Abstract
INTRODUCTION Overactive bladder (OAB) and Underactive bladder (UAB) could be associated with metabolic syndrome, affective disorders, sex hormone deficiency, changes in urinary microbiota, functional gastrointestinal disorders, or autonomic nervous system dysfunction. OBJECTIVES The aim of this Think Tank was to provide a guide on how to investigate OAB and/or detrusor underactivity (DU) patients to better clarify the underlying pathophysiology and possibly personalize the treatment. METHODS A compendium of discussion based on the current evidence related to phenotyping patients with OAB or DU investigating metabolic, neurogical, psychological and gastrointestinal aspects with the aim to personalize the treatment. RESULTS AND CONCLUSIONS The article emphasizes the critical significance of adopting a comprehensive yet tailored approach to phenotyping patients with lower urinary tract symptoms, such as OAB and UAB. The intricate interplay between the lower urinary tract and various factors, metabolic, neurological, psychological, and gastrointestinal can define unique LUT profiles, enabling personalized therapies to replace the one-size-fits-all approach.

Intravesical Injection of Botulinum Toxin Type A in Patients with Refractory Overactive Bladder-Results between Young and Elderly Populations, and Factors Associated with Unfavorable Outcomes. Toxins (Basel) 2023; 15:toxins15020095. [PMID: 36828410 PMCID: PMC9967532 DOI: 10.3390/toxins15020095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 01/16/2023] [Accepted: 01/16/2023] [Indexed: 01/20/2023] Open
Abstract
Intravesical botulinum toxin type A (BoNT-A) injection has been recognized as the standard treatment for refractory overactive bladder (OAB). However, its therapeutic efficacy and safety have not been thoroughly reviewed in elderly patients. This study aims to provide treatment outcomes for patients aged ≥75 years, and to identify factors associated with unfavorable outcomes. Patients receiving intradetrusor injections of 100 U onabotulinumtoxinA for refractory OAB between 2011 and 2021 were retrospectively reviewed. Urodynamic parameters, underlying comorbidities, subjective success, and unfavorable outcomes were assessed. A total of 192 patients were included, and 65 of them were classified into the elderly group. For the elderly group, 60.0% experienced subjective dryness, and 84.6% remained subjective success at 6 months after the injections. The prevalence rates of common unfavorable outcomes, including urinary tract infections, large post-void residual urine volume, and urinary retention, were 9.2%, 27.7%, and 12.3%, respectively. Multivariate analysis revealed that female, baseline urodynamic parameters, and diabetes mellitus were associated with unfavorable outcomes in the elderly group. Intravesical BoNT-A injections provide comparable therapeutic efficacy and safety concerns in elderly patients with refractory OAB. A thorough consultation for treatment benefits and possible adverse events is mandatory before the procedure.

The Correlation of Diabetes Mellitus and Urinary Retention From Intravesical OnabotulinumtoxinA Injection for Overactive Bladder. UROGYNECOLOGY (HAGERSTOWN, MD.) 2022; 29:511-519. [PMID: 36730351 DOI: 10.1097/spv.0000000000001297] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 02/03/2023]
Abstract
IMPORTANCE AND OBJECTIVES The objective was to determine whether patients with diabetes mellitus (DM) treated with intravesical onabotulinumtoxinA (BoNT) injection for overactive bladder (OAB) had increased urinary retention requiring clean intermittent catheterization (CIC), as well as the impact of disease duration and severity. We hypothesize that patients with DM will have higher rates of retention after BoNT injection. STUDY DESIGN We performed a retrospective cohort analysis of women in the Kaiser Permanente Southern California Health System who underwent BoNT injection for OAB, excluding women with a history of urinary retention or neurogenic bladder. RESULTS We identified 565 patients, 410 in the control group and 155 in the DM group. No significant difference was found in the rate of CIC (9% in the control group versus 5.8% in the DM group, P = 0.2), voiding dysfunction, and peak postprocedure postvoid residual volume (PVR). Patients with diabetes had a significantly increased rate of postprocedure urinary tract infection (UTI; 27.6% versus 38.1%, P = 0.02). Urinary tract infection was significantly associated with urinary retention (adjusted odds ratio [OR], 2.26; 95% confidence interval [CI], 1.02-4.99; P = 0.045) and peak PVR ≥200 mL (adjusted OR, 2.42; 95% CI, 1.15-5.06; P = 0.019). Diabetic disease duration and severity were not a predictor of urinary retention, elevated PVR, or voiding dysfunction; however, the presence of ≥1 disease-related complication was a predictor of UTI (adjusted OR, 2.81; 95% CI, 1.34-5.91; P = 0.006). CONCLUSIONS Diabetic patients had a similar rate of urinary retention requiring CIC after BoNT injection for OAB compared with nondiabetic patients. Diabetic patients had an increased risk of UTI based on disease severity.

Abstract
Bladder dysfunction, which involves inadequacies of urine storage or emptying, increases with age. Conventional medications may have insufficient efficacy for patients with refractory lower urinary tract symptoms, and their concomitant adverse events (AEs) may be intolerable for the older adult population. For decades, the botulinum toxin type A (BoNT-A) injection has been an option for managing urine frequency, urge incontinence, and voiding dysfunction in the general population refractory to conventional management. This review focuses on studies of BoNT-A application in the management of bladder dysfunction in older adult patients aged ≥ 65 years. In this target population, intravesical BoNT-A injections provide similar efficacy in idiopathic overactive bladder to that in younger adults. Good clinical response has also been demonstrated in older adult patients presenting with storage dysfunction and with various concomitant underlying neurological diseases. However, caution must be taken for the AEs that occur after intravesical BoNT-A injection, including increased post-void residual urine, acute urine retention, and urinary tract infection. Most evidence shows that age is not a major determinant of AEs after adjusting for other factors. In contrast to its application in storage dysfunction, evidence for voiding dysfunction in older adults is scarce. In general, BoNT-A may be a reasonable option for older adult patients with refractory storage dysfunction because of its promising clinical response without significant systemic AEs. Overall, clinicians should be aware of the balance between the therapeutic efficacy of BoNT-A and local AEs in vulnerable members of this population.

[PMID: 34618366 DOI: 10.1002/nau.24809] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 08/04/2021] [Accepted: 08/12/2021] [Indexed: 11/09/2022]
Abstract
BACKGROUND Injecting onabotulinumtoxinA (BoTN-A) into the bladder has been established as an effective treatment of overactive bladder (OAB) and well-tolerated by patients. However, there evidence suggests the efficacy and safety of this treatment may decrease with age due to increased comorbidities and frailty. This study's objective was to establish empirical evidence regarding age-related differences in outcomes related to BoTN-A for the treatment of idiopathic OAB. METHODS MEDLINE, EMBASE, and the Cochrane Central Registry for Controlled Trials were systematically searched. Results were restricted to randomized control trials of BoTN-A bladder injections for the treatment of idiopathic OAB. The resulting articles' abstracts were screened independently by two reviewers. Those passing the screen were reviewed in full. Articles were excluded if participants were <18 years old, diagnosed with neurogenic overactivity, or treated with both oral medications and BoTN-A; if the frequency and severity of OAB symptoms were not specified; or, if symptoms were not stratified by age. RESULTS The initial search resulted in 1572 articles; 166 were reviewed in full. None met all inclusion/exclusion criteria. However, 21 studies met all criteria except age stratification. Authors were contacted to obtain raw data to perform an independent age-based analysis, but sufficient data was not received. CONCLUSION While the initial systematic review did not generate the expected results, it did reveal that age-related outcomes of BoTN-A for the treatment of OAB are significantly under-studied. Given that the prevalence of OAB increases with age, this is an important knowledge gap. Our article explains the rationale for further study in this area.

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
Diabetes mellitus (DM) is an independent risk factor for overactive bladder (OAB). The pathophysiology of DM-associated OAB is multifactorial and time-dependent. Diabetic bladder dysfunction is highly associated with diabetic complications, mainly including diabetic neuropathy and atherosclerosis. Chronic systemic inflammation and bladder urothelial inflammation may contribute to the onset of OAB. Intravesical botulinum toxin A (BoNT-A) injection has proved to be a successful treatment for idiopathic and neurogenic OAB. BoNT-A can inhibit the efferent pathways of the bladder as well as the chronic inflammation and hypersensitivity via the afferent pathways. We conducted a review of the published literature in Pubmed using a combination of two keywords, namely “botulinum toxin A” (BoNT-A) and “overactive bladder”, with or without the additional keywords “detrusor overactivity”, “diabetes mellitus”, “inflammation”, and “urodynamic study”. We also reviewed the experience of our research teams, who have published several studies of the association between DM and OAB. Since limited data support the effectiveness and safety of BoNT-A for treating patients with DM-associated OAB, a comprehensive evaluation of diabetic complications and urodynamic study is needed before treatment. In the future, it is imperative to explore the clinical characteristics and inflammatory biomarkers of diabetes as determining predictors of the treatment efficacy.

Abstract
After decades of clinical and basic science research, the clinical application of botulinum toxin A (Botox) in urology has been extended to neurogenic detrusor overactivity (NDO), idiopathic detrusor overactivity, refractory overactive bladder (OAB), interstitial cystitis/bladder pain syndrome (IC/BPS), lower urinary tract symptoms, benign prostatic hyperplasia, and neurogenic or non-neurogenic lower urinary tract dysfunction in children. Botox selectively disrupts and modulates neurotransmission, suppresses detrusor overactivity, and modulates sensory function, inflammation, and glandular function. In addition to motor effects, Botox has been found to have sensory inhibitory effects and anti-inflammatory effects; therefore, it has been used to treat IC/BPS and OAB. Currently, Botox has been approved for the treatment of NDO and OAB. Recent clinical trials on Botox for the treatment of IC/BPS have reported promising therapeutic effects, including reduced bladder pain. Additionally, the therapeutic duration was found to be longer with repeated Botox injections than with a single injection. However, the use of Botox for IC/BPS has not been approved. This paper reviews the recent advances in intravesical Botox treatment for OAB and IC/BPS.

Abstract
Although evidence shows that urodynamic study may not improve outcomes, it can be used to evaluate men with lower urinary tract symptoms (LUTSs) which have not been adequately delineated and treated. In young men with LUTS not responding to treatment based on clinical examination, or elderly men with LUTS and incontinence, a complete urodynamic evaluation is mandatory to understand the pathophysiology underlying LUTS, such as bladder outlet obstruction (BOO), detrusor overactivity, and detrusor underactivity. Preoperative urodynamic study-proven BOO is a predictor of a successful surgical outcome. An urodynamic study should be performed when patients with LUTS are planning to undergo surgical treatment for benign prostatic obstruction.

Urodynamic prognostic factors for large post-void residual urine volume after intravesical injection of onabotulinumtoxinA for overactive bladder. Sci Rep 2017; 7:43753.

Abstract
The aim of this study was to identify factors predicting large post-void residual (PVR) (defined as ≥200 mL), an important unsolved problem, after an intravesical injection of onabotulinumtoxinA in patients with overactive bladder syndrome. The data showed that 133 of 290 patients had a large PVR after treatment. Multivariate analysis found that the baseline 3-day daytime frequency episodes and voiding efficiency were independent predictors for postoperative large PVR. A receiver operating characteristic (ROC) curve analysis showed the following optimum cut-off values: (1) 3-day daytime frequency episodes = 25, which has a ROC area of 0.72; and (2) voiding efficiency = 89%, which has a ROC area being 0.66. The predicted logit transformation of probability of large PVR, logit(p), for a given 3-day daytime frequency episodes (a) and voiding efficiency (b%) can be denoted by logit(p) = -5.18 + 0.07 × a + 0.04 × b, with a cutoff value of logit(p) = 0.34 and a ROC area of 0.79. The median value of the persistent large PVR interval was 5 months. In conclusion, low 3-day daytime frequency episodes (<25) and low voiding efficiency (<89%) are associated with large PVR. Besides, logit(p) <0.34 can be used to predict large PVR for its higher ROC area.

Abstract
Introduction and hypothesis Intravesical onabotulinumtoxinA (Botox) injections are effective for the treatment of idiopathic overactive bladder (OAB) symptoms. The aim of our study was to assess the predisposing factors for urinary retention in women with OAB after intravesical Botox injection. Methods All participants were women of European descent with idiopathic OAB. OnabotulinumtoxinA (100 U) was administered in 20 intra-detrusor injections. Analysis was performed based on the results of safety assessments made during follow-up (FU) visits on weeks 2, 4 and 12, in 208 women who were treated with Botox injections for refractory OAB and who completed all FU visits. Results Women who required clean intermittent self-catheterisation (CISC) and those with post-void residual (PVR) greater than 200 ml were older in comparison with patients with PVR between 50 and 200 ml. Patients who required CISC were also characterised by higher parity and particularly by a higher number of vaginal deliveries. Other factors such as body mass index or comorbidities did not significantly influence PVR and the risk of CISC. Conclusions Elderly and/or multiparous women are at increased risk of urinary retention after intravesical 100-U Botox injections. The risk of new onset urine retention in our study has completely disappeared 2 weeks after Botox injections. Based on our results of the way in which the PVRs have changed over time, we can conclude that OAB patients should be optimally assessed during the first 2 weeks after Botox injections.

Abstract
OBJECTIVES To investigate urothelial dysfunction, suburothelial inflammation, and muscarinic receptor expression in diabetic patients with overactive bladder (OAB). METHODS A total 19 patients with OAB and diabetes mellitus (DM), 14 OAB patients without DM, and 10 healthy control subjects were enrolled in the study. Immunofluorescence staining of E-cadherin, zonula occludens-1 (ZO-1), tryptase (mast cell activation), and apoptosis tests on the bladder urothelium and suburothelium were performed. Tissue muscarinic receptor M2, M3, and purinergic receptor P2X3 levels were measured by Western blotting. Video urodynamic studies were analyzed in relation to immunofluorescence and western blotting results. RESULTS The mean age of the controls, OAB patients without and with DM were comparable (62.9 ± 6.9, 58.4 ± 21.3, and 68.9 ± 11.3 years, respectively, P = 0.25). E-cadherin and mast cell expression in the bladder urothelium samples of the DM-OAB group and the OAB group without DM differed significantly from those of the control group (all P < 0.05). However, immunofluorescence analyses including E-cadherin, mast cells, apoptotic cell counts, and ZO-1 were comparable between OAB patients with and without DM. In addition, M3 muscarinic protein expression in the bladders of OAB patients with and without DM was significantly higher than that in the control subjects. The video urodynamic parameters did not correlate with the immunofluorescence data, M2 and M3 muscarinic receptor data, or P2X3 protein expression. CONCLUSION Urothelial dysfunction and chronic suburothelial inflammation may contribute to the pathogeneses of OAB. However, DM does not aggravate the severity of urothelial inflammation in OAB patients.

Intravesical OnabotulinumtoxinA Injection for Overactive Bladder Patients with Frailty, Medical Comorbidities or Prior Lower Urinary Tract Surgery. Toxins (Basel) 2016; 8:91. [PMID: 27023603 PMCID: PMC4848618 DOI: 10.3390/toxins8040091] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Revised: 03/16/2016] [Accepted: 03/18/2016] [Indexed: 02/01/2023] Open
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.

Abstract
We investigated the efficacy and safety of intravesical onabotulinumtoxinA injection in patients with detrusor hyperactivity and impaired contractility (DHIC). Twenty-one patients with urodynamically proven DHIC and 21 age-matched patients with overactive bladder (OAB) with urodynamic detrusor overactivity were treated with intravesical injections of 100 U of onabotulinumtoxinA. The overactive bladder symptom score, urgency severity score, patient perception of bladder condition, global response assessment, voiding diary, and procedure-related adverse events (AE) at baseline, two weeks, one, three, and six months after treatment were assessed. The results showed that the subjective symptom scores improved significantly in both groups, and the scores did not differ between the groups. The decrease in urgency episodes and urgency urinary incontinence were noted in OAB patients but not in DHIC patients. Although the incidence of AEs was comparable between the groups, the therapeutic efficacy lasted for a mean of 4.9 ± 4.8 months in DHIC patients and 7.2 ± 3.3 months in OAB patients (p = 0.03). We concluded that the efficacy of intravesical onabotulinumtoxinA injection for DHIC patients was limited and short-term. Nevertheless, AEs did not increase in DHIC. Intravesical onabotulinumtoxinA might not be a good indication in patients with DHIC and high post-voiding residual urine. Physicians should inform patients of the potential benefits and risks of onabotulinumtoxinA injection for treatment of DHIC.

Practical Aspects of Botulinum Toxin-A Treatment in Patients With Overactive Bladder Syndrome. Int Neurourol J 2015; 19:213-9. [PMID: 26739175 PMCID: PMC4703928 DOI: 10.5213/inj.2015.19.4.213] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2015] [Accepted: 11/02/2015] [Indexed: 11/23/2022] Open
Abstract
Intravesical onabotulinumtoxinA (BoNT-A) injection is an effective treatment for overactive bladder syndrome (OAB) that is refractory to antimuscarinics. An injectable dose of 100 U has been suggested to achieve the optimal balance of benefit and safety in patients with OAB. BoNT-A (total volume of 10 mL) was administered as evenly distributed intradetrusor injections (5 U) across 20 sites approximately 1 cm apart (0.5 mL per site) using a flexible or rigid cystoscope. Treatment with BoNT-A was generally well tolerated by most patients, and most treatment-related adverse events were localized to the urinary tract. The prevalence of OAB increases with age, and elderly patients are more vulnerable to complications. The short-term efficacy of intravesical BoNT-A injection for refractory OAB with no treatment-related complications in the elderly population has been documented. Frail elderly patients can experience the same treatment results, such as significantly improved urgent urinary incontinence and quality of life, as young and nonfrail elderly patients with 100-U BoNT-A injections. However, increased risk of larger postvoid residual (PVR) urine and lower long-term success rates were noted in frail elderly patients; around 11% had acute urinary retention, while 60% had PVR urine volume >150 mL after treatment. In addition, intravesical injection of BoNT-A effectively decreased urgency symptoms in elderly patients with OAB and central nervous system lesions. The adverse effects were acceptable, while the long-term effects were comparable to those in patients with OAB without central nervous system lesions. Nonetheless, the possibility of longstanding urinary retention and chronic catheterization in this vulnerable population requires careful evaluation before treatment with intravesical BoNT-A. In conclusion, the current findings indicate that intravesical BoNT-A is an effective and safe treatment for OAB in elderly patients.

Abstract
OBJECTIVES Specify urinary functional impairment associated with diabetic pathology. Propose guidance for screening, monitoring of clinical signs of lower urinary tract (LUTS) and describe the specifics of the urological treatment of patients. METHODS A review of literature using PubMed library was performed using the following keywords alone or in combination: "diabetes mellitus", "diabetic cystopathy", "overactive bladder", "bladder dysfunction", "urodynamics", "nocturia". RESULTS LUTS are more common in the diabetic population with an estimated prevalence between 37 and 70 %, and are probably underevaluated in routine practice. They are heterogeneous and are frequently associated with other diabetic complications. Both storage and voiding symptoms can coexist. Despite a major evaluation in the literature, no recommendation supervises the assessment and management of LUTS in this specific population. An annual screening including medical history, bladder and kidney ultrasound and post-void residual measurement is required in the follow-up of diabetic patients. Specific urologial referral and urodynamic investigations will be performed according to the findings of first-line investigations. The type of bladder dysfunction, the risk of urinary tract infections and dysautonomia should be considered in the specific urological management of these patients. CONCLUSION Diabetes mellitus significantly impacts on the lower urinary tract function. A screening of LUTS is required as well as other complications of diabetes. The management of LUTS must take into consideration the specific risks of the diabetic patient regarding the loss of bladder contractility, the possibility of dysautonomia and infectious complications.

Abstract
Botulinum toxin subtype A (BoNT-A) is a potent neurotoxin that can selectively modulate neurotransmitter release from nerve endings, resulting in muscular paralysis. BoNT-A might also act on sensory nerves, and have an anti-inflammatory effect. In the first urological use of BoNT-A, injection into the urethral sphincters of patients with detrusor-sphincter dyssynergia resulted in a reduction of urethral resistance and improved voiding efficiency. Subsequently, intravesical BoNT-A injections have received regulatory approval for treatment of neurogenic detrusor overactivity owing to spinal cord lesions or multiple sclerosis, and idiopathic overactive bladder in adults. BoNT-A has also been widely used to treat patients with the off-label indications of neurogenic or non-neurogenic voiding dysfunction and male lower urinary tract symptoms owing to BPH and bladder-neck dysfunction. Other indications for which urologists have applied BoNT-A injections include interstitial cystitis/bladder pain syndrome, bladder oversensitivity and chronic pelvic pain syndrome. BoNT-A is currently delivered as an intravesical injection; however, use of liposome encapsulated formulations is also beginning to show some therapeutic potential.
