Predictive Factors for Clean Intermittent Catheterization after Intravesical OnabotulinumtoxinA Injections in Women with Overactive Bladder: a Danish Retrospective Cohort Study.

We aimed to evaluate the clean intermittent catheterization (CIC) rate in women undergoing their first OnabotulinumtoxinA (BTX-A) treatment and to investigate factors predictive of initiating CIC. This was a retrospective cohort of women, who had their first BTX-A treatment for symptoms of overactive bladder (OAB) syndrome, with a pretreatment urodynamic study (UDS). We reviewed demographic, medical and gynecological history, UDS, pretreatment bladder diaries, objective examinations, BTX-A treatment details, and post-void residual (PVR) reports in the electronic medical record. Botox® Allergan 100 International Units were injected into the detrusor at 10-20 sites. Statistical analyses included univariate and multivariate logistic regression analyses. We included 397 women. Median age was 68 (Q1-Q3: 54-76) years. CIC rate was 8.6% (n = 34) following the first BTX-A treatment. Urgency urinary incontinence (UUI) reduced the risk of undergoing CIC (OR 0.30, 95% CI 0.09-0.97). A bladder capacity of 500ml or greater in the bladder diary increased the risk of CIC (OR 2.46, 95% CI 1.06-5.70), whereas reported leakages were associated with a decreased risk of CIC (OR 0.24, 95% CI 0.10-0.57). Multivariate logistic regression analysis showed that anterior colporrhaphy (OR 3.71, 95% CI 1.52-9.06) and 10-ml increments in median maximum cystometric capacity (OR 1.03, 95% CI 1.00-1.06) predicted CIC, whereas UUI was a protective factor for CIC (OR 0.23, 95% CI 0.07-0.79). A history of anterior colporrhaphy, large bladder capacity, and absence of incontinence episodes in bladder diary or UDS were risk factors for CIC after the first BTX-A treatment.

Clean Intermittent Catheterisation via a Mitrofanoff is superior to long term Suprapubic Catheters for Bladder Drainage.

AimSome children require long-term drainage of the bladder but do not tolerate clean intermittent catheterisation (CIC) urethrally. We aimed to compare long term suprapubic catheter (SPC) drainage vs Mitrofanoff conduit (allowing CIC) by comparing the survival of the drainage methods and rates of urinary tract infection (UTI). MethodRetrospective review of a single surgeon’s experience (2007-2023). Data collection included diagnosis, age at procedures, date of surgery, date of most recent follow-up and date and reason for unplanned surgery. For SPCs, initial insertion of SPC and then conversion to a Foley catheter under GA was taken as normal (event free survival) and only further operations were counted as complication events. For Mitrofanoffs, any subsequent operation was counted as a complication.Data were given as a number (%) or median (interquartile range) as appropriate. Data analysed by Fisher exact and Mann-Whitney U-test. Kaplan Meier (KM) survival of drainage routes was compared, P<0.05 taken as significant. ResultsThere were 45 patients (n = 86 SPC episodes) compared to 108 patients (n = 110 Mitrofanoff procedures). Data were available in 73 SPC episodes and 109 Mitrofanoff episodes, including 3 redo procedures (one from another centre). There was no difference in gender (SPC group, 67% male vs. Mitrofanoff group, 77%; N.S.). There was no difference in age at procedure [7.5 (2.9 - 11.5) years vs 8.3 (5.9 - 11.4) years respectively; N.S.)KM comparison showed that Mitrofanoff have a better event-free survival than SPC (91% vs 52% at 1 year; 80% vs. 13% at 5 years; P<0.0001). Paired data showed a significant (86%) reduction in rate of UTI with conversion from SPC to Mitrofanoff drainage in 15 patients; SPC: 0.13 (0 - 0.46) UTIs/month vs subsequent Mitrofanoff: 0.02(0 - 0.08) UTI/month, P=0.04). ConclusionSPCs had a much higher rate of unplanned surgery than Mitrofanoffs, creating a considerable unplanned burden of care for families and clinical staff. For long-term bladder drainage CIC via a Mitrofanoff conduit should be considered in preference to SPC where urethral CIC is not possible.

Switching from intermittent catheterization with single-use catheter to a reusable catheter has a negative impact on quality of life.

It has been proposed that reusable catheters are more cost effective and environmentally sustainable than single-use catheters intended for intermittent catheterization (IC). However, the aspect of individuals' well-being and preference for catheter type is not considered. In this study, we investigated the impact on individuals' health-related quality of life (HR-QoL) when testing a reusable catheter. The study was an open-labeled, single-arm, multicenter investigation with a treatment period of 28 days. Forty subjects using single-use hydrophilic catheters were accustomed to a reusable catheter for managing IC. HR-QoL was evaluated by the Intermittent-Self Catheterization Questionnaire (ISC-Q). Additionally, satisfaction was evaluated by the Intermittent Catheterization Satisfaction Questionnaire (InCaSa-Q). The difference in total score was analyzed using a mixed linear model. Furthermore, preference for IC (single-use vs. reusable) was assessed and microbial evaluation of the catheters was performed. The total ISC-Q score measuring HR-QoL decreased significantly by 28% (p < 0.001). Two of the four subdomains (ease-of-use and discreetness) also decreased significantly (p < 0.001). The total InCaSa-score and all four subdomains evaluating satisfaction decreased significantly (p < 0.005). The primary study results were supported by the fact that 90.9% of subjects preferred to use a single-use catheter for IC. Furthermore, 50% of reusable catheters were contaminated with bacteria. Switching from single-use to reusable IC resulted in a significant decrease in HR-QoL and satisfaction. Moreover, the vast majority preferred the single-use catheter due to handling and convenience. The users' rights to their preferred bladder management method should be acknowledged.

Intradetrusor OnabotulinumtoxinA outcomes for overactive bladder in older adults

Introduction:In older adults, pharmacological treatment of overactive bladder (OAB) with anticholinergics and beta-3 agonists could be associated with negative cognitive effects; highlighting the need for alternative treatment modalities. Currently, there is relatively little evidence assessing outcomes of onabotulinomtoxin-A injection as thirdline therapy in this population. This study sought to evaluate the outcomes of intradetrusor BTX-A injection in patients over 70 years of age between August 2014 March 2022. Methods:A retrospective chart review was performed on patients with a clinical diagnosis of OAB and who underwent an initial intradetrusor onabotulinomtoxinA injection at 70 years or older from three US centers. Patient characteristics and self-reported symptoms before and after injection were statistically analyzed. Results:Amongst the 210 patients, 94% reported urinary urgency, 92% reported urgency urinary incontinence, and 89% reported daytime frequency. The most common medications initially prescribed were beta-3 agonist at 66% and anticholinergics at 65%. Following treatment, 80% reported >50% improvement in incontinence, 81% in urgency, 79% in daytime frequency, and 78% in nocturia. Temporary de novo intermittent catheterization was initiated in 8/210 (3.8%) patients, and one (0.5%) required indwelling catheter placement; with 67% returning for repeat injections. Thirty-six (17%) had a symptomatic urinary tract infection at follow-up. Seventy-five percent of patients did not require drug therapy following injection. In a subgroup analysis of octogenarians (n = 50/210), 73% showed improvement in urgency and 68% had less incontinence post-injection. Discussion:OnabotulinomtoxinA was well tolerated in patients older than 70 with improvement in overactive bladder symptoms and reduction in requirement of drug therapy.

Contemporary Outcomes of a National Fetal Spina Bifida Surgery Service.

To assess contemporary outcomes of fetuses who underwent open fetal spina bifida surgery in Canada. Our clinical program prospectively collected outcomes of all consecutive fetuses who underwent open fetal spina bifida closure at the Ontario Fetal Center in Toronto and who were at least 1year of age at the time of postnatal follow-up. We gathered information on the need for hydrocephalus treatment, motor function, bladder function, as well as neurodevelopment (Ages and Stages Questionnaire and Bayley's scales of infant development). Developmental outcomes were categorized as "Typical Development," "Possible Delay," or "Significantly Delayed." Between 2017 and 2022, 41 fetuses underwent open fetal spina bifida closure. Twenty-four patients (58.5%) responded to the questionnaire at a median age of 46.5months. Eight children (33.3%) required CSF diversion procedures. Bladder management included clean intermittent catheterization (43.5%), spontaneous voiding (34.8%), or both (21.7%), with 43.5% needing medication for overactive bladder. All patients could sit independently, with 50% walking outside and 50% crawling indoors. Among those walking outdoors (50%), 25% did so without orthotics or aid, 58.3% with orthotics, and 16.7% required additional walking aids. Most children demonstrated typical communication and problem-solving skills (79.2%), while gross motor development was significantly delayed in 91.7% of cases. Fine motor skills varied, with 56.5% showing typical development and 34.8% possibly experiencing delays. This study showed a mixed developmental profile among patients who underwent open fetal spina bifida repair, consistent with the MOMs trial findings.

Impact of urinary catheters including reusable catheters on quality of life and work productivity in persons with spinal cord lesion

While preventing renal damage and symptomatic urinary tract infection are of paramount importance to persons with a spinal cord lesion (SCL), patient-reported outcomes (PROs) are receiving much more attention than ever before. We performed a cross-sectional internet survey of 282 adult members of SCL patient advocacy groups and investigated, for the first time, the impact of different types of urinary catheter, including a Japanese reusable silicone catheter and a reusable intermittent balloon catheter, on PROs of persons with SCL. Intermittent self-catheterization (ISC) did not surpass continuous indwelling catheterization in terms of a disease-specific urinary quality of life. Urinary incontinence, regular ISC, and performing ISC away from home confronted these individuals. Work productivity and regular activities correlated fairly well with the disease-specific urinary quality of life. Bowel management problems affected all PROs evaluated. The absence of differences in PROs among the types of catheter used for ISC implies that Japanese reusable catheters have the potential to benefit selected persons with SCL. Further research is warranted to develop measures for maximizing work productivity by overcoming urinary as well as bowel problems.

Bladder irrigation with tap water to reduce antibiotic use for urinary tract infections in catheter users.

To evaluate the safety and effectiveness of bladder irrigation (BI) with tap water to reduce antibiotic use for the treatment of urinary tract infections (UTIs) in patients with recurrent UTI symptoms and to assess the treatment satisfaction of BI. This prospective, observational study included patients with an indwelling catheter or performing clean intermittent catheterisation (CIC) who had recurrent UTI symptoms between July 2022 and March 2024. BI with tap water was used for the treatment of UTIs without systemic symptoms (e.g., fever, flank pain or delirium). Patients started daily irrigation at the onset of UTI symptoms and used a tapering schedule. The number of antibiotic treatments for UTIs, UTI incidence rate ratio (IRR), UTI-related hospitalisations, treatment satisfaction and quality of life (QoL) were compared between a 3-month period before and after BI with tap water. A total of 60 patients were included with a median (interquartile range) age of 64.5 (50.4-72.6) years, 66.7% were male, and 83.3% were performing CIC. Antibiotic use was decreased on average by 38.1% (IRR = 0.62; P = 0.016) and catheter-associated UTIs by 37.9% (IRR = 0.62; P = 0.005). No increase was observed in the incidence of UTIs with systemic symptoms or UTI-related hospitalisations. In addition, no differences were observed in the health-related QoL. The majority of patients were positive about the subjective effectiveness (81%), ease of use (86%) and overall satisfaction (85%) of BI with tap water. These findings emphasise the potential of BI with tap water as a promising and patient-friendly alternative for the treatment of UTIs in patients with urinary catheters. BI with tap water significantly reduces antibiotic use and UTI incidence in patients with recurrent UTIs and is a safe and patient-friendly alternative that can be easily implemented in the management of UTIs.

Treatment of urinary disorders in patients with multiple sclerosis: A review

Voiding disorders are one of the most common clinical manifestations of multiple sclerosis, significantly worsening the quality of life of patients. The review article provides information about the nature and symptoms of lower urinary tract dysfunctions, the reasons for their development and possible complications. The general principles of treatment of urinary disorders in patients with multiple sclerosis are presented, as well as features of the treatment of detrusor overactivity, detrusor-sphincter dyssynergia and detrusor hypoactivity. The possibilities of non-drug and drug therapy, botulinum therapy, and neuromodulation are described in detail. The role of intermittent catheterization in the treatment of patients with impaired evacuation function of the bladder is shown. Practical issues of choosing a treatment method depending on the clinical situation are considered.

An Alternative Approach for Treating Female Underactive Bladders with Chronic Urine Retention: A Pilot Study on Combined Transvaginal Ultrasound-Guided Botulinum Toxin A External Sphincter Injection and Transurethral Incision of the Bladder Neck.

Background: Treating an underactive bladder (UAB) is challenging. Previously, we introduced a more precise method of transvaginal ultrasound-guided botulinum toxin A (BoNT-A) injection into the external urethral sphincter as a treatment option for patients with UABs. Although many patients experience good results, those with an UAB and excessive residual urine still require catheterization. Therefore, we developed a new method that combines transvaginal ultrasound-guided BoNT-A injection with a transurethral bladder neck incision. Methods: A prospective study was conducted on 16 patients who experienced symptoms of UAB and chronic urine retention. The treatment consisted of a combination of transvaginal ultrasound-guided BoNT-A injection and a transurethral incision of the bladder neck (TUI-BN). The primary objective was to assess the efficacy of this combined treatment in improving symptoms in women with UABs. Results: Our study demonstrated significant improvements after treatment, including increased voiding volume, decreased post-void residual (PVR) urine, and improved voiding efficiency. The frequency of clean intermittent catheterization (CIC) decreased at 1 and 3 months post-surgery, along with improvements in the AUA symptoms score and the Patient Perception of Bladder Condition (PPBC) score. Conclusions: Our study showed significant improvements in the surgical treatment of UABs using a combination of transvaginal ultrasound-guided BoNT-A and TUI-BN.

The relationship between uropathogens and clinical characteristics of children with urinary tract infection

Urinary tract infections (UTI) are common bacterial infections in children. This study aimed to examine the relationships between different microorganisms and both clinical and laboratory findings in pediatric patients with UTIs. We conducted a retrospective evaluation of children with UTI between 2019 and 2024. Patients were divided into four main groups as normal anatomy, vesicoureteral reflux (VUR), ureteropelvic junction obstruction (UPJO), and neurogenic bladder (NB). Information on clean intermittent catheterization (CIC) and prophylactic antibiotic use was recorded. Laboratory results were compared across these patient groups. The study included 266 patients, with a female predominance (female/male ratio: 7.33). NB was the most common urinary tract condition (43.3%), followed by VUR (10.9%) and UPJO (9%). Prophylactic antibiotics were used by 9% of the patients. Acute phase reactants in patients with CIC were significantly higher (p=0.023 for white blood cell (WBC) and p=0.002 for C-reactive protein (CRP) levels). They were also higher in patients with prophylactic antibiotics compared to those without (p=0.001 for both). The most frequently detected bacteria in urine cultures were E. coli (65%), followed by Klebsiella spp. (18.8%), Pseudomonas spp. (7.5%), and Proteus spp. (4.9%). Klebsiella spp., Enterococcus spp., and Morganella spp. were not isolated from patients receiving prophylaxis (p=0.022). Risk factors for UTIs need to be carefully assessed for every patient, and treatment should be customized according to clinical and laboratory results. Individual patient factors should guide drug selection, and treatment plans should account for potential resistance patterns.

Particularities of spasticity in myelomeningocele patients.

Myelomeningocele (MMC), a congenital neural tube defect, is the most common developmental anomaly of the central nervous system (CNS). Spasticity is among the main disabling factors in these patients, affecting up to 1/5 of children. The purpose of this article is to review the current knowledge regarding spasticity in MMC patients, mainly focusing on its manifestations and management. A literature search was conducted using the PubMed database for the terms "myelomeningocele" and "spasticity." Data were collected by 5 independent investigators and then synthesized in a scoping format. Causes of spasticity in these patients include hydrocephalus, tethered cord syndrome (TCS), syringomyelia, CNS infection, and associated congenital brain and spine anomalies. Clinical manifestations include limb spasticity and neurogenic bladder. Spasticity primarily affects muscles below the neurological level and contributes to gait impairment. Besides walking ability, spasticity also severely affects functional mobility in general, self-care, and quality of life. The majority of MMC patients experience neurogenic bladder. Treatment of spasticity can be symptomatic or target its cause. Medical and surgical options are available for both limb and bladder spasticity. Regular physiotherapy and orthotics are used to prevent contractures and the early introduction of orthoses is the cornerstone of a gait training program. Neurosurgical treatment options for spasticity include nonablative and ablative procedures such as selective dorsal rhizototmy. The urodynamic pattern guides treatment strategies, with intermittent catheterization being the best treatment option for patients with underactive detrusor and overactive sphincter muscles. Given the particularities of spasticity in MMC patients, a multidisciplinary team approach and early rehabilitation programs are keys for their optimal management.

Thermo-expandable intraprostatic nitinol stents in the treatment of bladder outlet obstruction: a consecutive case series.

In high-risk patients, prostatic stents may alleviate obstruction at the prostate level. Since 2020 we have used thermo-expandable intraprostatic nitinol stents. Here we document outcomes through the first years with the procedure. We reviewed patients who had undergone stent treatment between May 2020 and October 2023. Patient and procedural data, urinary symptoms, complications and side effects were recorded. Descriptive statistics were used to summarize outcomes and we evaluated predictors of success and complications using robust multiple regression analyses. We included 52 consecutive patients with a median age of 82 years (range 71-96) and a median Charlson Comorbidity Index of 6 (3-11). Forty-seven men used indwelling catheters, two used clean intermittent catheterization, and three had severe lower urinary tract symptoms. Stents were placed under general anesthesia, sedation, and local anesthesia in 39, 4, and 9 men, respectively. The median treatment time was 14 min (range 8-40). One complication, in the form of an infection requiring IV antibiotics, occurred. Subsequently, 45 men (87%) were able to void spontaneously without bothersome symptoms. After a median of 11 (2-44) months, 8 men had their stents removed due to recurring symptoms. This gives an overall success rate of 37/52 patients (71%). No predictors of success or complications were identified. Thermo-expandable intraprostatic nitinol stents demonstrate a high success rate with a low risk of complications and may serve as an alternative to permanent or intermittent catheterization for men who are unable or unwilling to undergo flow-improving surgery.

Experiences and barriers with home bladder manometry in the pediatric neurogenic bladder population: A qualitative study

Patients with neurogenic bladder are at risk of developing renal deterioration secondary to increased intravesical pressures. To date, urodynamics is the gold standard test to properly assess bladder dynamics. Home bladder manometry is a low-cost and simple method to evaluate bladder pressures and volumes during clean intermittent catheterization (CIC). Previous literature has shown that home manometry measurements correlate with urodynamic pressures and hydronephrosis on ultrasound. However, no studies have evaluated the challenges and barriers faced by caregivers with the process. Our objective was to investigate the experiences and perceptions of caregivers, healthcare providers, and nurses with home manometry. We conducted semi-structured interviews and focus group discussions with 23 stakeholders. Stakeholders included caregivers of pediatric spina bifida neurogenic bladder patients, providers, and nursing staff. Grounded Theory Methods were used to analyze transcripts and identify preliminary concepts that described attitudes towards the current home bladder manometry process. Interview participants were composed of 10 (43%) caregivers, 9 (40%) healthcare providers, and 4 (17%) nursing staff. The mean age was 39 years (range 26-66). The four themes identified during discussions were perspectives on home manometry, patient-specific characteristics, challenges with home manometry, and learning experience. All caregivers expressed understanding and agreement with the purpose and importance of home manometry. Emergent concepts identified as targets for improvement were the need for standardization of teaching processes with focus on hands-on practice, understanding of patient characteristics and the home environment that make the process more challenging, and the need for appropriate materials including extension tubing and catheters. Home bladder manometry is a feasible and beneficial way for neurogenic bladder patients to monitor their bladder pressures and volumes at home. This qualitative study offers valuable insights into the experiences and viewpoints of caregivers, healthcare providers, and nurses regarding both home manometry and the general experience with CIC.

Clean intermittent catheterisation determinants and caregiver adherence in paediatric patients with spinal dysraphism and spinal cord injury in a paediatric spinal differences clinic: a mixed methods study protocol

An Evaluation of the Postvoid Residual Urine Volume in Acute Stroke Patients.

We analyzed the time course of postvoid residual urine volume for patients with cerebrovascular diseases in the acute phase. A multidisciplinary specialized team measured postvoid residual urine volume of 65 patients (31 patients with cerebral infarction and 34 patients with cerebral hemorrhage) from September 2021 to August 2023. If a patient's postvoid residual urine volume was 100 mL or more, an indwelling urinary catheter was reinserted with or without medication, or clean intermittent catheterization was performed with or without medication. The multidisciplinary specialized team took repeated measurements of postvoid residual urine volume for a patient at every week's round until the postvoid residual urine volume was <100 mL. The cumulative incidence of the time interval between the onset of the cerebrovascular accident and the day of postvoid residual urine volume <100 mL was calculated as 1 + the Kaplan-Meier estimator. In the Kaplan-Meier estimator, the median cumulative incidence of the period between the onset of a cerebrovascular accident and the day in which postvoid residual urine volume was <100 mL was 16.5 days and 15.5 days for patients with cerebral infarction and cerebral hemorrhage, respectively. No significant difference existed between the two groups in the time interval from the onset of a cerebrovascular accident to the day in which postvoid residual urine volume was <100 mL (The P value from the Log-rank test was 0.845). The time interval between the onset of a cerebrovascular accident and the day in which postvoid residual urine volume was <100 mL was 75 days after the onset of both types of cerebrovascular accidents. Postvoid residual urine volume of patients with cerebrovascular disease was expected to become <100 mL within 75 days after the onset of the cerebrovascular accident.

Suprapubic vesicostomy buttons: Indications, complications and bladder outcomes

IntroductionVesicostomy button drainage is a recognised alternative to clean intermittent catheterization (CIC) in children with urethral obstruction, sensate urethra or neurological/ behavioural issues. AimTo report the indications, complications and long-term bladder functional outcomes in a 15-year cohort of patients with button vesicostomy. Materials and MethodsAMT Mini one gastrostomy buttonR was inserted via a surgical vesicostomy, or percutaneously under cystoscopic guidance. Retrospective data included demographics, indications, complications, and long-term bladder capacity/ emptying pre-post-button removal. Results29 children (23 males) underwent vesicostomy button insertion at 3.5 (0.5-14.5) years. Diagnosis was neurogenic (11), bladder outlet obstruction (9), cloaca/urogenital sinus (3), anorectal malformation (ARM) (2), other bladder dysfunction (3) and diversion (1). There were no short-term complications. UTI occurred in 31%, leakage in 28% and blockage in 7%. At a median of 10 (2-18) years, 14 (48%) are still on button drainage; 6 (21%) progressed to Mitrofanoff catheterisation. In 9 (31%) who no longer require the button, all children were able to void urethrally, with good emptying, at 4.5 (1- 7) years follow-up. DiscussionContinent vesicostomy allows toilet-training and improved quality of life. We estimated that the cost of a button vesicostomy and tubing approximates £1502 per year. 5-6 Speedicaths per day (costing £38 per pack) cost £2772 per year. Asymptomatic bacterial colonisation does not require antibiotic treatment; it is best avoided by changing the button every 12 weeks. Symptomatic febrile UTI’s are commonly secondary to the underlying pathology; we recommend changing the button half-way through the antibiotic treatment course. Leakage was managed by increasing the water in the balloon. Button blockage, commonly due to balloon encrustation, is preventable by regular button changes.Button drainage may be temporary (until bladder dysfunction resolves, or changed to a Mitrofanoff), or a long-term (in life-long neuro-developmental/ behavioural issues). The button was no longer required in 9: bladder function improved post spinal cord un-tethering in 3; 2 PUV; 2 ARM; 1 myopathy and 1 diversion. Of note, the button did not appear to affect bladder dynamics with sustained resolution of bladder dysfunction in 31%.Our main limitation was diversity of pathologies, making comparison of urodynamics more challenging: a larger study with more numbers in each patient group would be the next step. ConclusionSuprapubic buttons are a safe second-line bladder drainage option in patients who are unable to CIC. The technique may be a temporary solution where bladder dysfunction may resolve, or until the child is ready for catheterisation via a Mitrofanoff.
