RESUMEN
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.

Existing therapies for neurogenic detrusor overactivity (NDO), i.e. oral anticholinergics and botulinum toxin injections, can be associated with serious adverse effects or are not always sufficiently effective. Therefore, there is a need for alternative safe and effective treatment options for NDO. Intravesical oxybutynin has been successfully used for several years as a prescription drug in adults and children with spinal cord injury and spina bifida. In 2019, VESOXX® (FARCO-PHARMA, Cologne, Germany) became the first registered intravesical oxybutynin product in Germany, which is indicated for the suppression of neurogenic detrusor overactivity (NDO) in children from 6 years of age and adults, who are managing bladder emptying by clean intermittent catheterisation (CIC), if they cannot be adequately managed by oral anticholinergic treatment due to lack of efficacy and/or intolerable side effects. Overall, there are limited data regarding therapy with intravesical oxybutynin, with the majority of publications being retrospective case series. To date, there are limited data on the efficacy and safety of the newly approved intravesical oxybutynin therapy (VESOXX®) in NDO patients. This noninterventional case series from daily routine treatment which evaluated the physician reports of 38 patients suggests that intravesical oxybutynin effectively improves maximum detrusor pressure (Pdet max) by decreasing it by 59% from 51.94â¯cm H2O⯱ 26.12 standard deviation (SD) to 21.07â¯cm H2O⯱ 17.32 SD (Pâ¯< 0.001, nâ¯= 34). Maximum bladder pressure (MBC) increased by 34% from 260.45â¯ml⯱ 200.26 SD to 348.45â¯ml⯱ 175.90 SD. Positive or similar effects compared to previous therapies were seen in bladder morphology, number of incontinence episodes, urinary tract infections and adverse drug effects. This case series demonstrates that intravesical oxybutynin is an important addition to current therapies for the treatment of NDO and it is also efficacious in the rare setting of other underlying diseases beyond spinal cord injury or spina bifida. The approved intravesical oxybutynin preparation VESOXX® may be a useful alternative for patients who do not respond to other therapies or suffered side effects.

BACKGROUND: Many factors contribute to developing and conducting a successful multi-data source, non-interventional, post-authorization safety study (NI-PASS) for submission to multiple health authorities. Such studies are often large undertakings; evaluating and sharing lessons learned can provide useful insights to others considering similar studies. OBJECTIVES: We discuss challenges and key methodological and organizational factors that led to the delivery of a successful post-marketing requirement (PMR)/PASS program investigating the risk of cardiovascular and cancer events among users of mirabegron, an oral medication for the treatment of overactive bladder. RESULTS: We provide context and share learnings, including sections on research program collaboration, scientific transparency, organizational approach, mitigation of uncertainty around potential delays, validity of study outcomes, selection of data sources and optimizing patient numbers, choice of comparator groups and enhancing precision of estimates of associations, potential confounding and generalizability of study findings, and interpretation of results. CONCLUSIONS: This large PMR/PASS program was a long-term commitment from all parties and benefited from an effective coordinating center and extensive scientific interactions across research partners, scientific advisory board, study sponsor, and health authorities, and delivered useful learnings related to the design and organization of multi-data source NI-PASS.

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.

INTRODUCTION: Overactive bladder symptoms (OABSs) affect patients' quality of life (QOL) worldwide. This pooled analysis compared the efficacy and safety of mirabegron add-on tamsulosin with those of tamsulosin add-on placebo in OABS treatment. METHODS: PubMed, Embase, MEDLINE, and the Cochrane Controlled Trial Register databases were searched for randomized controlled trials (RCTs) examining the efficacy of mirabegron add-on therapy to tamsulosin in the treatment of OABS. Moreover, references from the selected studies were screened. Review Manager 5.4 was used to analyze data. RESULTS: Four RCTs involving 1,397 patients with OABS were selected. Of the total, 697 patients receiving mirabegron add-on tamsulosin constituted the experimental group, and 700 patients receiving tamsulosin add-on placebo constituted the control group. The efficacy endpoints were as follows: mean number of micturition per day (mean difference [MD] = -0.26, 95% confidence interval [CI] = -0.41 to -0.10, p = 0.0001), urgency episodes per day (MD = -0.67, 95% CI = -1.02 to -0.32, p = 0.0002), urgency urinary incontinence (UUI) episodes per day (MD = -0.42, 95% CI = -0.66 to -0.19, p = 0.0005), mean volume voided/micturition (MD = 10.84, 95% CI = 4.97-16.71, p = 0.0003), total International Prostate Symptom Score (IPSS) (MD = -2.01, 95% CI = -4.02 to -0.01, p = 0.05), and IPSS QOL index (MD = -0.65, 95% CI = -0.94 to -0.35, p < 0.0001). Mirabegron therapy, an add-on therapy to tamsulosin, was effective in treating patients with OABS. Moreover, mirabegron might reduce the total IPSS (MD = -2.01, 95% CI = -4.02 to -0.01, p = 0.05). The safety endpoint, treatment-emergent adverse events (odds ratio = 0.94, 95% CI = 0.78-1.13, p = 0.49), suggested that although mirabegron was well-tolerated, it possibly increased the post-void residual urine volume (MD = 10.28, 95% CI = 1.82-18.75, p = 0.02). CONCLUSION: Combination therapy using mirabegron and tamsulosin may be effective in treating patients with non-neurogenic OABS in terms of UUI episodes, total IPSS, and IPSS QOL index. However, its effectiveness must be verified by analyzing additional factors for OABS through further RCTs.

OBJECTIVE: This study aimed to investigate the efficacy and tolerability of mirabegron and onabotulinum toxin A (BoNT/A) injections for overactive bladders. The treatment we provided was to patients over the age of 65 years who were not satisfied with the results of anticholinergic monotherapy. PATIENTS AND METHODS: This multicenter retrospective observational study was conducted between March 2017 and December 2021. Thirty patients who were unable to take anticholinergics or mirabegron due to side effects received a total of 100-unit intravesical injections of BoNT/A. Furthermore, 30 patients receiving 50 mg of mirabegron daily were compared. Micturition frequency, urgency of urinary incontinence, pad usage, and nocturia were all evaluated for efficacy. Patients' health-related quality of life and subjective satisfaction ratings were assessed before and six months after treatment using an incontinence-quality-of-life questionnaire. We documented all adverse events for all subjects. RESULTS: There was a statistically significant decrease in the frequency, daily pad usage, and incontinence episodes of both groups. The median (interquartile range) voiding frequency after onabotulinum toxin A treatment was lower than that after mirabegron treatment [9.4 (6.83-10.0) vs. 10.5 (8.37-11.67); p = 0.01]. Incontinence episodes showed similar differences [1.3 (1.17-3.67) vs. 2.53 (2.0-5.67); p = 0.05]. There was no significant difference in nocturia or maximum urine flow rate between the groups before and after treatment. CONCLUSIONS: We determined that mirabegron led to lower urinary retention, hematuria, infection and post-void residual urine volume rates than BoNT/A in the older patient population. In addition, mirabegron treatment had comparable incontinence-quality-of-life scores at six months post-treatment.

OBJECTIVES: This study investigates the efficacy and adverse events of beta-3 agonists and antimuscarinic agents for managing overactive bladder syndrome in Sjogren syndrome. METHODS: Sjogren's syndrome patients with an Overactive Bladder Symptom Score (OABSS) >5 were enrolled and were randomly assigned to mirabegron 50 mg/day or solifenacin 5 mg/day. Patients were evaluated on the recruitment day and reassessed at Week 1, 2, 4, and 12. The study's primary endpoint was to have a significant change in OABSS at Week 12. The secondary endpoint was the adverse event and crossover rate. RESULTS: A total of 41 patients were included in the final analysis, with 24 in the mirabegron group and 17 in the solifenacin group. The study's primary outcome was a change of the OABSS at Week 12. We found that both mirabegron and solifenacin significantly reduce patients' OABSS after 12 weeks of treatment. The evolution of the OABSS was -3.08 for mirabegron and -3.71 for solifenacin (p = .56). Six out of 17 patients from the solifenacin group crossed over to the mirabegron arm due to severe dry mouth or constipation, while none from the mirabegron arm crossed over to the solifenacin group. Sjogren's syndrome-related pain was also improved in the mirabegron group (4.96-1.67, p = .008) compared to the solifenacin group (4.39-3.4, p = .49). CONCLUSIONS: Our study showed that mirabegron is equally effective as solifenacin in treating Sjogren's syndrome patients with overactive bladder. Mirabegron is superior to solifenacin in terms of treatment-related adverse events.

OBJECTIVES: This study aimed to assess the efficacy and safety of mirabegron compared with vibegron (both 50 mg once daily) in Japanese female patients with symptoms of overactive bladder (OAB). METHODS: This prospective, 12-week, two-arm, parallel-group, open-label randomized trial (UMIN000038288) was conducted at a single clinic from December 2019 to September 2022. The primary efficacy outcome measure was the change in mean total overactive bladder symptom scores (OABSSs) from baseline to end of treatment (EOT) (Week 12). The secondary efficacy outcome measures were changes in mean International Prostate Symptom Score from baseline to EOT, the ratio of patients who achieved a minimal clinically important change (MCIC) of total OABSS, and individual domains of the King's Health Questionnaire. Safety assessments, such as adverse events (AEs), postvoid residual volume, and patient-reported incidences, were recorded at every visit. RESULTS: There was no statistically significant adjusted mean difference between mirabegron and vibegron in terms of the primary outcome of the mean change from baseline to EOT in the total OABSS. The difference in the percentage of patients in the mirabegron and vibegron groups achieving an MCIC on the total OABSS was not statistically significant but appeared to be clinically important. The incidence of treatment-related AEs was significantly higher for the vibegron group (38.5%) than the mirabegron group (19.1%) (p = .047). CONCLUSIONS: These results showed that both drugs were effective in female OAB patients, with no significant differences in terms of efficacy. However, the safety of vibegron requires further investigation.

Use of α-androgenic receptor blockers remains a mainstay therapeutic approach for the treatment of urological diseases. Silodosin is recommended over other α-blockers for the treatment of lower urinary tract symptoms (LUTS) and benign prostate hyperplasia (BPH), due to its high α1A uroselectivity. Current research data suggest that silodosin is efficacious in the management of various urological diseases. Thus, we herein review the current evidence of silodosin related to its efficacy and tolerability and appraise the available literature that might ultimately aid in management of various urological conditions at routine clinical practice. Literature reveals that silodosin is beneficial in improving nocturia events related to LUTS/BPH. Silodosin exerts effect on relaxing muscles involved in detrusor obstruction, therefore prolonging the need for patients undergoing invasive surgery. Silodosin treatment, either as a monotherapy or combination, significantly improves International Prostate Symptom Score (IPSS) including both storage and voiding symptoms in patients with BPH/LUTS. Patients on other treatment therapies such as phosphodiesterase 5 inhibitors or other α-blockers are well managed with this drug. Steadily, silodosin has proved beneficial in the treatment of other urological disorders such as chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), overactive bladder/acute urinary retention (AUR), premature ejaculation (PE), and prostate cancer post brachytherapy-induced progression. In patients with distal ureteral stones, silodosin treatment is beneficial in decreasing stone expulsion time without affecting stone expulsion rate or analgesic need. Moreover, there were significant improvements in intravaginal ejaculation latency time, quality of life scores, and decrease in PE profile among patients with PE. Silodosin has also demonstrated promising results in increasing the likelihood of successful trial without catheter in patients with AUR and those taking antihypertensive drugs. Reports from Phase II studies have shown promising role of silodosin in the treatment of CP/CPPS as well as facilitating ureteral stone passage. From the robust data in this review, further silodosin treatment strategies in the management of different urological conditions need to be focused on.

INTRODUCTION: Overactive bladder (OAB) and frailty are independently associated with patient burden. However, economic burden and treatment-taking behavior have not been well characterized among frail patients with OAB, which, given the varying safety and tolerability profiles of available treatments, is crucial. OBJECTIVES: To assess costs, health care resource utilization, treatment-taking behavior (persistence and adherence) to OAB medication in older, frail OAB patients. METHODS: This was a retrospective cohort study using international business machines MarketScan Medicare Supplemental claims data. Eligible frail patients (per Claims-based Frailty Index score) initiating mirabegron were 1:2 propensity score matched (based on age, sex, and other characteristics) with those initiating antimuscarinics and were followed up to 1 year. All-cause, per-person, per-month costs, health care encounters, persistence (median days to discontinuation assessed using Kaplan-Meier methods) and adherence (≥80% of proportion of days covered at Day 365) were compared. RESULTS: From 2527 patients with incident mirabegron (21%) or antimuscarinic (79%) dispensations, 516 incident mirabegron users (median age: 82 years, 64% female) were matched to 1032 incident antimuscarinic users (median age: 81 years, 62% female). Median cost was higher in mirabegron group ($1581 vs. $1197 per month); this was primarily driven by medication cost. There was no difference in medical encounters. Adherence (39.1% vs. 33.8%) and persistence (103 vs. 90 days) were higher in mirabegron users. CONCLUSIONS: Among frail older adults with OAB, mirabegron use was associated with higher costs and potential improvements in treatment-taking behaviors, particularly with respect to treatment adherence, versus those initiating antimuscarinics.

Background and Objectives: To determine changes in the blood pressure (BP) and pulse rate (PR) before and after the administration of mirabegron in real-world clinical practice for patients with overactive bladder (OAB). Materials and Methods: This study was conducted in patients newly diagnosed with OAB. Before and 12 weeks after mirabegron treatment, we evaluated the effects on BP and PR. An overall examination was conducted, and the patients were divided into two groups according to their age: a young group (<65 years old) and an old group (≥65 years old). Results: A total of 263 patients were enrolled in this study. In the overall and intragroup comparisons, the systolic BP (SBP) did not change significantly after mirabegron administration. However, an increase in SBP of ≥10 mmHg was observed in 53 (20.2%), 4 (7.4%), and 49 (23.4%) in the entire group, young group, and old group, respectively (p = 0.009). Regarding diastolic BP, a significant decrease after the treatment was detected in entire (71.2 ± 11.4 versus 69.8 ± 10.7 mmHg; p = 0.041) and old patients (71.5 ± 10.6 versus 69.5 ± 10.2 mmHg; p = 0.012). There was no significant change in PR in our study population. Further examination using a propensity match score revealed that age was the risk factor for the increase in SBP after mirabegron administration. Conclusions: Mirabegron does not have any adverse effects on BP and PR. However, since some patients in this study had elevated SBP after administration, we suggest regular BP monitoring during mirabegron treatment.

BACKGROUND/AIM: In clinical practice, constipation is one of the most frequent adverse events caused by drugs for overactive bladder (OAB). The occurrence of constipation greatly deteriorates the patient's quality of life. The aim of the study was to evaluate and compare the effects of three commonly used ß3 agonists and anticholinergic drugs on the defecation status in patients with OAB. PATIENTS AND METHODS: We retrospectively reviewed the defecation status in patients who received mirabegron, solifenacin, or fesoterodine for OAB. We evaluated changes in the (a) urological parameters using the OAB symptom score (OABSS) and (b) defecation status using the Bristol Stool Form Scale (BSFS) and constipation scoring system (CSS) following 12 weeks of drug administration. RESULTS: We analyzed data from 165 patients (mirabegron=56, fesoterodine=52, and solifenacin=57). The solifenacin group showed a significant decrease in BSFS (from 3.2±1.0 at baseline to 2.3±12 post-treatment) and an increase in hardened stools (p<0.001). Elimination worsened as assessed by almost all items, and the total modified CSS scores worsened significantly from 4.8±2.6 points at baseline to 8.O±4.8 points after 12 weeks of solifenacin treatment (p<0.001). The mirabegron group showed no changes in any of the CSS items. In the fesoterodine group, the CSS scores for "completeness" and "assistance" increased significantly after treatment (p<0.001 and p=0.013, respectively). CONCLUSION: All three drugs were effective for OAB. Mirabegron had almost no effect on constipation; fesoterodine, an anticholinergic drug, also had hardly any effect on defecation.

PURPOSE: This cohort study evaluates therapeutic efficacy and adverse events (AEs) of various overactive bladder (OAB) medications for patients with central nervous system (CNS) disorders. METHODS: Patients with OAB and CNS disorders were prospectively enrolled. They were randomly allocated to 3 different treatment subgroups: (1) mirabegron 50 mg once daily (2) solifenacin 5 mg per day, and (3) combined solifenacin 5 mg and mirabegron 50 mg once daily. Efficacy and safety questionnaires and objective parameters were compared among the subgroups, and subgroups between baseline and 3 and 6 months after treatment. AEs, including cognitive dysfunction, were assessed using the Mini-Mental State Examination (MMSE). RESULTS: 102 patients (mean age, 71.8 ± 8.7 years) were enrolled, including 35, 36, and 31 patients received mirabegron monotherapy, solifenacin monotherapy, and combination therapy, respectively. OAB symptoms scores all significantly improved 3 months after treatment in different subgroup. However, PVR increased and VE decreased significantly after treatment in patients receiving solifenacin monotherapy and combination therapy. Dry mouth and constipation were the most common AEs, especially in the solifenacin and combination subgroups. Mild incidence of AEs was noted in patients receiving mirabegron monotherapy. No significant change in MMSE was noted among the subgroups after treatment. CONCLUSION: OAB medication had good therapeutic efficacy in patients who had OAB with CNS disorders, especially in cerebrovascular accident and parkinsonism. No OAB medication or their combination affected cognitive function, whereas minimal AEs were noted with mirabegron. Mirabegron could be recommended as the first choice for managing OAB in these patients.

AIM: To assess real-world treatment profiles, including utilization rate, time to and reasons for discontinuation of combination pharmacotherapy with ß3 -agonists and antimuscarinics for refractory overactive bladder (OAB) through a retrospective chart review. METHODS: We retrospectively reviewed the records of OAB patients who received ß3 -agonists or antimuscarinics at our hospital between 2012 and 2020 and analyzed the clinical course of patients who progressed to combination therapy. Data on age, sex, major complaints, OAB symptom score at the initiation of combination therapy, treatment persistence, and reasons for discontinuation were collected. Treatment persistence was assessed with respect to the median time to discontinuation and persistence rate at 12 months. RESULTS: Of the 2163 patients receiving ß3 -agonists or antimuscarinics, only 84 (3.8%) progressed to combination therapy with both drug classes. At therapy initiation, most (98%) of these patients had moderate to severe OAB symptoms. Median treatment duration and 12-month persistence rate for combination therapy were 595 days and 64.0%, respectively. The reasons for discontinuation were insufficient treatment efficacy followed by adverse effects including voiding impairment in nearly 10% of the patients. None of the baseline parameters was independently associated with persistence in the multivariate analysis. CONCLUSION: While underutilized among OAB patients refractory to monotherapy, combination pharmacotherapy showed a greater persistence rate than published mirabegron or antimuscarinic monotherapy when applied to patients with moderate to severe symptoms. Treatment-emergent voiding impairment is a concern associated with this mode of therapy. A small sample size at a single institution is the limitation of this study.

BACKGROUND: We assessed the efficacy and safety of mirabegron, a ß3-adrenoceptor agonist, in older adults (≥ 80 years old) with overactive bladder (OAB). METHODS: OAB patients aged ≥ 80 years were enrolled in this prospective, single-arm observational study. OAB was diagnosed based on the OAB symptom score (OABSS); i.e., a total score of ≥ 3 points and an urgency score of ≥ 2 points. Patients who received 50 mg mirabegron once daily were evaluated at the baseline and at 4, 8, and 12 weeks. The changes from the baseline in the OABSS, International Prostate Symptom Score (IPSS), OAB questionnaire (OAB-q) score, and Vulnerable Elders Survey (VES-13) score were determined. Adverse events, laboratory tests, 12-lead electrocardiography, the QT interval according to Fridericia's formula (QTcF), uroflowmetry, the post-void residual urine volume (PVR), and the Mini-Mental State Examination (MMSE) score were used to assess safety. RESULTS: Forty-three patients (median age: 84 years, range: 80-96 years) were examined. They had high rates of comorbidities and polypharmacy. Mirabegron significantly improved in total score of the OABSS, including urgency and urge incontinence. The total IPSS, IPSS quality-of-life (QOL) index, and OAB-q scores also significantly improved. Mirabegron improved in the VES-13 score. There were no significant changes in laboratory test values, uroflowmetry findings, PVR, the QTcF, or MMSE score. Two patients (4.7%) withdrew from the study after experiencing adverse events. CONCLUSIONS: Mirabegron was well tolerated and significantly improved in OAB symptoms, and QOL in older patients. Trial registration The present clinical study was approved by University of Yamanashi Institutional Review Board prior to study initiation (ID1447) and was retrospectively registered with the UMIN Clinical Trials Registry (UMIN-CTR), Japan (UMIN000045996) on Nov 6, 2021.

Detrusor underactivity (DU) could be resulted from many different etiologies. Patients with DU might have reduced bladder sensation, low detrusor contractility, and large post-void residual volume. This study analyzed therapeutic outcome of active management for male DU patients, based on clinical and urodynamic characteristics. Male DU patients aged > 18 years old were retrospectively reviewed from the videourodynamic study (VUDS) records in recent 10 years. The patients' demographics, VUDS results, treatment modalities, and treatment outcome were analyzed. The treatment outcomes were compared among patients with different DU subgroups, clinical diagnosis and treatment modalities. Patients with voiding efficiency of > 66.7% were considered having a successful treatment outcome. For comparison, 30 men with normal VUDS finding served as the control arm. Most of the DU patients had reduced bladder sensation. The reduced bladder sensation is closely associated with low detrusor contractility. After active treatment, a successful outcome was achieved in 68.4% of patients after bladder outlet surgery, 59.1% after urethral botulinum toxin A injection, and 57.6% after medical treatment, but only 18.2% after conservative treatment. A successful treatment outcome was achieved in patients with an intact detrusor contractility, either low (69.2%) or normal voiding pressure (81.8%), and in patients with a normal or increased bladder sensation (78.1%). However, patients with detrusor acontractile (41.3%) or absent bladder sensation (17.9%) had less favorable treatment outcome after any kind of urological management. This study revealed that active management can effectively improve voiding efficiency in patients with DU. The normal bladder sensation, presence of adequate detrusor contractility, and bladder outlet narrowing during VUDS provide effective treatment strategy for DU patients. Among all management, BOO surgery provides the best treatment outcome.

PURPOSE: To assess the safety and effectiveness of mirabegron in patients with PD complaining of overactive bladder (OAB). PATIENTS AND METHODS: From January 2017 to November 2020, we performed a prospective randomized, double-blind, placebo-controlled trial that enrolled PD patients with symptoms of OAB. The total duration of the study was 13 weeks, comprising a 1-week screening period and a 12-week treatment period. A total of 110 patients were randomized in one of two groups: treatment group (mirabegron 50 mg) or placebo group. The primary outcomes of our study were the change from baseline in OAB symptom score (OABSS) and the overactive bladder questionnaire short form (OAB-q SF) score. The secondary outcomes were the change from baseline in the mean number of micturitions/24 hours, the mean number of urgency episodes/24 hours, the mean number of urgency incontinence episodes/24 hours and the mean number of nocturia episodes/night, volume voided/micturition (ml) as recorded on a 3-day bladder diary. Safety assessments included adverse events, electrocardiogram, QT corrected for heart rate using Fridericia's correction (QTcF) interval and blood pressure and pulse rate measurements. RESULTS: There was a significant improvement in the primary outcome and secondary outcome measures in the treatment group compared to the placebo group. Adverse events were mild and the same in the two groups. The cardiovascular safety profile was high. This study is limited by its sample size and its short follow-up period. CONCLUSIONS: Mirabegron is a promising drug to control OAB symptoms in patients with PD with an excellent safety profile.

OBJECTIVE: To evaluate the efficacy and safety of vibegron in patients with overactive bladder (OAB) in real-world clinical practice in Japan. METHODS: This multicenter, prospective, non-controlled study consecutively enrolled patients with OAB determined by an OAB symptom score (OABSS) of three points or more and a question 3 (urgency) score of two points or more. A total of 212 patients from 43 institutions were recruited from January 2019 through March 2020. Vibegron, 50 mg, was administrated daily for 8 weeks as first-line monotherapy (first-line group, FL), monotherapy switching from antimuscarinics (post-antimuscarinic group, PA) or mirabegron (post-mirabegron group, PM) and combination therapy with antimuscarinics (add-on group). The OABSS was collected at baseline and every 2 weeks. Adverse events were recorded at every visit. RESULTS: Of the 212 patients registered, 188 (male 76, female 112) were eligible for analysis (124 in the FL group, 27 in PA, 29 in PM, and eight in the add-on group). The add-on group was excluded from further analysis due to its small number. The OABSS (mean ± SD) showed significant improvement in all groups (FL; 8.8 ± 2.5, 3.8 ± 2.8, PM; 9.4 ± 2.2, 4.5 ± 4.0, PM; 8.9 ± 2.5, 4.7 ± 3.3 at 0 and 8 weeks, respectively). The overall incidence of adverse events was 25%. No grade 3 or higher adverse events were observed. CONCLUSIONS: In the real-world clinical setting, vibegron is effective and well-tolerated by OAB patients, including those switching therapy from antimuscarinics and mirabegron.
