Safety and efficacy of beta-3 adrenergic agonists in treating neurogenic lower urinary tract dysfunction: A systematic review and meta-analysis.

PURPOSE: To evaluate efficacy and safety of beta-3 adrenergic agonists in adults with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: According to a protocol (CRD42022350079), we searched multiple data sources for published and unpublished randomized controlled trials (RCTs) up to 2nd August 2022. Two review authors independently screened studies and abstracted data from the included studies. We performed statistical analyses by using a random-effects model and interpreted them according to the Cochrane Handbook for Systematic Reviews of Interventions. We used GRADE guidance to rate the certainty of evidence (CoE). RESULTS: We found data to inform two comparisons: beta-3 adrenergic agonists versus placebo (4 RCTs) and anticholinergics (2 RCTs). Only mirabegron was used for intervention in all included studies. Compared to placebo, beta-3 adrenergic agonists may have a clinically unimportant effect on urinary symptoms score (mean difference [MD] -2.50, 95% confidence interval [CI] -4.78 to -0.22; I²=92%; 2 RCTs; 192 participants; low CoE) based on minimal clinically important difference of 3. We are very uncertain of the effects of beta-3 adrenergic agonists on quality of life (MD 10.86, 95% CI 1.21 to 20.50; I²=41%; 2 RCTs; 98 participants; very low CoE). Beta-3 adrenergic agonists may result in little to no difference in major adverse events (cardiovascular adverse events) (risk ratio 0.57, 95% CI 0.14 to 2.37; I²=0%; 4 RCTs; 310 participants; low CoE). Compared to anticholinergics, no study reported urinary symptom scores and quality of life. There were no major adverse events (cardiovascular adverse events) in either study group (1 study; 60 participants; very low CoE). CONCLUSIONS: Compared to placebo, beta-3 adrenergic agonists may have similar effects on urinary symptom scores and major adverse events. There were uncertainties about their effects on quality of life. Compared to anticholinergics, we are either very uncertain or have no evidence about urinary symptom scores, quality of life, and major adverse events.

Clinical and microbiological characteristics of female patients with acute pyelonephritis who experienced urinary tract infections within the previous year.

BACKGROUND: This study aimed to examine the clinical and microbiological characteristics of female patients with recurrent acute pyelonephritis (APN). METHODS: A retrospective cohort study was conducted at a tertiary care hospital in South Korea from July 2019 to December 2021. All female patients aged ≥ 19 years who were diagnosed with community-acquired APN on admission were enrolled. The recurrent group included patients with APN who experienced urinary tract infections within the previous year. The clinical characteristics, types of causative organisms, major antibiotic resistance, and molecular characteristics of Escherichia coli strains were compared between the recurrent and non-recurrent groups. RESULTS: A total of 285 patients with APN were analyzed, including 41 (14.4%) in the recurrent group. Compared to the non-recurrent group, the recurrent group had a higher Charlson Comorbidity Index (1.8 ± 2.1 vs. 1.1 ± 1.5; P = 0.01) and a higher proportion of bladder abnormalities, such as neurogenic bladder (12.2% vs. 2.0%; P = 0.001) and urinary catheterization (12.2% vs. 1.6%; P < 0.001). Escherichia coli was the most common causative organism in both groups. The proportion of Klebsiella pneumoniae (17.1% vs. 4.7%; P = 0.007) and Pseudomonas aeruginosa (5.7% vs. 0.5%; P = 0.014) as a causative organism was higher in the recurrent group. Regarding the microbiological characteristics of Escherichia coli, there were no significant differences in the proportion of antibiotic resistance, phylogenetic groups, resistance genes, and virulence factors between the two groups. Multivariable analysis showed that neurogenic bladder and a history of admission or antibiotic use during 1 year prior to inclusion were significantly associated with recurrent APN. CONCLUSIONS: The proportion of causative organisms except Escherichia coli was higher in the recurrent group than in the non-recurrent group. Neurogenic bladder and a history of admission or antibiotic use during 1 year prior to inclusion were risk factors for recurrent APN.

Efficacy and safety of the implantable, magnetic resonance imaging-compatible StimRouter neuromodulation system in the treatment of refractory lower urinary tract symptoms in multiple sclerosis patients.

BACKGROUND AND PURPOSE: Lower urinary tract symptoms (LUTS) significantly affect quality of life (QoL) of multiple sclerosis (MS) patients, and pharmacotherapy has limited efficacy. We investigated efficacy and safety of the implantable StimRouter neuromodulation system for treating refractory LUTS in MS. METHODS: This prospective, single-center, clinical trial was conducted at the Multiple Sclerosis Center of Lugano, Switzerland, involving MS patients treated with self-administered percutaneous tibial nerve stimulation delivered by StimRouter over 24 weeks. Changes in video-urodynamic parameters as well as LUTS severity were measured by Overactive Bladder Questionnaire (OAB-q), QoL using the Multiple Sclerosis Quality of Life (MSQoL-54), and treatment satisfaction using a 1-10 visual analogue scale. Adverse events were also recorded. RESULTS: Of 23 MS patients recruited, six had neurogenic detrusor overactivity (NDO), five had detrusor sphincter dyssynergia (DSD), and 12 had both NDO and DSD. Of patients with NDO, median bladder volume at first uninhibited contraction significantly increased from baseline to week 24 (median = 136 mL, interquartile range [IQR] = 101-244 mL vs. 343 mL, IQR = 237-391 mL; ß = 138.2, p = 0.001). No significant changes of urodynamic parameters were found in patients with DSD. OAB-q symptom scores progressively decreased, and OAB-q quality of life scores increased (ß = -0.50, p < 0.001 and ß = 0.47, p < 0.001, respectively), whereas MSQoL-54 scores did not significantly change (ß = 0.24, p = 0.084) in the overall population. Treatment satisfaction was overall high (median = 8, IQR = 6-9). No serious adverse events were recorded. CONCLUSIONS: StimRouter represents a minimally invasive, magnetic resonance imaging-compatible, self-administered neuromodulation device leading to objective and subjective improvements of OAB symptoms and related QoL in MS patients with refractory LUTS.

Detrusor relaxing agents for neurogenic detrusor overactivity: a systematic review, meta-analysis and network meta-analysis.

OBJECTIVE: To evaluate the evidence regarding the therapeutic benefits and safety of oral detrusor relaxing agents (DRAs) in treating neurogenic detrusor overactivity (NDO). METHODS: A comprehensive search was performed on 1 September 2022. Two authors independently reviewed the articles to extract data using a pre-designed form. The meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. A common-effect or random-effects model was used based on the heterogeneity among studies. Bayesian network meta-analysis (NMA) was further performed to make indirect comparisons of antimuscarinics and mirabegron. RESULTS: A total of 23 randomised controlled trials (RCTs) comprising 1697 patients were included in our analysis. Compared to placebo, the clinical benefits of oral DRAs, along with more adverse events (AEs), were demonstrated in the treatment of NDO. In the subgroup analysis, antimuscarinics significantly improved both urodynamic and bladder diary outcomes (including urinary incontinence episodes, urinary frequency, and residual volume), with a higher rate of AEs, such as xerostomia. Mirabegron improved some of the parameters and had fewer bothersome side-effects in patients with NDO. The NMA showed that none of the antimuscarinics or mirabegron was superior or inferior to the other. CONCLUSIONS: Detrusor relaxing agents are associated with improved outcomes in patients with NDO and our analysis has added new evidence regarding antimuscarinics. Evidence concerning mirabegron as first-line therapy for NDO is still limited. Well-designed RCTs are still required in this specific population.

[Bladder augmentation in the era of botulinum toxin: Indications and results]. / L'entérocystoplastie d'agrandissement à l'ère de la toxine botulique : indications et résultats.

AIM: To determine the surgical indication and results of bladder augmentation (BA) during the last decade in a neurourology center in the era of intradetrusor botulinum toxin injection. MATERIAL: We conducted a retrospective study that included patients with BA between January 1, 2012 and December 31, 2022 in our centre. We collected pre-operative demographic, clinical, and urodynamic data, BA indication, and associated procedures. We analyzed early and late complications as well as continence and postoperative voiding mode in patients with first BA in a neurological pathology context. RESULTS: We performed 77 BA over the study period. The main indication was neurogenic overactive bladder, which was secondarily resistant to botulinum toxin. The main associated procedure was continent cutaneous diversion (n=31, 57.4%). Among patients who had a first BA for neurogenic bladder, 34 patients had early complications (50%) including 12 patients with≥Clavien 3 complications (17.6%). After a median follow-up of 33 [14; 55] months, 23 patients had late complications (33.8%) and 59 patients had complete continence (86.8%). CONCLUSION: In the era of botulinum toxin, the main indication of BA is the secondary failure of botulinum toxin for overactive neurogenic bladder. The BA provided continence in 86.8% of patients. It remains however an intervention with a significant rate of severe complications whose indication must be discussed by a multidisciplinary team. LEVEL OF EVIDENCE: Weak.

Switching from onabotulinum toxin A to abobotulinum toxin A for treating detrusor overactivity in spinal cord injured patient, does it really work?

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.

Evaluating the utility of routine urine culture and antibiotic treatment in children with neurogenic bladder undergoing intradetrusor OnabotulinumtoxinA injection.

INTRODUCTION: OnabotulinumtoxinA is used as treatment for refractory idiopathic and neurogenic detrusor overactivity in children. Many patients perform intermittent self-catheterization and therefore have higher rates of asymptomatic bacteriuria, which may increase their risk of symptomatic urinary tract infection (UTI) following treatment. Multiple injections are often needed due to the short-term efficacy of onabotulinumtoxinA treatment, which may also increase the risk of UTI. OBJECTIVE: We aim to evaluate whether a sterile urinary tract is necessary to decrease the risk of postoperative UTI in pediatric patients treated with onabotulinumtoxinA. STUDY DESIGN: A retrospective review of patients undergoing intradetrusor onabotulinumtoxinA injection from 2014 to 2021 was performed. Demographic data, clinical characteristics, antibiotic treatment and culture results were collected. A positive urine culture was defined as ≥ 103 CFU/ml of uropathogenic bacteria. Our primary outcome was symptomatic UTI within 14 days of the procedure. RESULTS: 103 patients underwent 158 treatments with onabotulinumtoxinA. The incidence of postoperative UTI was 3.2%. The incidence of symptomatic postoperative UTI in patients with asymptomatic bacteriuria compared to those with sterile urine was not significantly different (3.8% vs 0%, p = 0.57). Obtaining a preoperative urinalysis or urine culture did not affect the incidence of postoperative UTI (p = 0.54). The number needed to treat with antibiotics to prevent one postoperative UTI was 27. The incidence of postoperative UTI was highest in patients with low-risk bladders (p = 0.043). Prior history of multi-drug resistant UTI was a risk factor for postoperative UTI (p = 0.048). DISCUSSION: For children undergoing onabotulinumtoxinA injection, there are no evidence-based recommendations regarding antibiotic prophylaxis and the need to screen for and treat asymptomatic bacteruria prior to treatment. Our study addresses this important clinical question, and shows no difference in the rate of postoperative UTI between patients with asymptomatic bacteriuria and those with sterile urine. Patients with a history of multi-drug resistant UTI are at increased risk of symptomatic postoperative UTI and may benefit from preoperative urine testing and treatment. Limitations of our retrospective study include its small sample size in the face of such a low incidence of our primary outcome. CONCLUSIONS: The risk of UTI following onabotulinumtoxinA injection in children is low. The presence of sterile urine at the time of surgery does not significantly decrease the risk of postoperative UTI. Routine treatment of asymptomatic bacteriuria prior to surgery results in a large number of patients receiving unnecessary antibiotics. As a result, we recommend against preoperative urine testing for most asymptomatic patients.

An evaluation of onobotulinumtoxinA as a therapeutic option for pediatric neurogenic detrusor overactivity.

INTRODUCTION: Neurogenic detrusor overactivity (NDO) results in involuntary detrusor contractions during bladder filling or storage risking transmission of pressure to the upper urinary tracts and/or significant incontinence. The goals of bladder management in children with NDO prioritize the preservation of renal function, prevention of UTIs, and optimizing quality of life. First-line measures include intermittent catheterization and anticholinergic medication. However, when conservative measures fail, surgical intervention may be indicated. Historically, the next step was major reconstructive surgery to create a low-pressure urinary reservoir. The introduction of intravesical botulinum neurotoxin A (BoNT/A) for use in children in 2002 offered a less invasive option for management. However, its exact role is still evolving. AREAS COVERED: This article summarizes the mechanism of action of BoNT/A for management of NDO and evaluates the current literature defining common practice and clinical efficacy in children with NDO. The findings of the recently completed phase III trial for intravesical onabotulinumtoxinA in children are discussed in detail. EXPERT OPINION: As the first BoNT/A approved for use in children with NDO, onabotulinumtoxinA appears to be a safe and less invasive alternative to major reconstructive surgery. However, data defining appropriate patient selection and its role as a long-term treatment option continue to develop.

[bobotulinum toxin A (Dysport) for the treatment of neurogenic detrusor overactivity].

Increasing of treatment efficiency in patients with neurogenic detrusor overactivity is an important medical and social problem. Its significance is determined not only by the high prevalence of neurogenic lower urinary tract dysfunctions, but also by the high risk of complications, among which an impaired renal function takes the leading place. Botulinum toxin therapy is considered as a second-line treatment and is carried out in case of insufficient efficacy, unsatisfactory tolerability or the presence of contraindications to anticholinergic therapy. Botulinum toxin therapy has been actively used in our country for more than 12 years. In 2022, abobotulinum toxin A (Dysport) was registered in the Russian Federation for the treatment of neurogenic detrusor overactivity. An overview of the results of clinical trials of Dysport, indicating its high efficacy and favorable safety profile, is presented in the article. The availability of botulinum toxin in the arsenal of a urologist, which has a high efficiency, opens up additional prospects for the treatment of patients with a neurourological profile.

Cost analysis for mirabegron use in the treatment of children with neurogenic bladder.

INTRODUCTION: Mirabegron is a beta-3 adrenergic receptor agonist that received FDA approval in 2021 to treat neurogenic detrusor overactivity (NDO) in children ages three years and older. Despite its safety and efficacy, access to mirabegron frequently remains restricted by payor coverage policies. OBJECTIVE: This cost minimization study sought to determine the cost implications from a payor perspective of mirabegron use at different points in the treatment pathway for pediatric NDO. STUDY DESIGN: A Markov decision analytic model was constructed to assess the costs for eight treatment strategies over a 10-year period, using six-month cycles (Table). Five strategies involve mirabegron use as first-, second-, third-, or fourth-line therapy. Two strategies, including the "base case," entail use of anticholinergic medications followed by onabotulinum toxin type A (Botox) injection and augmentation cystoplasty. A strategy involving first-line Botox was also modeled. The effectiveness, adverse event rates, attrition rates, and costs associated with each treatment option were obtained from the clinical literature and adjusted to a six-month cycle. Costs were adjusted to 2021-dollar value. A discount rate of 3% was used. To quantify uncertainty, costs and treatment transition probabilities were modeled as gamma and PERT distributions, respectively. One-way sensitivity analyses were performed. Probabilistic sensitivity analysis (PSA) was conducted using a Monte Carlo simulation with 100,000 iterations. Analyses were performed using Treeage Pro (Healthcare Version). RESULTS: The least costly strategy involved first-line mirabegron (expected cost $37,954). All strategies involving mirabegron were less costly than the base case ($56,417). On PSA, first-line mirabegron was the least costly strategy in 88.9% of cases (mean $37,604, 95% CI: $37,579-37,628); in 100% of cases, the least costly strategy involved mirabegron use. Cost savings associated with mirabegron use were attributable to decreased use of augmentation cystoplasty and Botox injections. DISCUSSION: This is the first study to compare costs across multiple strategies involving mirabegron to treat pediatric NDO. Mirabegron use likely yields cost savings for the payor: the least costly strategy involved first-line mirabegron, and all pathways incorporating mirabegron were less costly than those without mirabegron use. These findings provide an updated cost analysis for the treatment of NDO by investigating mirabegron use alongside more established treatment options. CONCLUSION: Use of mirabegron for the treatment of pediatric NDO is likely associated with cost savings as compared to treatment pathways without mirabegron. Expansion of payor coverage for mirabegron, as well as clinical studies to study first-line mirabegron use, should be considered.

[Efficacy of fesoterodine for prevention of autonomic dysreflexia in patients with neurogenic dysfunction of the bladder after spinal cord injury].

AIM: to evaluate the effectiveness of fesoterodine for the prevention of autonomic dysreflexia (AD) in patients with neurogenic bladder dysfunction (NBD) after spinal cord injury (SCI). MATERIALS AND METHODS: a total of 53 patients with AD were included in the study. In the main group (n=33) patients received fesoterodine 4 mg per day for 12 weeks as a treatment for neurogenic bladder dysfunction and prevention of AD. In the control group (n=20), patients were monitored for 12 weeks without specific treatment. The assessment was based on the results of ADFSCI and NBSS questionnaires, daily blood pressure monitoring with the completion of a self-observation diary, cystometry with simultaneous monitoring of blood pressure and heart rate. RESULTS: In the main group there was a significant decrease in episodes and severity of AD according to ADFSCI questionnaire and an improvement in the quality of life according to NBSS questionnaire compared to the control group (p<0.001). Also, in the main group, the number of episodes of AD and systolic blood pressure decreased. The maximum bladder capacity and bladder compliance increased (p<0.001), and the maximum detrusor pressure and systolic blood pressure when the cystometric capacity was reached, decreased significantly (p<0.001) in the main group compared in comparison with the control group. CONCLUSION: Fesoterodine at a dosage of 4 mg for 12 weeks reduced the severity of symptoms of AD in patients with SCI and NBD, which was manifested by the stabilization of blood pressure and a decrease in the number of episodes of AD, which significantly improved the quality of life. Also, the drug led to a significant improvement in urodynamic parameters during cystometry, in the form of a decrease in detrusor pressure and an increase in cystometric capacity. We can conclude that fesoterodine is effective in the prevention of AD in patients with NBD after SCI.

Intravesical injections of botulinum neurotoxin A to treat overactive bladder and/or detrusor overactivity related to multiple sclerosis: 5-Year continuation rate and specific risk factors for discontinuation-A study from the neuro-urology committee of the French Association of Urology.

BACKGROUND: While intravesical injections of botulinum neurotoxin A (BoNT-A) are currently recommended for patients experiencing refractory neurogenic overactive bladder and/or detrusor overactivity (OAB/DO), it is unclear how much this therapy is effective and sustainable in the long-term in patients with multiple sclerosis (MS). OBJECTIVES: To assess the mid-term continuation rate of BoNT-A injections to treat neurogenic OAB/DO in MS patients and to investigate MS-specific risk factors for discontinuation. METHODS: This retrospective study involved 11 French university hospital centers. All MS patients who received BoNT-A to treat neurogenic OAB/DO between 2008 and 2013 and were subsequently followed up for at least 5 years were eligible. RESULTS: Of the 196 MS patients included, 159 (81.1%) were still under BoNT-A 5 years after the first injection. The combination of the Expanded Disability Status Scale (EDSS < 6 or ⩾ 6) and of the MS type (relapsing-remitting vs progressive) predicted the risk of discontinuation. This risk was 5.5% for patients with no risk factor, whereas patients presenting with one or two risk factors were 3.3 and 5.7 times more likely to discontinue, respectively. CONCLUSION: BoNT-A is a satisfying mid-term neurogenic OAB/DO therapy for most MS patients. Combining EDSS and MS type could help predict BoNT-A discontinuation.

Recurrent Urinary Tract Infection in Adult Patients, Risk Factors, and Efficacy of Low Dose Prophylactic Antibiotics Therapy.

BACKGROUND: Recurrent urinary tract infection (UTI) occurs in sizable percentages of patients after a single episode and is a frequent cause of primary healthcare visits and hospital admissions, accounting for up to one quarter of emergency department visits. We aim to describe the pattern of continuous antibiotic prophylaxis prescription for recurrent urinary tract infections, in what group of adult patients they are prescribed and their efficacy. METHODS: A retrospective chart review of all adult patients diagnosed with single and recurrent symptomatic urinary tract infection in the period of January 2016 to December 2018. RESULTS: A total of 250 patients with a single UTI episode and 227 patients with recurrent UTI episodes were included. Risk factors for recurrent UTI included diabetes mellitus, chronic renal disease, and use of immunosuppressive drugs, renal transplant, any form of urinary tract catheterization, immobilization and neurogenic bladder. E. coli infections were the most prevalent organism in patients with UTI episodes. Prophylactic antibiotics were given to 55% of patients with UTIs, Nitrofurantoin, Bactrim or amoxicillin clavulanic acid. Post renal transplant is the most frequent reason to prophylaxis antibiotics (44%). Bactrim was more prescribed in younger patients (P < 0.001), in post-renal transplantation (P < 0.001) and after urological procedures (P < 0.001), while Nitrofurantoin was more prescribed in immobilized patients (P = 0.002) and in patients with neurogenic bladder (P < 0.001). Patients who received continuous prophylactic antibiotics experienced significantly less episodes of urinary tract infections (P < 0.001), emergency room visits and hospital admissions due to urinary tract infections (P < 0.001). CONCLUSION: Despite being effective in reducing recurrent urinary tract infection rate, emergency room visits and hospital admissions due to UTI, continuous antibiotic prophylaxis was only used in 55% of patients with recurrent infections. Trimethoprim/sulfamethoxazole was the most frequently used prophylactic antibiotic. Urology and gynecological referral were infrequently requested as part of the evaluation process for patients with recurrent UTI. There was a lack of use of other interventions such as topical estrogen in postmenopausal women and documentation of education on non-pharmacological methods to decrease urinary tract infections.

[Drugs for Neurogenic Bladder Dysfunction].

Urinary dysfunction includes an overactive bladder (OAB), post-void residual (PVR)/retention, or both entities. Brain diseases cause OAB, peripheral neuropathies are associated with significant PVR/retention, and multisystem atrophy/spinal cord diseases result in a combination of OAB and PVR/retention. Selective beta 3 adrenergic receptor agonists or anticholinergic agents are the first-choice treatment for OAB and clean intermittent self-catheterization, alpha-blocker and cholinergic stimulant therapy for significant PVR/retention. These therapies may be useful to maximize patients' quality of life and prevent serious complications, such as urosepsis or kidney dysfunction.

Understanding factors influencing primary treatment with intradetrusor onabotulinumtoxinA versus augmentation cystoplasty in patients with spina bifida.

PURPOSE: Surgical interventions in the urologic management of children with neurogenic bladder secondary to spina bifida aim to preserve upper tract function, prevent urinary tract infections, and optimize quality of life. However, since the introduction of intravesical onabotulinumtoxinA (Botox) in the management of these patients, the indications for choosing Botox over augmentation cystoplasty (AC) remain undefined. The objective of this study was to determine which factors lead patients to undergo Botox versus AC as a primary surgical treatment after failing medical management. METHODS: We retrospectively reviewed the records of pediatric patients with myelomeningocele undergoing either primary Botox or primary AC at our institution between 2013 and 2018. We recorded demographic and clinical information. We identified 10 important clinical decision-making factors: bladder trabeculation, vesicoureteral reflux, or hydronephrosis on imaging; end-filling pressure (EFP) ≥40 cm H2O, detrusor overactivity, detrusor-sphincter dyssynergia, or reduced capacity on urodynamic studies; physician-perceived bladder hostility; and patient/family desire for continence and independence. The presence of these factors was compared between patients undergoing either primary Botox or primary AC. RESULTS: We identified 14 and 50 myelomeningocele patients who underwent primary AC and primary Botox, respectively. We found no significant differences in age, sex, race, or history of reconstructive surgery (antegrade continence enema or catheterizable channel). For the 10 decision-making factors, desire for independence/continence (p = <0.001) and reduced capacity (p = 0.002) were significantly associated with AC, while trabeculation (p = 0.006), EFP ≥40 cm H2O (p = 0.029), rising slope (p = 0.019), and physician-perceived hostility (p = 0.012) were significantly more common with Botox. CONCLUSIONS: At our institution, quality of life measures prompted AC over objective urodynamic or imaging findings before attempting Botox. These findings support a shared decision-making approach when considering surgical intervention for neurogenic bladder secondary to myelomeningocele.

Trends in Botulinum Toxin Use among Patients with Multiple Sclerosis: A Population-Based Study.

There are limited real-world data on the use of botulinum toxin type A (BoNT-A) in patients with multiple sclerosis (MS). Accordingly, this nationwide, population-based, retrospective cohort study aimed to describe BoNT-A treatment trends in patients with MS between 2014 and 2020 in France. This study extracted data from the French National Hospital Discharge Database (Programme de Médicalisation des Systèmes d'Information, PMSI) covering the entire French population. Among 105,206 patients coded with MS, we identified those who received ≥1 BoNT-A injection, administered within striated muscle for MS-related spasticity and/or within the detrusor smooth muscle for neurogenic detrusor overactivity (NDO). A total of 8427 patients (8.0%) received BoNT-A injections for spasticity, 52.9% of whom received ≥3 BoNT-A injections with 61.9% of the repeated injections administered every 3 to 6 months. A total of 2912 patients (2.8%) received BoNT-A injections for NDO, with a mean of 4.7 injections per patient. Most repeated BoNT-A injections within the detrusor smooth muscle (60.0%) were administered every 5 to 8 months. There were 585 patients (0.6%) who received both BoNT-A injections within striated muscle and the detrusor smooth muscle. Overall, our study highlights a broad range of BoNT-A treatment practices between 2014 and 2020 in patients with MS.

Treating Neurogenic Lower Urinary Tract Dysfunction in Chronic Spinal Cord Injury Patients-When Intravesical Botox Injection or Urethral Botox Injection Are Indicated.

Lower urinary tract symptoms (LUTS), such as urgency, urinary incontinence, and/or difficulty voiding, hamper the quality of life (QoL) of patients with spinal cord injury (SCI). If not managed adequately, urological complications, such as urinary tract infection or renal function deterioration, may further deteriorate the patient's QoL. Botulinum toxin A (BoNT-A) injection within the detrusor muscle or urethral sphincter yields satisfactory therapeutic effects for treating urinary incontinence or facilitating efficient voiding; however, adverse effects inevitably follow its therapeutic efficacy. It is important to weigh the merits and demerits of BoNT-A injection for LUTS and provide an optimal management strategy for SCI patients. This paper summarizes different aspects of the application of BoNT-A injection for lower urinary tract dysfunctions in SCI patients and provides an overview of the benefits and drawbacks of this treatment.
