rats is mitigated by the combination of a M3 -muscarinic antagonist and a ß3 -adrenergic agonist.

OBJECTIVES: Goto-Kakizaki (GK) rats with type 2 diabetes mellitus respond to low temperature (LT) environments with bladder overactivity, including increased voiding frequency and decreased voiding interval and micturition volume. We determined if bladder overactivity could be inhibited by treatment with the combination of a M3 -muscarinic receptor antagonist and a ß3 -adrenergic receptor agonist. METHODS: Ten-week-old female GK rats were fed a high-fat diet for 4 weeks. Cystometric investigations were conducted at room temperature (RT, 27 ± 2°C). The rats were then intraperitoneally administered the vehicle, the M3 -muscarinic receptor antagonist solifenacin, the ß3 -adrenergic agonist mirabegron, or a combination of solifenacin and mirabegron. Ten minutes after the administrations, the rats were transferred to the LT environment (4 ± 2°C), where the cystometric measurements were continued. The expressions of both M3 -muscarinic and ß3 -adrenergic receptors were investigated. RESULTS: After transfer from RT to LT, both voiding interval and bladder capacity of the vehicle-, solifenacin-, or mirabegron-treated rats were significantly decreased. However, the combination of solifenacin and mirabegron significantly mitigated the bladder overactivity. While both M3 -muscarinic and ß3 -adrenergic receptors were detected, the expression of M3 -muscarinic receptor mRNA was significantly higher than that of ß3 -adrenergic receptor mRNA. CONCLUSIONS: The cold stress-induced bladder overactivity was not improved by either the M3 -muscarinic receptor antagonist or the ß3 -adrenergic receptor agonist alone. However, the combined treatment mitigated the cold stress responses. Combined therapy with M3 -muscarinic antagonists and ß3 -adrenergic agonists could reduce side effects and improve the quality of life for diabetic patients with bladder overactivity.

Prospective, Randomized, Multicenter Trial of Peroneal Electrical Transcutaneous Neuromodulation vs Solifenacin in Treatment-naïve Patients With Overactive Bladder.

PURPOSE: We investigated the safety and efficacy of peroneal electrical transcutaneous neuromodulation using the URIS neuromodulation system in a home-based setting in comparison with standard treatment using solifenacin in treatment-naïve female patients with overactive bladder. MATERIALS AND METHODS: A total of 120 patients were screened, of whom 77 were randomized in a 2:1 ratio to 12 weeks of treatment with daily peroneal electrical transcutaneous neuromodulation or solifenacin 5 mg. The primary endpoint was safety; efficacy assessments included proportion of responders, defined as subjects with ≥50% reduction in bladder diary-derived variables; Overactive Bladder-Validated 8-question Screener, and European Quality of Life-5 Dimensions questionnaire; and treatment satisfaction after 12 weeks of therapy. RESULTS: Seventy-one out of 77 randomized patients completed the study. In the peroneal electrical transcutaneous neuromodulation group 6/51 (12%) patients reported a treatment-related adverse event vs 12/25 (48%) in the solifenacin group (P < .001). No clinically significant changes were observed in any other safety endpoint. The proportions of responders in the peroneal electrical transcutaneous neuromodulation group vs the solifenacin group were 87% vs 74% with respect to Patient Perception of Intensity of Urgency Scale grade 3 urgency episodes, 87% vs 75% with respect to grade 3+4 urgency episodes, and 90% vs 94% with respect to urgency incontinence episodes. In post hoc analyses we observed significant improvement over time in multiple efficacy variables in both treatment arms. CONCLUSIONS: Peroneal electrical transcutaneous neuromodulation is a safe and effective method for overactive bladder treatment associated with a significantly lower incidence of treatment-related adverse events compared to solifenacin and a considerably better benefit-risk profile.

Study of mirabegron and solifenacin in the improvement of catheter-related bladder discomfort in patients undergoing transurethral resection: A case-control study.

BACKGROUND: The goal of this study was to see if using mirabegron, solifenacin, or placebo may help patients with transurethral resection avoid catheter-related bladder discomfort (CRBD). METHODS: Patients who underwent transurethral surgery and were given a catheter for 3 days after surgery were chosen for this study. The enrolled patients were separated into 3 groups: mirabegron (M), solifenacin (S), and a blank control group (C). All patients had their overactive bladder symptoms score (OABSS) and blood pressure checked before surgery. The CRBD, blood pressure, and heart rate were measured at 6, 24, 48, and 72 hours after surgery. The OABSS and side effects were documented on the 7th day. RESULTS: The 104 patients in this trial were randomized into 3 groups at random: M, S, and C. The ultimate follow-up was completed by 99 patients, including 33 in group M, 33 in group S, and 33 in group C. The OABSS, CRBD, and blood pressure in groups M and S were similar before and after surgery (P > .05). Groups M and S performed much better on the OABSS and CRBD than group C (P < .05). There were no significant differences in blood pressure between the 3 groups (P > .05). There were no significant differences in the occurrences of new onset dry mouth (P = .84) or constipation (P = .64) among the 3 groups. CONCLUSION: Mirabegron is comparable to solifenacin as an alternative for the prevention of CRBD, making it a viable option for CRBD prevention.
