Prevention and treatment of urinary incontinence after stroke in adults

Urinary dysfunction in patients with vascular cognitive impairment

Vascular cognitive impairment (VCI) is caused by vascular pathologies, with the spectrum of cognitive disorders ranging from subjective cognitive dysfunction to dementia. Particularly among older adults, cognitive impairment is often complicated with urinary dysfunction (UD); some patients may present with UD before cognitive impairment owing to stroke or even when there are white matter hyperintensities on imaging studies. Patients with cognitive impairment often have both language and movement dysfunction, and thus, UD in patients with VCI can often be underdiagnosed and remain untreated. UD has an impact on the quality of life of patients and caregivers, often leading to poor outcomes. Medical history is an important aspect and should be taken from both patients and their caregivers. Clinical assessment including urinalysis, voiding diary, scales on UD and cognitive impairment, post-void residual volume measurement, uroflowmetry, and (video-) urodynamics should be performed according to indication. Although studies on UD with VCI are few, most of them show that an overactive bladder (OAB) is the most common UD type, and urinary incontinence is the most common symptom. Normal urine storage and micturition in a specific environment are complex processes that require a sophisticated neural network. Although there are many studies on the brain-urinary circuit, the specific circuit involving VCI and UD remains unclear. Currently, there is no disease-modifying pharmacological treatment for cognitive impairment, and anti-acetylcholine drugs, which are commonly used to treat OAB, may cause cognitive impairment, leading to a vicious circle. Therefore, it is important to understand the complex interaction between UD and VCI and formulate individualized treatment plans. This review provides an overview of research advances in clinical features, imaging and pathological characteristics, and treatment options of UD in patients with VCI to increase subject awareness, facilitate research, and improve diagnosis and treatment rates.

Acupuncture as a post-stroke treatment option: A narrative review of clinical guideline recommendations

BACKGROUND

Acupuncture may be useful to treat the various clusters of symptoms occurring after a stroke. The use of evidence to underpin clinical practice and treatment guidelines (CPGs and TGs respectively) varies from country to country and may affect what recommendations are made by guideline developers.

PURPOSE

To examine the extent to which international clinical and treatment guidelines on post-stroke treatment mention the role of acupuncture and to identify what symptoms they recommend for its use.

METHOD

Scoping of national and international websites of CPGs and TGs r on the after care and rehabilitation of stroke patients provided by professional and government organisations was conducted. The presence/absence of recommendations and the underpinning evidence was appraised for the use of acupuncture for symptoms following stroke.

RESULTS

Of 84 CPGs and TGs on post stroke after-care identified from 27 countries between 2001 and 2021, 49 made statements about acupuncture. Positive recommendations on the use of acupuncture were identified for 15 symptom areas from 11 countries for: stroke rehabilitation, dysphagia, shoulder pain, motor recovery, walking, balance, spasticity, upper limb extremity impairment, post-stroke pain, central post stroke pain, cognitive disorder, depression, and sleep problems. Thirty-five CPGs (2001-2018) from 18 countries published over the same period were identified that made no mention of acupuncture and therefore no recommendations were made on its use.

CONCLUSIONS

Currently, evidence used by international guideline developers varies and this influences whether a positive or negative recommendation is made. Recommendations to use acupuncture should be based on the best available evidence which has been quality appraised.

The Brain and the Bladder: Forebrain Control of Urinary (In)Continence

Neural circuits extending from the cerebral cortex to the bladder maintain urinary continence and allow voiding when it is socially appropriate. Injuries to certain brain regions produce a specific disruption known as urge incontinence. This neurologic symptom is distinguished by bladder spasticity, with sudden urges to void and frequent inability to maintain continence. The precise localization of neural circuit disruptions responsible for urge incontinence remains poorly defined, partly because the brain regions, cell types, and circuit connections that normally maintain continence are unknown. Here, we review what is known about the micturition reflex circuit and about forebrain control of continence from experimental animal studies and human lesion data. Based on this information, we hypothesize that urge incontinence results from damage to a descending pathway that normally maintains urinary continence. This pathway begins with excitatory neurons in the prefrontal cortex and relays subcortically, through inhibitory neurons that may help suppress reflex micturition during sleep and until it is safe and socially appropriate to void. Identifying the specific cell types and circuit connections that constitute the continence-promoting pathway, from the forebrain to the brainstem, will help us better understand why some brain lesions and neurodegenerative diseases disrupt continence. This information is needed to pave the way toward better treatments for neurologic patients suffering from urge incontinence.

Interventions for treating urinary incontinence after stroke in adults

BACKGROUND

Urinary incontinence can affect 40% to 60% of people admitted to hospital after a stroke, with 25% still having problems when discharged from hospital and 15% remaining incontinent after one year.This is an update of a review published in 2005 and updated in 2008.

OBJECTIVES

To assess the effects of interventions for treating urinary incontinence after stroke in adults at least one-month post-stroke.

SEARCH METHODS

We searched the Cochrane Incontinence and Cochrane Stroke Specialised Registers (searched 30 October 2017 and 1 November 2017 respectively), which contain trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP and handsearched journals and conference proceedings.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials.

DATA COLLECTION AND ANALYSIS

Two review authors independently undertook data extraction, risk of bias assessment and implemented GRADE.

MAIN RESULTS

We included 20 trials (reporting 21 comparisons) with 1338 participants. Data for prespecified outcomes were not available except where reported below.Intervention versus no intervention/usual careBehavioural interventions: Low-quality evidence suggests behavioural interventions may reduce the mean number of incontinent episodes in 24 hours (mean difference (MD) -1.00, 95% confidence interval (CI) -2.74 to 0.74; 1 trial; 18 participants; P = 0.26). Further, low-quality evidence from two trials suggests that behavioural interventions may make little or no difference to quality of life (SMD -0.99, 95% CI -2.83 to 0.86; 55 participants).Specialised professional input interventions: One trial of moderate-quality suggested structured assessment and management by continence nurse practitioners probably made little or no difference to the number of people continent three months after treatment (risk ratio (RR) 1.28, 95% CI 0.81 to 2.02; 121 participants; equivalent to an increase from 354 to 453 per 1000, 95% CI 287 to 715).Complementary therapy: Five trials assessed complementary therapy using traditional acupuncture, electroacupuncture and ginger-salt-partitioned moxibustion plus routine acupuncture. Low-quality evidence from five trials suggested that complementary therapy may increase the number of participants continent after treatment; participants in the treatment group were three times more likely to be continent (RR 2.82, 95% CI 1.57 to 5.07; 524 participants; equivalent to an increase from 193 to 544 per 1000, 95% CI 303 to 978). Adverse events were reported narratively in one study of electroacupuncture, reporting on bruising and postacupuncture abdominal pain in the intervention group.Physical therapy: Two trials reporting three comparisons suggest that physical therapy using transcutaneous electrical nerve stimulation (TENS) may reduce the mean number of incontinent episodes in 24 hours (MD -4.76, 95% CI -8.10 to -1.41; 142 participants; low-quality evidence). One trial of TENS reporting two comparisons found that the intervention probably improves overall functional ability (MD 8.97, 95% CI 1.27 to 16.68; 81 participants; moderate-quality evidence).Intervention versus placeboPhysical therapy: One trial of physical therapy suggests TPTNS may make little or no difference to the number of participants continent after treatment (RR 0.75, 95% CI 0.19 to 3.04; 54 participants) or number of incontinent episodes (MD -1.10, 95% CI -3.99 to 1.79; 39 participants). One trial suggested improvement in the TPTNS group at 26-weeks (OR 0.04, 95% CI 0.004 to 0.41) but there was no evidence of a difference in perceived bladder condition at six weeks (OR 2.33, 95% CI 0.63 to 8.65) or 12 weeks (OR 1.22, 95% CI 0.29 to 5.17). Data from one trial provided no evidence that TPTNS made a difference to quality of life measured with the ICIQLUTSqol (MD 3.90, 95% CI -4.25 to 12.05; 30 participants). Minor adverse events, such as minor skin irritation and ankle cramping, were reported in one study.Pharmacotherapy interventions: There was no evidence from one study that oestrogen therapy made a difference to the mean number of incontinent episodes per week in mild incontinence (paired samples, MD -1.71, 95% CI -3.51 to 0.09) or severe incontinence (paired samples, MD -6.40, 95% CI -9.47 to -3.33). One study reported no adverse events.Specific intervention versus another interventionBehavioural interventions: One trial comparing a behavioural intervention (timed voiding) with a pharmacotherapy intervention (oxybutynin) contained no useable data.Complementary therapy: One trial comparing different acupuncture needles and depth of needle insertion to assess the effect on incontinence reported that, after four courses of treatment, 78.1% participants in the elongated needle group had no incontinent episodes versus 40% in the filiform needle group (57 participants). This trial was assessed as unclear or high for all types of bias apart from incomplete outcome data.Combined intervention versus single interventionOne trial compared a combined intervention (sensory motor biofeedback plus timed prompted voiding) against a single intervention (timed voiding). The combined intervention may make little or no difference to the number of participants continent after treatment (RR 0.55, 95% CI 0.06 to 5.21; 23 participants; equivalent to a decrease from 167 to 92 per 1000, 95% CI 10 to 868) or to the number of incontinent episodes (MD 2.20, 95% CI 0.12 to 4.28; 23 participants).Specific intervention versus attention controlPhysical therapy interventions: One study found TPTNS may make little or no difference to the number of participants continent after treatment compared to an attention control group undertaking stretching exercises (RR 1.33, 95% CI 0.38 to 4.72; 24 participants; equivalent to an increase from 250 to 333 per 1000, 95% CI 95 to 1000).

AUTHORS' CONCLUSIONS

There is insufficient evidence to guide continence care of adults in the rehabilitative phase after stroke. As few trials tested the same intervention, conclusions are drawn from few, usually small, trials. CIs were wide, making it difficult to ascertain if there were clinically important differences. Only four trials had adequate allocation concealment and many were limited by poor reporting, making it impossible to judge the extent to which they were prone to bias. More appropriately powered, multicentre trials of interventions are required to provide robust evidence for interventions to improve urinary incontinence after stroke.

Lower urinary tract dysfunction in patients with brain lesions

Stroke and brain tumor are well-known brain diseases. The incidence of lower urinary tract dysfunction (LUTD) in these patients ranges from 14% to 53%, mostly overactive bladder (OAB), and is higher when the frontal cortex is involved. This presumably reflects damage at the prefrontal cortex, cingulate cortex, and other areas that regulate (mainly inhibit) the micturition reflex. White-matter disease (WMD) is a chronic, bilateral form of cerebrovascular disease, leading to a high prevalence of OAB (up to 90%). Since WMD is particularly common in the elderly, WMD may be one of the anatomic substrates for elderly OAB. Traumatic brain injury and normal-pressure hydrocephalus are rather diffuse brain diseases, which cause OAB with a prevalence rate of 60-95%. Recent neuroimaging studies have shown a relationship between LUTD and the frontal cortex in these diseases. Data on other brain diseases, particularly affecting deep brain structures, are limited. Small infarctions, tumors, or inflammatory diseases affecting the basal ganglia, hypothalamus, and cerebellum lead to mainly OAB. In contrast, similar diseases affecting the brainstem lead to either OAB or urinary retention. The latter reflects damage at the periaqueductal gray and the pontine micturition center that directly relay and modulate the micturition reflex. Urinary incontinence (UI) in brain disease can be divided into two types: neurogenic UI (due to OAB) and functional UI (immobility and loss of initiative/cognition). These two types of UI may occur together, but management differs significantly. Management of neurogenic UI includes anticholinergic drugs that do not penetrate the blood-brain barrier easily. Management of functional UI includes behavioral therapy (timed/prompted voiding with physical assistance and bladder/pelvic floor training) and drugs to treat gait as well as cognition that facilitate continence. These treatments will maximize the quality of life in patients with brain diseases.

Development and evaluation of tools and an intervention to improve patient- and carer-centred outcomes in Longer-Term Stroke care and exploration of adjustment post stroke: the LoTS care research programme

Background

Evidence-based care pathways are required to support stroke patients and their carers in the longer term.

Aims

The twofold aim of this programme of four interlinking projects was to enhance the care of stroke survivors and their carers in the first year after stroke and gain insights into the process of adjustment.

Methods and results

We updated and further refined a purposely developed system of care (project 1) predicated on a patient-centred structured assessment designed to address areas of importance to patients and carers. The structured assessment is linked to evidence-based treatment algorithms, which we updated using a structured protocol: reviewing available guidelines, Cochrane reviews and randomised trials. A pragmatic cluster randomised controlled trial evaluation of the clinical effectiveness and cost-effectiveness of this system of care was undertaken in 29 community-based UK stroke care co-ordinator services (project 2). In total, 15 services provided the system of care and 14 continued with usual practice. The primary objective was to determine whether the intervention improved patient psychological outcomes (General Health Questionnaire-12) at 6 months; secondary objectives included functional outcomes for patients, outcomes for carers and cost-effectiveness, as measured through self-completed postal questionnaires at 6 and 12 months. A total of 800 patients and 208 carers were recruited; numbers of participants and their baseline characteristics were well balanced between intervention and control services. There was no evidence of statistically significant differences in primary or secondary end points or adverse events between the two groups, nor evidence of cost-effectiveness. Intervention compliance was high, indicating that this is an appropriate approach to implement evidence into clinical practice. A 22-item Longer-term Unmet Needs after Stroke (LUNS) questionnaire was developed and robustly tested (project 3). A pack including the LUNS questionnaire and outcome assessments of mood and social activity was posted to participants 3 or 6 months after stroke to assess acceptability and validity. The LUNS questionnaire was re-sent 1 week after return of the first pack to assess test–retest reliability. In total, 850 patients were recruited and the acceptability, validity and test–retest reliability of the LUNS questionnaire as a screening tool for post-stroke unmet need were confirmed. This tool is now available for clinical use. An in-depth qualitative investigation was undertaken with 22 patients (and carers) at least 1 year after stroke (project 4) to gain further insights into the experience of adjustment. This included initial semistructured interviews, limited observations and solicited diaries with a follow-up interview 3–4 months after the initial interview and highlighted a range of different trajectories for post-stroke recovery.

Conclusions

The programme has been completed as planned, including one of the largest ever stroke rehabilitation trials. This work highlights that successfully addressing the needs of a heterogeneous post-stroke population remains problematic. Future work could explore stratifying patients and targeting services towards patients (and carers) with specific needs, leading to a more specialised bespoke service. The newly developed LUNS questionnaire and the qualitative work will help inform such services.

Efficacy and safety of ginger-salt-indirect moxibustion for urge urinary incontinence after stroke: protocol for a pilot multicentre randomised controlled trial

INTRODUCTION

Ginger-salt-indirect moxibustion is widely applied to treat urge urinary incontinence after stroke, which is a common complication in stroke survivors. Moxa cone moxibustion and moxa box moxibustion are the main techniques of ginger-salt-indirect moxibustion. Our previous study had shown that ginger-salt-indirect moxibustion using moxa cones was feasible and effective for urination disorders post-stroke. This pilot study aims to assess the feasibility of conducting research to evaluate the efficacy and safety of ginger-salt-indirect moxibustion for patients with post-stroke urge urinary incontinence.

METHODS AND ANALYSIS

This is a multicentre, prospective, single-blinded, pilot randomised controlled trial. 120 eligible patients will be randomly allocated to three groups. Treatment group A (n=40) will receive moxa cone moxibustion and routine care; treatment group B (n=40) will receive moxa box moxibustion and routine care; control group (n=40) will only receive routine care for stroke recovery. The entire moxibustion treatment will consist of a total of 28 sessions during the course of 4 weeks. The primary outcome measure will be the increase in mean volume per void assessed at week 4 from the first moxibustion session (baseline). Secondary outcome measures will include mean frequency of urination per day and quality of life assessments measured by completion of the Incontinence Quality of Life Questionnaire and Barthel Index. All outcome measures will be assessed at baseline and at 4 and 16 weeks from baseline. Adverse events in the three groups will be recorded to assess the safety of moxibustion.

ETHICS AND DISSEMINATION

Research ethics was approved by the Research Ethical Committee of Beijing Hospital of Traditional Chinese Medicine Affiliated to the Capital Medical University (ref: 2013BL-094). Written informed consent will be obtained from all participants. Study results will be published in peer reviewed journals.

Guidelines for management of ischaemic stroke and transient ischaemic attack 2008

This article represents the update of the European Stroke Initiative Recommendations for Stroke Management. These guidelines cover both ischaemic stroke and transient ischaemic attacks, which are now considered to be a single entity. The article covers referral and emergency management, Stroke Unit service, diagnostics, primary and secondary prevention, general stroke treatment, specific treatment including acute management, management of complications, and rehabilitation.

Chapitre J - Troubles vésico-sphintériens des accidents vasculaires cérébraux

Lower urinary tract dysfunction is very frequent during the acute phase of stroke. In the majority of cases, it resolves over the months following the acute neurological event. A review of the literature does not identify any chronic urinary disorders specific to post-stroke, except in very particular cases (spinal cord infarction, frontal stroke, etc.). However, there appears to be a high incidence of nonspecific voiding disorders, such as urinary incontinence related to urgency-frequency syndrome or nocturia. In particular these disorders complicate the management of lower urinary tract obstructive disorders in these frail patients. Urologists must be familiar with these disorders in order to evaluate these patients particularly carefully before proposing treatments, especially surgery, which appears to achieve much less favourable results, especially functional results, than in the general population.

Is there a long-lasting effect of pelvic floor muscle training in women with urinary incontinence after ischemic stroke? A 6-month follow-up study

The aim of this study was to evaluate the long-lasting effect of pelvic floor muscle training (PFMT) in women with urinary incontinence after stroke measured by quality of life parameters. Twenty-four (24/24) women with urinary incontinence after stroke, who had completed a prospective, randomised controlled and single-blinded trial evaluating the effect of 12 weeks PFMT, were included in this follow-up study. The follow-up assessments were done by telephone interview 6 months after the intervention. The effect was evaluated by The Short Form 36 (SF-36) Health Survey Questionnaire and Incontinence Impact Questionnaire (IIQ). Twenty-four subjects completed the study. In the treatment group, the SF-36 showed a trend to a long-lasting effect in one of the eight domains and the IIQ showed a tendency to decreased impact of UI in two sub-scales compared to the control group. Our data indicated that PFMT may have a long-lasting effect measured by quality of life parameters.
