Abstract
Background: Neurogenic detrusor overactivity (NDO) is a severe pathological condition characterized by involuntary detrusor contractions leading to urine leakage. This condition is frequent after spinal cord injury (SCI). Gene therapy for NDO requires the development of vectors that express therapeutic transgenes driven by sensory neuron-specific promoters. The aim of this study was to develop and assess tools for the characterization of sensory neuron-specific promoters in dorsal root ganglia (DRG) neurons after transduction with herpes simplex virus type 1 (HSV-1)-based amplicon defective vectors. Methods: The HSV-1 vector genome encoded two independent transcription cassettes: one expressed firefly luciferase (FLuc) driven by different promoters’ candidates (rTRPV1, rASIC3, rCGRP, or hCGRP), and the other expressed a reporter gene driven by an invariable promoter. The strength and selectivity of promoters was assessed in organotypic cultures of explanted adult DRG, or sympathetic and parasympathetic ganglia from control and SCI rats. Results: The rCGRP promoter induced selective expression in the DRG of normal rats. The rTRPV-1 promoter, which did not display selective activity in control rats, induced selective expression in DRG explanted from SCI rats. Conclusions: This study provides a methodology to assess sensory neuron-specific promoters, opening new perspectives for future gene therapy for NDO.

Abstract
The current study assessed the impact of urinary incontinence (UI) on residents, staff, care processes, and quality measures in long-term care (LTC) settings. A 70-question quantitative online survey was sent to directors of nursing (DONs) who had worked for ≥1 year in a ≥100-bed facility (≥80% LTC beds). Of the 62% of residents with UI, 40% were always incontinent, and 81% used incontinence products for UI. Overall, 59% of DONs reported that UI management contributes to certified nursing assistant turnover. Approximately 36% of resident falls occurred while trying to get to the bathroom. LTC quality measures reported as significantly impacted by UI included urinary tract infection and falls with major injury. Only 14% of residents with UI were treated with medication. Most (75%) DONs were unaware of any link between anticholinergic medications and risk of cognitive side effects. These results highlight the need for improved UI treatment, awareness, and management in this population. [Journal of Gerontological Nursing, 48(7), 38-46.].

Abstract
OBJECTIVE Overactive bladder affects 17% of women, and adherence to treatment is notoriously low. The objective of this pilot study is to investigate the efficacy and feasibility of the use of asynchronous telehealth visits for the treatment of women with overactive bladder. METHODS This is a pilot study of women who participated in the asynchronous telehealth program with a new diagnosis of overactive bladder presenting to the Massachusetts General Hospital from January of 2020 to March of 2021. Pre-post differences in Urogenital Distress Inventory score-6, and Incontinence Severity Index Scores were compared with paired t tests as coprimary endpoints. To assess potential mechanisms of association between asynchronous visits and patient-reported outcomes, total fluid intake, caffeinated beverage consumption, urinary frequency, episodes of urinary leakage were also compared as secondary endpoints. RESULTS A total of 23 women participated, with 50 e-visits completed. The first asynchronous visit was completed after a median of 42days (IQR 36, 51.5) from the initial visit. There was a decrease in the Urogenital Distress Inventory-6 score between the first asynchronous visit and the last (29 points, IQR 16, 37 vs 12 points, IQR 12, 25), respectively (P = 0.014). Similar findings were seen with the Incontinence Severity Index questionnaire, from three (IQR 2, 4) to three (IQR 1, 3) after the asynchronous visit (P = 0.002). CONCLUSION We demonstrate the feasibility of asynchronous visits for the treatment of overactive bladder. Although our results suggest efficacy, given the prepost change in overactive bladder-related questionnaire scores following asynchronous visits, the comparative effectiveness of asynchronous visits versus regular care needs to be confirmed in a randomized trial.

Abstract
In everyday practice, urologists often encounter clinical manifestations of overactive bladder (OAB), without of organic or infectious disease. In such cases, OAB may appears in the structure of a somatized (more often depressive) disorder, and therefore an integrated psychosomatic approach to such patient management is becoming increasingly relevant. The relevance of studying the topic is due to the high prevalence of OAB symptoms, its recurrent course, insufficient effectiveness of urological treatment, a significant decrease in the quality of life and working capacity of the socially active part of the adult population. Our clinical observation illustrates the development of symptoms of OAB with massive "pseudo-urological" symptoms within the framework of recurrent somatized depression in a woman of involutional age.

Abstract
PURPOSE The aim of this study was to evaluate the effect of an intervention based on and information, motivation, behavioral skills (IMB) model on urinary incontinence symptoms, impact on daily activities, and incontinence-specific quality of life in men with overactive bladder dysfunction (OAB) and urge incontinence. DESIGN Parallel-group, open-label, randomized-controlled clinical trial. SUBJECTS AND SETTING The sample comprised 60 male patients admitted to the urology clinic of a training and research hospital in Ankara, Turkey. Inclusion criteria were adult men older than 18 years and diagnosed with OAB and urge incontinence. METHODS Data were collected from February 2018 to February 2019. Participants were randomized into 2 equal groups. The intervention group (n = 30) received a structured intervention based on the IMB model, and a control group (n = 30) received standard OAB management. The primary outcome was severity of urge incontinence measured by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Secondary outcomes were mean scores on the Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire-7 (IIQ-7), and Urinary Incontinence Information Rating. All outcome measures were evaluated before and 6 months after the training. RESULTS Following the intervention, mean ICIQ-SF scores were significantly lower in the IMB model group as compared to the control group. Analysis revealed a significant increase in knowledge scores in both groups when baseline scores were compared to postintervention scores (P = .000 for the intervention group and P = .004 for the control group). The intervention group participants also had a higher postintervention scores when compared to control group subjects (P = .000). CONCLUSIONS A structured behavioral intervention based on the IMB model significantly alleviated the severity of bothersome lower urinary tract symptoms in adult males with OAB and urge incontinence when compared to standard care.

Abstract
The Axonics sacral neuromodulation (SNM) system can be used by people with refractory overactive bladder (OAB) to reduce symptoms of urge urinary incontinence and urinary frequency, where conservative treatments have failed or are not suitable. It is the first system for this indication that makes use of a rechargeable battery to prolong the lifespan of the implanted device, with the potential advantage of reducing the frequency of surgical replacement procedures and associated complications. We describe the evidence considered by the UK National Institute of Health and Care Excellence (NICE) in their evaluation of this evidence, supported by Cedar Healthcare Technology Research Centre. Two observational studies provided descriptive data that suggested improvement in control of symptoms after implantation of the Axonics SNM system; however, there was no peer-reviewed evidence that directly compared rechargeable and non-rechargeable SNM systems. In the absence of long-term data, economic modelling relies on the accuracy of battery life estimates. The evidence supports the case for adopting the Axonics SNM system for treating refractory OAB, when conservative treatment or treatment with medicines has not worked. This conclusion is consistent with other relevant NICE guidelines. Use of Axonics SNM technology in the UK National Health Service (NHS) is associated with a potential cost saving of £6025 per person over a 15-year period when compared with an equivalent non-rechargeable SNM system, assuming the claimed battery life estimate (a minimum of 15 years) is accurate. The cost savings are estimated to start around 6 years after implantation.

Abstract
AIMS Percutaneous tibial nerve stimulation (PTNS) is a simple neuromodulation technique to treat an overactive bladder. It is unclear whether the response to PTNS would suggest a similar response to sacral nerve stimulation (SNS), and whether PTNS could be utilized as an alternative test phase for an SNS implant. This study assessed whether PTNS response was a reliable indicator for subsequent SNS trials. METHODS We performed a retrospective review of the hospital databases to collect all patients who had PTNS and who subsequently had an SNS trial in two tertiary hospitals from 2014 to 2020. Response to both interventions was assessed. A 50% reduction in overactive symptoms (frequency-volume charts) was considered a positive response. McNemar's tests using exact binomial probability calculations were used. The statistical significance level was set to 0.05. RESULTS Twenty-three patients who had PTNS subsequently went on to a trial of SNS. All patients except one had previously poor response to PTNS treatment. Eight of them also failed the SNS trial. However, 15 patients (including the PTNS responder) had a successful SNS trial and proceeded with the second-stage battery implantation. The difference in response rates between the PTNS and SNS trial was statistically significant (p < 0.001). CONCLUSIONS Poor response to PTNS does not seem to predict the likelihood of patients responding to SNS. A negative PTNS trial should not preclude a trial of a sacral nerve implant. The predictive factors for good and poor responses will be the subject of a larger study.

Abstract
Urinary incontinence is considered a health problem that both elderly and young people can suffer, most often elderly women. This problem can lead to difficulties in establishing social relationships and dependence, negatively affecting the quality of life of the people who suffer from it. To evaluate and analyze the studies that demonstrate the efficacy of interventions based on the neuromodulation of the posterior tibial nerve as a treatment for the control of urinary incontinence. The search period for articles focused on those published between March 2011 to March 2021, in five databases (Pubmed, Cochrane Library, Scielo, Google Academic and WOS) based on the clinical question, using the keywords derived from the DeCS and MeSH thesauri, combined with the Boolean operators “AND”, “NOT” and “OR”. The search was limited to publications from the last 10 years, in English and Spanish. After applying the selection criteria and evaluating the quality of the methodology, 5.28% (n = 27) of the 511 results were included with filters: 9 systematic reviews, 10 cohorts and 8 randomized controlled trials. After comparing the different articles, it was found that percutaneous stimulation of the tibial nerve is a suitable technique for treating overactive bladder. It is a promising technique in case of pelvic floor dysfunctions and effective for the control of urinary incontinence.

Abstract
A total of 16 detrusor hyperactivity with impaired contractility (DHIC) patients who received 12 weeks remote variable frequency stimulation (VFS) were enrolled at the First Affiliated Hospital of Zhengzhou University from September 2020 to February 2021. The voiding diary, symptom score scales and incidence of complications were completed and recorded at baseline, constant frequency stimulation (CFS) and VFS phases. Compared with the CFS phase, voiding times, urge incontinence times and daily catheterization volume were reduced; average voiding amount and functional bladder capacity increased; and the quality of life score and mental health questionnaire assessment were improved in the VFS phase(all P<0.05). In the end, among all 16 patients, there were 14 whose symptoms had improved, and there were no new complications such as pain or infection at the implantation site, electrode displacement, and electric shock sensation in the stimulation area. VFS-SNM can not only improve the DHIC patients' lower urinary tract symptoms during storage and urination period, but also improve the patients' quality of life and satisfaction of the therapy.

Abstract
OBJECTIVE The aim of the study was to investigate the therapeutic effect of transcutaneous electrical nerve stimulation on neurogenic overactive bladder that is refractory to pharmacotherapy. METHODS This randomized trial recruited 83 participants with neurogenic overactive bladder that were nonresponsive to 3-mo first-line anticholinergic drug treatment. Participants were randomized into treatment and control groups. Transcutaneous electrical nerve stimulation current consisting of biphasic square wave with pulse durations of 150 μs and pulse frequency set at 20 Hz were applied to for 30 mins once a day for 90 days. Stimulation was provided over the lateral aspect of the sacrum bilaterally of the electrodes. Patients in the transcutaneous electrical nerve stimulation group stopped taking the anticholinergic drugs. The control group continued to receive anticholinergic drugs for 90 days. The participants' Overactive Bladder Symptom Score, the Medical Outcomes Study 36-Item Short-Form Health Survey scores, urodynamic values, and voiding diary data were assessed before and after the therapy. RESULTS The transcutaneous electrical nerve stimulation treatment group had significantly decreased Overactive Bladder Symptom scores compared with the control group (P < 0.001); in addition, half of the Medical Outcomes Study 36-Item Short-Form Health Survey scores were significantly improved in the transcutaneous electrical nerve stimulation group (P < 0.05). The patients treated with transcutaneous electrical nerve stimulation improved significantly voiding diary parameters at P < 0.05. Similarly, urodynamic values at P < 0.05 favored the experimental group over the control group. CONCLUSIONS Applying daily transcutaneous electrical nerve stimulation over the sacral region for 90 days to patient with neurogenic overactive bladder improved overactive bladder symptoms of patients whose response to anticholinergic drugs is far inferior.

Abstract
BACKGROUND Overactive bladder (OAB) syndrome is a symptom complex affecting 12-14% of the UK adult female population. Symptoms include urinary urgency, with or without urgency incontinence, increased daytime urinary frequency and nocturia. OAB has a negative impact on women's social, physical, and psychological wellbeing. Initial treatment includes lifestyle modifications, bladder retraining, pelvic floor exercises and pharmacological therapy. However, these measures are unsuccessful in 25-40% of women (refractory OAB). Before considering invasive treatments, such as Botulinum toxin injection or sacral neuromodulation, most guidelines recommend urodynamics to confirm diagnosis of detrusor overactivity (DO). However, urodynamics may fail to show evidence of DO in up to 45% of cases, hence the need to evaluate its effectiveness and cost-effectiveness. FUTURE (Female Urgency, Trial of Urodynamics as Routine Evaluation) aims to test the hypothesis that, in women with refractory OAB, urodynamics and comprehensive clinical assessment is associated with superior patient-reported outcomes following treatment and is more cost-effective, compared to comprehensive clinical assessment only. METHODS FUTURE is a pragmatic, multi-centre, superiority randomised controlled trial. Women aged ≥ 18 years with refractory OAB or urgency predominant mixed urinary incontinence, and who have failed/not tolerated conservative and medical treatment, are considered for trial entry. We aim to recruit 1096 women from approximately 60 secondary/tertiary care hospitals across the UK. All consenting women will complete questionnaires at baseline, 3 months, 6 months and 15 months post-randomisation. The primary outcome is participant-reported success at 15 months post-randomisation measured using the Patient Global Impression of Improvement. The primary economic outcome is incremental cost per quality-adjusted life year gained at 15 months. The secondary outcomes include adverse events, impact on other urinary symptoms and health-related quality of life. Qualitative interviews with participants and clinicians and a health economic evaluation will also be conducted. The statistical analysis of the primary outcome will be by intention-to-treat. Results will be presented as estimates and 95% CIs. DISCUSSION The FUTURE study will inform patients, clinicians and policy makers whether routine urodynamics improves treatment outcomes in women with refractory OAB and whether it is cost-effective.

Abstract
Continuous sacral neuromodulation (SNM) is used to treat overactive bladder, reducing urine leakage and increasing capacity. Conditional SNM applies stimulation in response to changing bladder conditions, and is an opportunity to study neuromodulation effects in various disease states. A key advantage of this approach is saving power consumed by stimulation pulses. This study demonstrated feasibility of automatically applying neuromodulation using a wireless bladder pressure sensor, a real-time control algorithm, and the Medtronic Summit™ RC+S neurostimulation research system. This study tested feasibility of four conditional SNM paradigms over five days in 4 female sheep. Primary outcomes assessed proof of concept of closed-loop system function. While the bladder pressure sensor correlated only weakly to simultaneous catheter-based pressure measurement (correlation 0.26-0.89, median r=0.52), the sensor and algorithm were accurate enough to automatically trigger SNM appropriately. The neurostimulator executed 98.5% of transmitted stimulation commands with a median latency of 72 ms (n=1,206), suggesting that rapid decision-making and control is feasible with this platform. On average, bladder capacity increased for continuous SNM and algorithm-controlled paradigms. Some animals responded more strongly to conditional SNM, suggesting that treatment could be individualized. Future research in conditional SNM may elucidate the physiologic underpinnings of differential response and enable clinical translation.

Abstract
OBJECTIVES Sacral electrical stimulation has been used for more than a century as an alternative therapy for adult urinary syndromes. In the literature, several studies have validated the efficacy of this technique based on clinical and urodynamic criteria. Nevertheless, few studies have shown beneficial results in children with overactive bladder. MATERIAL AND METHODS We performed a systematic review of studies assessing the impact of sacral electroestimulation treatment on overactive bladder in children. The search identified 389 potentially eligible items. Of them, 14 studies published between 2001and 2019 met the study criteria and were selected for systematic review. RESULTS: All of papers included in this review individually demonstrated a high efficiency rate with good shortterm results, as well as safety in its use due to its minimalrate of adverse effects. However, the comparison of the results obtained in all of them was not possible because the high variety and heterogeneity in the different studies. The main limitation is that there is still no standard protocol for the application of this therapy in the pediatric population. CONCLUSION This review revealed the promising benefits of sacral electroneuromodulation in pediatric patients with overactive bladder. However, more studies with strictly meet pediatric overactive bladder diagnosis and management criteria should be done to protocolize and clarify the effectiveness of this therapeutic approach.

Abstract
OBJECTIVES Transcutaneous tibial nerve stimulation (TTNS) is a noninvasive method used in OAB treatment. Purpose of this study is to compare the effectiveness of the TTNS procedure applied once a week and three times a week in women diagnosed with wet type refractory OAB. METHODS A total of 60 patients diagnosed with wet type OAB that was refractory to medical treatment were included in the study. Participants were equally and randomly divided into two groups: TTNS treatment was performed with a duration of 30 minutes for 12 weeks, once a week to Group I and three times a week to Group II. Pretreatment and posttreatment OAB-V8/ICIQ-SF scores and voiding frequencies recorded in the bladder diary were compared between groups. RESULTS Four patients in Group 1 and eight in Group 2 left the study without completing the treatment. TTNS was performed in both groups for 12 weeks. There was a significant decrease in the voiding frequency, OAB-V8, ICIQ-SF scores in both group 1 and group 2 (P < .001). A significant decrease in the OAB-V8 score was observed in the 5th week in Group 1, and in the 3rd week in Group 2. Complete response was observed in 6 patients (23.1%) in Group 1 after 12 weeks of TTNS procedure. In Group 2, 10 patients (45.5%) had a complete response. After the 12-week TTNS procedure, no significant difference was observed between the groups in terms of treatment response. CONCLUSION TTNS can be safely used before invasive treatments in resistant OAB. TTNS procedure three times a week seems more effective than performing it once a week. What's known TTNS is one of the effective alternative treatments in resistant OAB treatment. What's new As the number of sessions is increased in TTNS treatment, the success of the treatment can increase.

Abstract
UNLABELLED INTRODUCTION Neurogenic lower urinary tract dysfunction (NLUTD) refers to altered function of the urinary bladder, bladder outlet, and external urinary sphincter related to a confirmed neurologic disorder. Neurogenic detrusor overactivity (NDO) is a subset of NLUTD that frequently results in incontinence and may be associated with elevated bladder storage and voiding pressures resulting in upper urinary tract damage. MATERIALS AND METHODS This article provides an update on the evaluation and management of patients with NDO. Basic bladder physiology as well as classification of NLUTD, initial urologic evaluation, and management options ranging from the most conservative to surgical interventions will be covered. RESULTS NDO may be managed by conservative, pharmacologic, and surgical methods. Untreated or inadequately managed NDO may result in significant urologic morbidity and mortality, making careful evaluation and lifelong management necessary to optimize quality of life and prevent secondary complications. CONCLUSIONS Patients with NDO should have life-long urologic surveillance and follow up. The extent of regular evaluation and testing should be based on the principal of risk stratification. Treatment for NDO should be considered not only for clinical symptoms such as incontinence, but also aimed at preserving renal function.

Comparison of Pelvic Floor Muscle Training With Connective Tissue Massage to Pelvic Floor Muscle Training Alone in Women With Overactive Bladder: A Randomized Controlled Study. J Manipulative Physiol Ther 2021; 44:295-306. [PMID: 34090550 DOI: 10.1016/j.jmpt.2021.02.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Revised: 05/17/2020] [Accepted: 02/03/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE The purpose of this study was to compare the effects of a 6-week program of pelvic floor muscle training (PFMT) plus connective tissue massage (CTM) to PFMT alone in women with overactive bladder (OAB) symptoms on those symptoms, pelvic floor muscle strength, and quality of life. METHODS Thirty-four participants were randomly divided into PFMT+CTM (n = 17) and PFMT (n = 17) groups. PFMT was applied every day and CTM was applied 3 days a week for 6 weeks. Before treatment, at week 3, and after treatment (week 6), we assessed pelvic floor muscle strength (with a perineometer), bladder symptoms (with a urine diary), OAB symptom severity (with the 8-item Overactive Bladder Questionnaire [OAB-V8]), urgency (with the Patient Perception of Intensity of Urgency Scale [PPIUS]), and quality of life (with King's Health Questionnaire [KHQ]). The Mann-Whitney U test, χ2 test, Friedman test, and Dunn multiple comparison test were used for analysis. RESULTS In both groups, pelvic floor muscle strength increased, whereas OAB symptoms and PPIUS and KHQ scores decreased after treatment (P < .05). Although the OAB-V8, PPIUS, and KHQ scores decreased at week 3, frequency, OAB-V8, and PPIUS scores, in addition to some parameters of the KHQ, decreased after treatment in the PFMT+CTM group compared to the PFMT group (P < .05). CONCLUSION Compared to PFMT alone, PFMT+CTM achieved superior outcomes in reducing OAB symptoms in the early and late periods.

Abstract
OBJECTIVE We evaluated a combination of transcutaneous electrical nerve stimulation (TENS) and solifenacin succinate versus solifenacin alone in the treatment of overactive bladder (OAB). METHODS Ninety-seven female outpatients with OAB were screened for this double-blind randomized controlled study. Eighty-six patients who met our inclusion criteria were divided randomly into two groups. In group A (43 patients), patients received oral solifenacin and "fake" TENS on the foot; in group B (43 patients), patients received oral solifenacin and effective TENS on the foot. Improvements in OAB symptoms were assessed by Overactive Bladder Symptom Score (OABSS), Overactive Bladder Questionnaire (OAB-q), voiding diaries and urodynamic tests. 70 of 86 patients (36 in group A, 34 in group B) completed the 2 months of treatment and 3 months of follow-up. RESULTS Statistically, the maximum bladder volume and OAB symptoms of both groups improved significantly after treatment. The improvement in group B was significantly better than that in group A, as indicated by the maximum bladder volume, OAB-q score and voiding diary. Some mild adverse effects were observed, including dry mouth, stomach upset, constipation, muscle pain and local paresthesia. CONCLUSION The combination of TENS and solifenacin was more effective in improving OAB symptoms than solifenacin alone.

Abstract
BACKGROUND We aim to compare the safety and effectiveness of transcutaneous tibial nerve stimulation (TTNS) versus percutaneous tibial nerve stimulation (PTNS) in treating overactive bladder. METHODS A systematical search on PubMed, Embase, clinicalTrial.gov, and Cochrane Library Central Register of Controlled Trials from January 1, 1999 to November 1, 2020 was performed. The primary outcomes were the changes in a 3-day voiding diary. Quality of life scores were also evaluated. Review Manager 5.3 (Cochrane Collaboration, Oxford, UK) was applied to conduct all statistical analyses. RESULTS A total of 4 trials (2 randomized controlled trials, 1 retrospective study, and 1 before-after study) with 142 patients were eventually enrolled. Compared with PTNS, TTNS had a similar performance in the voiding frequency in 24 hours (mean difference [MD] = -0.65, 95% confidence interval [CI]: -1.35 to 0.05, P = .07), the number of urgency episodes in 24 hours (MD = 0.13, 95% CI: -0.36 to 0.62, P = .60), the number of incontinence episodes in 24 hours (MD = 0.01, 95% CI: -0.13 to 0.14, P = .93), as well as in the nocturia frequency (MD = -0.14, 95% CI: -0.52 to 0.24, P = .47). Moreover, comparable results were observed regarding HRQL scores (P = .23) and incontinence quality of life scores (P = .10) in both groups. The total complication rate in the current study was 2.1% (3/142). No adverse events were identified in the TTNS group. CONCLUSION Current data supported that TTNS is as effective as PTNS for the treatment of overactive bladder, moreover, with no reported adverse events. However, the evidence is low-grade and well-designed prospective studies with a large sample size are warranted to verify our findings.

Abstract
PURPOSE Overactive Bladder (OAB) is a common condition that is known to have a significant impact on Health Related Quality of Life (HRQoL). Whilst all patients will initially benefit from lifestyle modifications and behavioural therapy in the first instance drug therapy remains integral in management pathways. The purpose of this review paper is to reappraise the evidence based approach to the management of OAB in addition to exploring a new treatment algorithm for the escalation of treatment in those patients with refractory symptoms. DESIGN Literature Review RESULTS: Antimuscarinic drugs are currently the most commonly used medication although the introduction of mirabegron, a β3 agonist, has provided an alternative and also allowed combination therapy in those patients who have failed to improve on primary therapy or who have troublesome side effects. For those patients with symptoms of refractory OAB more invasive therapies including OnabotulinumtoxinA, sacral neuromodulation and Percutaneous Tibial Nerve Stimulation (PTNS) may be indicated. CONCLUSION We propose a new, evidence based, treatment algorithm for the management of OAB in patients who remain refractory to first line therapy.
