The status of the urinary tract in a survey of 92 cases with neurogenic bladder.

Since 1973 intermittent catheterisation was introduced in our centre and this practically eliminated pathology of the urethra. More than half of the patients had a high and complete lesion. It is our impression that 5 years following injury more than half of the patients preserved a normal upper urinary tract; however, only 39 of the 92 patients had a follow-up of over 5 years. Nephrolithiasis was rare in comparison to other reports in spite of belonging to the stone belt area. Complications of the lower urinary tract including a 10 per cent incidence of vesico-ureteric reflux were compatible with other series. Narrowing of the external sphincter on voiding cystogram should be substantiated by a profile pressure record. One female patient is a candidate for ileal conduit. Most of the patients have some form of erection but the data on ejaculation should be accepted with reserve. Two patients in this series died more than 10 years after injury, one due to a myocardial infarction and the other due to chronic renal failure following secondary amyloidosis.

Management of neurogenic bladder dysfunctions following acute traumatic cervical central cord syndrome (incomplete tetraplegia) [proceedings].

Based on the experience to date with central cord syndrome, most or all of the following conditions should be present before considering transurethral sphincterotomy: (1) minimal neurological recovery within 6 months of injury; (2) four plus spasticity in patients over the age of 50 years; (3) prolonged intermittent catheterisation over 6 months, with persistent residual urine over 300 ml; (4) persistent and repeated use of diazepam, dantrolene sodium to control pelvic floor spasticity; (5) demonstrable detrusor-sphincter dyssynergia.

Towards a catheter free status in neurogenic bladder dysfunction: a review of bladder management options in spinal cord injury (SCI).

STUDY DESIGN: Review. OBJECTIVES: To assess current available options for bladder management in SCI patients the post-acute phase. METHODS: Relevant articles were extracted from medline and Cinahl between 1966--1999. In addition, references earlier than 1966 that were listed in these articles were identified and extracted. RESULTS: Catheterisation (indwelling or self intermittent) is still carried out by the majority of SCI patients with more morbidity for indwelling catheterisation. Other methods include condom drainage, suprapubic tapping and supreapubic pressure are used and are associated with less complications. Complicated procedures like sacral anterior root stimulator and entero-cystoplasty are carried out with the onset of or impending complications. CONCLUSION: Several methods of bladder management are available in the post-acute phase of SCI. The method used has to be based on urodynamic characteristics with the aim of producing a continent bladder with adequate low pressure storage capacity. Modern management of the bladder in SCI has successfully reduced renal related mortality in SCI from 95% in the first half of the 20th century to the present 3%.

The ice-water test in the diagnosis and treatment of the neurogenic bladder.

OBJECTIVE: To determine the usefulness of the ice-water test (IWT) in the diagnosis and treatment of neurological bladder disease. PATIENTS AND METHODS: The IWT was carried out in 148 patients with neuropathic bladder dysfunction resulting from a traumatic lesion, to assist in their diagnosis and treatment, and in 130 patients with neuropathic bladder dysfunction and multiple pathogenic disorders; the results of the IWT were used to classify those patients with hyperactive bladders. RESULTS: The IWT was positive in 95% of patients affected by complete and in 86% of patients with incomplete medullary lesions. The IWT in patients with lower motor neuron medullary lesions was always negative. The test was used diagnostically in all patients with lower and in 43% of those with upper motor neuron lesions. In the latter, it was used in 48% of patients as a rehabilitation method during the medullary-shock phase to accelerate the appearance of the micturition reflex. In 9% of patients it was used to induce micturition during cystography. CONCLUSION: Because it is simple to perform, the IWT is a useful complement to urodynamic examinations in patients with neurological bladder disease and in patients with micturitional disorders that are otherwise difficult to interpret.

The influence of colonic enema irrigation on urodynamic findings in patients with neurogenic bladder dysfunction.

OBJECTIVE: To evaluate whether colonic enema irrigation influences the urodynamic characteristics of patients with spina bifida, an overactive bladder and detrusor sphincter dyssynergia (DSD). PATIENTS AND METHODS: Since 1991, 83 patients with spina bifida at our institution have treated their bowel dysfunction by colonic irrigation every 24-48 h. In 12 patients (seven boys and five girls, mean age 7.7 years, range 0.7-13.8) with an overactive bladder and DSD, urodynamic studies of the bladder before and after enema treatment were available with no intercurrent changes in urological therapy. RESULTS: There were no significant changes overall in bladder capacity, leak-point pressure, bladder compliance and bladder instability in the selected group of children. CONCLUSION: Although enema therapy for bowel treatment in patients with spina bifida gave good results for faecal incontinence, with good patient compliance, no favourable effect on bladder function should be expected in most patients with a high-risk urinary tract dysfunction. Further study is needed to determine factors in patients who will benefit urologically from enema treatment.

An animal model for the neuromodulation of neurogenic bladder dysfunction.

OBJECTIVE: To develop an animal model to examine the pathophysiology by which S3 sacral root electrostimulation alters the micturition reflex in patients with bladder hyper-reflexia. MATERIALS AND METHODS: Chronic sacral nerve root electrostimulation was applied to spinally transected rats; 21 animals were divided into four groups. The spinal cord was completely transected at the T10-11 level and stainless-steel electrodes implanted into the sacral foramen in 17 animals; these animals were subsequently divided into two groups (1 and 2). Six rats in group 1 underwent sacral root elctrostimulation for 2 h/day and five in group 2 for 6 h/day, for 21 days. The sham group (group 3, six rats) received no stimulation and four rats were used as healthy controls (group 4). Voiding frequency was recorded and each animal was evaluated cystometrically at the end of the stimulation period. The results were compared with the sham and control groups. RESULTS: Spinal cord transection resulted in bladder areflexia and complete urinary retention; 7-9 days after the injury, the bladder recovered its activity. Twenty-one days after transection all animals had evidence of uninhibited bladder contractions. The mean (SD) hourly frequency of urination was 0.66 (0.18) in healthy controls, 0.83 (0.21) in group 1, 0.87 (0.34) in group 2 and 1.1 (0.31) in group 3. There was a significant decrease in eh cystometric signs of bladder hyper-reflexia in groups 1 and 2 when compared with group 3. CONCLUSIONS: This work reports and initial study showing that chronic electrostimulation of sacral nerve roots can reduce the signs of bladder hyper-reflexia in the spinally injured rat. To our knowledge, this is the first report describing the rat as an animal model to determine the effects of chronic electrostimulation on the micturition reflex.

Magnetic resonance urography in patients with neurogenic bladder dysfunction and spinal dysraphism.

OBJECTIVE: To investigate the reliability of magnetic resonance urography (MRU) using heavily T2-weighted very fast spin-echo sequences in imaging the upper urinary tract in patients with spinal dysraphism and neuropathic bladder dysfunction. PATIENTS AND METHODS: Patients with neuropathic bladder dysfunction secondary to spinal dysraphism may have gross spinal deformity, which makes assessing the urinary tract extremely difficult by ultrasonography or intravenous urography. The study included 50 patients (median age 33 years, range 19-52) with a median (range) Cobb's angle of 60 (0-240) degrees. No contrast medium was given but all patients received 20 mg of intramuscular frusemide 20-30 min before MRU. RESULTS: Thirty-five patients had previous ultrasonography, during which only 42 kidneys and no ureters were visible. Of the 94 renal tracts, MRU visualized all kidneys and 86 (89%) ureters. There was good agreement amongst observers on assessing the kidneys and pelvicalyceal systems (kappa > or = 0.61) but only moderate agreement on evaluating the ureters (kappa < or = 0.61). There was disagreement on normality vs renal parenchymal scarring in 14 (15%) kidneys, about no dilatation vs dilatation of the pelvicalyceal system in 14 (15%) systems and about no dilatation vs dilatation of the ureter in 20 (22%) ureters. The overall quality of the MRU images was rated highly, with a mean (range) score of 4.6 (3-5). CONCLUSION: MRU provides a reliable noninvasive technique for imaging the upper tract in patients who were previously difficult to investigate.

[Minimally invasive, safe treatment of the neurogenic bladder with botulinum-A-toxin in children with myelomeningocele].

PURPOSE: The efficacy and durability of botulinum-A toxin in the treatment of detrusor hyperreflexia in myelomeningocele (MMC) children was evaluated prospectively. MATERIALS AND METHODS: A total of 15 children (10 male and 5 female, mean age 5.8 years), all on clean intermittent catheterisation (CIC) due to MMC, were "non responders" to orally and intravesically administered anticholinergic medication. Pretreatment assessment included a videourodynamic evaluation, incontinence scoring and a mercaptoacetyltriglycine-3 renal scan. We injected from 10 U/kg up to a maximum of 360 U botulinum-A toxin at 25-40 sites of the detrusor, sparing the trigone. Follow-up was 24 months. All children had a urodynamic reevaluation with assessment of bladder capacity and incontinence score at 3, 9 and 12 months. RESULTS: Mean bladder reflex volume increased from 72.00 +/- 28.12 ml to 298 +/- 32.45 ml (p < 0.001). The maximal detrusor pressure decreased from 78.76 +/- 23.14 cm H(2)O to 42.76 +/- 24.34 cm H(2)O (p < 0.001). Maximal bladder capacity increased from 136.34 +/- 45.71 ml to 297.02 +/- 87.17 ml (p < 0.001). Detrusor compliance increased from 18.29 +/- 27.19 ml/cm H(2)O to 51.17 +/- 38.17 ml/mmH(2)O (p < 0.001). While 10 patients became completely dry between CIC, the remaining 2 patients improved from score 3 to 1. Results at 9 months were similar to the ones at 3 months. The mean efficacy and durability of the toxin was 10.5 months after the first intravesical injection. CONCLUSIONS: Botulinum-A toxin is a safe alternative in the management of detrusor hyperreflexia in MMC children. Preliminary results are promising concerning urodynamic parameters and continence.
