Non-pharmacological and drug treatment of autonomic dysfunction in multiple system atrophy: current status and future directions. J Neurol 2023; 270:5251-5273. [PMID: 37477834 DOI: 10.1007/s00415-023-11876-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 07/11/2023] [Accepted: 07/11/2023] [Indexed: 07/22/2023]
Abstract
Multiple system atrophy (MSA) is a sporadic, fatal, and rapidly progressive neurodegenerative disease of unknown etiology that is clinically characterized by autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs in any combination. Early onset and extensive autonomic dysfunction, including cardiovascular dysfunction characterized by orthostatic hypotension (OH) and supine hypertension, urinary dysfunction characterized by overactive bladder and incomplete bladder emptying, sexual dysfunction characterized by sexual desire deficiency and erectile dysfunction, and gastrointestinal dysfunction characterized by delayed gastric emptying and constipation, are the main features of MSA. Autonomic dysfunction greatly reduces quality of life and increases mortality. Therefore, early diagnosis and intervention are urgently needed to benefit MSA patients. In this review, we aim to discuss the systematic treatment of autonomic dysfunction in MSA, and focus on the current methods, starting from non-pharmacological methods, such as patient education, psychotherapy, diet change, surgery, and neuromodulation, to various drug treatments targeting autonomic nerve and its projection fibers. In addition, we also draw attention to the interactions among various treatments, and introduce novel methods proposed in recent years, such as gene therapy, stem cell therapy, and neural prosthesis implantation. Furthermore, we elaborate on the specific targets and mechanisms of action of various drugs. We would like to call for large-scale research to determine the efficacy of these methods in the future. Finally, we point out that studies on the pathogenesis of MSA and pathophysiological mechanisms of various autonomic dysfunction would also contribute to the development of new promising treatments and concepts.

Bleeding risk in female patients undergoing intravesical injection of onabotulinumtoxinA for overactive bladder: a Danish retrospective cohort study. Int Urogynecol J 2023; 34:2581-2585. [PMID: 37329356 PMCID: PMC10590281 DOI: 10.1007/s00192-023-05579-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 05/15/2023] [Indexed: 06/19/2023]
Abstract
INTRODUCTION AND HYPOTHESIS We aimed to examine the risk of bleeding in female patients undergoing intravesical onabotulinumtoxinA (BTX-A) treatments and provide clinical recommendations for the perioperative management of patients on antithrombotic therapy prior to BTX-A treatments. METHODS This was a retrospective cohort of Danish female patients, who had their first BTX-A treatment because of an overactive bladder at the Department of Gynecology and Obstetrics, Herlev and Gentofte University Hospital, between January 2015 and December 2020. Data extraction was from an electronic medical journal system. BTX-A, Botox® Allergan was injected in the detrusor at 10-20 sites. Significant bleeding during or after a BTX-A treatment was defined as persistent macroscopic hematuria. Bleeding reporting was based on information obtained from journal notes. RESULTS We included 400 female patients, who had a total of 1,059 BTX-A treatments. Median age at first BTX-A treatment was 70 years (IQR 21), and median number of BTX-A treatments was 2 (range 1-11). In total, 27.8% (n=111) received antithrombotic therapy. Within this group, 30.6% and 69.4% were on anticoagulant and antiplatelet therapy. No cases of hematuria were reported in our cohort. We found that no patients stopped their antithrombotic therapy, were bridged, or monitored by International Normalized Ration (INR) levels. CONCLUSIONS We suggest that BTX-A treatments might be classified as low-risk procedures. Discontinuation of antithrombotic therapy is not required in the perioperative management of this patient group.

Abstract
BACKGROUND Around 16% of adults have symptoms of overactive bladder (OAB; urgency with frequency and/or urge incontinence), with prevalence increasing with age. Anticholinergic drugs are commonly used to treat this condition. This is an update of a Cochrane Review first published in 2002 and last updated in 2006. OBJECTIVES To assess the effects of anticholinergic drugs compared with placebo or no treatment for treating overactive bladder syndrome in adults. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 14 January 2020), and the reference lists of relevant articles. We updated this search on 3 May 2022, but these results have not yet been fully incorporated. SELECTION CRITERIA We included randomised or quasi-randomised trials in adults with overactive bladder syndrome that compared an anticholinergic drug alone with placebo treatment. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility and extracted data from the included studies, including an assessment of the risk of bias. We assessed the certainty of the body of evidence using the GRADE approach. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS We included 104 studies, 71 of which were new or updated for this version of the review. Although 12 studies did not report the number of participants, there were 47,106 people in the remainder of the included studies. The majority of the studies had insufficient information to allow judgement of risk of bias and we judged them to be unclear for all domains. Nine anticholinergic drugs were included in these studies: darifenacin; fesoterodine; imidafenacin; oxybutynin; propantheline; propiverine; solifenacin; tolterodine and trospium. No studies were found that compared anticholinergic drugs to no treatment. At the end of the treatment period, anticholinergics may slightly increase condition-specific quality of life (mean difference (MD) 4.41 lower, 95% confidence interval (CI) 5.28 lower to 3.54 lower (scale range -100 to 0); 12 studies, 6804 participants; low-certainty evidence). Anticholinergics are probably better than placebo in terms of patient perception of cure or improvement (risk ratio (RR) 1.38, 95% CI 1.15 to 1.66; 9 studies, 8457 participants; moderate-certainty evidence), and the mean number of urgency episodes per 24-hour period (MD 0.85 lower, 95% CI 1.03 lower to 0.67 lower; 23 studies, 16,875 participants; moderate-certainty evidence). Compared to placebo, anticholinergics may result in an increase in dry mouth adverse events (RR 3.50, 95% CI 3.26 to 3.75; 66 studies, 38,368 participants; low-certainty evidence), and may result in an increased risk of urinary retention (RR 3.52, 95% CI 2.04 to 6.08; 17 studies, 7862 participants; low-certainty evidence). Taking anticholinergics may be more likely to lead to participants withdrawing from the studies due to adverse events (RR 1.37, 95% CI 1.21 to 1.56; 61 studies, 36,943 participants; low-certainty evidence). However, taking anticholinergics probably reduces the mean number of micturitions per 24-hour period compared to placebo (MD 0.85 lower, 95% CI 0.98 lower to 0.73 lower; 30 studies, 19,395 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS The use of anticholinergic drugs by people with overactive bladder syndrome results in important but modest improvements in symptoms compared with placebo treatment. In addition, recent studies suggest that this is generally associated with only modest improvement in quality of life. Adverse effects were higher with all anticholinergics compared with placebo. Withdrawals due to adverse effects were also higher for all anticholinergics except tolterodine. It is not known whether any benefits of anticholinergics are sustained during long-term treatment or after treatment stops.

Uterine botulinum toxin injections in severe dysmenorrhea, dyspareunia and chronic pelvic pain: Results on quality of life, pain level and medical consumption. Eur J Obstet Gynecol Reprod Biol 2023; 285:164-169. [PMID: 37127000 DOI: 10.1016/j.ejogrb.2023.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 04/20/2023] [Accepted: 04/22/2023] [Indexed: 05/03/2023]
Abstract
OBJECTIVE To evaluate quality of life (Qol), pain level and medical consumption before and after uterine botulinum toxin (BT) injections in severe dysmenorrhea, dyspareunia and chronic pelvic pain. METHODS This was a before and after study using the database of a pilot study (Open-label non comparative study, on 30 patients, with severe dysmenorrhoea in therapeutic failure) assessing efficacy and cost of uterine injection of BT in women with chronic pelvic pain after failure of conventional treatment (hormonal and analgesics) (CT). Main clinical outcome: Patient Global Impression of Improvement (PGI-I), EuroQol health-related QoL (EQ-5D-5L), EuroQol-visual analogue scale (EQ-VAS), Female Sexual Function Index (FSFI), utility measure of health-related quality of life (also called health state preference values), cost and of health care consumption were collected prospectively and analysed in the two phases (before and after). The two timepoints were 12 months before uterine BT injection, when the patient had been receiving CT, and 12 months after uterine BT injection. RESULTS Median visual analogue scale scores were significantly improved by BT regarding the patients' main source of pain (31.6 vs 80.55; p < 0.00001). We also noted a significant reduction in the proportion of patients who reported dyspareunia [15 (75%) vs 3 (15%) patients, p = 0.001] and pain during menstruation (p < 0.0001). The PGI-I scale showed a significant increase in the proportion of patients who were satisfied with their treatment after receiving the BT injection. The injection of BT was frequently associated with increase in QoL and a reduction in health care consumption, and cost: 714.82 €+/- €336.43 (BT) versus 1104.16 €+/- €227.37 (CT), which could result in substantial savings approximately (389,34€) per patient. CONCLUSION This study revealed the clinical effectiveness of BT injections on dysmenorrhea, chronic pelvic pain as well as reduction of cost and health care consumption, in our population, which is innovative since no standard of treatment exists in this domain.

Efficacy of overactive neurogenic bladder treatment: A systematic review of randomized controlled trials. Arch Ital Urol Androl 2022; 94:492-506. [PMID: 36576454 DOI: 10.4081/aiua.2022.4.492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Overactive bladder (OAB) symptoms of frequency, urgency and urge incontinence are frequently associated with known neurological diseases like multiple sclerosis (MS), spinal cord injury (SCI), Parkinson's disease (PD), stroke. OBJECTIVE The aim of our study was to review the efficacy of pharmacological and non-pharmacological treatments for neurogenic overactive bladder. MATERIALS AND METHODS We searched two electronic databases (PubMed and EMBASE) for randomized controlled trials focusing on pharmacological and non-pharmacological medical treatments for overactive bladder symptoms associated with neurological diseases published up to 30 April 2022. RESULTS A total of 157 articles were retrieved; 94 were selected by title and abstract screening; after removal of 17 duplicates, 77 records were evaluated by full-text examination. Sixty-two studies were finally selected. The articles selected for review focused on the following interventions: anticholinergics (n = 9), mirabegron (n = 5), comparison of different drugs (n = 3), cannabinoids (n = 2), intravesical instillations (n = 3), botulinum toxin (n = 16), transcutaneous tibial nerve stimulation (TTNS) (n = 6), acupuncture (n = 2), transcutaneous electrical nerve stimulation TENS (n = 4), pelvic floor muscle training (PFMT) (n = 10), others (n = 2). Anticholinergics were more effective than placebo in decreasing the number of daily voids in patients with PD (mean difference [MD]- 1.16, 95 % CI - 1.80 to - 0.52, 2 trials, 86 patients, p < 0.004), but no significant difference from baseline was found for incontinence episodes and nocturia. Mirabegron was more effective than placebo in increasing the cystometric capacity in patients with MS (mean difference [MD] 89.89 mL, 95 % CI 29.76 to 150.01, 2 trials, 98 patients, p < 0.003) but no significant difference was observed for symptom scores and bladder diary parameters. TTNS was more effective than its sham-control in decreasing the number of nocturia episodes (MD -1.40, 95 % CI -2.39 to -0.42, 2 trials, 53 patients, p < 0.005) but no significant changes of OAB symptom scores were reported. PFMT was more effective than conservative advice in decreasing the ICIQ symptom score (MD, -1.12, 95 % CI -2.13 to -0.11, 2 trials, 91 patients, p = 0.03), although the number of incontinence episodes was not significantly different between groups. CONCLUSIONS The results of the meta-analysis demonstrate a moderate efficacy of all considered treatments without proving the superiority of one therapy over the others. Combination treatment using different pharmacological and non-pharmacological therapies could achieve the best clinical efficacy due to the favorable combination of the different mechanisms of action. This could be associated with fewer side effects due to drug dosage reduction. These data are only provisional and should be considered with caution, due to the few studies included in metaanalysis and to the small number of patients.

Acupuncture for treating overactive bladder in adults. Cochrane Database Syst Rev 2022; 9:CD013519. [PMID: 36148895 PMCID: PMC9502659 DOI: 10.1002/14651858.cd013519.pub2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/12/2023]
Abstract
BACKGROUND Overactive bladder is a common, long-term symptom complex, which includes frequency of micturition, urgency with or without associated incontinence and nocturia. Around 11% of the population have symptoms, with this figure increasing with age. Symptoms can be linked to social anxiety and adaptive behavioural change. The cost of treating overactive bladder is considerable, with current treatments varying in effectiveness and being associated with side effects. Acupuncture has been suggested as an alternative treatment. OBJECTIVES To assess the effects of acupuncture for treating overactive bladder in adults, and to summarise the principal findings of relevant economic evaluations. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (including In-Process, Epub Ahead of Print, Daily), ClinicalTrials.gov and WHO ICTRP (searched 14 May 2022). We also searched the Allied and Complementary Medicine database (AMED) and bibliographic databases where knowledge of the Chinese language was necessary: China National Knowledge Infrastructure (CNKI); Chinese Science and Technology Periodical Database (VIP) and WANFANG (China Online Journals), as well as the reference lists of relevant articles. SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs and cross-over RCTs assessing the effects of acupuncture for treating overactive bladder in adults. DATA COLLECTION AND ANALYSIS Four review authors formed pairs to assess study eligibility and extract data. Both pairs used Covidence software to perform screening and data extraction. We assessed risk of bias using Cochrane's risk of bias tool and assessed heterogeneity using the Chi2 testand I2 statistic generated within the meta-analyses. We used a fixed-effect model within the meta-analyses unless there was a moderate or high level of heterogeneity, where we employed a random-effects model. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 15 studies involving 1395 participants in this review (14 RCTs and one quasi-RCT). All included studies raised some concerns regarding risk of bias. Blinding of participants to treatment group was only achieved in 20% of studies, we considered blinding of outcome assessors and allocation concealment to be low risk in only 25% of the studies, and random sequence generation to be either unclear or high risk in more than 50% of the studies. Acupuncture versus no treatment One study compared acupuncture to no treatment. The evidence is very uncertain regarding the effect of acupuncture compared to no treatment in curing or improving overactive bladder symptoms and on the number of minor adverse events (both very low-certainty evidence). The study report explicitly stated that no major adverse events occurred. The study did not report on the presence or absence of urinary urgency, episodes of urinary incontinence, daytime urinary frequency or episodes of nocturia. Acupuncture versus sham acupuncture Five studies compared acupuncture with sham acupuncture. The evidence is very uncertain about the effect of acupuncture on curing or improving overactive bladder symptoms compared to sham acupuncture (standardised mean difference (SMD) -0.36, 95% confidence interval (CI) -1.03 to 0.31; 3 studies; 151 participants; I2 = 65%; very low-certainty evidence). All five studies explicitly stated that there were no major adverse events observed during the study. Moderate-certainty evidence suggests that acupuncture probably makes no difference to the incidence of minor adverse events compared to sham acupuncture (risk ratio (RR) 1.28, 95% CI 0.30 to 5.36; 4 studies; 222 participants; I² = 0%). Only one small study reported data for the presence or absence of urgency and for episodes of nocturia. The evidence is of very low certainty for both of these outcomes and in both cases the lower confidence interval is implausible. Moderate-certainty evidence suggests there is probably little or no difference in episodes of urinary incontinence between acupuncture and sham acupuncture (mean difference (MD) 0.55, 95% CI -1.51 to 2.60; 2 studies; 121 participants; I2 = 57%). Two studies recorded data regarding daytime urinary frequency but we could not combine them in a meta-analysis due to differences in methodologies (very low-certainty evidence). Acupuncture versus medication Eleven studies compared acupuncture with medication. Low-certainty evidence suggests that acupuncture may slightly increase how many people's overactive bladder symptoms are cured or improved compared to medication (RR 1.25, 95% CI 1.10 to 1.43; 5 studies; 258 participants; I2 = 19%). Low-certainty evidence suggests that acupuncture may reduce the incidence of minor adverse events when compared to medication (RR 0.34, 95% CI 0.26 to 0.45; 8 studies; 1004 participants; I² = 51%). The evidence is uncertain regarding the effect of acupuncture on the presence or absence of urinary urgency (MD -0.40, 95% CI -0.56 to -0.24; 2 studies; 80 participants; I2 = 0%; very low-certainty evidence) and episodes of urinary incontinence (MD -0.33, 95% CI -2.75 to 2.09; 1 study; 20 participants; very low-certainty evidence) compared to medication. Low-certainty evidence suggests there may be little to no effect of acupuncture compared to medication in terms of daytime urinary frequency (MD 0.73, 95% CI -0.39 to 1.85; 4 studies; 360 participants; I2 = 28%). Acupuncture may slightly reduce the number of nocturia episodes compared to medication (MD -0.50, 95% CI -0.65 to -0.36; 2 studies; 80 participants; I2 = 0%, low-certainty evidence). There were no incidences of major adverse events in any of the included studies. However, major adverse events are rare in acupuncture trials and the numbers included in this review may be insufficient to detect these events. AUTHORS' CONCLUSIONS The evidence is very uncertain about the effect acupuncture has on cure or improvement of overactive bladder symptoms compared to no treatment. It is uncertain if there is any difference between acupuncture and sham acupuncture in cure or improvement of overactive bladder symptoms. This review provides low-certainty evidence that acupuncture may result in a slight increase in cure or improvement of overactive bladder symptoms when compared with medication and may reduce the incidence of minor adverse events. These conclusions must remain tentative until the completion of larger, higher-quality studies that use relevant, comparable outcomes. Timing and frequency of treatment, point selection, application and long-term follow-up are other areas relevant for research.

Conservative interventions for treating urinary incontinence in women: an Overview of Cochrane systematic reviews. Cochrane Database Syst Rev 2022; 9:CD012337. [PMID: 36053030 PMCID: PMC9437962 DOI: 10.1002/14651858.cd012337.pub2] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/27/2023]
Abstract
BACKGROUND Urinary incontinence (UI) is the involuntary loss of urine and can be caused by several different conditions. The common types of UI are stress (SUI), urgency (UUI) and mixed (MUI). A wide range of interventions can be delivered to reduce the symptoms of UI in women. Conservative interventions are generally recommended as the first line of treatment. OBJECTIVES To summarise Cochrane Reviews that assessed the effects of conservative interventions for treating UI in women. METHODS We searched the Cochrane Library to January 2021 (CDSR; 2021, Issue 1) and included any Cochrane Review that included studies with women aged 18 years or older with a clinical diagnosis of SUI, UUI or MUI, and investigating a conservative intervention aimed at improving or curing UI. We included reviews that compared a conservative intervention with 'control' (which included placebo, no treatment or usual care), another conservative intervention or another active, but non-conservative, intervention. A stakeholder group informed the selection and synthesis of evidence. Two overview authors independently applied the inclusion criteria, extracted data and judged review quality, resolving disagreements through discussion. Primary outcomes of interest were patient-reported cure or improvement and condition-specific quality of life. We judged the risk of bias in included reviews using the ROBIS tool. We judged the certainty of evidence within the reviews based on the GRADE approach. Evidence relating to SUI, UUI or all types of UI combined (AUI) were synthesised separately. The AUI group included evidence relating to participants with MUI, as well as from studies that combined women with different diagnoses (i.e. SUI, UUI and MUI) and studies in which the type of UI was unclear. MAIN RESULTS We included 29 relevant Cochrane Reviews. Seven focused on physical therapies; five on education, behavioural and lifestyle advice; one on mechanical devices; one on acupuncture and one on yoga. Fourteen focused on non-conservative interventions but had a comparison with a conservative intervention. No reviews synthesised evidence relating to psychological therapies. There were 112 unique trials (including 8975 women) that had primary outcome data included in at least one analysis. Stress urinary incontinence (14 reviews) Conservative intervention versus control: there was moderate or high certainty evidence that pelvic floor muscle training (PFMT), PFMT plus biofeedback and cones were more beneficial than control for curing or improving UI. PFMT and intravaginal devices improved quality of life compared to control. One conservative intervention versus another conservative intervention: for cure and improvement of UI, there was moderate or high certainty evidence that: continence pessary plus PFMT was more beneficial than continence pessary alone; PFMT plus educational intervention was more beneficial than cones; more-intensive PFMT was more beneficial than less-intensive PFMT; and PFMT plus an adherence strategy was more beneficial than PFMT alone. There was no moderate or high certainty evidence for quality of life. Urgency urinary incontinence (five reviews) Conservative intervention versus control: there was moderate to high-certainty evidence demonstrating that PFMT plus feedback, PFMT plus biofeedback, electrical stimulation and bladder training were more beneficial than control for curing or improving UI. Women using electrical stimulation plus PFMT had higher quality of life than women in the control group. One conservative intervention versus another conservative intervention: for cure or improvement, there was moderate certainty evidence that electrical stimulation was more effective than laseropuncture. There was high or moderate certainty evidence that PFMT resulted in higher quality of life than electrical stimulation and electrical stimulation plus PFMT resulted in better cure or improvement and higher quality of life than PFMT alone. All types of urinary incontinence (13 reviews) Conservative intervention versus control: there was moderate to high certainty evidence of better cure or improvement with PFMT, electrical stimulation, weight loss and cones compared to control. There was moderate certainty evidence of improved quality of life with PFMT compared to control. One conservative intervention versus another conservative intervention: there was moderate or high certainty evidence of better cure or improvement for PFMT with bladder training than bladder training alone. Likewise, PFMT with more individual health professional supervision was more effective than less contact/supervision and more-intensive PFMT was more beneficial than less-intensive PFMT. There was moderate certainty evidence that PFMT plus bladder training resulted in higher quality of life than bladder training alone. AUTHORS' CONCLUSIONS There is high certainty that PFMT is more beneficial than control for all types of UI for outcomes of cure or improvement and quality of life. We are moderately certain that, if PFMT is more intense, more frequent, with individual supervision, with/without combined with behavioural interventions with/without an adherence strategy, effectiveness is improved. We are highly certain that, for cure or improvement, cones are more beneficial than control (but not PFMT) for women with SUI, electrical stimulation is beneficial for women with UUI, and weight loss results in more cure and improvement than control for women with AUI. Most evidence within the included Cochrane Reviews is of low certainty. It is important that future new and updated Cochrane Reviews develop questions that are more clinically useful, avoid multiple overlapping reviews and consult women with UI to further identify outcomes of importance.

Abstract
INTRODUCTION AND HYPOTHESIS We hypothesized that patients with refractory overactive bladder (rOAB) have similar improvement with percutaneous tibial nerve stimulation (PTNS) and OnabotulinumtoxinA (BTX). METHODS This multicenter cohort study compared BTX and PTNS in women with rOAB. Baseline information included Overactive Bladder Questionnaire (OABq) short form, Urinary Distress Inventory-6 (UDI-6), and voiding diary. Primary outcome was cure, defined as "very much better" or "much better" on the Patient Global Impression of Improvement (PGII) AND a reduction in OABq symptom severity scale (SSS) ≥10 at 3 months after treatment. Assuming 80% power to detect a ten-point difference in OABq-SSS, 80 participants were required per group. RESULTS A total of 150 patients were enrolled; 97 completed 3 months of therapy and were included. At baseline, BTX patients had more detrusor overactivity (70% vs 40%, p = 0.025), urgency incontinence (UUI; OABq-SSS#6 4 vs 3, p = 0.02, SSS 65 vs 56, p = 0.04), but similar health-related quality of life (HRQL 49 vs 54, p = 0.28), voids (7 vs 8, p = 0.13), and UUI episodes (2 vs 2, p = 1.0). At 3 months, cure rates were similar: BTX 50% vs PTNS 44.2% (p = 0.56). Both groups had improved SSS (-37 vs -29, p = 0.08) and HRQL (31 vs 24, p = 0.14). Patients receiving BTX had a greater improvement in urgency (ΔOABq-SSS#2-3 vs -2; p = 0.02) and UUI (ΔOABq-SSS#6-2 vs -1; p = 0.02). No characteristics were predictive of cure. CONCLUSIONS BTX resulted in significantly greater improvement in urgency and UUI than PTNS, but no difference in success based on PGII and OABq-SSS, which may be due to a lack of power.

Abstract
Objective: Overactive bladder (OAB) is a disease characterized by the presence of urinary urgency. We carried out a meta-analysis to assess the effectiveness and safety of trigonal-involved injection of onabotulinumtoxinA (BoNT-A) in comparison with the trigonal-sparing technique in cases with OAB [neurogenic detrusor overactivity (NDO) and idiopathic detrusor overactivity (IDO)]. Methods: Randomized controlled trials (RCTs) of BoNT-A injection for OAB were searched systematically by using EMBASE, MEDLINE, and the Cochrane Controlled Trials Register. The datum was calculated by RevMan version 5.3.0. The original references of relating articles were also reviewed. Results: In total, six RCTs involving 437 patients were included in our analysis. For OAB, the trigone-including group showed a different patient symptom score (p = 0.03), complete dryness rate (p = 0.002), frequency of incontinence episodes (p = 0.01), detrusor pressure at maximum flow rate (p = 0.01), and volume at the first desire to void (p = 0.0004) compared with the trigone-sparing group. Also, a trigone-including intradetrusor injection demonstrated a significant improvement in the patient symptom score (p = 0.0004), complete dryness rate (p = 0.0002), frequency of incontinence episodes (p = 0.0003), detrusor pressure at maximum flow rate (p = 0.01), and volume at the first desire to void (p = 0.00006) compared with the trigone-sparing group for treatment of NDO. The adverse events rates were similar in both groups. Conclusions: The meta-analysis has demonstrated that trigone-including BoNT-A injection was more effective compared with the trigone-sparing injection for the treatment of OAB, especially for NDO.

In Patients with Neurogenic Detrusor Overactivity and Hinman's Syndrome: Would Intravesical Botox Injections Decrease the Incidence of Symptomatic Urinary Tract Infections. Res Rep Urol 2021; 13:659-663. [PMID: 34513743 PMCID: PMC8421780 DOI: 10.2147/rru.s317361] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Accepted: 08/23/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose To study the effect of intravesical Botox injection on the incidence of recurrent symptomatic UTI in neurogenic bladder patients with detrusor overactivity. Patients and Methods This was a prospective cohort study for patients who received Botox intravesical injection. We included patients with neurogenic bladder with detrusor overactivity and symptomatic recurrent UTI. We compared the number of symptomatic UTIs at six months pre- and post-intravesical Botox injection. Patient files were reviewed for diagnosis, vesico-uretric reflux, hydronephrosis, urodynamic findings pre- and post-injection, and dose of Botox used. Patients were followed for the number of symptomatic UTIs post-Botox injection. Results There were 93 patients diagnosed with neurogenic detrusor overactivity and symptomatic recurrent UTI. Patients were categorized into three categories: Group 1 – adults, Group 2 – pediatrics, Group 3 – non-neurogenic neurogenic bladder (Hinman’s syndrome). Spina bifida was diagnosed in 22 adults (Group 1) and 32 pediatric patients (Group 2). After receiving Botox injection, 75% of all patients (70) had a significant decrease in number of symptomatic UTIs. Urodynamic tests post-injection showed an improvement in bladder capacity, compliance, and detrusor pressure versus baseline in all three groups. Correlation analysis showed significant correlation between decreased symptomatic UTI post-Botox injection and detrusor pressure post-injection as well as bladder compliance; p-value=0.01 and p=0.021, respectively. Conclusion Intravesical Botox injection may decrease incidence of symptomatic UTI in neurogenic detrusor overactivity. This effect seemed to be related to better bladder management.

Cost-Utility Analysis of Oxybutynin vs. OnabotulinumtoxinA (Botox) in the Treatment of Overactive Bladder Syndrome. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168743. [PMID: 34444493 PMCID: PMC8394450 DOI: 10.3390/ijerph18168743] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 07/31/2021] [Accepted: 08/06/2021] [Indexed: 11/18/2022]
Abstract
Background: The UK National Health Service (NHS) propose the use of oxybutynin prior to onabotulinumtoxinA (Botox) in the management of overactive bladder syndrome (OAB). Oxybutynin is costly and associated with poor adherence, which may not occur with Botox. We conducted a cost-utility analysis (CUA) to compare the medications. Methods: we compared the two treatments in quality-adjusted life years (QALYS), through the NHS’s perspective. Costs were obtained from UK-based sources and were discounted. Total costs were determined by adding the treatment cost and management cost for complications on each branch. A 12-month time frame was used to model the data into a decision tree. Results: Our results found that using Botox first-line had greater cost utility than oxybutynin. The health net benefit calculation showed an increase in 0.22 QALYs when Botox was used first-line. Botox also had greater cost-effectiveness, with the exception of pediatric patients with an ICER of £42,272.14, which is above the NICE threshold of £30,000. Conclusion: Botox was found to be more cost-effective than antimuscarinics in the management of OAB in adults, however less cost-effective in younger patients. This predicates the need for further research to ascertain the age at which Botox becomes cost-effective in the management of OAB.

Outcomes of a single trigone-only vs. 20 trigone-sparing injections of OnabotulinumtoxinA for refractory overactive bladder (OAB). Int Urol Nephrol 2021; 53:1067-1072. [PMID: 33742316 DOI: 10.1007/s11255-021-02802-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 02/08/2021] [Indexed: 01/23/2023]
Abstract
PURPOSE To compare the safety and durability of a single intravesical trigonal-only versus 20 trigone-sparing injections of OnabotulinumtoxinA (BTA) for refractory OAB. METHODS A chart review of all idiopathic OAB patients treated with BTA from January 2016 to December 2018 was performed. Outcomes measures included: inter-injection interval, post-void residual (PVR), urinary tract infections (UTI), urinary retention requiring catheterization, and procedure time (min). Statistical analyses were performed using independent sample t-tests. RESULTS Baseline characteristics were comparable for the two groups, data on 69 treatments (19 patients trigone-only) were compared to 105 treatments (26 patients trigone-sparing). There were no differences in the inter-injection intervals or rates of UTI. The trigone-only group exhibited a lower mean PVR (113 ml vs 160 ml, p < 0.02), lower proportion with PVR > 150 ml (23% vs. 39%, p < 0.03), lower rate of urinary retention (5.3% vs. 17.4%, p < 0.02), and shorter procedure time (4.3 min vs. 5.7 min, p < 0.01). There were no cases of vesico-ureteral reflux. CONCLUSION While interpretation remains speculative, the results of this observational study suggest that a single trigone-only injection appears to be as safe and durable as multiple trigone-sparing injections but maybe quicker to perform and appears to have a lower impact on voiding function. Larger series and adequately powered prospective randomized clinical trials are warranted to validate the findings of this pilot study.

Abstract
A wide range of dysfunction can occur after a stroke including symptoms such as urinary urgency, frequency, and urge incontinence. The Spinal Cord Neuromodulator (SCONETM) reactivates and retrains spinal neural networks. The present case study introduces initial evidence that home-based, self-administered SCONE therapy may be a safe and effective method of delivering this neuromodulation modality and may have the ability to minimize clinic visits, which is especially salient in today's public health environment.

Efficacy and Safety of Vibegron Add-on Therapy in Men With Persistent Storage Symptoms After Receiving Alpha 1-Blocker or Phosphodiesterase 5 Inhibitor: A Preliminary Study. Urology 2021; 153:256-263. [PMID: 33484823 DOI: 10.1016/j.urology.2021.01.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Revised: 12/30/2020] [Accepted: 01/11/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To investigate the efficacy and safety of vibegron add-on therapy in men with persistent storage symptoms receiving α-1 blockers or PDE5 inhibitor for benign prostatic hyperplasia and then determine the independent factors affecting the efficacy of vibegron. METHODS Vibegron 50 mg was administered for 12 weeks to 42 patients (72.0 ± 8.2 years) with persistent storage symptoms who had taken α-1 blockers (22 patients) or PDE5 inhibitor (20 patients). The primary endpoint was change in the overactive Bladder (OAB) Symptom Score from baseline to end of treatment. The secondary endpoints were changes in each question of several questionnaires, maximum flow rate and residual urine volume. Finally, independent factors affecting the efficacy of vibegron were investigated. RESULTS Total OAB Symptom Score was significantly decreased (6.21 ± 3.12 vs 4.38 ± 2.46; P < .001). Although each score of several questionnaires, especially for storage symptoms, improved significantly, no significant improvement was found in stress incontinence, straining, bladder pain and urethral pain in the Core Lower Urinary Tract Symptom score. Maximum flow rate and residual urine volume did not change, and no patient discontinued vibegron because of adverse events. Multiple regression analysis showed that OAB Symptom Score, Core Lower Urinary Tract Symptom score, prostate volume and monotherapy with α-1 blocker were independent factors affecting the efficacy of vibegron. CONCLUSION Add-on therapy of vibegron to monotherapy with α-1 blockers or PDE5 inhibitor for patients with benign prostatic hyperplasia and persistent storage symptoms was effective and safe.

Abstract
Background: Botulinum toxin is an injectable neuromodulator that inhibits transmission between peripheral nerve endings and muscle fibers, resulting in muscle paralysis. Botulinum toxin type A is the most common form of botulinum toxin used in clinical practice. Methods: In this review, we examine the mechanism of action, formulations, common clinical use in the genital-urinary tract, and potential clinical use in pelvic floor disorders of botulinum toxin type A. Results: Several aspects of botulinum toxin A make it a favorable therapeutic tool, including its accessibility, its longevity, and its impermanence and reversibility of resultant chemodenervation in a relatively short and safe manner. Although botulinum toxin A has well-established efficacy in treating refractory overactive bladder and neurogenic detrusor overactivity, its use in pelvic floor disorders is still in its infancy. Conclusion: The efficacy of botulinum toxin A for treating pelvic pain, voiding dysfunction, muscle pain and dysfunction, and certain colorectal-related pain issues shows promise but requires additional rigorous evaluation.

Abstract
Hintergrund Die minimal-invasive Donornephrektomie (DN) ist inzwischen operativer Standard, bezüglich der Rolle von roboterassistierten Verfahren gibt es bisher keinen Konsens. Fragestellung Die ersten 50 transperitonealen roboterassistierten Donornephrektomien (RDN) einer urologischen Universitätsklinik in Deutschland wurden retrospektiv ausgewertet. Material und Methoden Patientencharakteristika, intra- und postoperative Parameter wurden erfasst und die Nierenfunktion in einem 5‑jährigen Follow-up ausgewertet. Signifikante Prädiktoren für die Nierenfunktion bei Entlassung und ein Jahr postoperativ wurden in einem multivariablen Regressionsmodell bestimmt. Ergebnisse Die RDN hat exzellente Ergebnisse mit niedriger Komplikationsrate, kurzer warmer (WIZ) und kalter Ischämiezeit (KIZ) sowie geringem Blutverlust und kurzer Patientenverweildauer. Die Seite der Nierenentnahme hat hierauf keine Auswirkungen. Nach RDN sind etwa 50 % der Spender formal niereninsuffizient, was aber zumeist ohne Relevanz ist, weil sich die Nierenfunktion der Spender im Follow-up nicht weiter verschlechtert. Die postoperative Nierenfunktion lässt sich bei der RDN mithilfe der präoperativen eGFR (errechnete glomeruläre Filtrationsrate) und dem Spenderalter sehr gut vorhersagen. Schlussfolgerungen Die robotische DN stellt eine sehr gute Alternative zu anderen minimal-invasiven Operationsverfahren dar, die von Beginn an exzellente operative Ergebnisse ermöglicht.

Abstract
INTRODUCTION The prevalence of urinary incontinence and of other lower urinary tract symptoms increases after the menopause and affects between 38 % and 55 % of women aged over 60 years. While urinary incontinence has a profound impact on quality of life, few affected women seek care. AIM The aim of this clinical guide is to provide an evidence-based approach to the management of urinary incontinence in postmenopausal women. MATERIALS AND METHODS Literature review and consensus of expert opinion. SUMMARY RECOMMENDATIONS Healthcare professionals should consider urinary incontinence a clinical priority and develop appropriate diagnostic skills. They should be able to identify and manage any relevant modifiable factors that could alleviate the condition. A wide range of treatment options is available. First-line management includes lifestyle and behavioral modification, pelvic floor exercises and bladder training. Estrogens and other pharmacological interventions are helpful in the treatment of urgency incontinence that does not respond to conservative measures. Third-line therapies (e.g. sacral neuromodulation, intravesical onabotulinum toxin-A injections and posterior tibial nerve stimulation) are useful in selected patients with refractory urge incontinence. Surgery should be considered in postmenopausal women with stress incontinence. Midurethral slings, including retropubic and transobturator approaches, are safe and effective and should be offered.

Abstract
Overactive bladder syndrome (OAB) is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency incontinence, in the absence of urinary tract infection or other obvious pathology. In this review, we focus on recent advances in the management of OAB. We examine the evidence on the effect of anticholinergic load on OAB patients. Advances in medical treatment include a new beta-3 agonist, vibegron, which is thought to have fewer drug interactions than mirabegron. Treatment of genitourinary syndrome of the menopause with oestrogens and ospemifene have also shown promise for OAB. Botulinum toxin has been shown to be an effective treatment option. We discuss the new implantable neuromodulators that are on the market as well as selective bladder denervation and laser technology.

Abstract
Botulinum toxins are neurotoxic modular proteins composed of a heavy chain and a light chain connected by a disulfide bond and are produced by Clostridium botulinum. Although lethally toxic, botulinum toxin in low doses is clinically effective in numerous medical conditions, including muscle spasticity, strabismus, hyperactive urinary bladder, excessive sweating, and migraine. Globally, several companies are now producing products containing botulinum toxin for medical and cosmetic purposes, including the reduction of facial wrinkles. To test the efficacy and toxicity of botulinum toxin, animal tests have been solely and widely used, resulting in the inevitable sacrifice of hundreds of animals. Hence, alternative methods are urgently required to replace animals in botulinum toxin testing. Here, the various alternative methods developed to test the toxicity and efficacy of botulinum toxins have been briefly reviewed and future perspectives have been detailed.

Predictors of Poor Response and Adverse Events Following Botulinum Toxin A for Refractory Idiopathic Overactive Bladder: A Systematic Review. Eur Urol Focus 2020; 7:1448-1467. [PMID: 32616412 DOI: 10.1016/j.euf.2020.06.013] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Revised: 06/02/2020] [Accepted: 06/22/2020] [Indexed: 10/24/2022]
Abstract
CONTEXT Botulinum toxin A (BTX-A) injections are effective in managing refractory overactive bladder (OAB). However, some patients exhibit a poor response and/or experience adverse events (AEs) such as voiding dysfunction necessitating clean intermittent self-catheterisation (CISC) and urinary tract infections (UTIs). OBJECTIVE To systematically evaluate whether poor response/AEs to BTX-A for idiopathic OAB are predictable. EVIDENCE ACQUISITION MEDLINE, EMBASE, and Google Scholar database were searched in March 2020. Studies reporting predictive factors for poor response or AEs were included. Two reviewers independently screened articles, searched references, and extracted data. Risk of bias (Quality in Prognosis Studies [QUIPS]) and quality of evidence (Grading of Recommendations Assessment, Development and Evaluation [GRADE]) tools were utilised. EVIDENCE SYNTHESIS Of 1579 articles, 17 met the inclusion criteria. These were cohort studies with predominantly level 3 evidence. Factors including male gender, frailty, comorbidity, increasing age, smoking, baseline leakage episodes, and various urodynamic parameters (bladder outlet obstruction index [BOOI], high pretreatment maximum detrusor pressure, and poor bladder compliance) were proposed as predictors of nonresponse. In predicting CISC use, male gender, comorbidity, increasing age, number of vaginal deliveries, hysterectomy, and urodynamic parameters (bladder capacity, postvoid residual volume, projected isovolumetric pressure value, bladder contractility index, and BOOI) were implicated. Female gender, males with their prostates in situ, and CISC were suggested to increase UTIs after BTX-A. CONCLUSIONS This review has identified factors that may predict poor response/AEs following bladder BTX-A and help in counselling of patients. Overall, the quality of individual studies included was poor, limiting the certainty of evidence reported. Larger-scale, better-designed trials with uniform definitions of poor response are required to confirm these preliminary findings. PATIENT SUMMARY This review assessed whether we could predict poor response or side effects to bladder botulinum toxin A injections in managing overactive bladder. Many different factors based on the patient, medical conditions, previous surgery, and pretreatment investigations were identified. However, the quality of included studies was generally poor, limiting their conclusions.

Abstract
Introduction Recent investigations showed that anticholinergic drugs could use for the management of storage symptoms after transurethral resection of the prostate (TURP). The use of intravesical botulinum toxin-A (BTX-A) for the management of overactive bladder is rapidly increasing. In this research, we assess the efficacy of BTX-A vs solifenacin in men suffering from bladder outlet obstruction–over active bladder (BOO-OAB) managed with TURP. Methods In this case–control study, 50 men with BOO-OAB randomized into two groups. The control group (A) underwent TURP and subsequently managed by solifenacin 5 mg daily, and the case group (B) underwent TURP and BTX-A injection in the bladder wall in the same session. Treatment success was the primary outcome and defined as post-injection improvement in the storage score of the International Prostate Symptom Score (IPSS) from baseline. Results The IPSS, post-void residual volume, frequency, incomplete emptying, nocturia and urgency subscores considerably ameliorated after 12 weeks and 36 weeks for both groups, but it was more significant in the case arm. The quality of life (QoL) scores significantly improved after the treatments in both groups. Intervention group showed significant reductions regarding urgency incontinence compared with the solifenacin group at 12th and 36th weeks. Conclusion BTX-A is an effective and well-tolerated treatment in patients with benign prostatic hyperplasia (BPH) who are candidates of TURP and simultaneously suffer from OAB symptoms.

Abstract
Botulinum toxin is a substance produced by Clostridium Botulinum and is responsible for human botulism. This substance is a poison, a neurotoxin, but used in limited quantities it can be a cure for some diseases. It is well connected to a large variety of medical applications. The mechanism of action relies on blocking the acetylcholine at the neuromuscular junction, which blocks the transmission of the nervous impulse with secondary flaccid paralysis. In urology, its role in idiopathic overactive bladder and neurogenic bladder is well known. We performed a thorough review using PubMed and other databases, revising the mechanisms of botulinum toxin action in urologic pathology, treatment procedures and other options. Botulinum toxin is a well-studied substance with a large number of applications in medicine. In urologic pathology, overactive bladder and neurogenic bladder are backed by robust studies that support the therapeutic role of this substance. The toxin has multiple effects, such as inhibition of the nerve growth factor, blocking the bladder sensory afferent pathway and apoptotic effect on the prostate tissue, by inhibiting the substance P, altering the nociceptive pathways. Interstitial cystitis and other rare pathologies show promising results, but further studies are needed. The role of botulinum toxin in benign prostatic hyperplasia is still not elucidated.

Abstract
INTRODUCTION AND OBJECTIVE The use of intravesical onabotulinum-A toxin (BoNT-A) injections in the treatment of idiopathic detrusor overactivity has been widely studied in adults [2-5]. However, in pediatric populations, study groups are small, and results are not yet sufficient to support this treatment as a standard practice. The aim of this study is to determine the effectiveness and safety of this treatment in children with non-neurogenic detrusor overactivity, resistant to conservative therapy. MATERIAL AND METHODS We retrospectively evaluated the effect and safety of the intradetrusor injection of 100 Units (U) of BoNT-A in 257 children with therapy-resistant non-neurogenic detrusor overactivity between May 2003 and August 2017. Outcome parameters were the number of daytime incontinence and enuresis episodes per week and bladder capacity (BC). Treatment outcomes were classified into complete response, partial response, or no response. RESULTS The database includes 257 children, of which are 102 girls and 155 boys. Median age of first BoNT-A injection was 8 years (range 4-18 years). Of the patients with enuresis, daytime incontinence or both, a complete response was seen in 50%, 45.7%, and 17%, respectively. BC was significantly higher after the first, second, and third injection of 100 U BoNT-A. We estimated that the mean duration of the effect of an injection with a dose of 100 U is around 12 months. After the first injection, one girl (0.4%) developed urinary retention, which required temporary clean intermittent catheterization (CIC). Seventeen patients (6.6%) developed a urinary tract infection. In three patients (1.2%), postoperative vesicoureteral reflux was seen. DISCUSSION A distinction between the effect on daytime incontinence and enuresis was made. A poorer effect on enuresis in children who suffered from both conditions was observed. Drawbacks of this study are its retrospective design and the lack of anticholinergic treatment standardization before and after BoNT-A injection. CONCLUSION BoNT-A injection is a potentially effective adjuvant therapy in the treatment of children with therapy-resistant overactive bladder (OAB). Bladder capacity increases significantly after the first, second, and third injections. A better effect on daytime incontinence than on enuresis was seen. Prospective randomized trials with standardization of conservative treatment and symptoms questionnaires are necessary to confirm the beneficial effect of BoNT-A injections on BC and incontinence.

Abstract
Overactive bladder syndrome (OAB) is defined by the presence of urinary urgency, with or without urge incontinence, usually accompanied by an increase in urinary frequency and nocturia in the absence of urinary tract infections (UTI) or other diseases. The overall prevalence of OAB symptoms in the female population is reported to be 16.6% and increases with advancing age and menopause. The aetiology of OAB is not fully understood and is likely to affect a heterogeneous population of patients due to changes to their central and peripheral nervous systems. Although OAB is frequently associated with female sexual dysfunction (FSD), its real impact on sexual function in women has been evaluated only in a few studies. The first line of treatment for OAB includes behavioural modification and physical therapy, either as monotherapies or in combination. Many patients who have not had success in managing their symptoms with more conservative therapies may decide to resort to third-line treatments for refractory OAB. These treatments include neuromodulation therapies, particularly transvaginal electrical stimulation (TES) and sacral neuromodulation (SN). The aim of this short commentary is to provide an overview of the effectiveness of these treatments and of their impact on quality of life, body image, sexual function, and emotional well-being.

Abstract
INTRODUCTION AND HYPOTHESIS Intradetrusor onabotulinumtoxinA (BTX) and sacral neuromodulation (SNM) are effective treatments for refractory urgency urinary incontinence/overactive bladder (UUI/OAB). BTX carries a risk of urinary tract infection (UTI), which is concerning for the development of multidrug resistant (MDR) UTI. We hypothesized that BTX might carry a higher risk of UTI and MDR UTI compared with SNM and that UTI and MDR UTI risk might increase after repeat BTX injection. METHODS This retrospective cohort study included women undergoing BTX or SNM for refractory UUI/OAB in 2012-2016. UTI and MDR UTI were assessed up to 1 year post-treatment or until repeat treatment and compared between initial BTX and SNM and between repeat BTX injections. Univariate analyses included Chi-squared and Fisher's exact tests and generalized linear models (GLM) with logit link function. Multivariate analyses used GLM to assess the best predictor variables for any UTI. RESULTS One hundred and one patients were included (28 BTX, 73 SNM). Rates of UTI (39.3% [95% CI 21.5, 59.4] BTX vs 37.0% [95% CI 26.0, 49.1] SNM) were similar in the two groups at all time intervals. One MDR UTI occurred after SNM. Risk of UTI did not increase with repeat BTX (11 out of 28 [39.3%], 6 out of 17 [35.3%], and 4 out of 7 [57.1%] after 1, 2, and ≥ 3 treatments respectively; p = 0.62). Multivariate analysis found that history of recurrent UTI (OR 2.5, 95%CI 0.98-6.39) and prolapse repair (OR 4.6, 95%CI 1.23-17.07) had increased odds of UTI. CONCLUSIONS Rates of UTI were similar in patients undergoing BTX and SNM. MDR UTI was rare. Patients with prior prolapse repair or recurrent UTI may be at a higher risk of UTI after either procedure.

Abstract
Urinary incontinence is a common, often undertreated, condition that impacts millions of Americans. Primary care physicians are well equipped to diagnose and treat urinary incontinence. Key to successful treatment is accurately determining the type of incontinence that ails the patient and using patient-reported quality-of-life indicators to guide stepwise treatment.

Abstract
The symptoms of overactive bladder (OAB) can be treated with oral medications using a variety of antimuscarinic medications and, more recently, mirabegron, a beta-3 agonist. However, the use of these medications may be limited for patients because of adverse drug reactions, contraindications, and those who are refractory to oral medications. Recently, intravesical injections of onabotulinumtoxinA (onaBoNTA) have been proven to be safe and effective as an alternative to oral OAB medications. Although this procedure is typically thought to be outside the realm of a consultant pharmacist, there are incidences in which a pharmacist can make a substantial impact on patient care. The patient, a 71-year old female, presents to her urologist for evaluation to assess appropriateness of intravesical onaBoNTA injections. She has failed multiple oral medications for the treatment of her OAB with urge incontinence. The procedure is further complicated by the patient's past medical history of atrial fibrillation (A fib), deep vein thrombosis (DVT), and pulmonary embolism (PE) that require anticoagulation with warfarin therapy. This case demonstrates the use of onaBoNTA for OAB in a patient concomitantly receiving warfarin for A fib, PE, and DVT. Specifically, it demonstrates discontinuation, bridge therapy, and reinitiation of warfarin on a patient undergoing intravesical injections of onaBoNTA for OAB, and a collaborative approach to care between a pharmacist and a urologist.

Objective and subjective improvement in children with idiopathic detrusor overactivity after intravesical botulinum toxin injection: A preliminary report. J Pediatr Surg 2019; 54:595-599. [PMID: 29887168 DOI: 10.1016/j.jpedsurg.2018.05.012] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2018] [Revised: 05/15/2018] [Accepted: 05/18/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVE The purpose of this study is to evaluate the effect of Intravesical Botulinum toxin injection on the symptoms and urodynamic parameters in pediatric patients with idiopathic overactive bladder (iOAB) refractory to medical treatment. MATERIALS AND METHODS The study was designed as an open-label uncontrolled therapeutic clinical trial. The eligible patients who underwent Intravesical botulinum toxin injection were evaluated before treatment. The evaluation included a 7-day paper bladder diary to assess OAB symptoms (frequency, urgency urinary incontinence (UUI) and nocturnal enuresis (NE)), filling the Arabic International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI short form), and conducting urodynamic study. The Urodynamic parameters obtained were the maximum filling detrusor pressure, cystometric bladder capacity, and compliance. After 12 weeks of the intravesical injection, the patients were revaluated and the results were compared using paired samples t-test. RESULTS The study enrolled 75 patients. And of those, statistical analysis was done on 46 patients who did follow the study protocols. The mean age was 8.9 years and male to female ratio was 1:4. There was a statistically significant improvement in overactive bladder symptoms and urodynamic parameters in the patient injected with botulinum toxin with minimal side effects. CONCLUSION The evidence in this study would support the safety and efficacy of Intravesical botulinum toxin injection in children with refractory idiopathic OAB with significant improvement of symptoms, quality of life, as well as urodynamic parameters. TYPE OF STUDY Open-label uncontrolled therapeutic clinical trial. LEVEL OF EVIDENCE III.

Modifications to Botulinum toxin A delivery in the management of detrusor overactivity recalcitrant to initial injections: a review. World J Urol 2018; 37:891-898.

Abstract
PURPOSE One quarter of patients will not respond to initial intra-detrusor Botulinum toxin A (BTX) injections for detrusor overactivity. Alternative treatment options include long-term catheterization, sacral neuromodulation, urinary diversion or bladder augmentation. Some of these procedures are invasive. This review explores modifications to BTX delivery that can improve outcome. METHODS A search of Medline, Embase and Cochrane Library to December 2017 was performed according to Preferred Reporting Items for Systematic Review and Metaanalysis (PRISMA) guidelines. Search criteria included, dose escalation, increasing injection site number, trigone injection, switching preparation and alternative methods of BTX delivery. RESULTS Several modifications to BTX delivery may improve response. There is moderate evidence that increasing the dose from 100 U to 200 U results in statistically better symptom control. Trigone-including injections were associated with significantly improved patient-reported symptom scores, as well as superior results in urodynamic outcomes without risking urinary retention and vesico-ureteric reflux. Switching from onabotulinum (OTA) or abobotulinum (ATA) or vice versa may also improve response in over 50% of patients as shown in limited studies. Increasing the number of injection sites is not beneficial. Indeed, decreasing the number of injections to as low as three sites does not result in decreased clinical outcomes. Injection-free delivery is associated with lower efficacy compared to conventional intradetrusor injections. CONCLUSION Before contemplating alternative treatments, practitioners can try to improve on BTX delivery. Firstly, the dose can be increased to 200 U; the trigone included in the injection sites and switching brands may also be helpful.

Abstract
PURPOSE Given that more cancers are being diagnosed earlier and that treatment of cancer is improving, health issues of cancer survivors are becoming more common and apparent. Pelvic radiation therapy for the treatment of gynecological cancers can lead to long-term collateral damage to the bladder, a condition termed radiation cystitis (RC). Late sequelae may take many years to develop and include incontinence and pain as well as hematuria. RC is a rare but potentially life-threatening condition for which there are few management and treatment options. METHODS There are limited data in the literature regarding the effects of radiation on the bladder after gynecological cancer therapy and we hereby review the literature on cancer survivorship issues of pelvic radiation for gynecology literature. RESULTS Treatment options are available for patients with radiation-induced hemorrhagic cystitis. However, most treatments are risky or only effective for a short timeframe and no therapy is currently available to reverse the disease progress. Furthermore, no standardized guidelines exist describing preferred management options. Common therapies include hyperbaric oxygen therapy, clot evacuation, fulguration, intravesical instillation of astringent agents, and surgery. Novel developing strategies include Botulinum Toxin injections and liposomal-tacrolimus instillations. These treatments and strategies are discussed. CONCLUSIONS In this review, we will present current and advanced therapeutic strategies for RC to help cancer survivors deal with long-term bladder health issues.

Abstract
Intradetrusor injection of botulinum toxin A (BTX-A) is an effective option for managing patients with neurogenic detrusor overactivity (NDO) who do not respond to or tolerate oral pharmacologic agents. There is level I evidence that intradetrusor injection of onabotulinumtoxinA for refractory NDO in patients with multiple sclerosis and spinal cord injury is associated with a significantly greater achievement of goals and improved performance in urodynamic studies than placebo. Pilot studies or small case series support BTX-A for NDO in patients with Parkinson's disease and cerebrovascular accident. BTX-A seems to be effective in children with myelomeningocele. However, no adult data exists.

Abstract
Zusammenfassung. OAB (overactive bladder syndrome) ist zwar ein häufiges Leiden, doch wird es oft nicht diagnostiziert und deshalb nicht behandelt. Die Behandlung erfolgt symptomatisch. Im Praxisalltag muss vorgängig eine Basis-(Ausschluss)-Diagnostik durchgeführt werden. Das Führen eines Blasentagebuchs ist sowohl für die Diagnostik als auch für den Verlauf wichtig. Eine urogynäkologische Abklärung mit Urodynamik empfiehlt sich in unklaren Situationen und beim Vorliegen einer gemischten Symptomatik mit Symptomen einer Belastungsinkontinenz oder bei gleichzeitigem Vorliegen einer Blasenentleerungsstörung. Die Therapie erfolgt Schritt für Schritt. Schon einfache Verhaltensänderungen und ein Blasen- und Beckenbodentraining können die Symptomatik deutlich verbessern. Viele Patientinnen profitieren aber zusätzlich von der medikamentösen Therapie. Jahrzehntelang standen dazu alleinig Anticholinergika zur Verfügung. Doch die Langzeitcompliance ist unter diesen Medikamenten gering. Neu erweitern β3-Adrenorezeptor-Agonisten das therapeutische Spektrum: Bei ähnlicher Wirkung unterscheidet sich das Nebenwirkungsprofil unter anderem durch das Fehlen von Mundtrockenheit. Bei therapierefraktärer OAB steht die intravesikale Injektion von Onabotulinumtoxin A als sehr effektive Therapie zur Verfügung. In seltenen Fällen ist auch eine Neuromodulation indiziert.

Abstract
BACKGROUND Several options exist for managing overactive bladder (OAB), including electrical stimulation (ES) with non-implanted devices, conservative treatment and drugs. Electrical stimulation with non-implanted devices aims to inhibit contractions of the detrusor muscle, potentially reducing urinary frequency and urgency. OBJECTIVES To assess the effects of ES with non-implanted electrodes for OAB, with or without urgency urinary incontinence, compared with: placebo or any other active treatment; ES added to another intervention compared with the other intervention alone; different methods of ES compared with each other. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 10 December 2015). We searched the reference lists of relevant articles and contacted specialists in the field. We imposed no language restrictions. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials of ES with non-implanted devices compared with any other treatment for OAB in adults. Eligible trials included adults with OAB with or without urgency urinary incontinence (UUI). Trials whose participants had stress urinary incontinence (SUI) were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, extracted data from eligible trials and assessed risk of bias, using the Cochrane 'Risk of bias' tool. MAIN RESULTS We identified 63 eligible trials (4424 randomised participants). Forty-four trials did not report the primary outcomes of perception of cure or improvement in OAB. The majority of trials were deemed to be at low or unclear risk of selection and attrition bias and unclear risk of performance and detection bias. Lack of clarity with regard to risk of bias was largely due to poor reporting.For perception of improvement in OAB symptoms, moderate-quality evidence indicated that ES was better than pelvic floor muscle training (PFMT) (risk ratio (RR) 1.60, 95% confidence interval (CI) 1.19 to 2.14; n = 195), drug treatment (RR 1.20, 95% 1.04 to 1.38; n = 439). and placebo or sham treatment (RR 2.26, 95% CI 1.85 to 2.77, n = 677) but it was unclear if ES was more effective than placebo/sham for urgency urinary incontinence (UUI) (RR 5.03, 95% CI 0.28 to 89.88; n = 242). Drug treatments included in the trials were oestrogen cream, oxybutynin, propantheline bromide, probanthine, solifenacin succinate, terodiline, tolterodine and trospium chloride.Low- or very low-quality evidence suggested no evidence of a difference in perception of improvement of UUI when ES was compared to PFMT with or without biofeedback.Low- quality evidence indicated that OAB symptoms were more likely to improve with ES than with no active treatment (RR 1.85, 95% CI 1.34 to 2.55; n = 121).Low- quality evidence suggested participants receiving ES plus PFMT, compared to those receiving PFMT only, were more than twice as likely to report improvement in UUI (RR 2.82, 95% CI 1.44 to 5.52; n = 51).There was inconclusive evidence, which was either low- or very low-quality, for OAB-related quality of life when ES was compared to no active treatment, placebo/sham or biofeedback-assisted PFMT, or when ES was added to PFMT compared to PFMT-only. There was very low-quality evidence from a single trial to suggest that ES may be better than PFMT in terms of OAB-related quality of life.There was a lower risk of adverse effects with ES than tolterodine (RR 0.12, 95% CI 0.05 to 0.27; n = 200) (moderate-quality evidence) and oxybutynin (RR 0.11, 95% CI 0.01 to 0.84; n = 79) (low-quality evidence).Due to the very low-quality evidence available, we could not be certain whether there were fewer adverse effects with ES compared to placebo/sham treatment, magnetic stimulation or solifenacin succinate. We were also very uncertain whether adding ES to PFMT or to drug therapy resulted in fewer adverse effects than PFMT or drug therapy alone Nor could we tell if there was any difference in risk of adverse effects between different types of ES.There was insufficient evidence to determine if one type of ES was more effective than another or if the benefits of ES persisted after the active treatment period stopped. AUTHORS' CONCLUSIONS Electrical stimulation shows promise in treating OAB, compared to no active treatment, placebo/sham treatment, PFMT and drug treatment. It is possible that adding ES to other treatments such as PFMT may be beneficial. However, the low quality of the evidence base overall means that we cannot have full confidence in these conclusions until adequately powered trials have been carried out, measuring subjective outcomes and adverse effects.

Abstract
Overactive bladder (OAB) is a condition affecting millions of individuals in the United States. Anticholinergics are the mainstay of treatment. Bladder botulinum toxin injections have shown an improvement in symptoms of OAB equivalent to anticholinergic therapy. Percutaneous tibial nerve stimulation can decrease symptoms of urinary frequency and urge incontinence. Sacral neuromodulation for refractory patients has been approved by the Food and Drug Administration for treatment of OAB, urge incontinence, and urinary retention. Few randomized, head-to-head comparisons of the different available alternatives exist; however, patients now have increasing options to manage their symptoms and improve their quality of life.

Abstract
OBJECTIVES The aim of this study was to characterize the response of the rat bladder neuromuscular system to intramural injection of onabotulinum toxin type A (BoNT/A) over 9 weeks using in vivo cystometry (CMG) and in vitro contractility (IVC). METHODS Chronic bladder catheters were implanted in female Sprague-Dawley rats, and either (1) BoNT/A (10 units in 20 μL saline) or (2) saline (20 μL) was injected in 5 × 4 μL doses throughout the bladder wall. At 1, 3, 6, and 9 weeks after injection, conscious restrained CMG was performed. At each time point, 25% of each group (8 BoNT/A and 4 controls) was euthanized and bladders harvested for IVC. We measured IVC in response to electric field stimulation, carbachol, and potassium chloride. RESULTS In total, 47 animals were included; 31 underwent BoNT/A injection, and 16 received sham (saline). Bladder capacities did not differ significantly between groups for each time point. One week after injection BoNT/A animals exhibited significantly longer bladder contraction durations and lower voiding efficiencies compared with controls. By 3 weeks these values returned to control levels. For BoNT/A animals, contractile response to carbachol stimulation was enhanced at 3 weeks. Otherwise, there were no differences in IVC responses. CONCLUSIONS One week after BoNT/A injection, prolonged bladder contractions are noted in rats. This may reflect supraspinal compensation for denervation by increasing the duration of efferent drive during voiding. After 3 weeks postinjection, we observed no differences in either CMG or IVC responses suggesting either compensatory efferent sprouting, increased gap junction formation, or loss of BoNT/A effect.

Abstract
Objective: The efficacy of intravesical botulinum toxin-A (BTX-A) for the treatment of idiopathic detrusor overactivity (IDO) is well-established and evidence-based. The optimal regime in terms of dose, distribution, depth of injection and number of injections has not been determined and there is still considerable variation throughout clinical practice. We aim to establish the optimum template for bladder injections. Patients and methods: All patients had urodynamically-proven IDO which had failed conservative and medical management. AbobotulinumtoxinA (250 units) was injected into the detrusor and sub-urothelium in one of five injection templates under general anaesthetic. An Overactive Bladder Symptom Score (OABSS) and International Prostate Symptoms Score (IPSS)-Likert quality of life (QoL) score was completed pre-operatively and at six weeks post-operatively. In those who underwent repeat treatments the time to re-commencement of pharmacological therapy was recorded. Results: In total 111 patients received 170 treatments. The average age of patients was 57 (range: 17–86) and the male: female ratio was 0.18:1. Overall there was a mean improvement in the OABSS by −3.7 points±4.29 (standard deviation (SD) ( p<0.01) and an average change in the QoL score of −2.18±2.17 (SD) ( p<0.01) with BTX-A treatment. When analysed by template subgroup there was no statistically significant difference in the magnitude of change for any template over the other four for either the OABSS ( p=0.78) or QoL scores ( p=0.56). Forty-one patients had multiple treatments and had data collected for the duration to treatment failure. The overall average time to treatment failure was 11.2±7.9 months. Subgroup analysis showed that there was no statistically significant ( p=0.783) difference in time to treatment failure for any one of the injection distributions. Conclusion: This study has shown that altering the injection protocol of BTX-A did not affect the clinical outcome in terms of symptoms, QoL or in the time to treatment failure.

OBJECTIVES To determine the effectiveness of: ES with non-implanted electrodes compared with placebo or any other active treatment for OAB; ES added to another intervention compared with the other intervention alone; different methods of ES compared with each other.

We searched the reference lists of relevant articles and contacted specialists in the field. We imposed no language restrictions. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials of ES with non-implanted devices compared with any other treatment for OAB in adults. Eligible trials included adults with OAB with or without urgency urinary incontinence (UUI). Trials whose participants had stress urinary incontinence (SUI) were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently screened search results, extracted data from eligible trials and assessed risk of bias, using the Cochrane Collaboration's 'Risk of bias' tool. MAIN RESULTS We identified 51 eligible trials (3443 randomised participants). Thirty-three trials did not report the primary outcomes of subjective change in OAB symptoms. The majority of trials were deemed to be at low or unclear risk of selection and attrition bias and unclear risk of performance and detection bias. Lack of clarity with regard to risk of bias was largely due to poor reporting.Twenty-three trials (1654 participants) compared ES with no active treatment, placebo or sham treatment. Moderate-quality evidence indicated that OAB symptoms were more likely to improve in people receiving ES than with no active treatment, placebo or sham treatment (relative risk (RR) for no improvement 0.54, 95% confidence interval (CI) 0.47 to 0.63). Moderate-quality evidence indicated that similar numbers of people receiving ES and no active treatment, placebo or sham treatment experienced adverse effects.Eight trials (542 participants) compared ES with conservative treatment. Very low-quality evidence suggested no evidence of a difference between ES and PFMT or PFMT plus biofeedback in OAB symptoms (RR for no improvement 0.79, 95% CI 0.51 to 1.21 and 0.97, 95% CI 0.60 to 1.57 respectively). There was no evidence of a difference between ES and conservative treatment with regard to adverse effects.Sixteen trials (894 participants) compared ES with drug treatment (probanthine, tolterodine, oxybutynin, propantheline bromide, solifenacin succinate, terodiline, trospium chloride, terodiline). Moderate-quality evidence indicated that OAB symptoms were more likely to improve with ES than drug treatment (RR for no improvement 0.66, 95% CI 0.48 to 0.90). Low-quality evidence suggested a greater risk of adverse effects with oxybutynin (RR 1.26, 95% CI 1.07 to 1.49) and with tolterodine (RR 1.51, 95% CI 1.21 to 1.89) than with ES. There was insufficient evidence of a difference between ES and trospium hydrochloride (RR 0.73, 95% CI 0.43 to 1.25).Eight trials (252 participants) compared ES combined with another treatment versus the other treatment alone, two trials (48 participants) compared ES plus conservative treatment with no active treatment, placebo or sham treatment and six trials (361 participants) compared different types of ES. None of these comparisons had sufficient evidence to indicate any differences between the treatment groups in terms of OAB or adverse effects.Moderate-quality evidence suggested that ES improved OAB-related quality of life more than no active treatment, placebo or sham treatment. There was insufficient evidence of any difference between ES and any other treatment with regard to quality of life.There was insufficient evidence to determine if the benefits of ES persisted after the active treatment period stopped. AUTHORS' CONCLUSIONS Electrical stimulation appeared to be more effective than both no treatment and drug treatment for OAB. There was insufficient evidence to determine if ES was more effective than conservative treatment or which type of ES was more effective. This review underlines the need to conduct well-designed trials in this field measuring subjective outcomes and adverse effects.

Intravesical OnabotulinumtoxinA Injection for Overactive Bladder Patients with Frailty, Medical Comorbidities or Prior Lower Urinary Tract Surgery. Toxins (Basel) 2016; 8:91.

Abstract
Overactive bladder (OAB) symptoms increase with age and involve several comorbidities. OnabotulinumtoxinA (BoNT-A) intravesical injection is a treatment choice for patients who are intolerant of or refractory to antimuscarinics. However, the increased risk of urinary tract infection and elevated post-void residual (PVR) volume post-treatment require resolution. Male sex, baseline PVR > 100 mL, and comorbidities are independent risk factors of adverse events (AEs) such as acute urinary retention (AUR). Intravesical BoNT-A injection is safe and effective for OAB patients with frailty, medical comorbidities such as Parkinson's disease (PD), chronic cerebrovascular accidents (CVA), dementia, or diabetes, or a history of prior lower urinary tract surgery (prostate or transvaginal sling surgery). Post-treatment, 60% of frail elderly patients had a PVR volume > 150 mL and 11% had AUR. Although intravesical BoNT-A injection is safe for PD patients, CVA patients had higher strain voiding rates. Diabetic patients were at increased risk of large PVR urine volume and general weakness post-treatment. Treatment results were similar between patients with and without a history of prostate or transvaginal sling surgery. Possible AEs and bladder management strategies should be conveyed to patients before treatment. Careful patient selection is important, and therapeutic safety and efficacy should be carefully balanced.

Comparative assessment of onabotulinumtoxinA and mirabegron for overactive bladder: an indirect treatment comparison. BMJ Open 2016; 6:e009122. [PMID: 26908514 PMCID: PMC4769403 DOI: 10.1136/bmjopen-2015-009122] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2015] [Revised: 01/15/2016] [Accepted: 01/25/2016] [Indexed: 11/22/2022] Open
Abstract
CONTEXT OnabotulinumtoxinA and mirabegron have recently gained marketing authorisation to treat symptoms of overactive bladder (OAB). OBJECTIVE To evaluate the relative efficacy of mirabegron and onabotulinumtoxinA in patients with idiopathic OAB. DESIGN Network meta-analysis. DATA SOURCES A search of 9 electronic databases, review documents, guidelines and websites. METHODS Randomised trials comparing any licensed dose of onabotulinumtoxinA or mirabegron with each other, anticholinergic drugs or placebo were eligible (19 randomised trials were identified). 1 reviewer extracted data from the studies and a second reviewer checked the data. Candidate trials were assessed for similarity and networks were developed for each outcome. Bayesian network meta-analysis was conducted using both fixed-effects and random-effects models. When there were differences in mean baseline values between mirabegron and onabotulinumtoxinA trials they were adjusted for using network meta-regression (NMR). RESULTS No studies directly comparing onabotulinumtoxinA to mirabegron were identified. A network was created for each of the 7 outcomes, with 3-9 studies included in each individual network. The trials included in the networks were broadly similar. Patients in the onabotulinumtoxinA trials had more urinary incontinence and urgency episodes at baseline than patients in the mirabegron trials and these differences were adjusted for using NMR. Both onabotulinumtoxinA and mirabegron were more efficacious than placebo at reducing the frequency of urinary incontinence, urgency, urination and nocturia. OnabotulinumtoxinA was more efficacious than mirabegron (50 and 25 mg) in completely resolving daily episodes of urinary incontinence and urgency and in reducing the frequency of urinary incontinence, urgency and urination. NMR supported the results of the network meta-analysis. CONCLUSIONS In the absence of head-to-head trials comparing onabotulinumtoxinA to mirabegron, this indirect comparison indicates that onabotulinumtoxinA may be superior to mirabegron in improving symptoms of urinary incontinence, urgency and urinary frequency in patients with idiopathic OAB.

Abstract
As diagnosis and treatment of cancer is improving, medical and social issues related to cancer survivorship are becoming more prevalent. Hemorrhagic cystitis (HC), a rare but serious disease that may affect patients after pelvic radiation or systemic chemotherapy, has significant unmet medical needs. Although no definitive treatment is currently available, various interventions are employed for HC. Effects of nonsurgical treatments for HC are of modest success and studies aiming to control radiation-induced bladder symptoms are lacking. In this review, we present current and advanced therapeutic strategies for HC to help cancer survivors deal with long-term urologic health issues.

Abstract
Overactive bladder syndrome is highly prevalent, and increasingly so with aging. It is characterized by the presence of urinary urgency, and can be associated with incontinence, increased voiding frequency, and nocturia. Assessment needs to exclude serious medical disorders that might present with similar symptoms, and a bladder diary is an invaluable part of understanding the presentation. Initial management is conservative, comprising education, bladder training, and advice on fluid intake. Drug therapy options include antimuscarinic medications and beta-3 adrenergic receptor agonists. Persistent overactive bladder syndrome, despite initial therapy, requires a review of the patient’s understanding of conservative management and compliance, and adjustment of medications. For refractory cases, specialist review and urodynamic testing should be considered; this may identify detrusor overactivity or increased filling sensation, and needs to exclude additional factors, such as stress incontinence and voiding dysfunction. Botulinum neurotoxin-A bladder injections can be used in severe overactivity, provided the patient is able and willing to do intermittent self-catheterisation, which is necessary in about 5% of treated patients. Sacral nerve stimulation and tibial nerve stimulation are other approaches. Major reconstructive surgery, such as augmentation cystoplasty, is rarely undertaken in modern practice but remains a possibility in extreme cases.
