Efficacy and safety of intradetrusor abobotulinumtoxinA and incobotulinumtoxinA in women with overactive bladder and the value of local anesthesia: a randomized clinical study. Wien Klin Wochenschr 2024:10.1007/s00508-024-02412-7. [PMID: 39179906 DOI: 10.1007/s00508-024-02412-7] [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: 05/06/2024] [Accepted: 07/15/2024] [Indexed: 08/26/2024]
Abstract
BACKGROUND A non-inferiority clinical study evaluated the efficacy and safety of abobotulinumtoxinA vs. incobotulinumtoxinA intradetrusor injections in women with overactive bladder and urge urinary incontinence. Also, the effect of local anesthesia on the pain level of the procedure was assessed. METHODS Patients were randomized to receive 20 intradetrusor injections of either 300 U abobotulinumtoxinA or 100 U incobotulinumtoxinA. They were further randomized to receive either local anesthesia (40 ml 1% lidocaine solution) or placebo before botulinum toxin injection. Before the procedure and 4 months after the procedure each patient reported urinary incontinence episodes, frequency, nocturia, completed the Urogenital Distress Inventory (UDI-6) score, Incontinence Impact Questionnaire (IIQ-7), and Incontinence Quality of Life (I-QOL) questionnaire. Each patient completed a patient satisfaction survey 4 months after the procedure. During the procedure, the patients graded the pain intensity of every injection on a visual analog scale (VAS). The total score of each questionnaire was considered. RESULTS A total of 54 patients with a mean age of 66 ± 13 (SD) years completed the study. Total scores of UDI‑6, IIQ‑7, I‑QOL, patient satisfaction, urinary incontinence episodes, frequency, nocturia and VAS questionnaires did not show differences between the abobotulinumtoxinA (n = 26) or incobotulinumtoxinA (n = 28) group. Urinary retention requiring catheterization was noted in five patients. The VAS and patient satisfaction questionnaire values did not show significant differences between the group receiving bladder instillation with lidocaine solution (n = 28) or the group receiving placebo (n = 26). CONCLUSION In women with overactive bladder and urge urinary incontinence where conservative treatment failed, abobotulinumtoxinA vs. incobotulinumtoxinA intradetrusor injections showed comparable results regarding improved clinical outcome and patient satisfaction. Local anesthesia before the procedure did not reduce the pain level in comparison with the placebo.

Abstract
Neurogenic lower urinary tract dysfunction is caused by various disorders of the central and peripheral nervous system. This can result in several malfunctions of the storage and voiding phase, which are reflected in symptoms such as urgency, urinary incontinence, recurrent urinary tract infections and post-void residual urine. Reduced quality of life, impairment of the upper urinary tract, reduced employment opportunities and worsening of the symptoms of the underlying condition can be the consequences. Therefore, the primary goals of neuro-urology are to protect the upper urinary tract, maintain continence and improve the quality of life of those affected. To achieve these goals, different intravesical drug and electrophysical therapy options are available. These article addresses these intravesical therapy options as well as their indication and relevance in neuro-urology.

Abstract
OnabotulinumtoxinA (BT-A) is used in different medical fields for its beneficial effects. BT-A, a toxin originally produced by the bacterium Clostridium botulinum, is widely known for its ability to temporarily paralyze muscles by blocking the release of acetylcholine, a neurotransmitter involved in muscle contraction. The literature continually reports new hypotheses regarding potential applications that do not consider blockade of acetylcholine release at the neuromuscular junction as a common pathway. In this opinion article, it is our aim to investigate the different pathway targets of BT-A in different medical applications. First of all, the acetylcholine effect of BT-A is used to reduce wrinkles for cosmetic purposes, in the treatment of urological problems, excessive sweating, temporomandibular joint disorders, obesity, migraine, spasticity in neurological diseases, and in various cases of muscle overactivity such as cervical dystonia, blepharospasm, and essential head tremor. In another potential pathway, glutamate A, CGRP, and substance P are targeted for pain inhibition with BT-A application in conditions such as migraine, trigeminal neuralgia, neuropathic pain, and myofascial pain syndrome. On the other hand, as a mechanism different from acetylcholine and pain mediators, BT-A is used in the treatment of hair loss by increasing oxygenation and targeting transforming growth factor-beta 1 cells. In addition, the effect of BT-A on the apoptosis of cancer cells is also known and is being developed. The benefits of BT-A applied in different doses to different regions for different medical purposes are shown in literature studies, and it is also emphasized in those studies that repeating the applications increases the benefits in the long term. The use of BT-A continues to expand as researchers discover new potential therapeutic uses for this versatile toxin.

Abstract
AIM To assess the efficacy of switching to Abobotulinumtoxin A (ATA) intradetrusor injections (IDI) after failure of Onabotulinumtoxin A (OTA) IDI for the treatment of neurogenic detrusor overactivity in patients with spinal cord injury (SCI). MATERIALS AND METHODS A single-centre retrospective chart review study. All SCI patients who started OTA IDI after 2011 and had an ATA IDI switch were included. The primary outcome was the clinical and urodynamic efficacy of the switch to ATA IIDs at the last follow-up. Secondary outcomes were initial efficacy, duration of ATA treatment, and patient outcome including the occurrence of augmentation enterocystoplasty at last follow-up. RESULTS Sixty-two patients were included. Eighteen patients (28.9%) were initially responders to ATA IDI. Nine patients (14.5%) remained responders at last follow-up after a median of 17 months (AE 8.8-29). Thirty-two patients (51.6%) had had or were awaiting augmentation enterocystoplasty with a follow-up time of 18.5 months (IQR 8-27). Eleven patients (17.7%) were on ATA IDI with low efficacy. Seven patients (11.3%) were switched back to OTA and 3 patients (4.8%) changed their voiding pattern. CONCLUSION Switching from OTA to ATA toxin for IDI in the treatment of detrusor overactivity after spinal cord injury have long-term efficacy for a limited number of patients but may delay the need for surgery.

Abstract
CONTEXT Urinary incontinence (UI) is a common condition in elderly men causing a severe worsening of quality of life, and a significant cost for both patients and health systems. OBJECTIVE To report a practical, evidence-based, guideline on definitions, pathophysiology, diagnostic workup, and treatment options for men with different forms of UI. EVIDENCE ACQUISITION A comprehensive literature search, limited to studies representing high levels of evidence and published in the English language, was performed. Databases searched included Medline, EMBASE, and the Cochrane Libraries. A level of evidence and a grade of recommendation were assigned. EVIDENCE SYNTHESIS UI can be classified into stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence. A detailed description of the pathophysiology and diagnostic workup has been reported. Simple clinical interventions, behavioural and physical modifications, and pharmacological treatments comprise the initial management for all kinds of UI. Surgery for SUI includes bulking agents, male sling, and compression devices. Surgery for UUI includes bladder wall injection of botulinum toxin A, sacral nerve stimulation, and cystoplasty/urinary diversion. CONCLUSIONS This 2022 European Association of Urology guideline summary provides updated information on definition, pathophysiology, diagnosis, and treatment of male UI. PATIENT SUMMARY Male urinary incontinence comprises a broad subject area, much of which has been covered for the first time in the literature in a single manuscript. The European Association of Urology Non-neurogenic Male Lower Urinary Tract Symptoms Guideline Panel has released this new guidance, with the aim to provide updated information for urologists to be able to follow diagnostic and therapeutic indications for optimising patient care.

Video-Urodynamic Characteristics and Predictors of Switching from Botulinum Neurotoxin a Injection to Augmentation Enterocystoplasty in Spinal Cord Injury Patients. Toxins (Basel) 2022; 14:toxins14010047. [PMID: 35051024 PMCID: PMC8777902 DOI: 10.3390/toxins14010047] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Revised: 01/05/2022] [Accepted: 01/07/2022] [Indexed: 01/27/2023] Open
Abstract
Botulinum neurotoxin type A (BoNT-A) injection and augmentation enterocystoplasty (AE) are alternative and effective management strategies for neurogenic detrusor overactivity (NDO) refractory to pharmacotherapy. A great majority of patients with spinal cord injury (SCI) may, however, prefer BoNT-A injections to AE, due to the less invasive characteristics. In this study we evaluated the influence of various video-urodynamic study (VUDS) parameters in SCI patients who continuously received repeat BoNT-A detrusor injections or switched to AE to improve their bladder conditions. We compared the changes in the urodynamic parameters before and after each mode of treatment. In this retrospective study, all SCI patients with refractory NDO who had received at least one BoNT-A injection were enrolled. VUDS was performed before and after both BoNT-A injection and AE. All of the urodynamic parameters of the storage and micturition-including the bladder capacity of every sensation, maximal flow rate (Qmax), post-voiding residual volume, detrusor pressure at Qmax, and bladder contractility index-were recorded. A total of 126 patients, including 46 women and 80 men, with a mean age of 41.8 ± 13.1 years, were recruited for this study. All of the patients receiving either BoNT-A injection or AE had a statistically significant increase of bladder capacity at every time-point during filling and a decrease in detrusor pressure at Qmax during voiding. Patients who switched from BoNT-A to AE had greater improvements in their urodynamic parameters when compared with those who continued with BoNT-A injections. Accordingly, SCI patients receiving BoNT-A injections but experiencing few improvements in their urodynamic parameters should consider switching to AE to achieve a better storage function and bladder capacity.

Abstract
Pharmacological management of urinary incontinence (UI) is currently based on antimuscarinic and beta-3-agonist drugs. Botulinum toxin A detrusor injections represent an effective but more invasive alternative. This review covers the latest developments of the currently available drugs and the emerging compounds for the treatment of UI. Evidence shows that new antimuscarinics and beta-3-agonists with improved safety profiles may offer unique options to patients intolerant to currently available drugs. Combination therapy proved to be a non-invasive alternative for patients refractory to first-line monotherapy. Exciting advances are ongoing in the research to improve the efficacy/tolerability profile of botulinum toxin, through innovative routes of administration. Several new agents emerged from preclinical studies, some of which have now entered the clinical phase of development and could represent, in the coming years, a new way for the treatment of UI. Recent evidence on the existence of different overactive bladder phenotypes could be the key to tailored treatment. Rather than discovering new molecules, reaching the ability to identify the right drug for the right patient could be the real gamechanger of the future.

Abstract
Overactive bladder syndrome is a chronic, disabling condition with physical, psychological and social consequences that significantly affects the quality of life of millions of patients worldwide. The economic impact of this disorder is crucial. Overactive bladder syndrome is a little-known condition, with different manifestations from patient to patient, which causes a great deal of frustration to the medical staff involved. The patient requires a clear explanation and the full support of the attending physician. It is extremely important to establish a correct diagnosis and an effective individualized treatment. The collaboration and understanding of these patients are extremely important aspects. Improving the quality of life in these patients is the main purpose in managing this condition. There are several treatment modalities that may be used progressively, with favorable albeit inconsistent results. This condition remains extremely challenging for specialists and, unfortunately, always one of maximum interest.

Frontiers in the Clinical Applications of Botulinum Toxin A as Treatment for Neurogenic Lower Urinary Tract Dysfunction. Int Neurourol J 2021; 24:301-312.

Abstract
Patients with neurogenic lower urinary tract dysfunction (NLUTD) experience urinary incontinence with or without difficult urination, which might promote recurrent urinary tract infection (UTI) and exacerbate upper urinary tract function. Nonetheless, appropriate bladder management has been shown to reduce urological complications and improve quality of life. In addition to pharmacological therapy and surgical intervention, botulinum toxin A (BoNT-A) has been widely utilized in NLUTD. The therapeutic efficacy of detrusor BoNT-A injections for neurogenic detrusor overactivity due to spinal cord injury (SCI), multiple sclerosis, or other central nervous system lesions, such as cerebrovascular accident, Parkinson disease, early dementia, and pediatric NLUTD due to myelomeningocele, has been well established, with repeated BoNT-A injections every 6 to 9 months being necessary to maintain its therapeutic effects. Urethral BoNT-A injection can decrease urethral sphincter resistance and facilitate efficient voiding in patients with NLUTD who wish to preserve self-voiding. Detrusor BoNT-A injection can also decrease the occurrence of autonomic dysreflexia in patients with SCI, even after failed augmentation enterocystoplasty, with additional benefits including reduced UTI episodes and preserved renal function with repeated injections. However, this treatment does have some side effects. Complete informed consent for BoNT-A injection therapy with full disclosure of its potential complications should therefore be obtained before this procedure is undertaken.

Can clinical and urodynamic parameters predict the occurrence of neutralizing antibodies in therapy failure of intradetrusor onabotulinumtoxin A injections in patients with spinal cord injury? BMC Urol 2020; 20:113. [PMID: 32741365 PMCID: PMC7397590 DOI: 10.1186/s12894-020-00683-6] [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] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Accepted: 07/23/2020] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND The aim of the study was to clarify whether clinical and/or urodynamic parameters could be used to infer the probability of neutralizing antibody (NAb) formation as a possible cause of therapy failure (non-response, NR) in patients with neurogenic detrusor overactivity (NDO) due to acquired spinal cord injury/disease (SCI/D) treated with intradetrusor botulinum neurotoxin A (BoNT-A) injections. METHODS A retrospective chart review was performed of all patients with SCI/D who underwent both intradetrusor onabotulinumtoxin A injections and the determination of neutralizing antibodies against BoNT-A between January 1, 2002, and December 31, 2018. NR was defined as urodynamically confirmed persistent or reappearing NDO. RESULTS A total of 2700 BoNT-A injections in 414 patients were ascertained. In 69 patients with primary NR after the first BoNT-A injection (n = 6) or with secondary NR after more than one BoNT-A injection (n = 63), an antibody analysis was performed. Antibody examination showed 36 (52.2%) negative, 5 (7.2%) borderline and 14 (each 20.3%) each of positive and highly positive values. Subgroup analysis indicated a correlation between NAb formation and the duration of BoNT-A therapy (p = 0.015), the mean number of BoNT-A injections (p = 0.011) and the time interval between BoNT-A applications (< 7 months, p = 0.022). Urodynamic data analysis indicate significant differences with cut-off values of MCC (< 225 ml, p = 0.038) and MDP (> 45 cmH2O, p = 0.040). However, in the regression analysis models, the predictive value for the occurrence of NAb was too low (MCC: ROC AUC 0.62, MDP: ROC AUC 0.52) to distinguish with sufficient certainty between NAb-positive and NAb-negative NR patients. CONCLUSIONS Despite significant correlations, clinical and urodynamic parameters are only partially suitable for predicting antibody formation against BoNT-A.

[PMID: 33912405 PMCID: PMC8059473 DOI: 10.4103/tcmj.tcmj_77_20] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 04/24/2020] [Accepted: 04/30/2020] [Indexed: 11/20/2022] Open
Abstract
Chronic spinal cord injury (SCI) can induce neurogenic detrusor overactivity (NDO), leading to urinary incontinence and renal damage due to low bladder compliance and high detrusor pressure during the storage and voiding of urine. In 2011, Botox® (onabotulinumtoxinA, botulinum neurotoxin serotype A [BoNT-A]) was approved by the Food and Drug Administration for the treatment of NDO. Intradetrusor injection of BoNT-A has been shown to have clinical utility for the treatment of urinary incontinence, with consequent improvements in quality of life for patients. In the past 20 years, this treatment has been shown to be an effective treatment for patients with SCI refractory to antimuscarinic medication. The present review focused on publications in MEDLINE/PubMed relating to botulinum toxin to evaluate the treatment outcomes of repeated injection of BoNT-A, the mechanisms of action, results of clinical and urodynamic studies, and adverse effects.

Trigonal-sparing versus trigonal-involved Botox injection for treatment of idiopathic overactive bladder: A randomized clinical trial. Low Urin Tract Symptoms 2020; 13:22-30. [PMID: 32543080 DOI: 10.1111/luts.12321] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 04/11/2020] [Accepted: 04/24/2020] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To evaluate safety and efficacy of trigone-involved Botox injections in comparison with trigone-sparing injections in refractory idiopathic overactive bladder (OAB). MATERIALS AND METHODS One hundred and three patients randomly received a 100-IU intradetrusal injection of Botox either sparing the trigone (52 patients) or involving the trigone (51 patients). Patients were prospectively evaluated at 1, 3, and 6 months. Efficacy was evaluated by 3-day voiding diaries, OAB symptom score (OABSS), and pressure flow study. Any complications were recorded. An ascending cystogram was done at 3 months for detection of vesicoureteral reflux. Urinary tract infection (UTI) was estimated on urine culture basis. Primary outcome was the difference of total OABSS at 3 months. RESULTS The mean age ± SD was 34.3 ± 10 years (range 18-59 years). There was a reduction of episodes of all components of OAB in both groups in comparison with baseline by the end of the study but without significant difference between both groups. The trigonal-sparing group had less score of frequency compared with the trigonal-involved group throughout the study period (P < .05). There was no difference in OABSS at 3 months (1.5 ± 0.4 vs 1.6 ± 0.3, P .875). Two patients in the trigonal-involved group out of 51 (3.9%) were in need of clean intermittent catheterization because of voiding difficulty and a postvoid residual > 200 mL. There was a higher rate of UTI in the trigonal-involved group ranging from 5.6% up to 11.7% at each follow-up visit. No patient had reflux. CONCLUSION Trigone injections are not superior to trigone-sparing injections. On the contrary, the incidence of UTI and voiding difficulty were higher. The concept of reflux induced by trigonal injection has not been proven.

Abstract
INTRODUCTION We aimed to assess safety and efficacy of incobotulinumtoxinA for the treatment of neurogenic detrusor overactivity (NDO). METHODS We identified patients with NDO confirmed on urodynamics (UDS) and reported urgency incontinence (UI) in those who received intravesical incobotulinumtoxin A injection for neurogenic bladder between November 2013 and May 2017. Parameters studied were daytime frequency, daily incontinence episodes, daily pad use, clean intermittent catheterization (CIC) volumes, symptom scores (UDI6, IIQ7, PGII), and complications. RESULTS We examined 17 male patients who met inclusion criteria and underwent incobotulinumtoxinA injection. Mean age was 61.2±15.4 years. Fourteen patients (82%) were taking oral antimuscarinics prior to the incobotulinumtoxin A injection. There were improvements in the following parameters: average daily pads (4.5 to 3.3, p=0.465), daily urinary frequency (9.4 to 4.6, p=0.048), daily incontinent episodes (2.5 to 0.4, p=0.033), CIC volumes (400 to 550 mL, p=0.356), hours in between CIC (3.6 to 5.2, p=0.127), and the validated questionnaires UDI6 (30.6 to 7.4, p=0.543) and IIQ7 (52.4 to 6.8, p=0.029). There were no documented symptomatic urinary tract infections (UTIs) within 30 days of injection or reports of de novo urinary retention. Nine of 17 patients (53%) reported being dry at their first postoperative visit. CONCLUSIONS In this preliminary pilot study of a small cohort of males with NDO and UI, significant improvements were seen following incobotulinumtoxinA injection in daily frequency, incontinence episodes, hours in between CIC, and quality of life. Larger-scale and long-term studies are required to confirm these results, but initial findings are promising for wider use of this formulation.

Abstract
Botulinum toxin A (BTX-A) is a powerful neurotoxin with long-lasting activity that blocks muscle contractions. In addition to effects on neuromuscular junctions, BTX-A also plays a role in sensory feedback loops, suggesting the potentiality for pain relief. Although the only approved indications for BTX-A in the bladder are neurogenic detrusor overactivity and refractory overactive bladder, BTX-A injections to treat bladder pain refractory to conventional therapies are also recommended. The mechanism of BTX-A activity in bladder pain is complex, with several hypotheses proposed in recent studies. Here we comprehensively reviewed properties of BTX-A in peripheral afferent and efferent nerves, the inhibition of nociceptive neurotransmitter release, the reduction of stretch-related visceral pain, and its anti-inflammatory effects on the bladder urothelium. Studies have also revealed possible effects of BTX-A in the human brain. However, further basic and clinical studies are warranted to provide solid evidence-based support in using BTX-A to treat bladder pain.

The Therapeutic Effects and Pathophysiology of Botulinum Toxin A on Voiding Dysfunction Due to Urethral Sphincter Dysfunction. Toxins (Basel) 2019; 11:toxins11120728. [PMID: 31847090 PMCID: PMC6950422 DOI: 10.3390/toxins11120728] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 12/10/2019] [Accepted: 12/11/2019] [Indexed: 12/01/2022] Open
Abstract
Neurogenic and non-neurogenic urethral sphincter dysfunction are common causes of voiding dysfunction. Injections of botulinum toxin A (BoNT-A) into the urethral sphincter have been used to treat urethral sphincter dysfunction (USD) refractory to conventional treatment. Since its first use for patients with detrusor sphincter dyssynergia in 1988, BoNT-A has been applied to various causes of USD, including dysfunctional voiding, Fowler’s syndrome, and poor relaxation of the external urethral sphincter. BoNT-A is believed to decrease urethral resistance via paralysis of the striated sphincter muscle through inhibition of acetylcholine release in the neuromuscular junction. Recovery of detrusor function in patients with detrusor underactivity combined with a hyperactive sphincter also suggested the potential neuromodulation effect of sphincteric BoNT-A injection. A large proportion of patients with different causes of USD report significant improvement in voiding after sphincteric BoNT-A injections. However, patient satisfaction might not increase with an improvement in the symptoms because of concomitant side effects including exacerbated incontinence, urinary urgency, and over-expectation. Nonetheless, in terms of efficacy and safety, BoNT-A is still a reasonable option for refractory voiding function. To date, studies focusing on urethral sphincter BoNT-A injections have been limited to the heterogeneous etiologies of USD. Further well-designed studies are thus needed.

Abstract
Special birth defects and neurological diseases can cause neurogenic detrusor overactivity (NDO). First-line pharmacotherapy is the antimuscarinic therapy, which can be limited by side effects or non-effectiveness. Therefore, pharmacological treatment of NDO in children includes off-label use of intravesical injections of botulinum toxin type A (BTA). In this review article, various clinical studies in which BTA was used for the treatment of NDO of different etiologies in children are discussed, including studies about children with acquired NDO. An electronic literature search was performed using PubMed, and studies published prior to March 2019 are reported. BTA injections are a clinically and urodynamically effective and safe treatment for NDO in children. The treatment is also important in protecting the upper urinary tract from damage and improving concomitant bowel dysfunctions. Fibrotic, acontractile bladders with poor bladder compliance and/or a very small initial bladder capacity and/or the presence of an open bladder neck all contributed to poor responses. A combined injection into the detrusor and external urethral sphincter may improve the clinical outcome in the detrusor-sphincter dyssynergia. New application methods are promising, such as the electromotive drug administration, to avoid general anesthesia. Furthermore, the minimal clinically effective dosage, inclusion criteria, and prognostic factors remain to be established.

Can Botulinum Toxin A Still Have a Role in Treatment of Lower Urinary Tract Symptoms/Benign Prostatic Hyperplasia Through Inhibition of Chronic Prostatic Inflammation? Toxins (Basel) 2019; 11:toxins11090547. [PMID: 31546892 PMCID: PMC6784075 DOI: 10.3390/toxins11090547] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Revised: 09/12/2019] [Accepted: 09/17/2019] [Indexed: 11/16/2022] Open
Abstract
Patients with benign prostatic hyperplasia (BPH) can exhibit various lower urinary tract symptoms (LUTS) owing to bladder outlet obstruction (BOO), prostatic inflammation, and bladder response to BOO. The pathogenesis of BPH involves an imbalance of internal hormones and chronic prostatic inflammation, possibly triggered by prostatic infection, autoimmune responses, neurogenic inflammation, oxidative stress, and autonomic dysfunction. Botulinum toxin A (BoNT-A) is well recognized for its ability to block acetylcholine release at the neuromuscular junction by cleaving synaptosomal-associated proteins. Although current large clinical trials have shown no clinical benefits of BoNT-A for the management of LUTS due to BPH, BoNT-A has demonstrated beneficial effects in certain subsets of BPH patients with LUTS, especially in males with concomitant chronic prostatitis/chronic pelvic pain syndrome and smaller prostate. We conducted a review of published literature in Pubmed, using Botulinum toxin, BPH, BOO, inflammation, LUTS, and prostatitis as the key words. This article reviewed the mechanisms of BPH pathogenesis and anti-inflammatory effects of BoNT-A. The results suggested that to achieve effectiveness, the treatment of BPH with BoNT-A should be tailored according to more detailed clinical information and reliable biomarkers.

Abstract
PURPOSE To evaluate the efficacy and safety of re-treatment with anticholinergics on refractory idiopathic overactive bladder (OAB) previously treated with intravesical botulinum neurotoxin type A (BTX-A) injections. METHODS One hundred patients were initially managed by intravesical injections of 100 IU of BTX-A. After the effects of BTX-A faded, patients were randomized into 2 groups: group A patients received solifenacin (10 mg) for 12 weeks (study group), while group B patients received placebo treatment for 12 weeks (control group), then subsequently received solifenacin (10 mg) for another 6 weeks. All patients underwent preoperative urodynamic testing. Patients were asked to complete the validated overactive bladder symptoms score (OABSS) and incontinence quality of life (I-QoL) instruments after the effects of intravesical BTX-A faded and at 12 weeks of follow-up. Univariate and multivariate analyses of the factors affecting treatment response were conducted. RESULTS At 12 weeks of follow-up, in group A, all OABSS items, including the total score, had improved significantly (P<0.0001). Group A had lower frequency and amplitude of detrusor overactivity and detrusor leak point pressure (P<0.0001, P=0.03, and P=0.01, respectively). Cystometric capacity also increased significantly (P=0.007), as did all I-QoL parameters. In a comparison of patients with failed treatment and patients with successful treatment, female sex, repeated intravesical BTX-A injections, and increased bladder capacity were statistically significant (P=0.001, P=0.0001, and P=0.002, respectively). Repeated intravesical BTX-A injections and increased bladder capacity were independent factors predicting treatment success. CONCLUSION In patients with refractory idiopathic OAB, reuse of anticholinergics could be an effective treatment option in patients after the effects of BTX-A fade. Repeated intravesical BTX-A injections and increased cystometric capacity could affect treatment response.

Abstract
INTRODUCTION Our aim was to determine the factors predicting the outcome of intraprostatic injection of Botulinum Toxin-A (BTX-A) in the treatment of benign prostatic hyperplasia (BPH)-induced lower urinary tract symptoms (LUTS) and to evaluate its efficacy and safety. METHODS Between September 2016 and May 2018, 45 Egyptian patients, with BPH-induced LUTS were included; the indication was a failure of medical treatment, unfit, or refusing surgical intervention. Measurements of prostate size by TRUS, total PSA level before and 12 weeks after injection. IPSS, uroflow, and postvoiding residual urine (PVR) were measured before injection, 2, 4, 8 and 12 weeks postinjection. 100 U BTX-A vial was diluted with 10 mL of saline then injected into the transition zone at base and midzone of the prostate by TRUS. RESULTS The mean patients' age was 64.4 ± 6.6 years. Mean baseline IPSS 24.06 decreased to 18.75 at 2 weeks and progressively decreased to 16.37 at 12 weeks (P < 0.001), Q max of 9.08 mL/s. increased to 10.44 at 2 weeks and 11.44 at 12 weeks (P < 0.001), mean prostate volume was 67.44cc; decreased to 66.06cc (P < 0.001) at 12 weeks and mean residual urine was 82.62 mL and decreased to 57.66 mL at 12 weeks. DISCUSSION Intraprostatic injection of BTX-A as modality treatment of LUTS/BPH significantly improve IPSS, Q max , PVR, and decrease prostate volume. We can suspect better results with this line of treatment in patients with IPSS ≤ 22 and Q max ≤ 10 mL/min and prostate volume ≤ 56.5cc.

Abstract
Objective: To evaluate the efficacy and safety of botulinum toxin A (BoNT-A) instillation in the bladder under the effect of low-energy shockwaves (LESWs) for the treatment of refractory idiopathic overactive bladder (OAB). Patients and methods: A preliminary clinical study was conducted, including 15 patients with refractory OAB, between September 2016 and July 2017. Intravesical instillation of 100 IU of BoNT-A was done followed by LESWs (3000 shocks over 10 min) exposure to the supra-pubic area. Patients were followed-up by urine analysis, urine culture, post-void residual urine volume (PVR), and Overactive Bladder Symptom Score (OABSS) at 1, 2 and 3 months. Results: There were statistically significant improvements in all OABSS domains and the total score after 1 and 2 months of treatment (P < 0.05). Whereas, only the nocturia domain remained significantly improved after 3 months (P = 0.02). There was no significant increase in PVR throughout the study period (P > 0.05) and none of the patients required clean intermittent catheterisation. Two, two and three patients developed urinary tract infections after 1, 2 and 3 months, respectively. Conclusion: Intravesical instillation of BoNT-A and LESWs is safe and effective method for the treatment of refractory OAB with a durable response for 2 months. Abbreviations: BoNT-A: botulinum toxin A; CIC: clean intermittent catheterisation; DO: detrusor overactivity; LESWs: low-energy shockwaves; OAB: overactive bladder; OABSS: Overactive Bladder Symptom Score; Qmax: maximum urinary flow rate; QoL: quality of life; UUI: urgency urinary incontinence.

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.

Abstract
AIMS To compare 300 U versus 500 U of abobotulinumtoxinA (ABO) intravesical injections for the treatment of idiopathic overactive bladder (OAB) refractory to first and second-line treatments. METHODS A prospective, randomized, single blind study was performed in female patients with symptoms of OAB, who had failed conservative treatment. Patients were treated with 300 or 500 U of ABO injected into 30 sites, avoiding the trigone. All treatments were evaluated by voiding diary, ICIQ-OAB questionnaire, urodynamic test, visual analogue scale (VAS) for treatment satisfaction and patient global impression of improvement (PGI-I). The primary outcome was change in maximum cistometric capacity (MCC). Secondary outcome included changes in urgency, complete continence, subjective success (VAS and PGI-I), and adverse events (urinary retention, UTI, and CIC). RESULTS Twenty-one patients were included. MCC has increased from 185.0 to 270.9 mL (300 U) and from 240.8 to 311.7 mL (500 U), comparing the baseline with 12 weeks, without statistical difference between the groups (P = 0.270). At 12 weeks, 91% of patients were dry in both groups. At 24 weeks, episodes of incontinence had returned in 50% (300 U) and 0% (500 U) (P = 0.013). Patients were better or much better (PGI-I) in70% (300 U) and 88.9% (500 U) at 12 w; and 50% (300 U) and 100% (500 U), at 24 w (P = 0.027). The peak of PVR was at 4 w, being 71.7 mL (300 U) and 96.5 mL (500 U). General UTI incidence was 35.7%. One patient (500 U) required CIC for 2 weeks. CONCLUSIONS Intravesical ABO injection at 500 U improves symptoms and quality of life for longer period of time than 300 U for idiopathic OAB.

Abstract
Bladder diverticuli identified following Botox treatment of neurogenic bladder. Magnetic resonance imaging is useful to detect bladder diverticuli following Botox injections. Magnetic resonance imaging following Botox treatment of neurogenic bladder may be helpful.
Urinary incontinence due to neurogenic detrusor overactivity is common in patients with disorders of lower motor neurons controlling the bladder. Multiple sclerosis is a major cause of neurogenic detrusor overactivity, which negatively impacts quality of life. Bladder wall injection of onabotulinum toxin A can diminish spontaneous bladder contraction, urinary urgency, and urge incontinence. Herein we report a 61-year-old woman with multiple sclerosis and autosomal dominant polycystic kidney disease with bladder trabeculation developing after repeated injections of onabotulinum toxin A.

Abstract
INTRODUCTION Overactive bladder is a common condition that can have a negative impact on quality of life. Botulinum Toxin A is a third line treatment for overactive bladder following conservative measures and anticholinergic medication. At present, OnabotulinumtoxinA is the only preparation licensed for this indication. More recently, trials have been undertaken to compare the efficacy of this to AbobotulinumtoxinA. Areas covered: This article aims to provide an overview of AbobotulinumtoxinA, which is currently not yet licensed for overactive bladder or neurogenic detrusor overactivity. It will detail the pharmacokinetics and dynamics, assess the available clinical trial data and make comparisons with current clinical practice. A systematic literature search was completed, using ovid Medline and Embase, with the aim to review all data concerning the administration of AbobotulinumtoxinA for the treatment of overactive bladder. Expert opinion: Currently, there are a lack of data on the use of AbobotulinumtoxinA for overactive bladder or neurogenic detrusor overactivity. Current evidence concentrates on its use in neurogenic detrusor overactivity, and there are data to show it may be as efficacious as OnabotulinumtoxinA. However, there is a lack of homogenous data to compare the two products and therefore we are unable to recommend this currently.

Abstract
OBJECTIVE To assess the safety and efficacy of intradetrusor onabotulinum toxin A injections for the treatment of overactive bladder (OAB) in patients with Parkinson's disease (PD). METHODS All PD patients who underwent intradetrusor injections of onabotulinum toxin A (BoNT-A) for storage symptoms between 2010 and 2017 were included in a retrospective study. A 100 U dose of BoNT-A (Botox®, Allergan Irvine, CA) was used for the first injection in all patients. The primary endpoint was clinical success defined as any subjective improvement in OAB symptoms self-assessed by the patients 4 weeks after the injections. RESULTS Out of 24 patients analyzed, 19 reported improvement of their OAB symptoms 4 weeks after the first injection (79.2%) with complete resolution of urgency urinary incontinence in seven patients (29.1%; P < 0.001). The average post-void residual (PVR) increased significantly after the first injection from 17.6 to 125.3 mL (P < 0.001). Three of the patients had to start clean intermittent catheterization (CIC) after the first injection (12.5%). Out of 49 injections in total, only five caused incomplete bladder emptying requiring the use of CIC (10.2%). Higher pre-injection PVR was significantly associated with both a lower chance of symptomatic improvement (P = 0.04) and a higher risk of incomplete bladder emptying with institution of CIC (P = 0.047). CONCLUSION Intradetrusor injections of BoNT-A 100 U appeared as a safe and effective option in PD patients with OAB symptoms and a low PVR before the injection. Higher preoperative PVR was the strongest predictor of both treatment failure and postoperative urinary retention requiring CIC.

Early experimental results of using a novel delivery carrier, hyaluronan-phosphatidylethanolamine (HA-PE), which may allow simple bladder instillation of botulinum toxin A as effectively as direct detrusor muscle injection. J Pediatr Urol 2018; 14:172.e1-172.e6.

Abstract
INTRODUCTION Botulinum toxin A (BTX-A) is a neurotoxin that inhibits acetylcholine release by cleaving cytosolic synaptosome-associated protein 25 (SNAP-25) and results in bladder relaxation. A BTX-A intravesical injection has been established as an effective option for treating detrusor overactivity. STUDY DESIGN Sixty female Sprague Dawley rats were equally divided into control and experimental groups. Control Groups 1 to 3 received: BTX-A 10 units + saline instillation; hyaluronan-phosphatidylethanolamine (HA-PE) 0.5 g + saline instillation; and BTX-A 5 Uintra-detrusor injections, respectively. Treatment Groups 4 to 6 received: Alexa®594-labeled BTX-A 10 U + HA-PE 0.5 g + saline instillation; BTX-A 5 U + HA-PE 0.2-0.5 g instilled for 60 min; and BTX-A 10 U + HA-PE 0.2-0.5 g instilled for 30 min, respectively. All procedures were performed under isoflurane general anesthesia. The primary outcome of this study was the degree of SNAP-25 staining in control and experimental groups compared to Group 3 (detrusor muscle injection). Urodynamic studies were performed at baseline and at day 14 after 1% acetic acid (AA) instillation, to evaluate the maximum pressure during filling (MP) and inter-contraction intervals (ICI). Group 4 rats were examined for Alexa®594 fluorescence to demonstrate physical translocation of BTX-A-HA-PE complex. Standard histology was performed to assess the effect of HA-PE on bladder mucosa and detrusor muscle. RESULTS Group 3 showed the least SNAP-25 staining (7.3 ± 5.0%) compared with all groups except Group 5A (12.4 ± 12.27%, P = 1.0). Group 6A, which had high HA-PE dose but a shorter instillation time, showed fairly extensive SNAP-25 staining (22.9 ± 10%). Confocal microscopy of Group 4 confirmed the presence of Alexa®594 fluorescence across the urothelium. Urodynamic parameters were not significantly different at baseline (P = 1.0). After acetic acid instillation, Group 5A showed minimal change in ICI, which was comparable to ICI in Group 3 rats. DISCUSSION SNAP-25 staining in Group 5A was comparable to Group 3, suggesting that adequate HA-PE and instillation time allows the efficacy of this carrier mechanism to be comparable to standard intra-detrusor injections. All other groups showed significantly higher SNAP-25 staining compared to Group 3. A dose response effect was demonstrated; higher dose of HA-PE (Group 5A vs Group 5B) and longer instillation time (Group 5 vs Group 6) led to lower SNAP-25 staining. CONCLUSION This novel method of BTX-A delivery to the bladder using a carrier (HA-PE) is promising and requires further investigation. Using a larger animal model, identifying an optimal dose of HA-PE and instillation time, and reproducing the current results are further required to validate this carrier.

Abstract
AIMS OnabotulinumtoxinA (onaBNTa) for treating neurogenic detrusor overactivity (NDO) is widely used after its regulatory approval in adults. Although the administration of onaBNTa is still considered off-label in children, data have already been reported on its efficacy and safety. Nowadays, there is a lack of standardized protocols for treatment of NDO with onaBNTa in adolescent patients in their transition from the childhood to the adult age. With the aim to address this issue a consensus panel was obtained. METHODS A panel of leading urologists and urogynaecologists skilled in functional urology, neuro-urology, urogynaecology, and pediatric urology participated in a consensus-forming project using a Delphi method to reach national consensus on NDO-onaBNTa treatment in adolescence transitional care. RESULTS In total, 11 experts participated. All panelists participated in the four phases of the consensus process. Consensus was reached if ≥70% of the experts agreed on recommendations. To facilitate a common understanding among all experts, a face-to-face consensus meeting was held in Rome in march 2015 and then with a follow-up teleconference in march 2017. By the end of the Delphi process, formal consensus was achieved for 100% of the items and an algorithm was then developed. CONCLUSIONS This manuscript represents the first report on the onaBNTa in adolescents. Young adults should be treated as a distinct sub-population in policy, planning, programming, and research, as strongly sustained by national public health care. This consensus and the algorithm could support multidisciplinary communication, reduce the extent of variations in clinical practice and optimize clinical decision making.

Abstract
OBJECTIVE The aim of this study was to test the addition of methylene blue (MB) to onabotulinum toxin A (BTX-A) solution in overactive bladder (OAB) treatment, as a means of facilitating observation of the injection site and assessing the distribution of the drug under the bladder mucosa during injection. Pharmacological interactions between BTX-A and MB were also evaluated. MATERIALS AND METHODS The study was conducted between December 2014 and April 2016 on 30 patients: six males and 24 females (median age 57.7, range 23-80 years) diagnosed with OAB, who qualified for intravesical BTX-A injection. Each received 100 IU of BTX-A (Botox®; Allergan), dissolved in 9.5 ml of 0.9% NaCl with the addition of 0.5 ml of MB. Cystoscopy with submucosal injection of the solution was performed systematically, including the bladder triangle. For pharmacological evaluation, quantitative determination of MB was performed on a capillary electrophoresis system with diode array detection. RESULTS In the course of 600 injections, the addition of MB facilitated the observation of the procedure; the exact distribution of the solution could not be observed in only 43 injections in seven patients. The range of distribution of the drug varied from 1 to 2.5 cm. Pharmacological evaluation based on visual observations and experiments showed that pharmaceutical interactions do not occur between MB and this commercially available formulation of BTX-A. CONCLUSIONS Applying a coloured solution of BTX-A significantly facilitates observation of the procedure and assessment of drug distribution. There are no pharmaceutical interactions between MB and BTX-A.

Abstract
AIMS To assess the outcomes of switching to a different brand of botulinum toxin A (BTA, from Botox® to Dysport®) in case of failure of intradetrusor injections (IDI) of Botox® in the treatment of neurogenic detrusor overactivity (NDO). METHODS The charts of all patients who underwent a switch to IDI of Dysport® after failure of an IDI of Botox® at six departments of neurourology were retrospectively reviewed. The main outcomes of interest were the bladder diary data and four urodynamic parameters: maximum cystometric capacity (MCC), maximum detrusor pressure (PDET max), and volume at first uninhibited detrusor contraction (UDC). RESULTS Fifty-seven patients were included. After the first injection of Dysport®, no adverse events were reported. A significant decrease in number of urinary incontinence episodes per day was observed in 52.63% of patients (P < 0.001) and all patients experienced a reduction in PDET Max (-8.1 cmH20 on average; P = 0.003). MCC significantly increased by a mean of 41.2 (P = 0.02). The proportion of patients with no UDC increased significantly at week 6 after ATA injections (from 15.79% to 43.9%; P = 0.0002). Hence, 32 patients draw clinical and/or urodynamic benefits from the botulinum toxin switch from (56.14%). After a median follow up of 21 months, 87% of responders to BTA switch were still treated successfully with BTA. CONCLUSION Most patients refractory to Botox® (56.14%) draw benefits from the switch to Dysport®.

Abstract
The use of botulinum toxin A (BoNT-A) has expanded across a range of lower urinary tract conditions. This review provides an overview of the current indications for BoNT-A in the lower urinary tract and critically evaluates the published evidence within each area. The classic application of BoNT-A has been in the management of refractory neurogenic detrusor overactivity (NDO) and overactive bladder (OAB). There is a large volume of high-quality evidence, including numerous randomized placebo-controlled trials, which demonstrate the efficacy of BoNT-A over a long follow-up period. The culmination of this robust evidence-base has led to onabotulinumtoxin A (onaBoNT-A) receiving regulatory approval as a second-line treatment for NDO at a dose of 200 U and OAB at dose of 100 U. Other applications for BoNT-A are used on an off-license basis and include interstitial cystitis/bladder pain syndrome (IC/BPS), benign prostatic hyperplasia (BPH), and detrusor sphincter dyssynergia (DSD). These applications are associated with a less mature evidence-base although the literature is rapidly evolving. At present, the results for painful bladder syndrome (PBS) are promising and BoNT-A injections are recommended as a fourth line option in recent international guidelines, although larger randomized study with longer follow-up are required to confirm the initial findings. As a treatment for DSD, BoNT-A injections have shown potential but only in a small number of trials of limited quality. No definite recommendation can be made based on the current evidence. Finally, the results for the treatment of BPH have been variable and recent high quality randomized controlled trials (RCTs) have suggested no benefit over placebo so at present it cannot be recommended for routine clinical practice. Future advances of BoNT-A include liposome encapsulated formulations which are being developed as an alternative to intravesical injections.

Abstract
Multiple sclerosis (MS) is a unique neurological disease with a broad spectrum of clinical presentations that are time- and disease course-related. Lower urinary tract symptoms (LUTS) are highly prevalent in this patient population, with approximately 90% showing some degree of voiding dysfunction and/or incontinence 6-8 years after the initial MS diagnosis. Major therapeutic goals include quality of life improvement and the avoidance of urological complications Owing to the wide divergence of clinical symptoms and disease course, evaluation and treatment differ between patients. Treatment must be customized for each patient based on disease phase, patient independence, manual dexterity, social support, and other medical- or MS-related issues. Ablative or irreversible therapies are indicated only when the disease course is stable. In most cases of "safe" bladder, behavioural treatment is considered first-line defense. Antimuscarinic drugs, alone or in combination with intermittent self-catheterization, are currently the mainstay of conservative treatment, and several other medications may help in specific disease conditions. Second-line treatment includes botulinum toxin A injection, neuromodulation, indwelling catheters, and surgery in well-selected cases.

Abstract
OBJECTIVE To examine whether response to first treatment with onabotulinumtoxinA is predictive of long-term treatment outcome in patients with neurogenic detrusor overactivity (NDO). PATIENTS AND METHODS Patients with NDO who were enrolled in a 3-year extension study (after a 52-week phase III study) received onabotulinumtoxinA 'as needed', based on fulfilment of prespecified retreatment criteria. This post hoc analysis included patients who received only the 200-U dose during the phase III and extension studies. Data on mean percent reduction from baseline in urinary incontinence (UI) episodes at week 6 after the first treatment were analysed, and the patients were stratified into three response groups: <50% (group 1; n = 33), 50-74% (group 2; n = 23), and 75-100% (group 3; n = 139). The following were assessed: change from baseline in mean percent UI reduction; proportions of patients who achieved ≥50% and 100% UI reduction after each subsequent treatment, and patients who achieved ≥50% UI reduction after all subsequent treatments; change from baseline in Incontinence Quality of Life (I-QOL) total summary score; and the proportion of patients who achieved or exceeded the minimally important difference (MID; +11 points) in I-QOL score. Adverse events (AEs) were also assessed. RESULTS The majority of the patients (83.1%; 162/195) experienced a ≥50% UI reduction after onabotulinumtoxinA treatment 1. Baseline characteristics were largely similar across the groups. After treatment 1, the mean percent reduction in UI remained consistent in subsequent treatments 2-6 for patients in response group 2 (range: 64.5-83.5%) and group 3 (range: 79.4-88.0%), but increased for those in the low response group (range: 36.3-60.3%). After treatment 1, the proportion of patients who achieved ≥50% reduction in UI episodes was consistent with subsequent treatments 2-6 in group 2 (range: 75.0-100%) and group 3 (range: 87.3-97.1%), but increased in the low response group (range: 48.3-72.7%). Even among those who achieved a low response after treatment 1, 37.9% of patients achieved ≥50% UI reduction in all subsequent treatments. Improvements in I-QOL scores in groups 2 and 3 were consistently 2-3 times the MID. In the low response group, at least 50% of the patients achieved or exceeded the MID with treatments 2-6. AEs were similar across all response groups and consistent across repeated treatments. CONCLUSION Patients with NDO with a ≥50% UI reduction after their first onabotulinumtoxinA treatment continued to experience consistent improvements in UI and quality of life with subsequent treatments over the duration of 4 years. A <50% UI reduction after first treatment did not necessarily predict low response with subsequent treatments. Thus, these results underscore the importance of attempting at least a second treatment with onabotulinumtoxinA before deeming patients unsuitable for onabotulinumtoxinA therapy.

Abstract
Botulinum toxin A (BoNT-A) has become an important therapeutic tool in the management of refractory overactive bladder (OAB). Over the last decade, there have been growing numbers of patients receiving repeat injections and these outcomes have begun to be reported in large, high-quality cohorts. This article reviews the current evidence for the medium- to long-term use of BoNT-A in adults with idiopathic detrusor overactivity (IDO) receiving repeat injections. We find that medium-term outcomes are encouraging but long-term outcomes are not as extensively reported. There is high-quality evidence that efficacy following the first injection persists across multiple treatment cycles. There are no additional safety concerns from repeat injections up to six treatment cycles. However, there is a need for further data to confirm the efficacy and safety of BoNT-A beyond the follow-up period in the current literature.

Abstract
The management of patients with neurogenic bladder has changed substantially over the past decades. Obtaining balanced lower urinary tract function has become possible in most patients, although, urological complications remain among the most serious complications these patients are likely to have and, even today, these can have a negative effect on quality of life. To this extent, patients with spinal cord injury (SCI) are likely to develop neurogenic bladder, and data are available on most aspects of neurogenic bladder in these patients. Data on physiology and pathophysiology form the basis of our understanding of patients' symptoms, and also provide a basis for the management of these patients. The use of conservative, and/or more invasive treatment measures, their complications and measures to prevent these complications, are all important clinical aspects that merit discussion. Considerable progress has been made in the urological management of patients with SCI over the past decades, but opportunities remain to make diagnosis more accurate and therapy more successful.

Abstract
Novel minimally invasive treatment options for the management of male lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO) aim to provide equal efficacy compared to standard techniques with a more favourable safety profile. The preservation of all aspects of male sexual function including antegrade ejaculation is increasingly important to patients. It should be ideally performed in an outpatient setting under local anesthesia to assure a short recovery time. Novel injectables for intraprostatic application (botulinum neurotoxin A, NX-1207, PRX302) have emerged and first phase III results could not confirm the promising initial data. For mechanical devices like Urolift® the early and mid-term benefits demonstrate a rapid and durable symptom relief without compromising sexual function. Novel innovative procedures like aquablation (AquaBeam®) are entering the scene, but their feasibility, efficacy and safety still need to be addressed in randomized controlled trials.

Abstract
Background The role of intravesical botulinum toxin A (BTX-A) injections in bladder pain syndrome/interstitial cystitis (BPS/IC) has not been clearly defined. The aim of this study was to evaluate high-level evidence regarding the efficacy and safety of BTX-A injections for BPS/IC. Material/Methods We conducted a comprehensive search of PubMed, Embase, and Web of Science, and conducted a systematic review and meta-analysis of all available randomized controlled trials (RCTs) and controlled studies assessing BTX-A injections for BPS/IC. Results Seven RCTs and 1 retrospective study were identified based on the selection criteria. Pooled analyses showed that although BTX-A was associated with a slightly larger volume of post-void residual urine (PVR) (weighted mean difference [WMD] 10.94 mL; 95% confidence intervals [CI] 3.32 to 18.56; p=0.005), patients in this group might benefit from greater reduction in pelvic pain (WMD −1.73; 95% CI −3.16 to −0.29; p=0.02), Interstitial Cystitis Problem Index (ICPI) scores (WMD −1.25; 95% CI −2.20 to −0.30; p=0.01), and Interstitial Cystitis Symptom Index (ICSI) scores (WMD −1.16; 95% CI −2.22 to −0.11; p=0.03), and significant improvement in daytime frequency of urination (WMD −2.36; 95% CI −4.23 to −0.49; p=0.01) and maximum cystometric capacity (MCC) (WMD 50.49 mL; 95% CI 25.27 to 75.71; p<0.00001). Nocturia, maximal urinary flow rate, dysuria, and urinary tract infection did not differ significantly between the 2 groups. Conclusions Intravesical BTX-A injections might offer significant improvement in bladder pain symptoms, daytime urination frequency, and MCC for patients with refractory BPS/IC, with a slightly larger PVR. Further well-designed, large-scale RCTs are required to confirm the findings of this analysis.

Abstract
AIMS Sacral neuromodulation (SNM) is a well-established treatment modality for refractory overactive bladder (OAB). There is a paucity of evidence examining the use of SNM in patients who have received prior intravesical onabotulinumtoxinA (BTXA) treatment. We aim to review those patients who underwent SNM for refractory OAB following treatment with BTXA. METHODS A retrospective review was conducted to identify patients who had undergone prior intradetrusor BTXA for refractory OAB, then subsequent first-stage SNM. Patient demographics, number/dosage of BTXA, voiding diaries, and patient global impression of improvement (PGI-I) scores were recorded. Successful first-stage SNM was defined as subjective patient improvement of greater than 50%. Patient satisfaction and device use at last follow-up was noted. RESULTS Eighty-three patients were identified having undergone SNM for OAB, of which 36 had prior BTXA treatment and were included in the series. 23/36 (63.9%) of patients had successful first-stage SNM, and underwent insertion of implantable pulse generator, compared to 33/47 (70.2%) in those who had never been treated with BTXA (P = 0.5). Mean PGI-I score was 2.6 (range 1-4). With a mean follow up of 29.1 months (range 12-53), 17/23 (73.9%) were satisfied, and using the device at last follow-up. CONCLUSION SNM is a suitable treatment option in those patients who have had prior BTXA treatment for refractory OAB, even in those for whom BTXA proved ineffective. Success rates were within the published range, and comparable to our own results, for SNM in OAB patients without prior BTXA treatment.

Abstract
BACKGROUND Neurogenic detrusor overactivity (NDO) affects the quality of life (QoL) of millions of individuals worldwide. The purpose of this study was to assess the efficacy and safety of onabotulinumtoxinA in patients with NDO using a network meta-analytic approach, which can also quantify and compare the efficacy of onabotulinumtoxinA across different dosages. METHODS PubMed, EMBASE, and the Controlled Trials Register were searched to identify randomized controlled trials comparing onabotulinumtoxinA to a control for NDO in adult patients. The primary outcome was the mean number of urinary incontinence (UI) episodes per week. Urodynamic parameters included the maximum cystometric capacity (MCC) and the maximum detrusor pressure (MDP). The safety of onabotulinumtoxinA was determined by the incidence of various frequent adverse events (AEs). Two authors extracted data independently, and the statistical analyses were performed using RevMan 5.1.0 software. RESULTS A total of 1,915 patients from six randomized controlled trials were included in this meta-analysis. The onabotulinumtoxinA-treated groups had a significantly decreased mean number of urinary incontinence episodes per week (at week 6) (onabotulinumtoxinA200U: MD: -10.72, 95% CI: -13.4 to -8.04, P<0.00001; 300 U: MD: -11.42, 95% CI: -13.91 to -8.93, P<0.00001), MDP (200 U: MD: -33.46, 95% CI: -39.74 to -27.18, P<0.00001; 300 U: MD: -31.72, 95% CI: -37.69 to -25.75, P<0.00001), and greater increased MCC (200 U: MD: 141.30, 95% CI: 121.28 to 161.32, P<0.00001; 300 U: MD: 151.39, 95% CI: 130.43 to 172.34, P<0.00001) compared to the placebo-treated groups. However, there were no significant differences between the onabotulinumtoxinA-treated groups for the number of weekly UI episodes at 6 weeks (MD: 0.08, 95% CI: -2.57 to 2.73, P = 0.95). Similarly, we also observed that there were no significant differences in MCC (MD: -9.97, 95% CI: -33.15 to 13.20, P = 0.40) and MDP (MD: -1.86, 95% CI: -8.09 to 4.37, P = 0.56). Considering the AEs, the onabotulinumtoxinA-treated groups were often associated with more complications, including urinary tract infections (UTIs) (RR: 1.47, 95% CI: 1.29 to 1.67, P<0.00001), urinary retention (RR: 5.58, 95% CI: 3.53 to 8.83, P<0.00001), hematuria (RR: 1.70, 95% CI: 1.01 to 2.85, P = 0.05), and muscle weakness (RR: 2.59, 95% CI: 1.36 to 4.91, P = 0.004). CONCLUSIONS OnabotulinumtoxinA can significantly reduce the frequency of urge urinary incontinence and improve urodynamic parameters (MCC and MDP) in patients with NDO at 6 weeks after treatment. This meta-analysis indicates that onabotulinumtoxinA is effective and safe for treating patients with NDO compared to placebo. Additionally, we did not observe any statistical or clinical differences in efficacy between 300 and 200 U dosages.

Abstract
INTRODUCTION Intravesical botulinum toxin (BoNT-A) is a safe and effective treatment for overactive bladder syndrome. There are many reports on the clinical experience with BoNT-A, especially in patients with neurogenic detrusor overactivity. The US Food and Drug Administration has recently approved its use for idiopathic overactive bladder (iOAB). Various studies have reported positive results for iOAB in the short-term. Yet little is known about the results after repeated BoNT-A injections. In this study, we evaluated the long-term results of botulinum toxin (BoNT-A) in women with iOAB. METHODS Patients treated with BoNT-A from 2004 until 2009 were evaluated in a non-academic teaching hospital (Zuyderland MC, Heerlen, the Netherlands). All female patients with a follow-up of >5 years with idiopathic bladder dysfunction were included. All patients received 200 U of onabotulinum toxin-A in 20 intradetrusor injections. In some patients, we applied a dose adjustment for repeated injections. Patients were instructed how to use clean intermittent self-catheterization (CISC) before the treatment. We advised patients to commence CISC if post-void residual exceeded 150 ml. RESULTS A total of 128 women were included. All patients had at least 5-year follow-up after their first injection. The mean follow-up was 97 (60-125) months. The mean age was 67 (46-88) years. Of all patients, 30 % were still on BoNT-A treatment at the last follow-up visit. Of the 70 % that discontinued treatment, 27 % had insufficient effect and 43 % had tolerability issues. Most patients discontinued treatment after the first (79 %) and second (19 %) injections. Only 2 % of patients discontinued treatment after more than two injections during follow-up. CONCLUSION Intravesical BoNT-A is an effective treatment for women with idiopathic OAB. However, in time, almost two-thirds of patients in our study discontinued therapy. Most patients discontinue treatment after one or two injections and mainly due to tolerability issues.
