The female tetraplegic: an admission of urological failure

Bladder management after spinal cord injury in the United States 1972 to 2005

PURPOSE

Studies have shown that bladder management with an indwelling catheter for patients with spinal cord injury is associated with more urological complications such as stones, urinary infection, urethral strictures and bladder cancer. However, little is known about actual bladder management for these patients in clinical practice.

MATERIALS AND METHODS

Using the National Spinal Cord Injury Database the bladder management method was determined at discharge from rehabilitation and at each 5-year followup period for 30 years.

RESULTS

At discharge from rehabilitation (24,762 patients) the selection of bladder management with a condom catheter decreased steadily from a peak of 34.6% in 1972 to a low of 1.50% in 2001. The use of clean intermittent catheterization increased from 12.6% in 1972 to a peak of 56.2% in 1991. Indwelling catheter use initially decreased from 33.1% in 1972 to 16.5% in 1991 but increased to 23.1% in 2001. Of 12,984 individuals with followup data those originally using an indwelling catheter for bladder management were unlikely to switch to another method, with 71.1% continuing to use an indwelling catheter at 30 years. Individuals using clean intermittent catheterization and condom catheterization at discharge home did not continue to use these methods with only 20% and 34.6% remaining on the same management, respectively.

CONCLUSIONS

With time bladder management with clean intermittent catheterization has increased in popularity. However, only 20% of patients initially on clean intermittent catheterization remained on this form of bladder management. More research on the safety of each of these methods needs to be performed to provide better guidance to aid with this decision.

Urological care of the spinal cord-injured patient

Spinal cord injury (SCI) is a catastrophic occurrence affecting the lives of 11,000 people in the United States every year. Urologic complications account for much of the morbidity associated with SCI and as much as 15% of the associated mortality. Spinal cord-injured patients are required to digest a plethora of self-management information during the emotionally and psychologically distressing period immediately following their injury. As a vital resource in the SCI patients' recovery process, it is crucial for the WOC nurse to have knowledge of the specialized needs of this population. This article reviews the effects of SCI on bladder function, discusses potential complications of the neurogenic bladder, and provides an overview of management options to assist the patient in adaptation and restoration of quality of life.

Management of the neurogenic bladder in the female patient

Management of the female patient with neurogenic bladder requires special considerations that are not seen with many male neurogenic bladder patients. Because of the unique challenges that certain women present, a disproportionate number of women end up with an indwelling catheter or continuously leak urine into a diaper. Other options for bladder management include intermittent catheterization and reconstruction, which, when used appropriately, can lead to significant improvements in urinary continence, quality of life, and patient independence. This article reviews the various options available today as well as several potential therapies that may be available in the future.

Neurogenic bladder management and cutaneous non-continent ileal conduit

STUDY DESIGN

Prospective monocentric follow-up study.

OBJECTIVES

To assess the results of cutaneous non-continent diversion for neurogenic bladder management.

SETTINGS

Department of Urology (Pitié-Salpétrière Hospital), Department of Neurological Rehabilitation (Raymond Poincaré Hospital), Assistance Publique-Hopitaux de Paris, University Paris VI and V.

METHODS

We reviewed the charts of 33 consecutive patients (19 women, 14 men), operated between 1979 and 1999. Twenty-one patients had spinal cord injury (SCI), four had multiple sclerosis, three had various forms of myelitis and five had central neurological diseases. Diversion was indicated for upper urinary tract protection (17), perineal dryness (14) and/or functional or social reasons (20). Before the operation, 20 of the 33 patients (60.6%) presented urologic complications related to bladder management, including triggered micturition, indwelling catheter or intermittent catheterization: urethrocutaneous fistula (4), complicated enterocystoplasty (2), watering pot perineum and severe decubitus ulcerations (14). Ileal conduit (also named ileoureterostomy) was performed alone for 19 patients (57.6%), and in combination with simultaneous cystectomy in 14 patients. We reviewed patient outcome and early and late complications.

RESULTS

Mean follow-up was 48 months (1 to 20 years). All problems related to catheters or incontinence had resolved. There were no deaths or early re-operations. Twelve patients (12 out of 33, 36%) had one or more peri-operative complication, including ileus (1), uretero-ileal anastomosis leak (1) and sepsis (1). During follow-up, four of the 19 patients who did not undergo cystectomy developed pyocystitis (3 secondary cystectomies performed between 6 and 56 months). All patients achieved perineal dryness.

CONCLUSIONS

The ileal conduit procedure is a safe and well-tolerated procedure in neurologically impaired patients. This procedure is suitable for most neurogenic patients with refractory lower urinary tract dysfunctions.

Pathogenesis of bacteriuria and infection in the spinal cord injured patient

Spinal cord injury (SCI) produces profound alterations in lower urinary tract function. Incontinence, elevated intravesical pressure, reflux, stones, and neurological obstruction, commonly found in the spinal cord-injured population, increase the risk of urinary infection. The overall rate of urinary infection in SCI patient is about 2.5 episodes per patient per year. Despite improved methods of treatment, urinary tract morbidity still ranks as the second leading cause of death in the SCI patient.SCI removes the ability of the pontine micturition center and higher centers in the brain to inhibit, control, or coordinate the activity of the vesicourethral unit. As a result, a patient with complete quadriplegia is typically unaware of bladder activity. Bladder contraction is accompanied by vesicosphincter dyssynergia instead of sphincter relaxation. It is widely accepted that intermittent catheterization, when compared with indwelling catheters, reduces the risk of urinary tract infection (UTI) in SCI patients and is the preferred method of bladder drainage in this patient population. Attempts at eliminating bacteriuria associated with indwelling or intermittent catheters have generally been unsuccessful. There is now appreciation of the fact that a creeping adherent biofilm of bacteria frequently ascends through the luminal and external surfaces of an indwelling catheter, often within 8 to 24 hours, leading to bacterial adherence to the bladder surface and correlating with symptomatic infection. The use of antimicrobial agents to clear or prevent bacteriuria in patients on indwelling or intermittent catheterization has had mixed success. Treatment for asymptomatic bacteriuria in SCI patients remains controversial. SCI patients with symptomatic urinary infections should be treated with the most specific, narrowest spectrum antibiotics available for the shortest possible time. Guidelines for selecting antimicrobial agents in SCI patients are similar to guidelines for the treatment of complicated urinary infections in the general population. Characteristics of the quinolones make them well suited to treating UTI in the SCI patient.

The vesical calculus

Bladder calculi account for 5% of urinary calculi and usually occur because of foreign bodies, obstruction, or infection. Males with prostate disease or previous prostate surgery and women who undergo anti-incontinence surgery are at higher risk for developing bladder calculi. Patients with SCI with indwelling Foley catheters are at high risk for developing stones. There appears to be a significant association between bladder calculi and the formation of malignant bladder tumors in these patients. Transplant recipients are not at increased risk for developing vesical calculi in the absence of intravesical suture fragments and other foreign bodies. Patients who undergo bladder-augmentation procedures using a vascularized gastric patch appear to be protected from vesicolithiasis, perhaps by the acidic environment. Ileum and colon tissues, however, are colonized by urease-producing organisms, producing an alkaline pH that promotes stone formation. Children remain at high risk for bladder-stone development in endemic areas. Diet, voiding dysfunction, and uncorrected anatomic abnormalities, such as posterior urethral valves and vesicoureteral reflux, predispose them to bladder-calculus formation. Finally, there are a number of techniques and modalities available to remove bladder stones. Relieving obstruction, eliminating infection, meticulous surgical technique, and accurate diagnosis are essential in their treatment.

Urological situation five years after spinal cord injury

OBJECTIVE

To evaluate bladder emptying methods and urinary tract problems five years after spinal cord injury (SCI).

MATERIAL AND METHODS

Neurological level, method of bladder emptying and urological investigations were retrieved from the records for all 165 patients admitted to our Centre for Spinal Cord Injured with a traumatic SCI sustained from 1984 to 1988.

RESULTS

A total of 77 patients with completed 5-year control were included in the final analyses. We found that 64% had suprasacral bladder dysfunction, while 23% had infrasacral bladder dysfunction. Plasma-creatinine was normal, both at the initial examination and the 5-year control. From the time in the SCI centre to the 5-year control a trend towards less intermittent catheterization and more use of abdominal pressure was observed. During the follow-up period nine patients (12%) experienced urinary calculi. Six bladder- stones were removed endoscopically. Five had kidney stones; three were left untreated, one was removed by extracorporeal shock wave lithotripsy and one by open surgery. Four patients (5%) had renograms with functional distribution outside the limits 40-60%. Three patients had bladder neck incision performed, one had a sacral anterior root stimulator implanted and one had a continent Kock reservoir. No sphincterotomies were performed. Fifty-one had received medicine to facilitate bladder emptying. Eighty-one percent had been treated for at least one urinary tract infection (UTI), 22% had 2-3 UTI/year, and 12% 4 or more UTI/year. Twelve percent had been on prophylactic low-dose antibiotics.

CONCLUSION

The final outcome regarding urological complications is satisfactory even with our conservative handling of the SCI individuals.
