Bladder management is the top health concern among adults with a spinal cord injury.

INTRODUCTION AND OBJECTIVE: Individuals with spinal cord injury (SCI) commonly experience secondary complications though it is not known how they prioritize these different health domains. Using the Neurogenic Bladder Research Group (NBRG) SCI registry, our objective was to identify the top health concerns of individuals with SCI and identify factors that may be associated with these choices with particular focus on urologic issues that participants face. METHODS: Participants in the NBRG registry were asked: "What are the top 3 problems that affect you on a daily basis?" Urinary symptoms and QoL were assessed with the Neurogenic Bladder Symptom Score (NBSS). Multivariate regression was used to identify factors related to selecting a top ranked health issue. RESULTS: Among our 1461 participants, 882 (60.4%) were men and the median age was 45.1 years (IQR 25.3-64.9). Bladder management was the most commonly top ranked primary issue (39%) followed by pain (16.4%) and bowel management (11.6%). Factors associated with ranking bladder management as the primary concern included years since injury (OR 1.01 [1.00-1.02], p = 0.042), higher (worse) total NBSS (OR 1.05 [1.03-1.06], p < 0.001), and higher (worse) NBSS QoL (OR 1.25 [1.12-1.41], p < 0.001). Reporting chronic pain on a daily basis was associated with ranking pain as the primary health concern (OR 41.7 [15.7-170], p < 0.001). CONCLUSIONS: In this cohort, bladder management was ranked as the top health issue and increasing time from injury was associated with increased concern over bladder management. More bladder symptoms were also associated with ranking bladder management as a primary concern while bladder management method and urinary tract infections rate were not.

Regional Heterogeneity in Intestinal Epithelial Barrier Permeability and Mesenteric Perfusion After Thoracic Spinal Cord Injury.

BACKGROUND: Spinal cord injury (SCI) disrupts intestinal barrier function, thereby increasing antigen permeation and leading to poor outcomes. Despite the intestinal tract's anatomic and physiologic heterogeneity, studies following SCI have not comprehensively addressed intestinal pathophysiology with regional specificity. AIMS AND METHODS: We used an experimental model of high thoracic SCI to investigate (1) regional mucosal oxidative stress using dihydroethidium labeling; (2) regional paracellular permeability to small- and large-molecular probes via Ussing chamber; (3) regional intestinal tight junction (TJ) protein expression; and (4) hindgut perfusion via the caudal mesenteric artery. RESULTS: Dihydroethidium staining was significantly elevated within duodenal mucosa at 3-day post-SCI. Molar flux of [14C]-urea was significantly elevated in duodenum and proximal colon at 3-day post-SCI, while molar flux of [3H]-inulin was significantly elevated only in duodenum at 3-day post-SCI. Barrier permeability was mirrored by a significant increase in the expression of pore-forming TJ protein claudin-2 in duodenum and proximal colon at 3-day post-SCI. Claudin-2 expression remained significantly elevated in proximal colon at 3-week post-SCI. Expression of the barrier-forming TJ protein occludin was significantly reduced in duodenum at 3-day post-SCI. Caudal mesenteric artery flow was unchanged by SCI at 3 days or 3 weeks despite significant reductions in mean arterial pressure. CONCLUSION: These data show that T3-SCI provokes elevated mucosal oxidative stress, altered expression of TJ proteins, and elevated intestinal barrier permeability in the proximal intestine. In contrast, mucosal oxidative stress and intestinal barrier permeability were unchanged in the hindgut after SCI. This regional heterogeneity may result from differential sensitivity to reduced mesenteric perfusion, though further studies are required to establish a causal link. Understanding regional differences in intestinal pathophysiology is essential for developing effective treatments and standards of care for individuals with SCI.

Experience of rehabilitation specialist nurses in providing bowel care for stroke patients: A qualitative study.

AIMS: This study aims to explore the experiences of rehabilitation specialist nurses in providing bowel care to stroke patients and to identify the factors that either facilitate or hinder their practice. DESIGN: This was a descriptive qualitative design study. METHODS: Between May 2022 and October 2022, we conducted in-depth and semi-structured interviews with 12 rehabilitation specialist nurses from two tertiary hospitals in Changsha, China. Thematic analysis was employed to analyse the interview transcripts. FINDINGS: Three key themes were revealed from our analysis: (1) acceptance of bowel care as a process, (2) high level of recognition improves the experience and (3) challenges stemming from limited knowledge and rights. Acceptance of bowel care as a dynamic process, coupled with a high level of recognition, enabled nurses to prioritize the health and safety of patients over personal feelings and achieve professional accomplishments. However, they encountered challenges in terms of professional development and restricted prescribing rights for bowel care. CONCLUSION: The experiences of rehabilitation specialist nurses in providing bowel care are dynamic. These findings have important implications for healthcare improvement, including the need for collaboration with healthcare professionals and nurturing nurses' self-identity, comprehensive training plans, innovative programs and expanding the scope of rehabilitation specialist nurses' rights. IMPACT: This study enhances our understanding of the challenges faced by rehabilitation specialist nurses caring for stroke patients with neurogenic bowel dysfunction. The findings provide insights into how to enhance bowel care experience and develop further in this field. REPORTING METHOD: This study adhered to the EQUATOR guideline and utilized the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTIONS: This study involved participants who were registered nurses, and there were no contributions from patients or public.

Effectiveness of acupoint stimulation combined with neurogenic bowel training on constipation in stroke patients: a retrospective study.

OBJECTIVE: To analyze the effectiveness of acupoint stimulation combined with neurogenic bowel training on constipation in stroke patients. METHODS: A retrospective analysis was conducted on the clinical data of 89 stroke patients with constipation admitted to our hospital from July 2022 to January 2024. All patients met the inclusion and exclusion criteria. The control group (n = 42) received neurogenic bowel training intervention, while the experimental group (n = 47) received finger acupoint stimulation combined with neurogenic bowel training intervention. Four outcome measures including intervention effects, bowel movements, Constipation Scoring System (CSS), and Scores on the Patient Assessment of Constipation Quality of Life (PAC-QOL) were compared between the two groups. RESULTS: The total intervention effective rate in the experimental group (91.49%) was significantly higher than that in the control group (73.81%) (p < 0.05). Two weeks after intervention, the experimental group had significantly better first bowel movement time, average bowel movement time, and bowel movement interval time compared to the control group (p < 0.05). One and 2 weeks after intervention, the CSS and PAC-QOL scores in the experimental group were significantly better than those in the control group (p < 0.05). CONCLUSION: Acupoint stimulation combined with neurogenic bowel training significantly improves constipation in stroke patients. Compared to neurogenic bowel training alone, the combined application of acupoint stimulation further improves bowel movements, reduces constipation severity, and enhances the quality of life in patients. Therefore, it is worthy of clinical promotion.

The choice for colostomy following spinal cord injury: A grounded theory study.

AIM: Explore experiences and choices related to bowel management following spinal cord injury. BACKGROUND: In one UK spinal centre, more are choosing a colostomy soon after injury in contravention of professional guidelines. Reasons for this were unknown. METHODS: Grounded theory study using semi-structured interviews with 12 individuals living with spinal cord injury. RESULTS: All 'Experienced Loss' related to bowel function. Those who chose colostomy later 'Progressed into Suffering'. Colostomy transformed lives and was likened to 'Being Alive Again'. 'Failures of Care' contributed to experiences and decision-making. CONCLUSION: Possessing information and choice emerge as key in transforming lives following spinal cord injury. They allow individuals to make choices from a lifeworld perspective, which may differ from those professionals assume. Present neurogenic bowel management guidelines fail to account for the wider lifeworlds of those they are designed for. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: An imperative emerges to make information and choice available and involve patients in the reconstruction of guidelines. IMPACT: Unique knowledge emerges about patient experiences and motivations, and points to a patient-led revolution in how bowel management following spinal cord injury is understood and managed. The imperative for adequate access to information and choice is demonstrated. REPORTING METHOD: EQUATOR Standards for Reporting Qualitative Research (SRQR) were adhered to. PATIENT OR PUBLIC CONTRIBUTION: The methodology facilitated discussion of areas important to patients and made them co-constructors of theory.

Content, face, and construct validity of the Irritable Bowel Syndrome Quality of Life (IBS-QOL) as a measure of bowel-related quality of life in spinal cord injury.

INTRODUCTION: Neurogenic bowel dysfunction is commonly encountered after a spinal cord injury (SCI), leading to a tremendous impact on quality of life (QOL). The neurogenic bowel dysfunction score (NBDS) is commonly used to measure the severity of bowel dysfunction and predict QOL. However, there is no comprehensive instrument to assess bowel-specific QOL for SCI patients. Instead, the Irritable Bowel Syndrome-Quality of Life (IBS-QOL) questionnaire evaluates the impact of bowel dysfunction on several aspects of QOL, although this questionnaire has not been validated for the SCI population. Motivated by the compelling need of instruments to accurately evaluate the QOL in patients who develope NBD after SCI, we aimed to assess the construct, content, and face validity of IBS-QOL in this population. METHODS: Adult SCI patients with at least 3 months after their injury were recruited from the outpatient clinic of a national rehabilitation hospital. Patients completed the NBDS and IBS-QOL via telephone interview or paper survey in the clinic. Content and face validity were assessed via interviews with professionals with expertise in providing chronic care for SCI, as well as a subgroup of patients. Construct validity was assessed using the hypotheses testing method. Internal consistency was assessed using Cronbach's ⍺. Factor analysis was performed to assess the dimensionality of the IBS-QOL in the SCI population. RESULTS: A total of 106 patients with a median age of 45.5 years (interquartile range: 21-79) participated in the study. The majority of the sample were men (n = 82, 77%) and had endured thoracolumbar injuries (n = 74, 71.2%). Twelve patients (seven English- and five Spanish speakers) and six professionals took part in content/face validation interviews. The median IBS-QOL total score was 15.91/100 (interquartile range: 4.55-33.14). IBS-QOL differentiated the subgroups of patients with severe bowel symptoms in terms of uneasiness, sweating, or headaches during bowel emptying (p = 0.0003), time spent on bowel emptying (p = 0.0065), flatus incontinence (p = 0.0076), and overall satisfaction with bowel function (p < 0.001), demonstrating its adequate construct validity. Interviews with the patients and professionals supported the comprehensiveness, comprehensibility, and relevance of IBS-QOL for assessment of bowel-related QOL in the SCI population. Item-level analysis of professional responses showed that 97% of questions were relevant to the construct and population of interest. Internal consistency analysis yielded a Cronbach's ⍺ of 0.9684. Exploratory factor analysis yielded six underlying factors which cumulatively accounted for 72.21% of the total variance, reflecting the dimensionality of bowel-related QOL in SCI population. DISCUSSION: IBS-QOL questionnaire is a comprehensive measure of bowel-related QOL which encompasses the concerns of SCI patients. Our findings support the content, face and construct validity of IBS-QOL as a measure of bowel-related QOL in SCI. Further studies are warranted to assess the reliability and responsiveness of IBS-QOL, and to evaluate its performance across different patient populations.

Neurophysiological Effects of Electrical Stimulation on a Patient with Neurogenic Bowel Dysfunction and Cauda Equina Syndrome after Spinal Anesthesia: A Case Report.

Neurogenic bowel dysfunction (NBD) is common in patients with cauda equina syndrome (CES). Previous studies have reported that electrical stimulation (ES) improves NBD but more neurophysiologic evidence is required. This case report describes a patient who experienced difficulty with defecation as a result of cauda equina syndrome (CES) that developed after a cesarean section performed 12 years ago under spinal anesthesia. The neurophysiological effects were assessed using the bulbocavernosus reflex (BCR) and electromyography (EMG). Two ES treatments, interferential current therapy and transcutaneous electrical stimulation, were used to stimulate the intestine and the external anal sphincter, respectively. The BCR results showed right-side delayed latency and no response on the left side. Needle EMG revealed abnormal spontaneous activities of the bilateral bulbocavernosus (BC) muscles. Electrodiagnostic testing revealed chronic bilateral sacral polyradiculopathy, compatible with CES. After treatment, the patient reported an improved perianal sensation, less strain and time for defecation than before, and satisfaction with her bowel condition. At the follow-up electrodiagnosis, the BCR latency was normal on the right side-needle EMG revealed reductions in the abnormal spontaneous activities of both BC muscles and re-innervation of the right BC muscle. Electrodiagnostic testing can offer insight into the neurophysiological effects of ES, which can help in understanding the mechanism of action and optimizing the therapy for patients with NBD.

Spinal cord injury is associated with changes in synaptic properties of the mouse major pelvic ganglion.

Spinal cord injury (SCI) has substantial impacts on autonomic function. In part, SCI results in loss of normal autonomic activity that contributes to injury-associated pathology such as neurogenic bladder, bowel, and sexual dysfunction. Yet little is known of the impacts of SCI on peripheral autonomic neurons that directly innervate these target organs. In this study, we measured changes in synaptic properties of neurons of the mouse major pelvic ganglion (MPG) associated with acute and chronic SCI. Our data show that functional and physiological properties of synapses onto MPG neurons are altered after SCI and differ between acute and chronic injury. After acute injury excitatory postsynaptic potentials (EPSPs) show increased rise and decay time constants leading to overall broader and longer EPSPs, whereas in chronic-injured animals EPSPs are reduced in amplitude and show faster rise and decay leading to shorter EPSPs. Synaptic depression and low-pass filtering are also altered in injured animals. Finally, cholinergic currents are smaller in acute-injured animals but larger in chronic-injured animals relative to control animals. These changes in synaptic properties are associated with differences in nicotinic receptor subunit expression as well. MPG CHRNA3 mRNA levels decreased after injury, whereas CHRNA4 mRNAs increased. Furthermore, changes in the correlations of α- and ß-subunit mRNAs suggest that nicotinic receptor subtype composition is altered after injury. Taken together, our data demonstrate that peripheral autonomic neurons are fundamentally altered after SCI, suggesting that longer-term therapeutic approaches could target these neurons directly to potentially help ameliorate neurogenic target organ dysfunction.NEW & NOTEWORTHY Spinal cord injury (SCI) has substantial impacts on autonomic function, yet little is known of the impacts of SCI on autonomic neurons that directly innervate effectors impacted by injury. Here we investigated changes at the cellular level associated with SCI in neurons that are "downstream" of the central injury. An understanding of these off-target impacts of SCI ultimately will be critical in the context of effective restoration of function through neuromodulation of pharmacological therapeutic approaches.

A single centre 20-year retrospective cohort study: Percutaneous endoscopic colostomy.

AIM: Percutaneous endoscopic colostomy (PEC) represents an important intervention in specific patients. Limited data currently exist. We present the largest recorded study of patients undergoing PEC. METHODS: Retrospective analysis of consultant logbooks highlighted all patients from 1997 to 2020. Two independent reviewers assessed records. Parameters measured were age, sex, indication, number of sites, complications, mortality and survival. Three subgroups were identified: recurrent sigmoid volvulus (RSV), pseudo-obstruction and neurogenic. ANOVA, chi-squared and Fischer's exact tests were utilized; Kaplan-Meier curves estimated survival and the log-rank test was applied. A p value of <0.05 was considered statistically significant. RESULTS: Ninety-six PEC insertions were done on 91 patients (five reinsertions). There were 66 men (69%) and the mean age was 73.1 years (interquartile range 23). The indications were RSV n = 72, pseudo-obstruction n = 13, neurogenic n = 11. The 30-day complication rate was overall n = 27 (28%), RSV n = 23, pseudo-obstruction n = 4. Nine patients leaked (9.9%) (eight RSV, one pseudo-obstruction), of whom five died. 90-day mortality was 14.6% (14 patients), 18.5% (13/72) for RSV, 7.7% (1/13) for pseudo-obstruction. Overall recurrence following PEC was 10.4%. The median follow-up was 25 months (interquartile range 4.6-62.2 months). At 3, 5 and 10 years survival was 46%, 34% and 26% for RSV, 70%, 55% and 15% for pseudo-obstruction and 91%, 91% and 81% for neurogenic respectively. CONCLUSION: Recurrent sigmoid volvulus and pseudo-obstruction patients undergoing PEC compared to neurogenic patients have poorer outcomes with higher complication rates and shorter life expectancy. We advocate that high volume specialist units undertake PEC. The significant associated risks of PEC require careful consideration when determining patient suitability. Utilizing risk stratification scores may help guide shared decision making between patients, relatives and clinicians.

An overview of transanal irrigation devices: an update.

Transanal irrigation (TAI) is safe and effective treatment for constipation and faecal incontinence, but it should not be carried out before less invasive options have been tried. A thorough patient assessment and consideration of their preferences and tolerance should determine suitability and system choice. The range of available TAI equipment can be overwhelming. Therefore, to aid health professionals, this article presents a summary of the latest available devices on the market, as well as guidance on how to select a suitable device. TAI devices can be categorised into low-or high-volume; cones, catheters or balloon inflating devices; manual, electric pump or gravity-fed systems; and bed systems. Determining whether a low or high volume of water is required is a good starting point for device selection. Nurses should be aware of available devices and select one most suitable for a patient, as well as adequately train them in its usage and provide follow-up support. Nurses should communicate the potential improvement to quality of life TAI can offer and encourage adherence to avoid premature discontinuation.

Effectiveness of percutaneous posterior tibial nerve stimulation for the management of bowel dysfunction in multiple sclerosis patients.

BACKGROUND: Neurogenic bowel dysfunctions (NBDs) in the form of both fecal incontinence (FI) and functional constipation (FC) are frequent in multiple sclerosis (MS) patients and significantly affect their quality of life. Therapeutic options are limited. OBJECTIVE: To investigate effectiveness of percutaneous posterior tibial nerve stimulation (PTNS) in MS patients suffering from FI and FC. METHODS: Prevalence and severity of FI and FC were prospectively collected among MS patients undergoing 12 weeks of PTNS for neurogenic bladder. The Cleveland Clinic Fecal Incontinence Score (CCFIS) and the Rome III criteria were used to define FI and FC, respectively. Subjective treatment satisfaction was estimated using the Benefit Satisfaction and Willingness to Continue (BSWC) questionnaire. RESULTS: A total of 60 patients undergoing PTNS suffered from NBDs (25 FI+/FC+, 5 FI+/FC-, 30 FI-/FC+). Median CCFIS decreased after PTNS from 12.0 (11.0-13.0) to 8.5 (7.0-11.0, p < 0.001), with particular improvements in liquid and flatal incontinence, pads' need, and lifestyle restrictions. Seven patients became FC free after PTNS and no patients developed FC during the study (p = 0.023). More than 50% of the patients were satisfied and willing to continue PTNS at study end. CONCLUSION: PTNS represents a valid minimally invasive alternative treatment for MS patients suffering from NBDs.

Botulinum toxin type-A infiltration of the external anal sphincter to treat outlet constipation in motor incomplete spinal cord injury: pilot cohort study.

BACKGROUND: Outlet constipation is a major problem in spinal cord injury (SCI) patients. We aimed to study the efficacy of external anal sphincter (EAS) infiltration with type-A botulinum toxin (BTX-A) in motor incomplete SCI patients with outlet constipation. METHODS: Double blind, randomized, placebo controlled, comparative study in 16 motor incomplete SCI subjects. Patients were randomly assigned toreceive100 UI of BTX-A (n = 9) or physiologic serum infiltration (n = 7) in the EAS under electromyographic guidance. Outcome measures included a questionnaire for clinical bowel function evaluation, colonic transit time and anorectal manometry. All assessments were done at baseline, 1 and 3 months after treatment. RESULTS: Fourteen patients completed the study. In the BTX-A group we observed an improvement of subjective perception of bowel function (p = 0.01), constipation (p = 0.02) and neurogenic bowel dysfunction score (p = 0.02). The anorectal manometry revealed are duction of EAS voluntary contraction pressure (p = 0.01). No changes were observed in the placebo group. No significant side effects were observed in none of the groups. CONCLUSION: BTX-A infiltration of the EAS is a safe technique that in motor incomplete SCI, decreases the EAS contraction and the anal canal pressure during straining, and improves outlet constipation symptoms. Future studies in larger populations are needed.

Current State of Knowledge on Digital Rectal Stimulation in Individuals With Traumatic and Nontraumatic Spinal Cord Injury: A Scoping Review.

OBJECTIVES: To map and characterize the nature of the evidence on the use of digital rectal stimulation for bowel management in individuals with spinal cord injury (SCI). DATA SOURCES: Five electronic databases were searched (ie, MEDLINE, EMBASE, CINAHL, Cochrane CENTRAL, and Cochrane Incontinence Group) from 1990 to November 2019. STUDY SELECTION: Articles that provided information on the use of digital rectal stimulation either alone or in combination with treatments were included. Title and abstract screening was split between 2 reviewers after reaching consensus on the first 100 studies screened. Full-texts were reviewed independently by 2 reviewers. Discrepancies were resolved by a third reviewer. DATA EXTRACTION: The data extraction form was developed by 2 reviewers and piloted. Data were extracted by one reviewer and checked for accuracy by a second reviewer. DATA SYNTHESIS: A total of 4841 studies were screened, including 425 full text articles; 33 articles were identified. Thirty-two studies focused solely on individuals with SCI and 1 study explored the experiences of caregivers of individuals with SCI. The majority of participants were aged between 30 and 59 years old. Most studies used quantitative methods (n=30, 91%). Fourteen of the studies (42%) were cross-sectional. Within experimental or quasiexperimental designs, digital rectal stimulation was commonly studied as an adjunct to other methods such as suppositories or enemas. Incontinence and defecation time were the most commonly examined outcomes. CONCLUSION: There were few studies found that focus on digital rectal stimulation. Further studies examining experience, effectiveness, complications, and long-term outcomes are warranted.

Effect of Different Forms of Activity-Based Recovery Training on Bladder, Bowel, and Sexual Function After Spinal Cord Injury.

OBJECTIVES: To investigate whether the urogenital and bowel functional gains previously demonstrated post-locomotor step training after chronic spinal cord injury could have been derived due to weight-bearing alone or from exercise in general. DESIGN: Prospective cohort study; pilot trial with small sample size. SETTING: Urogenital and bowel scientific core facility at a rehabilitation institute and spinal cord injury research center in the United States. PARTICIPANTS: Men and women (N=22) with spinal cord injury (American Spinal Injury Association Impairment Scale grades of A-D) participated in this study. INTERVENTIONS: Approximately 80 daily 1-hour sessions of either stand training or nonweight-bearing arm crank ergometry. Comparisons were made with previously published locomotor training data (step; N=7). MAIN OUTCOME MEASURES: Assessments at both pre- and post-training timepoints included cystometry for bladder function and International Data Set Questionnaires for bowel and sexual functions. RESULTS: Cystometry measurements revealed a significant decrease in bladder pressure and limited improvement in compliance with nonweight-bearing exercise but not with standing. Although International Data Set questionnaires revealed profound bowel dysfunction and marked deficits in sexual function pretraining, no differences were identified poststand or after nonweight-bearing exercise. CONCLUSIONS: These pilot trial results suggest that, although stand and weight-bearing alone do not benefit pelvic organ functions after spinal cord injury, exercise in general may contribute at least partially to the lowering of bladder pressure and the increase in compliance that was seen previously with locomotor training, potentially through metabolic, humoral, and/or cardiovascular mechanisms. Thus, to maximize activity-based recovery training benefits for functions related to storage and emptying, an appropriate level of sensory input to the spinal cord neural circuitries controlling bladder and bowel requires task-specific stepping.

Problems people with spinal cord injury experience accessing help with bowel care when hospitalised outside a specialist spinal injury service.

AIMS AND OBJECTIVES: To examine the nature of problems experienced by people with spinal cord injury (SCI) when accessing help to maintain recommended bowel regimes while hospitalised outside a specialist spinal injury service. BACKGROUND: Bowel dysfunction is one particularly undesirable aspect of life with a SCI, with constipation and incontinence common. DESIGN: Descriptive qualitative. METHODS: Accounts of problems encountered in hospitals in New South Wales Australia collected during interviews with 11 people living with SCI and 12 responses provided by spinal clinicians via an online survey were subjected to thematic analysis. The COREQ guidelines were followed for reporting. RESULTS: There were similarities across data collected from both sources. Individuals with SCI described instances where their bowel care needs did not fit with the pace and processes in acute hospitals. The clinician data pointed to a failure of healthcare professionals to assist people with SCI to maintain bowel care regimes recommended by specialist spinal services. Both groups described times when bowel care received was unreliable and fragmented, along with reports of staff who were unwilling and/or unable to provide the assistance required. Many and varied physical and psychosocial repercussions for individuals were associated with these system failures. In some instances, rather than restoring health, being admitted to hospital represented a significant health risk. CONCLUSION: A failure of hospital systems to meet the bowel care needs of people with SCI when hospitalised outside a specialist spinal unit was identified. System and individual factors contributed to these problems, hence addressing them requires both system and individual responses. RELEVANCE TO CLINICAL PRACTICE: If this problem is left unaddressed, the health and quality of life of people with SCI will continue to be compromised. Nursing scope of practice needs to be clarified and communicated to nurses outside specialist spinal injury units in relation to their role in maintaining bowel care regimes recommended for their patients by spinal specialists, and nurses need to ensure they possess the skills required. To allocate the time needed to provide this care, individual nurses need the support of the whole nursing team, including managers who are prepared to arrange additional staff when needed.

Excretory dysfunction and quality of life after a spinal cord injury: A cross-sectional study.

AIMS AND OBJECTIVES: To determine the aspects of excretory dysfunction most influential in determining the quality of life of survivors of spinal cord injury. BACKGROUND: Excretory dysfunction is one of the most common and troublesome sequelae of spinal cord injury. Previous studies have shown that it can restrict social participation restriction, cause readmission and generally influence quality of life substantially. DESIGN: A cross-sectional survey of hospital inpatients following STOBE guidelines. METHODS: A convenience sample of 101 patients with traumatic or non-traumatic spinal cord injury were asked about their experiences of excretory dysfunction, and management and their self-perceived quality of life. Univariate analysis and multiple linear regression were performed to isolate the most important relationships. RESULTS: Only 2 of the 101 subjects professed to be unaffected by excretion dysfunction. Bladder-related dysfunction was the most frequently mentioned type of problem. Quality of life impairment was found to be most often associated with bladder accidents, bowel accidents and having more than one bladder complications. CONCLUSIONS: Excretory dysfunction substantially impacts quality of life after a spinal cord injury. Bladder accidents, bowel accidents and more than one bladder complication are factors independently influencing the quality of life of spinal cord injury survivors. RELEVANCE TO CLINICAL PRACTICE: To improve excretion-related QOL, patients' bladder and bowel self-management training should be strengthened seeking to prevent complications and reduce the risk of bladder and bowel accidents.

Sacral Neuromodulation in Patients With Neurogenic Lower Urinary Tract Dysfunction: A Multicenter Retrospective Study From China.

OBJECTIVES: This retrospective study aimed to determine the effectiveness of sacral neuromodulation (SNM) on neurogenic lower urinary tract dysfunction (NLUTD) and analyze the predictive factors. MATERIALS AND METHODS: From January 2012 to January 2020, 152 subjects with NLUTD from four medical centers in China received SNM test stimulation. Subjects were assessed via bladder diaries, postvoid residual volumes (PRVs) and neurogenic bowel dysfunction (NBD) scores before and during the testing period. Patients who showed a minimum 50% improvement in symptoms through the SNM test phase were eligible for permanent SNM implantation. RESULTS: The pooled success rate for chronic urinary retention was 31.0% (40/129), which was significantly lower (p < 0.05) than the rates for frequency-urgency (64.8%, 59/91), urinary incontinence (65.2%, 30/46), and NBD score (61.7%, 82/133). The results of the risk factor analysis showed that the urinary storage symptom was a statistically significant positive predictor (p = 0.001). CONCLUSIONS: In conclusion, SNM is an effective and reliable method for treating NLUTD, especially in patients with urinary storage symptoms. Although not all of the symptoms in every patient can be resolve, SNM still might be a superior choice together with other treatment procedures.

Small intestinal bacterial overgrowth in spinal cord injury patients. / Sobrecrecimiento bacteriano del intestino delgado en pacientes con lesión medular.

AIM: Spinal cord injury (SCI) patients may have intestinal dysmotility and digestive symptoms that are associated with small intestinal bacterial overgrowth (SIBO). The aim of this study is to describe the prevalence of SIBO in SCI patients and the risk factors of its development. METHODS: Twenty-nine consecutive SCI patients were studied (10 women/19 men; mean age 47 years), 16 with subacute injuries (<9 months) and 13 with chronic injuries (>1 year). Nine patients were affected by tetraplegia and 15 by paraplegia. Each patient underwent a glucose breath test according to the North American Consensus and the presence of abdominal symptoms was evaluated during the test. The results were compared with 15 non-neurological patients with SIBO. RESULTS: Six patients tested positive for SIBO (21%), all of them affected by SCI in the subacute phase, 6/16 vs. 0/13 in the chronic phase (P<.05) and the majority with tetraplegia, 5/9 vs. 1/19 with paraplegia (P<.05). No statistically significant relationship was found with other clinical characteristics. All the tests were positive for methane or mixed (methane and hydrogen), while only 67% of the controls had methane-predominant production (P>.05). CONCLUSION: SCI patients can develop SIBO, more frequently in the subacute phase and in tetraplegic patients, highlighting a high production of methane. This complication should be considered in neurogenic bowel management.

Effect of sacral neuromodulation on bowel dysfunction in patients with neurogenic bladder.

AIM: The aim of this retrospective study was to evaluate the clinical effect of sacral neuromodulation (SNM) on bowel dysfunction in patients with neurogenic bladder using the neurogenic bowel dysfunction (NBD) score. METHOD: Between July 2012 and July 2019, 41 patients with both neurogenic bladder and bowel dysfunction underwent permanent SNM implantation. The NBD score was used to evaluate the bowel symptoms before the testing phase and at follow-up. The first follow-up was at the time of discharge after permanent implantation. The second follow-up was conducted by telephone after discharge. RESULTS: The mean NBD score before the testing phase was 11.0 ± 5.83, whilst it significantly decreased to 5.2 ± 5.32 (n = 41, P < 0.05) at the first follow-up (32 ± 3.9 days). Before the testing phase, there were 9 patients with very minor NBD, 10 with minor NBD, 13 with moderate NBD and 9 with severe NBD. At the first follow-up, there were 26 patients with very minor NBD, 7 with minor NBD, 4 with moderate NBD and 4 with severe NBD (P < 0.05). Twenty-six patients were interviewed in the long-term follow-up (34 ± 30.9 months). The NBD score in these 26 patients was 5.6 ± 5.18, which was not significantly different from the NBD score (5.5 ± 5.33) at the first follow-up (n = 26, P > 0.05). CONCLUSION: SNM facilitates a significant reduction in NBD score in patients with neurogenic bladder and bowel dysfunction. The improvement in NBD symptoms can also be used as a future indicator to determine the clinical efficacy of permanent SNM implantation in the treatment of neurogenic bladder.

Electrical Colon Stimulation Reflexively Increases Colonic Activity.

OBJECTIVES: Most individuals with spinal cord injury have neurogenic bowel dysfunction, which includes slowed colonic motility and has a significant impact on their health and quality of life. Bowel management typically includes mechanical rectal distension to evoke a recto-colic reflex and promote bowel emptying. Electrical stimulation could replace this mechanical distension. The purpose of this study was to determine the feasibility of evoking colonic activity using electrical stimulation. MATERIALS AND METHODS: Acute experiments were conducted in eight neural-intact cats under chloralose anesthesia. Patterned electrical stimulation was administered via electrodes placed on the surface of the distal colon or proximal colon. Distal and proximal colon pressures were measured using saline-filled balloon catheters. Outcome measures included peak colonic pressure; time to onset of response; and time to peak pressure compared to baseline without stimulation. RESULTS: Stimulation elicited colonic activity in all animals. Peak colon pressures were 15 ± 28 cmH2 O and were proportional to stimulation amplitudes. Time to onset and time to peak pressure were 13 ± 19 s and 37 ± 49 s, respectively, and were not significantly affected by stimulus parameters. Proximal colon stimulation only resulted in pressure responses from the proximal colon, but distal colon stimulation resulted in both proximal and distal responses in 40% of trials. Adding isoflurane anesthesia removed this proximal response to distal stimulation. CONCLUSIONS: Distal colon stimulation evoked colonic activity. The dependence of this response on stimulation location and anesthesia suggests that responses were reflex mediated. Colonic stimulation may have the potential to improve colonic motility for individuals with neurogenic bowel dysfunction.
