Abstract
BACKGROUND Spina bifida is a type of a neural tube defect which affects 243.14 per 100,000 babies in Asia. Research articles on spina bifida have increased in the recent years. However, no study has focused on the research trends in this field in Asia. METHODS A systematic review of literature on spina bifida in Asia was performed using the Scopus database from inception to 2020. All published studies on spina bifida conducted in or published by authors from Asia were included in our analysis. Bibliometric information was obtained from Scopus and bibliometrics diagrams were created using VOSviewer software. RESULTS A total of 652 articles were obtained in this study. The number of publications showed an upward trend starting 2000s. The country with the greatest number of publications was Japan while All India Institute of Medical Sciences was the most productive institution in spina bifida research in Asia. The current focus of this field in Asia was prevalence of spina bifida, prenatal diagnosis, folic acid supplementation, and complications of spina bifida. Future areas of research in spina bifida include the genetic basis of neural tube defects and the use of stem cell technology as therapies for spina bifida. CONCLUSION This is the first bibliometric analysis on spina bifida in Asia. It showed the trend and future areas of research on spina bifida in Asia. Despite the increase in scientific literature on spina bifida research, more research outputs and collaborations are needed especially in developing countries in Asia.

Abstract
BACKGROUND Children and young people with neurodisability often need help to achieve socially acceptable bladder and bowel control. Approaches vary depending on whether or not the impairment results from spinal cord pathology that impairs motor control and sensation of the bladder and bowel. Currently, there is uncertainty about which interventions are effective. OBJECTIVE The objective was to summarise the available evidence on and current practice for improving continence in children and young people with neurodisability. DESIGN A systematic review of the effectiveness, cost-effectiveness and factors that modify intervention implementation, alongside a cross-sectional, online survey of current practice with health professionals, parent carers, school and care staff and young people with neurodisability. RESULTS Twelve databases were searched in the review, resulting in 5756 references; 71 studies (72 papers) were included in the analyses. Most of the evidence was for children with spinal cord pathology, which involved evaluations of pharmacological approaches and surgical techniques, whereas the evidence pertaining to those with non-spinal-cord-related pathology tended to be for behavioural interventions. The methodological quality of studies was rated as being moderate to poor. There were three robust qualitative studies about the experience of continence among children with spinal cord pathology. We found substantial heterogeneity across the interventions that we evaluated in terms of quality, study design and outcomes measured. No economic studies were found. The results were synthesised narratively and reported in text and tables. We did not find any eligible studies evaluating interventions using toilet and clothing adaptations in the review, although the survey highlighted that these types of interventions are frequently used and considered. In total, 949 people responded to the survey: 202 health professionals, 605 parent carers, 122 school and social care staff, and 20 young people. The survey results illustrated the different roles that professionals have in improving continence, highlighting the importance of a multidisciplinary approach to supporting children and young people and their families. Clinicians employ a range of assessments and interventions to improve continence or independent toileting, depending on the needs of the child. LIMITATIONS Quantitative studies in the review were not methodologically robust. The survey had a risk of response bias. CONCLUSIONS Our research found a dearth of good-quality evidence for many of the interventions currently in use, and no evidence of experiences of implementing interventions for children with non-spinal-cord-related pathology. There was also no evidence of cost-effectiveness of any of the interventions. FUTURE WORK There is a need to involve young people and families in the design of high-quality evaluative research for interventions that aim to improve continence. This is especially the case for children with autism and learning disability, who have been neglected in previous evaluative and qualitative research. We recommend better training for health, education and care professionals about toileting, informed by evidence and the lived experiences of children and their families. We recommend a joined-up multidisciplinary and holistic approach to improving continence to maximise independence, dignity and comfort. It is vital that children and young people with neurodisability have early access to regular, integrated assessment of their bladder and bowel health, and are fully supported with appropriate personalised treatment.

Abstract
Neurogenic/neuropathic bowel dysfunction (NBD) is common in children who are affected by congenital and acquired neurological disease, and negatively impacts quality of life. In the past, NBD received less attention than neurogenic bladder, generally being considered only in spina bifida (the most common cause of pediatric NBD). Many methods of conservative and medical management of NBD are reported, including relatively recently Transanal Irrigation (TAI). Based on the literature and personal experience, an expert group (pediatric urologists/surgeons/gastroenterologists with specific experience in NBD) focused on NBD in children and adolescents. A statement document was created using a modified Delphi method. The range of causes of pediatric NBD are discussed in this paper. The various therapeutic approaches are presented to improve clinical management. The population of children and adolescents with NBD is increasing, due both to the higher survival rate and better diagnosis. While NBD is relatively predictable in producing either constipation or fecal incontinence, or both, its various effects on each patient will depend on a wide range of underlying causes and accompanying comorbidities. For this reason, management of NBD should be tailored individually with a combined multidisciplinary therapy appropriate for the status of the affected child and caregivers.

Abstract
AIMS Mounting evidence from experimental animal and human studies suggests that cross-sensitization exists between different organs. Lower urinary tract (LUT) and bowel dysfunction commonly overlap, and the role of cross-sensitization between pelvic visceral organs is uncertain. METHODS At the International Consultation on Incontinence Research Society (ICI-RS) meeting in 2018, a panel of clinicians participated in a discussion on bladder and bowel interactions in the context of pelvic organ cross-sensitization. RESULTS Bladder and bowel problems commonly co-occur in adults and children across different disorders, and the mechanism responsible for overlapping dysfunction is uncertain in most instances. At a neuronal level, cross-sensitization occurs as a result of afferent signaling from the LUT and lower bowel through different central and peripheral mechanisms. Studies in animals and humans have demonstrated evidence for cross-organ sensitization following experimental inflammation or distension of the lower bowel, affecting the LUT. Nerve stimulation is an effective treatment for different functional LUT and bowel disorders, and whether this treatment may influence cross-organ sensitization remains uncertain. The role of physiologically dormant C-fibers, the bladder-gut-brain axis, and gut microbiome in cross-sensitization are speculative. CONCLUSION Recommendations for research were made to explore the role of cross-organ sensitization in the pathogenesis of co-occurring LUT and bowel dysfunction in humans.

Abstract
CONTEXT Managing patient and parent expectations regarding urinary and fecal continence is important with congenital conditions that produce neurogenic bladder and bowel dysfunction. Physicians need to be aware of common treatment algorithms and expected outcomes to best counsel these families. OBJECTIVE To systematically evaluate evidence regarding the utilization and success of various modalities in achieving continence, as well as related outcomes, in children with neurogenic bladder and bowel dysfunction. EVIDENCE ACQUISITION We performed a systematic review of the literature in PubMed/Medline in August 2019. A total of 114 publications were included in the analysis, including 49 for bladder management and 65 for bowel management. EVIDENCE SYNTHESIS Children with neurogenic bladder conditions achieved urinary continence 50% of the time, including 44% of children treated with nonsurgical methods and 64% with surgical interventions. Patients with neurogenic bowel problems achieved fecal continence 75% of the time, including 78% of patients treated with nonsurgical methods and 73% with surgical treatment. Surgical complications and need for revisions were high in both categories. CONCLUSIONS Approximately half of children with neurogenic bladder dysfunction will achieve urinary continence and about three-quarters of children with neurogenic bowel dysfunction will become fecally continent. Surgical intervention can be successful in patients refractory to nonsurgical management, but the high complication and revision rates support their use as second-line therapy. This is consistent with guidelines issued by the International Children's Continence Society. PATIENT SUMMARY Approximately half of children with neurogenic bladder dysfunction will achieve urinary continence, and about three-quarters of children with neurogenic bowel dysfunction will become fecally continent. Most children can be managed without surgery. Patients who do not achieve continence with nonsurgical methods frequently have success with operative procedures, but complications and requirements for additional procedures must be expected.

Abstract
Bowel management is a concern in patients with spina bifida. We evaluated the status of bowel management in children with spina bifida (SB) and the effects on quality of life (QoL) of children and their caregivers. Data were collected from 173 children with SB between January and June 2011, whose bowel management status and QoL were assessed using a self-administered questionnaire. Of the 173 children, 38 (22.0%) reported normal defecation, 73 (42.2%) reported constipation only, and 62 (35.8%) reported fecal incontinence with/without constipation. For defecation, 59 children (34.1%) used digital stimulation or manual extraction, 28 (16.2%) used suppositories or enemas, 35 (20.3%) used laxatives, 4 (2.3%) used an antegrade continence enema, and 3 (1.7%) used transanal irrigation. There were significant differences in QoL, depending on defecation symptoms. Children with fecal incontinence and their caregivers had difficulties in travel and socialization (p < .0001), caregivers' emotions (p < .0001), family relationships (p < .0001), and finances (p < .0001). Constipation and fecal incontinence affect QoL of children with SB and their caregivers. Therefore, more attention should be paid to bowel problems and help should be provided to children and their caregivers to improve QoL.

Abstract
BACKGROUND This study aimed to perform a systematic literature review of the clinical trial evidence on electrical stimulation for the treatment of neurogenic bowel dysfunction (NBD) after spinal cord injury (SCI). METHODS Systematic electronic searches were carried out in the PubMed/Medline, EMBASE, Cochrane Central Register of Controlled Trials, and China National Knowledge Infrastructure databases, along with the reference lists in the include studies. Studies were eligible for inclusion if they adopted a controlled clinical design based on human population, the patients suffered from spinal cord injury, the main outcomes were the disorders of bowel function and the intervention was electrical stimulation. Also, the language was limited to English and Chinese. RESULTS Eleven studies were included in this systematic review, comprising transcutaneous electrical stimulation, transrectal bowel stimulation, sacral nerve stimulation, intravesical electrical stimulation, etc. Of the 11 studies, 3 were randomized controlled trials, 8 were controlled before-and-after trials. The quality of the included studies was moderate bias risk. Most studies revealed that the electrical stimulation was beneficial for the patient with NBD after SCI. CONCLUSIONS Only 11 small clinical studies with 298 participants have evaluated the efficacy of electrical stimulation for NBD after SCI. Although some studies showed electrical stimulation was benefit for the patient with NBD after SCI, there was currently not enough evidence to support the use of electrical stimulation could improve the clinical symptoms of those patients. Thus, well-designed randomized controlled trials with larger patient population are warranted to establish its benefit in clinical practice in the future.

Abstract
OBJECTIVE Intravesical electrical stimulation (IVES) has been performed for various purposes in children with a neurogenic bladder. We evaluated the results of IVES on urodynamic study parameters in children with spina bifida. METHODS We retrospectively analyzed the cases of 88 children who received IVES between August 1999 and May 2010 and whose comparative urodynamic data were available before and after treatment. According to the pre-IVES urodynamic study, children were divided into 3 groups: detrusor overactivity, detrusor underactivity and acontractile detrusor. We investigated the changes in detrusor function, bladder capacity and detrusor-sphincter dyssynergia. RESULTS In the group showing detrusor overactivity, the bladder had a synergic pattern in 41.7%, and normal detrusor function was observed in 16.7% of them. Bladder capacity increased after IVES therapy, especially in those who started therapy before 18 months of age (p = 0.019). Detrusor-sphincter dyssynergia was resolved in 55.6%. In the acontractile detrusor group, detrusor contraction ability increased in 48%, but bladder capacity did not. CONCLUSIONS Appropriate candidates for this treatment need to be carefully selected.

Abstract
AIM: To assess the efficacy of electrical stimulation therapy in the treatment of neurogenic bowel dysfunction after spinal injury.
METHODS: PubMed, MEDLINE, EMbase, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Knowledge, OVID, CNKI, VIP, and Wanfang Data were searched for clinical studies that evaluated electrical stimulation therapy for neurogenic bowel dysfunction after spinal injury from the date of creation of databases to October 2012. The bibliographies of the retrieved studies were also searched. Researchers read included studies carefully and extracted data strictly.
RESULTS: A total of 11 studies were included. Electrical stimulation therapies mainly included transcutaneous electrical stimulation, transrectal electrostimulation, intravesical electrical stimulation, and sacral nerve modulation. Electrical stimulation could adjust gut innervation, increase the local blood flow of the gastrointestinal tract, promote protein synthesis, and improve bowel control of bowel and symptoms of fecal incontinence or constipation in patients with spinal injury.
CONCLUSION: The current evidence shows that to some extent, electrical stimulation therapy could improve neurogenic bowel dysfunction after spinal injury. However, the number of clinical studies that have been reported on this direction was small, especially the number of randomized controlled trials. In addition, the number of subjects included in the retrieved studies was small, and the intensity, outcomes and follow-up cycles were inconsistent. More large-sample and high-quality clinical studies need to be done to evaluate the efficacy of electrical stimulation therapy in the management of bowel function in patients with spinal injury.

Abstract
BACKGROUND End-to-side nerve repair is a new tool in managing certain nerve injuries. In previous studies, it was limited to somatic nerves. Herein, we evaluate the feasibility of anorectal reinnervation after end-to-side coaptation of autonomic nerve to somatic nerve. MATERIALS AND METHODS Forty adult male Sprague-Dawley rats were randomly divided into three groups: end-to-side coaptation group (n = 16), the left L6 and S1 spinal nerves were transected, and the distal stump of L6 ventral root (L6VR) was sutured to L4VR (L4VR) through end-to-side neurorrhaphy; no coaptation group (n = 12), rats received the same operation as the end-to-side coaptation group but without coaptation; and control group (n = 12), rats received the same operation as the end-to-side coaptation group but the L6VR was preserved. At 16 wk, using double retrograde tracing and histomorphological technique and anorectal manometry, morphological and functional properties of regenerated nerve were investigated. RESULTS Retrograde tracing indicated that the new neural pathway was established and the main nerve regeneration mechanism was axon collateral sprouting. Histology showed good axonal regeneration with end-to-side neurorrhaphy. The wet weight and morphology of left tibialis anterior muscles appeared no detrimental effect on donor nerve. Anorectal manometry showed good anorectal functional recovery. CONCLUSIONS These results suggest that the somatic motor axon ingrowth into autonomic nerve could be through collateral sprouting after end-to-side coaptation of autonomic nerve to somatic nerve. Our innovative technique of end-to-side coaptation may be of great value in anorectal reinnervation without functional impairment of the donor somatic nerve.

Abstract
Exciting new features have been described concerning neurogenic bowel dysfunction, including interactions between the central nervous system, the enteric nervous system, axonal injury, neuronal loss, neurotransmission of noxious and non-noxious stimuli, and the fields of gastroenterology and neurology. Patients with spinal cord injury, myelomeningocele, multiple sclerosis and Parkinson’s disease present with serious upper and lower bowel dysfunctions characterized by constipation, incontinence, gastrointestinal motor dysfunction and altered visceral sensitivity. Spinal cord injury is associated with severe autonomic dysfunction, and bowel dysfunction is a major physical and psychological burden for these patients. An adult myelomeningocele patient commonly has multiple problems reflecting the multisystemic nature of the disease. Multiple sclerosis is a neurodegenerative disorder in which axonal injury, neuronal loss, and atrophy of the central nervous system can lead to permanent neurological damage and clinical disability. Parkinson's disease is a multisystem disorder involving dopaminergic, noradrenergic, serotoninergic and cholinergic systems, characterized by motor and non-motor symptoms. Parkinson's disease affects several neuronal structures outside the substantia nigra, among which is the enteric nervous system. Recent reports have shown that the lesions in the enteric nervous system occur in very early stages of the disease, even before the involvement of the central nervous system. This has led to the postulation that the enteric nervous system could be critical in the pathophysiology of Parkinson's disease, as it could represent the point of entry for a putative environmental factor to initiate the pathological process. This review covers the data related to the etiology, epidemiology, clinical expression, pathophysiology, genetic aspects, gastrointestinal motor dysfunction, visceral sensitivity, management, prevention and prognosis of neurogenic bowel dysfunction patients with these neurological diseases. Embryological, morphological and experimental studies on animal models and humans are also taken into account.

Abstract
An elderly patient affected by incomplete cauda equina syndrome underwent intravesical electrostimulation (IVES) to improve impaired bladder emptying. One month after IVES treatment, which consisted of 20 daily sessions, cistometrography evidenced a normalization of urinary pattern and a concomitant, but unexpected, improvement of constipation (Wexner score from 22 to 4).This report demonstrates that IVES may be considered another viable and less invasive option for controlling constipation secondary to spinal and peripheral nerve lesions.

Abstract
BACKGROUND Electrical stimulation is an established treatment for muscle weakness. However, traditional tectonic stimulation is poorly tolerated in children as a result of discomfort. Threshold electrical stimulation performed at night reportedly increases muscle strength in a variety of neuromuscular conditions and has been well tolerated in children. QUESTIONS/PURPOSES We asked whether threshold electrical stimulation treatment at night would increase strength and function in children with myelomeningocele. METHODS In a pilot study we prospectively followed 15 treated children who served as his or her own control. The patients were provided with a stimulator and instructed to use it on areas of muscular weakness during sleep, six nights per week. Followup phone calls at 2 weeks and then monthly were performed by a physical therapist to address patient concerns. Assessments of muscle strength, monofilament sensation, and physical function using the Functional Independence Measure for Children were to be performed at 3-month intervals up to 12 months and compared with the pretreatment assessment. RESULTS Only seven of the 15 subjects completed 9 months of treatment and none finished the 1-year study. The most frequent complaint was the treatment schedule was too intensive for the benefits received. We found small gains in muscle strength, gait, and bowel continence but no changes in physical function. CONCLUSIONS Although threshold electrical stimulation made small improvements in muscle strength, the currently recommended treatment schedules are not practical for patients with myelomeningocele.

Abstract
PURPOSE A variety of electrical nerve stimulation methods has been used through the years to treat lower urinary tract dysfunction. Relevant literature was reviewed to analyze techniques and available biomedical devices, technique applicability, indications and usefulness in pediatrics. MATERIALS AND METHODS An extensive search was performed on PubMed® and MEDLINE® for scientific publications on intravesical, transcutaneous, sacral spine and root, and tibial nerve stimulation in children with lower urinary tract dysfunction of nonneurogenic and neurogenic origin. Relevant articles and controlled studies in adult patients were also considered. The search covered the period 1990 to 2009 and we found approximately 400 articles, of which 29 related to pediatrics. RESULTS Due to feasibility problems with placebo studies the majority of the studies were noncontrolled, some of them clinical trials on acute urodynamic changes during electrical stimulation or experimental research in animals. Overall only a few randomized trials were found. Regarding types of electrostimulation and indications in children the recent literature emphasizes stimulation far from the anal-genital region, such as sacral transcutaneous electrical nerve stimulation, mainly for refractory overactive bladder. Intravesical stimulation is the procedure of choice to enhance sensation in patients with incomplete neurogenic lesions. Percutaneous tibial nerve stimulation is tolerated by children but has been poorly studied. Sacral neuromodulation using implanted devices remains questionable and needs further clarification of its indications. Magnetic stimulation has rarely been used in children to date. More experimental studies are needed to assess the method of action and refine the parameters of stimulation. CONCLUSIONS Clinical controlled trials vs sham devices and predictable variables for successful response are urgently needed to address an apparently renewed focus on the use of nerve stimulation in the treatment of pediatric lower urinary tract symptoms.

Abstract
Many families who have a child with spina bifida identify establishing an effective bowel program as one of the major challenges they face; yet, we know little about a family's experience with this process. The purpose of this qualitative study was to describe the parent's experience. Seven parents were interviewed by telephone. Content analysis yielded four themes: (a) long complicated journey, (b) the impact of the journey on the child, (c) the family struggle, and (d) the promise of the future. The major contribution of this study is a compelling description of one of the most difficult areas for these children and their families. A better understanding of this issue enhances the health care providers' ability to deliver optimal health care.

Abstract
OBJECTIVE To investigate the effects of intravesical electrical stimulation (IVES) on bladder function and synaptic neurotransmission in the lumbosacral spinal cord in the spinalized rat, as the clinical benefits of IVES in patients with increased residual urine or reduced bladder capacity have been reported but studies on the mechanism of IVES have mainly focused on bladder A delta afferents in central nervous system-intact rats. MATERIALS AND METHODS In all, 30 female Sprague-Dawley rats were divided equally into three groups: normal control rats, sham-stimulated spinalized rats and IVES-treated spinalized rats. IVES was started 5 weeks after spinal cord injury (SCI) and was performed 20 min a day for 5 consecutive days. At 7 days after IVES, conscious filling cystometry was performed. Sections from the L6 and S1 spinal cord segments were examined for n-methyl-d-aspartic acid receptor 1 (NMDAR1) subunit and gamma-aminobutyric acid (GABA) immunoactivity. RESULTS In IVES-treated spinalized rats, the number and maximal pressure of nonvoiding detrusor contractions were significantly less than in sham-stimulated spinalized rats. The mean maximal voiding pressure was also lower in IVES-treated than in sham-stimulated spinalized rats. IVES significantly reduced the interval between voiding contractions compared with the untreated spinalized rats. There was an overall increase in NMDAR1 immunoactivity after SCI, which was significantly lower in IVES-treated spinalized rats. Immunoactivity of GABA after SCI was significantly lower than in the control group and was significantly higher in IVES-treated spinalized rats. CONCLUSION Our results suggest that IVES might affect voiding contractions in addition to inhibiting C-fibre activity and that IVES seems to have a more complex effect on the bladder control pathway. For synaptic neurotransmission in the spinal cord, IVES could possibly shift the balance between excitation and inhibition towards inhibition.

Abstract
AIMS The anorectum and lower urinary tract (LUT) are closely related organs: anorectal and LUT dysfunction often occur concomitant, and therapeutic actions in one organ may influence function of the other. The aim of this study was to explore the physiologic relationship between anorectal and LUT function in healthy volunteers. METHODS Two groups of healthy volunteers were studied. Anorectal and LUT sensory function was evaluated in ten volunteers during rectal balloon and bladder filling. The second group of 100 volunteers reported on defecation and micturition during five toilet visits. They graded perception on rectal and bladder fullness on a visual analogue scale and marked which organ evacuation started first. RESULTS The volumes at which the different sensations of rectal filling during balloon distension were perceived was significantly higher with full bladder than with empty bladder (P<0.04). Five hundred toilet visits were described. Although mean perception grade of rectal fullness was significantly higher than for bladder fullness (P<0.0001), defecation started only in 36% of the reported visits before micturition. Only when the rectum was considered completely full, or the bladder completely empty, defecation occurred more frequently before micturition. In all other cases, micturition more frequently occurred before defecation. CONCLUSIONS When the bladder is full, sensation of rectal filling is decreased. When healthy people visit the toilet to defecate, the initiation of micturition often precedes that of defecation, even if both organs are considered equally full.
