Rehabilitation care of patients with neurogenic bladder after spinal cord injury:A literature review

This article reviews the research progress of rehabilitation treatment and nursing care of patients with neurogenic bladder after spinal cord injury,in order to provide reference for the rehabilitation treatment and nursing care of patients.We reviewed recent medical literature on patients with neurogenic bladder,focusing on neurogenic bladder caused by spinal cord injury.We analyzed 30 recent of publications in patients with neurogenic bladder after spinal cord injury,in addition to reviewing and evaluating the commonly used rehabilitation nursing methods for neurogenic bladder.Psychological counseling is a vital aspect which cannot be neglected in the process of neurogenic bladder rehabilitation.Hitherto,the commonly used drug and surgical treatments may have negatively impacted the mental health of patients in varying degrees.However,in clinical practice,applying intermittent catheterization in patients who have neurogenic bladder with spinal cord injury may help improve patients’life quality,mitigate psychological burden,and reduce negative emotions.

Research Progress of Acupuncture Treatment of Neurogenic Bladder after Spinal Cord Injury

Neurogenic bladder (NB) mainly occurs in patients with spinal cord injury (SCI). The pathological basis of NB is the occurrence of lesions in the urination control center, which requires systematic treatment. Western medicine has many treatment methods for this disease, which can alleviate the symptoms of the disease. However, the radical effect is not ideal and there are many adverse reactions. In comparison, acupuncture can improve the residual urine volume of NB patients and regulate the related indexes of urodynamics. There are many kinds of acupuncture therapies, such as simple acupuncture and moxibustion, which can comprehensively improve the therapeutic effect and obtain a better disease prognosis. Therefore, this article elaborates on the pathogenesis of SCI complicated with NB, the treatment mechanism, and treatment methods of acupuncture and moxibustion to provide a reference for clinical treatment.

Chondroitinase ABC combined with Schwann cell transplantation enhances restoration of neural connection and functional recovery following acute and chronic spinal cord injury

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal cord.Here we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord injury.We report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal directions.Such Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder functions.Importantly,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord injury.These findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

Outcomes of bowel program in spinal cord injury patients with neurogenic bowel dysfunction

In this study, we aimed to determine gastrointestinal problems associated with neurogenic bowel dysfunction in spinal cord injury patients and to assess the efficacy of bowel program on gastrointestinal problems and the severity of neurogenic bowel dysfunction. Fifty-five spinal cord injury patients were included in this study. A bowel program according to the characteristics of neurogenic bowel dysfunction was performed for each patient. Before and after bowel program, gastrointestinal problems（constipation, difficult intestinal evacuation, incontinence, abdominal pain, abdominal distension, loss of appetite, hemorrhoids, rectal bleeding and gastrointestinal induced autonomic dysreflexia） and bowel evacuation methods（digital stimulation, oral medication, suppositories, abdominal massage, Valsalva maneuver and manual evacuation） were determined. Neurogenic bowel dysfunction score was used to assess the severity of neurogenic bowel dysfunction. At least one gastrointestinal problem was identified in 44（80%） of the 55 patients before bowel program. Constipation（56%, 31/55） and incontinence（42%, 23/55） were the most common gastrointestinal problems. Digital rectal stimulation was the most common method for bowel evacuation, both before（76%, 42/55） and after（73%, 40/55） bowel program. Oral medication, enema and manual evacuation application rates were significantly decreased and constipation, difficult intestinal evacuation, abdominal distention, and abdominal pain rates were significantly reduced after bowel program. In addition, mean neurogenic bowel dysfunction score was decreased after bowel program. An effective bowel program decreases the severity of neurogenic bowel dysfunction and reduces associated gastrointestinal problems in patients with spinal cord injury.

Therapeutic Outcome of Botulinum Toxin Type A for Patients with Low Bladder Compliance Secondary to Spinal Cord Injury

Objective: To evaluate the efficacy and safety of botulinum toxin type A (BTX-A) in treating patients with low bladder compliance (BC) secondary to spinal cord injury (SCI). Methods: From 2011 to 2016, we retrospected patients who received BTX-A injections for LBC secondary to SCI. The primary outcomes were urodynamic parameters including maximum detrusor pressure (Pdetmax), bladder compliance (BC). Related adverse events were recorded. Results: 72 SCI patients were selected (62 males, 10 females, age range 18 - 52 years;mean age 28.5 years). 12 weeks after BTX-A injection, Pdetmax decreased from 51.02 cmH2O to 28.31 cmH2O. BC increased from 3.64 ml/cmH2O to 10.08 ml/cmH2O. 12 patients had mild transient haematuria for 1 - 2 days. Conclusion: Intradetrusor BTX-A injection was effective and safe for patients with low BC secondary to SCI.

Can Bladder Irrigation Reduce the Morbidity of Bladder Stone in Patients with Spinal Cord Injury?

Objective: To assess the safety and efficacy of bladder irrigation for reducing the morbidity of bladder stones in patients with neurological lower urinary tract dysfunction (NLUTD). Methods: From June 2012 to July 2013, patients with NLUTD were prospectively randomized and assigned to either a bladder irrigation group or a no bladder irrigation group. Bladder irrigations were performed twice a week by urologists. Patients were followed up at 6 months respectively. Primary outcomes were Incontinence-Specific Quality-of-Life Instrument (I-QoL), the rate incidences of bladder stone. All adverse events were also noted. Results: A total of 80 eligible patients participated and 78 (97.5%) patients (bladder irrigation, n = 39;no bladder irrigation, n = 39) completed 24 weeks of follow-up. Out of the 78 patients, 19 (24.3%) developed bladder stones. All occurred in no bladder irrigation group. In 8 of the 19 patients (42.1%), stones were only detected by cystoscopy. The bladder stones were mostly thin with an eggshell appearance (78.95% for diameter of stone < 5 mm, 84.21% for volume of bladder stone < 0.2 cm3). Bladder stones were removed by vigorous bladder irrigation guided by ultrasound (73.68%) or endoscopic lithotripsy (26.32%). The I-QOL was significantly better in the bladder irrigation group than in no bladder irrigation group at weeks 6, 12, 18, and 24 of follow-up. Conclusion: Bladder irrigation may be more effective and safer than no bladder irrigation for reducing the morbidity of bladder stone in spinal cord injury patients.

Long-term anodal block stimulation at sacral anterior roots promoted recovery of neurogenic bladder function in a rabbit model of complete spinal cord injury

A complete spinal cord injury model was established in experimental rabbits using the spinal cord clip compression method. Urodynamic examination was performed 2 weeks later to determine neurogenic bladder status. The rabbits were treated with anodal block stimulation at sacral anterior roots for 4 weeks. Electrical stimulation of sacral anterior roots improved urodynamic parameters of neurogenic bladder in rabbit models of complete spinal cord injury, effectively promoted urinary function, and relieved urinary retention. Immunohistochemistry results showed that a balance was achieved among expression of muscarinic receptor subunits M2, M3, ATP-gated ion channel P2X3 receptors, and 132-adrenergic receptor, and nerve growth factor expression decreased. These results suggested that long-term sacral anterior root stimulation of anodal block could＇be used to treat neurogenic bladder in a rabbit model of complete spinal cord injury.

Survey of spinal cord injury-induced neurogenic bladder studies using the Web of Science

OBJECTIVE：To identify global trends in research on spinal cord injury-induced neurogenic bladder, through a bibliometric analysis using the Web of Science. DATA RETRIEVAL：We performed a bibliometric analysis of studies on spinal cord injury-induced neurogenic bladder using the Web of Science.Data retrieval was performed using key words＂spinal cord injury＂,＂spinal injury＂,＂neurogenic bladder＂,＂neuropathic bladder＂,＂neurogenic lower urinary tract dysfunction＂,＂neurogenic voiding dysfunction＂,＂neurogenic urination disorder＂and ＂neurogenic vesicourethral dysfunction＂. SELECTION CRITERIA：Inclusion criteria：（a）published peer-reviewed articles on spinal cord injury-induced neurogenic bladder indexed in the Web of Science;（b）type of articles：original research articles and reviews;（c）year of publication：no limitation.Exclusion criteria：（a）articles that required manual searching or telephone access;（b）Corrected papers and book chapters. MAIN OUTCOME MEASURES：（1）Annual publication output;（2）distribution according to journals; （3）distribution according to subject areas;（4）distribution according to country;（5）distribution according to institution;and（6）top cited publications. RESULTS：There were 646 research articles addressing spinal cord injury-induced neurogenic bladder in the Web of Science.Research on spinal cord injury-induced neurogenic bladder was found in the Science Citation Index-Expanded as of 1946.The United States,Ireland and Switzerland were the three major countries contributing to studies in spinal cord injury-induced neurogenic bladder in the 1970s.However,in the 1990s,the United States,the United Kingdom,the Netherlands,Germany and Japan published more papers on spinal cord injury-induced neurogenic bladder than Switzerland,and Ireland fell off the top ten countries list.In this century,the United States ranks first in spinal cord injury-induced neurogenic bladder studies,followed by France,the United Kingdom,Germany,Switzerland and Japan.Subject categories including urology, nephrology and clinical neurology,as well as rehabilitation,are represented in spinal cord injury-induced neurogenic bladder studies. CONCLUSION：From our analysis of the literature and research trends,we conclude that spinal cord injury-induced neurogenic bladder is a hot topic that will continue to generate considerable research interest in the future.

The Assessment of Bladder and Urethral Function in Spinal Cord Injury Patients

The correlation between the anatomic site of spinal cord injury and real-time conditions of bladder and urethral function was assessed in order to provide a reasonable basis for the clinical treatment of neurogenic bladder. A total of 134 patients with spinal cord injuries （105 males, 29 females; averaged 34.1 years old） were involved in this retrospective analysis, including urodynamic evaluation, clinical examination and imaging for anatomical position, and Bors-Comarr classification. The associa- tions between the levels of injury and urodynamic findings were analyzed. The results showed that mean follow-up duration was 16.7 months （range 8-27 months）. Complete spinal cord injuries occurred in 21 cases, and incomplete spinal cord injuries in 113 cases. Of the 43 patients with upper motor neuron （UMN） injuries, hyperref/exia and （or） detrusor sphincter dyssynergia were demonstrated in 30 （69.8%）, 31 （72.1%） suffered low bladder compliance （less than 12.5 mL/cmH20）, 28 （65.1%） had high detrusor leak point pressures （greater than 40 cmH20）, and 34 （79.1%） had residual urine. Of the 91 patients with lower motor neuron （LMN） injuries, areflexia occurred in 78 （85.7%）, high compliance in 75 （82.4%）, low leak point pressures in 80 （87.9%）, and residual urine in 87 （95.6%）, respectively. The associations between the anatomical site of spinal cord injury and urodynamic findings were ill defined. In patients with spinal cord injury, this study revealed a significant association between the level of injury and the type of voiding dysfunction. The anatomical site of spinal cord injury can not be predicted in real-time condition of bladder and urethral function. Management of neurogenic bladder in patients with spinal cord injury must be based on urodynamic findings rather than inferences from the neurologic evaluation.

Absence of high amplitude propagating contractions in subjects with chronic spinal cord injury

AIM: To investigate the presence or absence of high amplitude propagating contractions (HAPC), as well as the other measures of colonic motility, in persons with spinal cord injury (SCI). METHODS: Prolonged colonic ambulatory manometric studies were performed on 14 male volunteers: 8 with SCI (mean age, 59 ± 13 years; mean duration of injury, 13 ± 4 years) and 6 healthy able-bodied controls (mean age, 57 ± 10 years). A solid-state manometry catheter was endoscopically clipped to the splenic flexure. Recording was performed for > 24 h after manometric catheter placement. RESULTS: HAPC were absent in individuals with SCI during pre-sleep, sleep, and post-sleep phases. HAPC were significantly increased after awakening in non-SCI controls (0.8 ± 0.2 HAPC/h vs 10.5 ± 2.0 HAPC/h, P < 0.005). The motility index was lower in those with SCI than in controls preand post-sleep (SCI vs non-SCI: Pre-sleep, 2.4 ± 0.4 vs 8.8 ± 1.9, P < 0.01; Post-sleep, 4.3 ± 0.8 vs 16.5 ± 4.5, P < 0.05). However, a sleepinduced depression of colonic motility was observed in both the SCI and non-SCI groups (Pre-sleep vs Sleep, non-SCI: 8.8 ± 1.9 vs 2.1 ± 0.9, P < 0.002; SCI: 2.4 ± 0.4 vs 0.2 ± 0.03, P < 0.001), with the motility index of those with SCI during sleep not significantly different than that of the controls. CONCLUSION: HAPC were not observed in individuals with SCI preor post-sleep. A sleep-induced depression in general colonic motility was evident in SCI and control subjects.

Urinary bladder cancer as a late sequela of traumatic spinal cord injury

Background:Traumatic spinal cord injury(SCI)is also a combat-related injury that is increasing in modern warfare.The aim of this work is to inform medical experts regarding the different course of bladder cancer in able-bodied patients compared with SCI patients based on the latest medical scientific knowledge,and to present decision-making aids for the assessment of bladder cancer as a late sequela of traumatic SCI.Methods:A study conducted between January 1998 and December 2019 in the BG Trauma Hospital Hamburg formed the basis for the decision-making aids.Urinary bladder cancer was diagnosed in 40 out of 7396 treated outpatient and inpatient SCI patients.General patient information,latency period,age at initial diagnosis,type of bladder management and survival of SCI patients with bladder cancer were collected and analysed.T category,grading and tumor entity in these patients were compared with those in the general population.Relevant bladder cancer risk factors in SCI patients were analysed.Furthermore,relevant published literature was taken into consideration.Results:Initial diagnosis of urinary bladder cancer in SCI patients occurs at a mean age of 56.4 years(SD±10.7 years),i.e.,approximately 20 years earlier as compared with the general population.These bladder cancers are significantly more frequently muscle invasive(i.e.,T category≥T2)and present a higher grade at initial diagnosis.Furthermore,SCI patients show a significantly higher proportion of the more aggressive squamous cell carcinoma than that of the general population in areas not endemic for the tropical disease schistosomiasis.Consequently,the survival time is extremely unfavourable.A very important finding,for practical reasons is that,in the Hamburg study as well as in the literature,urinary bladder cancer is more frequently observed after 10 years or more of SCI.Based on these findings,a matrix was compiled where the various influencing factors,either for or against the recognition of an association between SCI and urinary bladder cancer,were weighted according to their relevance.Conclusions:The results showed that urinary bladder cancer in SCI patients differs considerably from that in ablebodied patients.The presented algorithm is an important aid in everyday clinical practice for assessing the correlation between SCI and bladder cancer.

Disruption of sensation-dependent bladder emptying due to bladder overdistension in a complete spinal cord injury:A case report

BACKGROUNDAutonomic dysreflexia (AD) can be a life-threatening condition in patients withspinal cord injury. It is important to prevent bladder overdistension in thesepatients as it may trigger AD. Sensation-dependent bladder emptying (SDBE), asa method of bladder management, improves the quality of life and allowsphysiologic voiding. In this study, we report disruption of the SDBE habit afterbladder overdistension leading to AD with chest pain.CASE SUMMARYA 47-year-old male with a diagnosis of C4 American Spinal Cord InjuryAssociation impairment scale A had been emptying his bladder using the cleanintermittent catheterization method with an itchy sensation in the nose as asensory indication for a full bladder for 23 years, and the usual urine volume wasabout 300-400 mL. At the time of this study, the patient had delayed catheterizationfor approximately five hours. He developed severe abdominal pain andheadache and had to visit the emergency room for bladder overdistension (800mL) and a high systolic blood pressure (205 mmHg). After control of AD, ahypersensitive bladder was observed despite using anticholinergic agents. Thesensation indicating bladder fullness changed from nose itching to pain in theabdomen and precordial area. Moreover, the volume of the painful bladder fillingsensation became highly variable and was noted when the bladder urine volumeexceeded only 100 mL. The patient refused intermittent clean catheterization Finally, a cystostomy was performed, which relieved the symptoms.CONCLUSIONPatients using physiologic feedback, such as SDBE, for bladder management arerecommended to avoid bladder overdistension.

Tamsulosin-induced life-threatening hypotension in a patient with spinal cord injury:A case report

BACKGROUND Tamsulosin,a selectiveα1-adrenergic receptor antagonist,is commonly used for treating neurogenic bladder in patients with spinal cord injury(SCI).No severe adverse events have been described with such tamsulosin use.To our knowledge,we report the first case of severe life-threatening hypotension as an adverse effect of tamsulosin in a person with SCI.Therefore,we report this case to inform that this severe adverse effect of tamsulosin can occur when treating patients with SCI.CASE SUMMARY A 59-year-old woman was diagnosed with cervical spinal cord myelopathy and was classified as American Spinal Injury Association Impairment Scale D,neurological level of injury C3.Because she suffered from voiding difficulty due to neurogenic bladder,we prescribed tamsulosin.Her vital signs remained stable,but occasional hypotensive symptoms followed defecation.We reduced the dose of tamsulosin,but after administering tamsulosin for 9 d,she experienced lifethreatening hypotension with no evidence of hypovolemic shock,neurogenic shock,cardiogenic shock,or septic shock.A hypotensive condition induced by tamsulosin was the suspected cause,and her symptoms could be associated with adverse effects of tamsulosin.As symptoms resolved after stopping tamsulosin,and no other reason was found,we concluded that tamsulosin was the cause of her symptoms.CONCLUSION Caution for severe hypotension is needed when administering tamsulosin for neurogenic bladder in a patient with SCI.

Fluoxetine,a selective serotonin reuptake inhibitor used clinically,improves bladder function in a mouse model of moderate spinal cord injury

After spinal cord injury,the upward conduction of the spinal cord is lost,resulting in the loss of micturition control,which manifests as detrusor sphincter dyssynergia and insufficient micturition.Studies have shown that serotonergic axons play important roles in the control of the descending urination tract.In this study,mouse models of moderate spinal cord contusions were established.The serotonin agonists quipazine(0.2 mg/kg),8-hydroxy-2-(di-n-propylamino)tetralin(8-OH-DAPT,0.1 mg/kg),buspirone(1 mg/kg),sumatriptan(1 mg/kg),and rizatriptan(50 mg/kg),the serotonin reuptake inhibitors fluoxetine(20 mg/kg)and duloxetine(1 mg/kg),and the dopamine receptor agonist SKF-82197(0.1 mg/kg)were intraperitoneally administered to the model mice 35 days post-injury in an acute manner.The voided stain on paper method and urodynamics revealed that fluoxetine reduced the amount of residual urine in the bladder and decreased bladder and external urethral sphincter pressure in a mouse model of moderate spinal cord injury.However,fluoxetine did not improve the micturition function in a mouse model of severe spinal cord injury.In contrast,the other serotonergic drugs had no effects on the micturition functions of spinal cord injury model mice.This study was ethically approved by the Institutional Animal Care and Use Committee of Jiangsu Province Hospital of Chinese Medicine(approval No.2020DW-20-02)on September 11,2020.

Objective To analyze the clinical features of the multiple trauma patients combined with spine and spinal cord injuries.Methods A retrospective study was performed in143multiple trauma patients combined with spine and spinal

Tanshinone ⅡA improves functional recovery in spinal cord injury-induced lower urinary tract dysfunction

Tanshinone ⅡA, extracted from Salvia miltiorrhiza Bunge, exerts neuroprotective effects through its anti-inflammatory, anti-oxidative and anti-apoptotic properties. This study intravenously injected tanshinone ⅡA 20 mg/kg into rat models of spinal cord injury for 7 consecutive days. Results showed that tanshinone ⅡA could reduce the inflammation, edema as well as compensatory thickening of the bladder tissue, improve urodynamic parameters, attenuate secondary injury, and promote spinal cord regeneration. The number of hypertrophic and apoptotic dorsal root ganglion（L6–S1） cells was less after treatment with tanshinone ⅡA. The effects of tanshinone ⅡA were similar to intravenous injection of 30 mg/kg methylprednisolone. These findings suggested that tanshinone ⅡA improved functional recovery after spinal cord injury-induced lower urinary tract dysfunction by remodeling the spinal pathway involved in lower urinary tract control.

Role of melatonin in spinal cord injury

Spinal cord injury (SCI) impairs the au-tonomic nervous system and is associated with dysfunc-tion or failure of multiple organs. Rehabilitation after SCI is a complicated process that involves improvement of motor and sensory function and amelioration of com-plications. Accumulating evidence has demonstrated that melatonin treatment could protect the neural tissues of the spinal cord from secondary injury after SCI. Melatonin is an indoleamine naturally produced by the pineal gland and other tissues. It can easily cross the blood-brain bar-rier and has been shown to have neuroprotective proper-ties in animal models with neurological injury, such as traumatic brain injury and SCI. We reviewed the potential mechanisms of melatonin treatment reducing SCI-relat-ed complications such as disruption of microcirculation, neurogenic bowel dysfunction, and circadian disorders.

Initial Experience with Mirabegron for the Treatment of Neurogenic Lower Urinary Tract Dysfunction

Background: Though anticholinergic drugs are considered the standard treatment for neurogenic detrusor overactivity, it is far from an ideal tool, because of their adverse effects such as Constipation or not respond sufficiently for a substantial proportion of patients. Recently mirabegron has become a commonly used overactive bladder medication in the general population, but few studies about mirabegron for the treatment of neurogenic detrusor overactivity. Objective: To evaluate the efficacy and safety of mirabegron for the treatment of neurogenic lower urinary tract dysfunction. Study Design: Prospective study. Methods: This prospective study included 13 adult patients with neurogenic lower urinary tract dysfunction as a result of spinal cord injury. All patients receiving mirabegron treatment (50 mg once daily) at least 6 weeks. The effective outcomes included the mean urine volume per catheterization, urinary incontinence episodes and Incontinence Specific Quality of Life Instrument. We monitored the blood pressure and heart rate to assess the cardiovascular safety, other adverse events were also recorded. Results: A total of 13 patients were included. After 6 weeks of treatment, all patients experienced a significant increase in the mean volume of per catheterization from 238.46 ± 65.43 ml to 327.69 ± 59.04 ml (p = 0.001). There is a significant reduction in the volume of urine leakage (463.85 ± 247.98 ml VS 180.00 ± 190.96 ml, p = 0.003) and incontinence episodes per 24 h (4.46 ± 2.03 VS 1.92 ± 1.50, p = 0.001). Significant improvement in mean Incontinence Specific Quality of Life Instrument was also found (p = 0.001). No patients reported dry mouth during the study, and the cardiovascular safety were acceptable. Conclusion: Mirabegron is safe and effective in the treatment of neurogenic lower urinary tract dysfunction. It might be a good choice for reducing the cessation of clean intermittent catheterization.
