Complications of clean intermittent catheterization in boys and young males with neurogenic bladder dysfunction.

PURPOSE: We evaluate the risk for urethral lesions and epididymitis in boys with neurogenic bladder dysfunction treated by clean intermittent catheterization (CIC) for a minimum of 10 years. MATERIALS AND METHODS: The medical records of 28 males with neurogenic bladder dysfunction followed from the start of CIC until the age of 15 to 20 years were reviewed. RESULTS: CIC had been performed for a median of 16 years (range 10 to 21). Overall CIC was used for 438 years (265 before and 173 after puberty). During 76% of the years a noncoated polyvinyl chloride catheter with lubrication was used and in 24% of years a hydrophilic coated polyvinyl chloride catheter was used. The catheter size was 12C or greater in 43% of the cases. Independence from self-catheterization occurred during 37% of the CIC years. Of the patients 19 experienced at least 1 episode of difficulty inserting the catheter and/or had macroscopic hematuria on a total of 42 occasions. Major urethral lesions were seen on cystoscopy in 7 patients on 9 occasions (5 false passages, 1 superficial recess, 2 meatal stenoses, 1 urethral stricture). Major urethral lesions were not associated with puberty and did not occur during self-catheterization or with use of catheters 12C or greater. Epididymitis was seen in only a 12 year-old boy. CONCLUSIONS: The overall rate of complications was low. The incidence of major urethral lesions did not increase during puberty. Self-catheterization and 12C catheter or greater seemed to be protective against major lesions.

[Reconstruction of lower urinary tract in patients with neurogenic bladder ].

Between 1988-1993 we performed lower urinary tract reconstruction in 30 patients with neurogenic bladder. The indications for surgery included urinary incontinence and/or upper urinary tract deterioration. 18 patients with a follow-up of longer than 18 months are reported. Continence was achieved in 15 of 16 patients and stabilization or improvement of the upper tracts in 17 of 18 patients. There was no mortality, and morbidity was the same as in similar series. Despite its complexity, lower urinary tract reconstruction in patients with neurogenic bladder brings major improvement in quality of life and in preservation of renal function. We recommend such operations in properly selected patients.

Follow-up of clean intermittent catheterization for children with neurogenic bladders.

Intermittent catheterization remains the primary method of treatment in the management of patients with neurogenic bladders such as those with meningomyelocele. In a follow-up of a previous study, we re-examined the urologic status of patients with neurogenic bladders continuing on a regimen of clean intermittent catheterization five years after the completion of the first study. Thirty-seven of the original 49 patients were available for follow-up, and no significant differences were found between those lost to follow-up and those included in this study. Among the patients re-evaluated, reflux remained unchanged or improved in most patients, renal function was maintained, and the urinary tract infection rate remained low. Additionally, continuation of an intermittent catheterization program does provide independence and social continence in most young adults with meningomyelocele. We conclude that a long-term intermittent catheterization program is associated with stable reflux status, renal function, and infection rate, and that compliance with a catheterization program can result in improved social continence and independence.

The impact of the artificial urinary sphincter in the neurogenic bladder on the upper urinary tracts.

The charts and x-rays of 120 neurogenic bladder patients who underwent artificial sphincter implantation for treatment of urinary incontinence between 1973 and 1984 were reviewed retrospectively. Patients were followed for 3 to 130 months (average 36.8 months). The upper urinary tracts remained unchanged in 108 patients (90 per cent). Renal growth in children was undisturbed. Transient hydroureteronephrosis occurred in 8 patients (6.7 per cent) and progressive hydroureteronephrosis occurred in 4 (3.3 per cent). A total of 26 patients with vesicoureteral reflux (39 ureters) underwent ureteral reimplantation. Our results indicate that implantation of the artificial urinary sphincter in neurogenic bladder patients has minimal adverse impact on the upper urinary tracts, followup should be long-term and should include an IVP, outflow obstruction should be eliminated preoperatively by means of external sphincterotomy in male patients and bladder flap urethroplasty in female patients, similarly, adequate emptying of the bladder always must be assured during followup, if hydroureteronephrosis is detected early appropriate treatment can restore normal upper tracts, the presence of previously damaged upper tracts without evidence of obstruction is not a contraindication for artificial sphincter implantation and an antireflux operation in combination with artificial sphincter implantation is feasible.

Evaluation of cranberry supplement for reduction of urinary tract infections in individuals with neurogenic bladders secondary to spinal cord injury. A prospective, double-blinded, placebo-controlled, crossover study.

OBJECTIVE: To determine the effectiveness of cranberry supplement at preventing urinary tract infections (UTIs) in persons with spinal cord injury (SCI). DESIGN: A prospective, double-blinded, placebo-controlled, crossover study. PARTICIPANTS: 21 individuals with neurogenic bladders secondary to SCI. MAIN OUTCOME MEASURES: Favorable or unfavorable response of cranberry supplement vs placebo on urinary bacterial counts and white blood cell (WBC) counts and the combination of bacterial and WBC counts. METHODS: Individuals with neurogenic bladders due to SCI were recruited and randomly assigned to standardized 400-mg cranberry tablets or placebo 3 times a day for 4 weeks. After 4 weeks and an additional 1-week "washout period," participants were crossed over to the other group. Participants were seen weekly, during which a urine analysis was obtained. UTI was defined as significant bacterial or yeast colony counts in the urine and elevated WBC counts (WBC count > or = 10 per high power field) in centrifuged urine. Participants with symptomatic infections were treated with appropriate antibiotics for 7 days and restarted on the cranberry tablet/ placebo after a 7-day washout period. Urinary pH between the cranberry and placebo groups was compared weekly. Data were analyzed using the Ezzet and Whitehead's random effect approach. RESULTS: There was no statistically significant treatment (favorable) effect for cranberry supplement beyond placebo when evaluating the 2 treatment groups for bacterial count, WBC count, or WBC and bacterial counts in combination. Urinary pH did not differ between the placebo and cranberry groups. CONCLUSION: Cranberry tablets were not found to be effective at changing urinary pH or reducing bacterial counts, urinary WBC counts, or UTIs in individuals with neurogenic bladders. Further long-term studies evaluating specific types of bladder management and UTIs will help to determine whether there is any role for the use of cranberries in individuals with neurogenic bladders.

Bacteriuria management and urological evaluation of patients with spina bifida and neurogenic bladder: a multicenter survey.

PURPOSE: We assessed how groups at spina bifida clinics evaluate and manage the urinary tract in patients with spina bifida, neurogenic bladder and bacteriuria. MATERIALS AND METHODS: A survey was mailed to all 169 clinics listed by the Spina Bifida Association of America. Survey items addressed baseline and surveillance evaluation, criteria used to assess urinary tract health and approaches to treatment in patients with spina bifida and neurogenic bladder. RESULTS: Of the 169 clinics personnel at 59 (35%) responded to the survey. Almost half of the respondents had an established protocol or standard of care. At most clinics the use of ultrasound (93%), voiding cystourethrograms (85%) and urodynamic testing (76%) was supported but not renal isotopic studies (14%) or excretory urograms (2%) for baseline evaluation. At all clinics ultrasound was supported for routine surveillance but there was no consensus for other imaging modalities. Assessment of clinic approaches to the evaluation and management of bacteriuria demonstrated variable results, although at most clinics fever, flank pain, dysuria, and changes in urinary pattern were identified as being consistent with true infection. Groups at clinics following their protocol or standard of care showed no significant differences in their approach compared to those at clinics lacking a protocol or standard of care. CONCLUSIONS: No consensus exists for the evaluation and management of bacteriuria in patients with spina bifida and neurogenic bladder at clinics specializing in the care of such patients, even at those with established standards of care. A clear need exists for an established, national set of evidence based guidelines to assist medical decision making in this high risk population and, thus, improve care.

A multicenter placebo-controlled, double-blind trial of urapidil, an alpha-blocker, on neurogenic bladder dysfunction.

OBJECTIVES: To assess the efficacy of urapidil, an alpha-blocker, on neurogenic bladder dysfunction in a placebo-controlled, double-blind trial. METHODS: 149 patients were randomly assigned to receive a placebo or 60 mg/day of urapidil for 4 weeks. The evaluation of efficacy included changes in urinary symptom scores and the results of a pressure/flow study. RESULTS: There were significant intergroup differences with regard to straining and the sum of urinary symptom scores, with the urapidil group showing marked improvements (p = 0.016 and p = 0.011, respectively). In the urapidil group, the average and maximum flow rates were unchanged, but the residual urine volume decreased significantly (p < 0.001) as compared with the baseline value. The pressure at maximum flow and the minimum urethral resistance decreased significantly (p = 0.040 and p = 0.040, respectively) in the urapidil group, and there was a significant (p = 0.005) intergroup difference with regard to pressure at maximum flow. There was also a significant (p < 0.001) inter-group difference with regard to the overall therapeutic effect. Side effects were noted in 2 patients treated with urapidil and 6 in the placebo group. CONCLUSION: Urapidil is effective for the treatment of voiding dysfunction in patients with neurogenic bladder.

[Neurogenic bladder dysfunction due to spina bifida and sacral dysgenesis manifested itself in middle age. Report of a case].

Congenital neurogenic bladder dysfunction with spina bifida and sacral dysgenesis manifested itself at middle age is reported. A 48-year-old male who had urinary retention and suprapubic cystostomy one year and a half before in another hospital was seen, asking for removal of the cystostomy. He had never had any neurologic or bladder dysfunction in his childhood and adulthood. X-ray examination revealed a bifid spine and sacral dysgenesis, bilateral hydronephrosis, bilateral VUR and urethral stricture. Uroflowmetry showed a severe dysuric pattern (voided volume 5 ml, residual urine 230 ml) and the cystometrogram revealed a hyperactive bladder. Optical urethrotomy for stricture yielded some improvement i.e. recovery of voluntary voiding with large amount of residual urine. TUR of the bladder neck resulted in almost complete voiding. Cohen's antireflux operation yielded favorable improvement of hydronephrosis. The bladder and renal function remained favorable in the follow-up period of about two years. The clinical course of this patient suggested that his bladder dysfunction was due to late manifestation of congenital neurogenic bladder.

Epidural spinal cord stimulation for the treatment of neurogenic bladder.

The effect of percutaneous epidural spinal cord stimulation on neurogenic bladder has been evaluated on the basis of objective clinical and urodynamic criteria. Seven patients suffering from stable bladder and sphincter dysfunction due to spinal cord diseases of different causes of non-evolutive nature were examined. In some of them chronic pain or substantially improved micturition in six of our seven patients. Complete or almost complete relief of bladder spasticity, marked increase of bladder capacity, and reduction or abolition of residual urine were recorded. The beneficial effect on bladder and sphincter function is strictly dependent on the stimulation, though it can outlast it. It requires some weeks to reach its maximum. It is still obtained after 22 months of treatment (longest present follow-up). No changes of straital activity and detrusor reflex were produced by spinal cord stimulation in two additional patients, treated for chronic pain but having intact bladder function.

The use of intravesical oxybutynin chloride in children with neurogenic bladder.

Intravesical oxybutynin chloride was administered to 10 children with neurogenic bladder (myelomeningocele in 9 and imperforate anus in 1) and urinary incontinence refractory to regimens of intermittent catheterization and oral anticholinergic medication. Therapy consisted of instillation of 5 mg. crushed oxybutynin chloride in 10 cc sterile saline twice daily. Of the children 5 (50%) became completely dry day and night, 3 (30%) achieved daytime continence alone, and 2 did not improve clinically and remained in diapers. Urodynamic study revealed increases in bladder capacity up to 335% over baseline and decreases of maximum filling pressures to 63%. No local or systemic side effects were noted. Surgical bladder augmentation was avoided in those who clinically responded to this therapy.

Further observation on the denervation supersensitivity of the urethra in patients with chronic neurogenic bladders.

The response of the urethra in patients with chronic neurogenic bladders to autonomic stimulation was investigated by urethral pressure profile. A consistent supersensitivity to alpha-adrenergic stimulation was documented. Experiments with various autonomic blocking drugs confirmed that this response is alpha-adrenergically mediated via the short neuron system. The results appear to offer pharmacological evidence for the recently evolving intricate innervation pattern of the urethra including its distal portion, where the alpha-adrenergic system is believed to be important.

Patient perspective of long-term outcome of augmentation cystoplasty for neurogenic bladder.

OBJECTIVES: Although the urologic outcomes of augmentation cystoplasty for neurogenic bladder dysfunction are well known, additional information about the patient perspective is needed. The aim of this study was to assess patient perspective using a standardized questionnaire. METHODS: Fifty-nine patients, who had undergone augmentation enterocystoplasty as part of reconstruction mainly to correct hyperactive bladders and incontinence, were subjected to a questionnaire after a median of 76.1 postoperative months. The questionnaire addressed medications, catheterization, incontinence, bowel dysfunction, and satisfaction with urinary tract management. The urologic outcomes regarding upper and lower tract changes, complications, and reinterventions were documented as well. RESULTS: The patients experienced a significant increase in bladder capacity and decrease in pressure at capacity (P < 0.0001). Normal upper tracts remained normal and there was either improvement or stabilization of hydronephrosis. Twenty-four patients (40.6%) had one or more complications, with 21 requiring reinterventions. Twenty-five percent of patients required the reintervention within the first 25 months, and the median time to reintervention was almost 10 years. Thirty-five patients took medications such as anticholinergics, antidiarrheals, or antibiotics. Fifty-six patients were treated with clean intermittent catheterization (CIC) at a mean interval of 4.6 hours. Seven patients had some difficulty with CIC. Thirty-nine patients (67%) were dry, and 17 had mild and 3 severe incontinence. Eleven patients (18.6%) reported bowel dysfunction, although 7 had it preoperatively. Almost all patients were very satisfied with their urologic management. CONCLUSIONS: The high degree of patient satisfaction attests to the value of the procedure. The complication and reintervention rates underscore the importance of long-term follow-up.

Augmented enterocystoplasty for neurogenic bladder associated with renal transplantation: appearance on Tc-99m MAG3 renal transplant scan.

Enterocystoplasty (bladder augmentation) is a method of increasing bladder capacity in patients with small or neurogenic bladders in order to prevent vesicoureteral reflux. In patients with poorly compliant bladders, enterocystoplasty, which consists of a segment of detubularized small bowel or a portion of the stomach attached to the bladder, often helps to reduce the intravesicular pressures, thus reducing the likelihood of infection. It is also useful in treating bladder dysfunction in children with end-stage renal disease who require renal transplantation. Radiographic evaluation of patients with a renal transplant and augmented bladder often can be confusing, and may suggest a urine leak or hematoma. We report a patient with a renal transplant, bladder augmentation, and rising serum creatinine who underwent renal scintigraphy and ultrasonography.

[Functional reinnervation in patients with a diagnosis of lower motor neuron neurogenic bladder: prognostic and therapeutic considerations].

OBJECTIVE: To evaluate bladder and urethral sphincter reinnervation mechanisms during long-term follow-up in patients with lower motor neuron neurogenic bladder following neurological surgical injury. METHODS: A urodynamic study was conducted in 30 patients (21 male and 9 female; mean age 53.4 years) with lower motor neuron neurogenic bladder dysfunction arising from neurological injury sustained during surgery. The protocol included cystometry and periurethral electromyography (EMG) at 3, 6, 9, 12 months and once a year for 7 years, and videocystography at 3, 12 months and once a year for 7 years. Functional parasympathetic (detrusor) reinnervation criteria were cystometric. Functional sympathetic (bladder neck) reinnervation criteria were cystographic. Functional pudendal (periurethral sphincter) reinnervation criteria were electromyographic (increase of polyphasic and long amplitude and/or long time potentials). RESULTS: Detrusor reinnervation was demonstrated in 6 male patients (20%) with an average period of 44.6 months. Pudendal reinnervation was demonstrated in 17 patients (77.2%) with an average period of 17.6 months. EMG potentials were polyphasic in 17 cases and long amplitude/long time potentials in 3 cases. Sympathetic reinnervation was demonstrated in one patient (16.6%) at 60 months. CONCLUSIONS: Functional pudendal reinnervation of the periurethral sphincter was more frequent and was demonstrated earlier than reinnervation in vegetative elements (parasympathetic and sympathetic). Parasympathetic reinnervation had long-term therapeutic implications. Ongoing urodynamic assessment in patients with lower motor neuron neurogenic bladder following abdominoperineal resection or intervertebral disc prolapse surgery is warranted. Sympathetic reinnervation was scanty and was demonstrated later in relation to distal postganglionic fibers.

[Therapeutic effect of Robaveron tablet (KN-7) on neurogenic bladder].

Therapeutic effect of Robaveron Tablet (KN-7) was studied on 128 patients suffering from neurogenic bladder. Robaveron Tablet was administered 6 tablets daily for 3 weeks. The effect was evaluated by the residual urine, subjective symptoms, cystometric findings, urethral pressure profile and uroflowmetry. Remarkable decrease of residual urine was observed regardless of position of injury. The pressure amplitude defined as the difference between the maximum voiding pressure and the maximum resting pressure increased on any group of neurogenic bladder. The effectiveness, rated as moderately improved or better was 76.9% for brain disorders, 58.3% for upper motor neuron lesion and 75.7% for lower motor neuron lesion of spinal injuries, 58.3% for peripheral nervous injuries and 100% for others. No remarkable abnormality was observed in the results of side effects or clinical laboratory tests.

Correlation of upper and lower urinary tract function in patients with neurogenic bladder: evaluation using simultaneous measurement of cystometry and diuresis renography with full and empty bladder.

Diuresis renography and water filling cystometry were simultaneously performed with the bladder full and with the bladder empty. The findings of diuresis renography with a full bladder were compared with those of diuresis renography with an empty bladder, in 9 patients (4 male and 5 female, mean 24.4 years old) with neurogenic bladder dysfunction. According to O'Reilly's classification, the findings of diuresis renography with a full bladder were significantly worse than those of diuresis renography with an empty bladder, regardless of cystometry patterns and bladder compliance. These results suggest that in patients with neurogenic bladder dysfunction, a full bladder in itself can cause deterioration of the upper urinary tracts, regardless of bladder pressure and bladder compliance.

Incontinent ileovesicostomy in the management of neurogenic bladder dysfunction.

AIMS: To report outcome and urodynamic follow-up of incontinent ileovesicostomy in quadriplegic patients with neurogenic bladder. METHODS: Seven patients (five male, two female; mean age, 33.7 yr) with neurogenic bladder underwent ileovesicostomy for management of leakage or complications of chronic catheter drainage. Five had chronic indwelling catheters: three suprapubic and two urethral. Preoperatively, all had upper tract evaluation and videourodynamics. All seven patients had detrusor hyperreflexia. Preoperative detrusor leak point pressures averaged 42.7 cm H(2)O. Two females had intrinsic sphincteric deficiency from prolonged Foley catheter drainage. Ileovesicostomy involves isolation of a 15-20-cm segment of terminal ileum. The proximal 6-8 cm of this segment is opened on the antimesenteric border. The dome of the bladder is opened widely in a transverse manner and the proximal portion of the bowel is sutured onto the bladder. The distal portion of the ileum remains tubularized and becomes the stoma. RESULTS: There were no intraoperative complications. Operative time averaged 159 minutes. Associated procedures included removal of bladder calculus (n = 1), pubovaginal sling (n = 2), and Marshall Marchetti Krantz suspension (n = 1). Mean blood loss was <200 cc in six patients. Mean hospital stay was 8 days. Complications in two patients included: fascial stenosis requiring stoma revision (n = 1), wound infection (n = 1), and postoperative ileus (n = 1). Mean follow-up was 37.4 months. Postoperatively, mean detrusor leak point pressures were 16.7 cm H(2)O (P = 0.0061). Patient satisfaction is high with only one complaint of occasional difficulty fitting the appliance. CONCLUSIONS: Ileovesicostomy is an effective method of urinary drainage in quadriplegic patients. Detrusor leak point pressures were lowered, and upper tracts were preserved. No long-term complications were encountered.
