Social and personal consequences of acquired bowel dysfunction for persons with spinal cord injury

BACKGROUND: Traditional literature regarding acquired bowel dysfunction for persons with spinal cord injury (SCI) has focused on clinical assessments of bowel dysfunction and bowel management programs. These studies make reference to the effects of bowel dysfunction on quality of life (QOL), but none systematically study the relationship. This study develops 4 scales that measure impediment to community integration (ICI) due to bowel dysfunction and then examines the relationship between bowel dysfunction, ICI, and QOL. METHODS: A structured telephone survey was conducted with a convenience sample of 103 SCI consumers. Survey questions documented bowel dysfunction (ie, severity and number of accidents), bowel management (ie, how often bowels are evacuated), ICI, and satisfaction with 4 life domains. RESULTS: Correlation analyses showed that subjective bowel dysfunction severity and number of days per month a respondent had to stay home because of lack of bowel control were associated with barriers to personal relationships, feelings about self, and home life. Also, the number of bowel accidents per month was associated with feelings about self. ICI scales were shown to be related to lower levels of satisfaction with free time, friendships, family life, and life in general. No statistically significant relationships were found between bowel dysfunction and satisfaction with life. CONCLUSION: Bowel dysfunction is a barrier to community integration and is related to low levels of life satisfaction. Also, it is possible to quantify ICI related to bowel dysfunction. Educational programs can reduce the stigma associated with bowel dysfunction. Further research into the intricate relationships between bowel problems, barriers to participation in the community, and life satisfaction is needed.     

Bladder management methods and urological complications in spinal cord injury patients

Background:

The optimal bladder management method should preserve renal function and minimize the risk of urinary tract complications. The present study is conducted to assess the overall incidence of urinary tract infections (UTI) and other urological complications in spinal cord injury patients (SCI), and to compare the incidence of these complications with different bladder management subgroups.

Materials and Methods:

545 patients (386 males and 159 females) of traumatic spinal cord injury with the mean age of 35.4±16.2 years (range, 18 – 73 years) were included in the study. The data regarding demography, bladder type, method of bladder management, and urological complications, were recorded. Bladder management methods included indwelling catheterization in 224 cases, clean intermittent catheterization (CIC) in 180 cases, condom drainage in 45 cases, suprapubic cystostomy in 24 cases, reflex voiding in 32 cases, and normal voiding in 40 cases. We assessed the incidence of UTI and bacteriuria as the number of episodes per hundred person-days, and other urological complications as percentages.

Results:

The overall incidence of bacteriuria was 1.70 / hundred person-days. The overall incidenceof urinary tract infection was 0.64 / hundered person-days. The incidence of UTI per 100 person-days was 2.68 for indwelling catheterization, 0.34 for CIC, 0.34 for condom drainage, 0.56 for suprapubic cystostomy, 0.34 for reflex voiding, and 0.32 for normal voiding. Other urological complications recorded were urethral stricture (n=66, 12.1%), urethritis (n=78, 14.3%), periurethral abscess (n=45, 8.2%), epididymorchitis (n=44, 8.07%), urethral false passage (n=22, 4.03%), urethral fistula (n=11, 2%), lithiasis (n=23, 4.2%), hematuria (n=44, 8.07%), stress incontinence (n=60, 11%), and pyelonephritis (n=6, 1.1%). Clean intermittent catheterization was associated with lower incidence of urological complications, in comparison to indwelling catheterization.

Conclusions:

Urinary tract complications largely appeared to be confined to the lower urinary tract. The incidence of UTI and other urological complications is lower in patients on CIC in comparison to the patients on indwelling catheterizations. Encouraging CIC; early recognition and treatment of the UTI and urological complications; and a regular follow up is necessary to reduce the medical morbidity.     

Bladder cancer in patients with spinal cord injury

OBJECTIVE: The incidence of bladder cancer in spinal cord injury (SCI) is 16 to 28 times higher than that in the general population. The objective of this study was to investigate the characteristics of bladder cancer that are unique to the SCI population. DESIGN: Retrospective review. METHODS: The charts of 16 patients diagnosed with bladder cancer from 1982 to 2001 were reviewed for type of cancer, exposure to risk factors, presenting symptoms, and survival time. RESULTS: The presenting manifestations were gross hematuria in 14 patients, papillary urethral growth in 1 patient, and acute obstructive renal failure in 1 patient. The diagnosis was made on initial cystoscopic evaluation in 16 patients; 3 patients required further evaluation. Eight of the 11 screening cytologies were suspicious for a malignancy prior to the diagnosis. Seven patients had transitional cell carcinoma, 6 patients had squamous cell carcinoma (SCCA), and 3 patients had both. The bladder wasmanaged with chronic indwelling catheter in 12 patients. Nine patients died of bladder cancer metastases and the remaining 3 patients died of other causes. Six patients survived 5 years or more; 4 were still alive at the completion of this study. CONCLUSION: Gross hematuria in individuals with SCI warrants aggressive assessment for bladder cancer. Chronic indwelling catheter, smoking, and renal and bladder stones are important risk factors for cancer. The incidence of SCCA in the SCI popullation is much higher than in the general population. Cystoscopic and cytologic evaluation in patients with advanced disease may fail to confirm the diagnosis in a high proportion of patients.     

Bladder cancer in patients with spinal cord injuries

OBJECTIVE: To evaluate the age-standardized incidence rate of bladder cancer in patients with spinal cord injury (SCI) and the overall risk for this population. PATIENTS AND METHODS: We reviewed 1334 patients with SCI whose dates of SCI, or first attendance at our centre, were between 1940 and 1998. The length of follow-up was calculated for each patient and age-specific incidence rates of bladder cancer calculated using 5-year age bands. This was used to calculate the overall incidence rate, using direct standardization with the European standard population. The cancers were analysed histochemically to characterize the phenotype. RESULTS: The 1324 patients contributed a total of 12 444 person-years of follow-up. There were four cases of bladder cancer, giving an age-standardized incidence rate of 30.7 per 100 000 person-years. Histochemistry showed areas were positive for cytokeratin 14, which was also positive in the undifferentiated areas. Immunohistochemical staining was positive for cytokeratin 14 and consistently negative for cytokeratin 20, suggesting a pure squamous phenotype. CONCLUSIONS: The age-standardized incidence of invasive bladder cancer in patients in our SCI unit is not statistically different from that of the general population. However, the incidence of invasive bladder cancer in the present study appears to be lower than that reported in other series. Histochemical analysis confirmed a squamous cell phenotype in these tumours.     

Augmentation enterocystoplasty for the management of voiding dysfunction in spinal cord injury patients

A total of 12 spinal cord injury adults underwent augmentation enterocystoplasty for treatment of a high pressure neurogenic bladder. These patients suffered from urinary incontinence, recurrent urinary tract infection, upper tract deterioration and severe autonomic dysreflexia. A sigmoid colon segment fashioned into a cup-patch was used in 11 patients and detubularized cecum was used in 1. The artificial urinary sphincter was implanted in 3 patients at augmentation enterocystoplasty and in 1 after enterocystoplasty. After a mean followup of 15 months all patients were continent on clean intermittent self-catheterization, the upper tract had remained stable or had improved and the symptoms of autonomic dysreflexia had disappeared. A third of the patients are on maintenance antibiotic therapy to control bacteriuria.     

Clinical evaluation and management of neurogenic bowel after spinal cord injury

OBJECTIVES: To assess the state of the neurological bowel in spinal cord injured (SCI) patients, design and apply a program for the comprehensive management of neurogenic bowel and evaluate outcome. SETTING: Out-patient in a Rehabilitation Service. SUBJECTS: Thirty-eight SCI patients, 12 (32%) with complete lesions of more than 5 years duration. DESIGN: Observational, longitudinal and prospective. Pre and post intervention. METHOD: Pre and post SCI intestinal function was evaluated clinically prior to beginning program. The presence of GI symptoms were studied. Laboratory work-up included colonic transit time (CTT), anorectal manometry and recto-colonoscopy. An intestinal program was designed, in order to achieve an effective and efficient evacuation in a predictable and socially acceptable time, to avoid short and long term complications and eliminate inadequate intestinal evacuation habits. OUTCOME MEASURES: Pre and post SCI difficulty in intestinal evacuation (DIE) was increased (from 2.6% to 26.3%). The most frequent GI symptom was abdominal distention (53%). Colonic inertia was present in 49% of CTT, internal anal sphincter pressure was normal or increased in 77% and rectoanal inhibitory reflex was present in 88%. With the intestinal program, the incidence of DIE was reduced to 8.8%, manual extraction (ME) was reduced from 53% to 37%. Excellent and good results were obtained in 56% of the patients. CONCLUSION: The proposed intestinal program is effective in the rehabilitation of SCI patients with neurogenic bowel. It is essential to initiate these physiological and safe procedures as soon as possible after sustaining the injury; this will lead to better results and to the elimination of inadequate intestinal maneuvering in the future Spinal Cord (2000) 38, 301 - 308.

Cost-effectiveness of transanal irrigation versus conservative bowel management for spinal cord injury patients

STUDY DESIGN: Cost-effectiveness analysis following international guidelines and taking the societal viewpoint. OBJECTIVES: To estimate the cost-effectiveness of transanal irrigation using a self-administered irrigation system when compared with conservative bowel management. SETTING: A randomized clinical trial was conducted at five spinal centres situated in Denmark, Germany, Italy, United Kingdom and Sweden. Estimates of resources and unit costs were made for the German health care system. METHODS: Efficacy outcomes were drawn from a randomized controlled trial conducted in 2003-2005. Adult spinal cord-injured patients with neurogenic bowel dysfunction were randomized to 10 weeks with either transanal irrigation using Peristeen Anal Irrigation or to conservative bowel management. Costs were calculated based on results from the clinical trial and on 24 interviews conducted in Germany. Unit costs were obtained from the Federal Statistical Office Germany and product list prices. RESULTS: When comparing outcome measures at termination, transanal irrigation significantly reduced symptoms of neurogenic bowel dysfunction. Product-related costs were higher for transanal irrigation using the self-administered system; however, costs for a carer to help with bowel management and changes/washing due to leakage were lower. For transanal irrigation, costs associated with urinary tract infections and patient time spent were reduced. Thus, the total cost to society is lower when patients use transanal irrigation. The results were shown to be robust in the sensitivity analysis. CONCLUSION: Transanal irrigation using a self-administered system reduces symptoms of neurogenic bowel dysfunction and results in a lower total cost to society than conservative bowel management. SPONSORSHIP: The study was supported by Coloplast A/S.     

Bladder management and risk of bladder stone formation in spinal cord injured patients

PURPOSE: We determined by statistical analysis whether method of management is associated with risk of bladder stone formation in spinal cord injured patients. MATERIALS AND METHODS: A retrospective cohort study was performed of 457 patients admitted to Stoke Mandeville Hospital Spinal Injuries Center between 1985 and 1990 with more than 6 months of followup. Analysis included Cox regression and Poisson regression. RESULTS: Relative to those patients treated with intermittent self-catheterization, the hazard ratio was 10.5 (p <0.0005, 95% confidence interval 4.0-27.5) for patients with suprapubic catheters and it was 12.8 (p <0.0005, 95% confidence interval 5.1-31.9) for those with indwelling urethral catheters. The absolute annual risk of stone formation in patients with a catheter was 4% compared with 0.2% for those on intermittent self-catheterization. However, having formed a stone, the risk of forming a subsequent stone quadrupled to 16% per year. Bladder stones were no more likely to form in patients with suprapubic catheters compared to those with indwelling urethral catheters (hazard ratio 1.2, p = 0.6). CONCLUSIONS: In spinal cord injured patients long-term catheterization is associated with a substantial increased risk of bladder stone formation. This increased risk occurs independently of age, sex and injury level. Degree of injury (complete or incomplete) was considered in the model. Catheter type (suprapubic or urethral) did not change this risk significantly if at all.     

Bladder and sphincter behavior in patients with spinal cord lesions

To ascertain the relationship between the clinical neurological level, and bladder and sphincter behavior, the video-urodynamic studies of 489 patients with spinal cord lesions due to a variety of causes were retrospectively analyzed. Patients were classified based on the clinical neurological level, etiology of the lesion and presence or absence of signs of sacral cord involvement. Urodynamic findings were classified as either detrusor hyperreflexia, detrusor-external sphincter dyssynergia, detrusor areflexia or normal. The results indicate that although there was a general correlation between the neurological level of injury and the expected vesicourethral function, it was neither absolute nor specific. For example, 20 of 117 cervical cord lesions had detrusor areflexia, 42 of 156 lumbar cord lesions had detrusor-external sphincter dyssynergia and 26 of 84 sacral cord had either detrusor hyperreflexia or detrusor-external sphincter dyssynergia. However, if one considers the presence of neurological abnormalities, 84% of the suprasacral cord lesions with detrusor areflexia have sacral cord signs. In contrast, all suprasacral cord lesions with no evidence of sacral cord involvement have either detrusor hyperreflexia or detrusor-external sphincter dyssynergia. The positive predictive value for positive sacral cord signs and detrusor areflexia was 87%. The positive predictive value for negative sacral cord signs and detrusor hyperreflexia/detrusor-external sphincter dyssynergia was 81%. These data suggest that the clinical neurological examination alone is not an adequate barometer to predict neurourological dysfunction and that video-urodynamic evaluation provides a more precise diagnosis for each patient.     

Bladder outlet surgery in men with spinal cord injury

The effect of bladder outlet surgery on voiding ability, changes in the upper urinary tract and urinary infections was studied in 51 men with spinal cord injury. In 24 patients reoperation was required after varying periods of time to achieve satisfactory bladder voiding. Eight of the 22 men who had undergone external sphincterotomy had constant dribbling of urine postoperatively. Dilation of the upper urinary tract was completely reversed or reduced in 13 of 18 patients following the primary operation on the bladder outlet. Vesico-ureteric reflux was found in 6 of the 8 men in whom deterioration of the upper urinary tract persisted after the initial operation or appeared during the follow-up years. Bacteriuria usually persisted, despite bladder outlet surgery, but febrile attacks of urinary tract infection ceased or became less frequent in 15 of the 22 patients who had experienced such episodes preoperatively.     

Bladder training in patients with spinal cord injury.

Immediately following severe injury to the spinal cord or conus medullaris, there is a stage of flaccid paralysis of the bladder. The smooth muscle of the detrusor and rectum is affected. Drainage of the bladder is very important in the early care of such patients. From August 1989 to August 1990, 55 spinal cord injury patients were studied on admission to our department. The current bladder training method used for these patients is presented. A patient was deemed to have been successfully bladder trained when catheter-free, continent, and able to consistently maintain a residual volume of 100 mL or less with the aid of tapping and compression. On discharge 45 patients (82%) were successfully bladder trained, 8 (15%) employed a regimen of clean intermittent self-catheterization, and 2 went home/institutional care with an indwelling catheter. The material presented is applicable to any type of neurogenic bladder dysfunction.     

Recommendations for evaluation of neurogenic bladder and bowel dysfunction after spinal cord injury and/or disease

Objective: To provide an overview of clinical assessments and diagnostic tools, self-report measures (SRMs) and data sets used in neurogenic bladder and bowel (NBB) dysfunction and recommendations for their use with persons with spinal cord injury /disease (SCI/D).

Methods: Experts in SCI/D conducted literature reviews, compiled a list of NBB related assessments and measures, reviewed their psychometric properties, discussed their use in SCI/D and issued recommendations for the National Institutes of Health (NIH), National Institute of Neurological Disorders and Stroke (NINDS) Common Data Elements (CDEs) guidelines.

Results: Clinical assessments included 15 objective tests and diagnostic tools for neurogenic bladder and 12 for neurogenic bowel. Following a two-phase evaluation, eight SRMs were selected for final review with the Qualiveen and Short-Form (SF) Qualiveen and the Neurogenic Bowel Dysfunction Score (NBDS) being recommended as supplemental, highly-recommended due to their strong psychometrics and extensive use in SCI/D. Two datasets and other SRM measures were recommended as supplemental.

Conclusion: There is no one single measure that can be used to assess NBB dysfunction across all clinical research studies. Clinical and diagnostic tools are here recommended based on specific medical needs of the person with SCI/D. Following the CDE for SCI studies guidelines, we recommend both the SF-Qualiveen for bladder and the NBDS for bowel as relatively short measures with strong psychometrics. Other measures are also recommended. A combination of assessment tools (objective and subjective) to be used jointly across the spectrum of care seems critical to best capture changes related to NBB and develop better treatments.     

Bladder hypocompliance in the spinal cord injury population

To determine the incidence and effects of low bladder compliance on the upper urinary tracts in spinal cord injury patients, we evaluated the last 254 patients during a 3-year period who underwent a complete urodynamic study, along with an excretory urogram and/or renal ultrasound. Compliance was determined at 100 cc volume. A compliance number of 20 or less was considered low. Of the 254 patients 43 (17 per cent) had low compliant bladders by our definition. Hydronephrosis was present in 56 of the 84 renal units (64 per cent) and reflux was present in 39 (46 per cent). These results are in sharp contrast to the normal compliant group in which 21 per cent of 418 renal units had hydronephrosis and only 6 per cent had reflux. Of the 254 patients over-all 44 had lower motor neuron lesions as determined by no bulbocavernosus reflex as well as a denervated external sphincter; 22 of these 44 patients (50 per cent) had low compliant bladders. Conversely, among the 210 patients with suprasacral lesions only 21 (10 per cent) had low compliant bladders. In conclusion, the development of a low compliant bladder in spinal cord injury patients is not an uncommon event and places the upper urinary tracts at great risk. All attempts must be directed toward maintaining low detrusor pressures, and these patients must have adequate and frequent followup evaluation.
