Abstract
INTRODUCTION Patients with spinal cord injuries/disorders (SCI/D) often suffer from bladder dysfunction, commonly referred to as neurogenic bladder or neurogenic lower urinary tract dysfunction (NLUTD). Standard urologic evaluation and management help to minimize complications such as vesicoureteral reflux, urinary tract infection, and nephrolithiasis. However, we have further encountered patients with more complex issues, such as chronic kidney disease (CKD), end-stage renal disease (ESRD), bilateral nephrectomies, and urinary diversion/augmentation surgeries. Of particular interest, there is a lack of standardized guidance for bladder management in SCI/D patients with ESRD. These patients are at high risk for urological complications and would benefit from codified bladder management strategies. CASE PRESENTATION In this article, we present eleven unique cases of NLUTD with associated ESRD and discuss recommendations utilizing simple and commonly available clinical interventions. DISCUSSION The inherently small population size of SCI/D patients with NLUTD and ESRD makes detailing a large sample size case series difficult. Future studies must aim to include a larger sample size as able, however, to better determine standardized protocols for chronic bladder management in SCI/D patients with NLUTD and ESRD. Experiences from this small case series are offered for consideration.

The Efficacy and Safety of Intrasphincteric Botulinum Toxin-A Injections in Patients with Non-Spinal Cord Injury-Related Detrusor Sphincter Dyssynergia: A Retrospective Study. Biomedicines 2023; 11:3016. [PMID: 38002018 PMCID: PMC10669099 DOI: 10.3390/biomedicines11113016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 11/01/2023] [Accepted: 11/07/2023] [Indexed: 11/26/2023] Open
Abstract
Botulinum toxin-A (BoNT-A) injections into the external urethral sphincter are an established therapeutic procedure for reducing bladder outlet obstruction in patients with detrusor sphincter dyssynergia (DSD) due to spinal cord injury (SCI). Given the paucity of data on patients with DSD but without SCI, we aimed to assess the efficacy of intrasphincteric BoNT-A injections in this cohort. For this retrospective study, we screened all patients who underwent their first intrasphincteric BoNT-A injection at our institution between 2015 and 2021. The inclusion criteria were patients aged 18 years or older with neurogenic detrusor overactivity (NDO) and DSD with a maximum detrusor pressure (Pdetmax) of >40 cmH2O, confirmed via video-urodynamic studies (VUDS). The primary outcome was a reduction in Pdetmax and detrusor overactivity leak point pressure (DOLPP) during NDO-associated urinary incontinence posttreatment. The secondary outcome was a reduction in patients relying on indwelling urinary catheters posttreatment. We included 13 eligible patients (all male, median age 31 years, with different underlying neurological disorders, except SCI). All underwent intrasphincteric BoNT-A injections with either 100 (n = 7) or 150 (n = 6) units, respectively. Pdetmax during voiding was significantly reduced posttreatment (median 105 vs. 54 cmH2O, p = 0.006), whereas DOLPP remained unchanged (i.e., median 50 cmH2O). While seven patients relied on indwelling urinary catheters pre-treatment, all were catheter-free posttreatment. Intrasphincteric BoNT-A injections in patients with non-SCI related DSD appear feasible for reducing bladder outlet obstruction to a certain degree in this cohort and subsequently for reducing the rate of indwelling catheters.

Abstract
Bladder dysfunction is a common complication after chronic spinal cord injury (SCI). Patients may experience renal function loss, urinary tract infection (UTI), urolithiasis, bladder cancer, and even life-threatening events such as severe sepsis or renal failure. Suitable patient care may prevent UTI and urinary incontinence, decrease medication use, and preserve renal function. As the primary goal is to preserve renal function, management should be focused on facilitating bladder drainage, the avoidance of UTI, and the maintenance of a low intravesical pressure for continence and complete bladder emptying. Currently, several bladder management options are available to SCI patients: (1) reflex voiding; (2) clean intermittent catheterization; (3) indwelling catheterization. The target organ may be the bladder or the bladder outlet. The purposes of intervention include the following: (1) increasing bladder capacity and/or decreasing intravesical pressure; (2) increasing bladder outlet resistance; (3) decreasing bladder outlet resistance; (4) producing detrusor contractility; (5) urinary diversion. Different bladder management methods and interventions may have different results depending on the patient's lower urinary tract dysfunction. This review aims to report the current management options for long-term bladder dysfunction in chronic SCI patients. Furthermore, we summarize the most suitable care plans for improving the clinical outcome of SCI patients.

Abstract
Introduction: Bladder and urinary sphincter malfunctioning that results from some change in the central and/or peripheral nervous system is defined as neurogenic bladder. The urinary tract symptoms that can be related to its filling, emptying, or both have a significant impact on the quality of life of individuals. The present review was based on the document prepared for the public health system in Brazil as a treatment guidelines proposal. Material and Methods: Survey questions were structured as per PICO (Population, Intervention, Control, and Outcome). Search strategies were defined and performed in the MEDLINE/Pubmed, Embase, Epistemonikos and Google Scholar databases. The selection of articles followed the evidence hierarchy concept; evidence body was identified, and the quantitative study data were extracted. The quality of evidence and grade of recommendation were qualitatively assessed according to GRADE (Grading of Recommendations, Assessment, Development and Evaluations). Results: A total of 2.707 articles were identified, with 49 of them being selected to compose the basis for this review. Neurogenic bladder treatments were classified according to their focus on filling or emptying symptoms and sub- classified in pharmacological and surgical treatments. Conclusion: Treatment guidelines are important tools for the public health system to promote the best practice when treating neurogenic bladder patients.

Abstract
BACKGROUND To evaluate in the short and mid-term the success of external sphincterotomy (ES) in neurological patients with detrusor sphincter dyssynergia (DSD). METHODS Retrospective, monocentric study, conducted in 51 patients who had a first ES between January 2003 and June 2018, with at least two years of follow-up. The success of ES was defined by maintenance of reflex voiding mode at the end of follow-up. Secondary outcomes were early postoperative complications, rate of revision, functional impact, urodynamic follow-up and upper urinary tract impact. RESULTS The median age was 50.6 years and the median follow-up was 4.6 years. The success rate was 80% (n=41). Ten patients had to change their voiding mode. For 5 patients, it was related to secondary detrusor low contractility. A second ES was required for 39% of patients. At the end of follow-up, there was a significant improvement in Autonomic Dysreflexia (AD) (26 vs 7 patients, P<0.001), urinary tract infections (UTI) (31 vs 15 patients, P<0.001) and a significant decrease in post-voiding residuals (200 vs 50mL, P<0.001). CONCLUSION ES allowed to maintain reflex voiding in 80% of our patients. It significantly improves AD and UTI despite a high rate of re-operation (39%). A long-term follow-up is mandatory in order not to ignore a recurrence of bladder outlet obstruction and/or decrease in detrusor contractility, which may justify a re-operation or an alternative bladder management.

Abstract
Impairments of the lower urinary tract function including urine storage and voiding are widely spread among patients with spinal cord injuries. The management of such patients includes bladder catheterization, surgical and pharmacological approaches, which reduce the morbidity from urinary tract-related complications. However, to date, there is no effective treatment of neurogenic bladder and restoration of urinary function. In the present study, we examined neuromodulation of detrusor (Detr) and external urethral sphincter by epidural electrical stimulation (EES) of lumbar and sacral regions of the spinal cord in chronic rats. To our knowledge, it is the first chronic study where detrusor and external urethral sphincter signals were recorded simultaneously to monitor their neuromodulation by site-specific spinal cord stimulation (SCS). The data obtained demonstrate that activation of detrusor muscle mainly occurs during the stimulation of the upper lumbar (L1) and lower lumbar (L5-L6) spinal segments whereas external urethral sphincter was activated predominantly by sacral stimulation. These findings can be used for the development of neurorehabilitation strategies based on spinal cord epidural stimulation for autonomic function recovery after severe spinal cord injury (SCI).

Abstract
BACKGROUND Patients with detrusor-sphincter dysynergia (DSD) who are unable to perform self-catheterisation can benefit from an endoscopic treatment. We chose regular urethral stent changes as an alternative to sphincterotomy in this kind of patients. The purpose of this study is to show that temporary urethral stents changes represent a treatment option with a reasonable morbidity for patients with DSD. METHODS We retrospectively reviewed patients in our center who had been treated with urethral stents from April 2005 to September 2017. The stent changes were performed every 12 to 18 months depending on urethrovesical fibroscopy findings. The primary endpoint was treatment continuation. RESULTS A total of 44 patients were enrolled in our study and the average follow-up duration was 46 months [18.5-53.25]. Primary treatment failure was seen in 14 (32%) patients mainly due to problems related to equipment (n=3) and urinary retention (n=2). Four patients died before their first stent change. The treatment was successful in 30 (68%) patients, of whom 10 (33%) subsequently adopted a voiding mode change. We lost sight of 5 patients (11%) during follow-up. The main complications were urinary retention (29%), urinary tract infections (27%) and stent migration (18%). Fifteen (34%) experienced grade III-IV complications. CONCLUSIONS Regular urethral stent changes represent an alternative treatment option for patients with DSD but with a significant morbidity. LEVEL OF EVIDENCE 4.

Abstract
AIMS To evaluate the impact of the pre-operative maximum detrusor pressure (MDP) on efficacy outcomes after incontinentation by sphincterotomy or urethral stent placement in male patients with neurogenic detrusor-sphincter dyssynergia (DSD). METHODS A retrospective study was performed in 41 male patients treated between 2006 and 2013 in a tertiary reference center. All patients had a neurogenic DSD confirmed by baseline urodynamic studies, and were unable or secondary failed to practice CISC. Success was defined as a post-void residual volume <150 mL. Influence of MDP on treatment efficacy was evaluated through a Mann-Whitney U-Test. RESULTS Median (range) age was 39 years (20-69). Spinal cord injury was the main underlying condition. Twenty-six patients had a sphincteric stent placement (Memocath®, Bard, Covington) and 15 had surgical sphincterotomy. Treatment was successful in 31 patients (76%). Patients with immediate successful outcomes had a significantly higher mean preoperative MDP (59.6 vs 29.7 cmH2 O; P = 0.002). Patients with MDP over the threshold of 40 cmH2 O had a 90% success rate. These differences were maintained at 6 months, MDP being higher in the success group than in the failure group (59.5 vs 39.8 cmH2 O, respectively, P = 0.008). The technique used (stent placement or incision) had no impact on immediate or 6-month success rates. CONCLUSIONS Our results suggested that MDP is associated with treatment success rate after surgical management of DSD of neurogenic origin by sphincteric stent placement or surgical sphincterotomy. A threshold of 40 mH2 O is associated with higher success rates.

Abstract
AIM The aim of this study was to assess the feasibility, efficacy and tolerance of Greenlight™ and Holmium sphincterotomy for treating detrusor-sphincter dyssynergia. METHODS All men treated with this two techniques between may 2012 and june 2015 were analyzed. Preoperative evaluation included kidney ultrasound scan, urodynamic, retrograde and voiding urethrocystography. Postoperative assessment was composed of a post-void residual volume measurement when the urethral catheter was removed and 1 year after the procedure, a retrograde and voiding urethrocystography at 3 months and telephonic Likert scale questionnaire. RESULTS Twelve patients were operated with Greenlight™ and 12 with Holmium. Eleven had a memocath urethral stent preoperatively. Post-void residual volume median for both techniques was 285 cc preoperatively vs 137.5 cc postoperatively (P<0.001). Likert scale global satisfaction was 75%. Five stenosis (20.8%) were observed within a median of 4 months. CONCLUSION Greenligth™ and Holmium procedures are efficient techniques with low morbidity. However, superiority toward monopolar incision remains to be demonstrated through complementary studies. LEVEL OF EVIDENCE 4.

Abstract
Detrusor-external sphincter dyssynergia (DSD) is a debilitating problem in patients with spinal cord injury. DSD carries a high risk of complications, and even life expectancy can be affected. Management of this condition includes the use of antimuscarinic agents in combination with intermittent catheterization, indwelling urethral catheterization, suprapubic catheterization, and a variety of surgical options, depending on patient and physician preference. This paper will review the current literature and data on minimally invasive and endoscopic management of DSD.

Abstract
Diverse lower urinary tract problems arise in neurologic disease, caused by dysfunctions of the bladder and outlet, both during urine storage and voiding. Most neurologic diseases cause some lower urinary tract dysfunction (LUTD), and the type of dysfunction is related to the location of the nervous system lesion. Clinical evaluation requires identification of risk factors for major morbidity, particularly renal dysfunction, and mechanisms underlying symptoms. A holistic approach is needed to cover influential aspects (e.g., cognitive function, mobility, and urinary tract infections) and related issues (e.g., sexual function, bowel function, and autonomic dysreflexia), requiring a multidisciplinary team. Comprehensive history and examination are supported by a bladder diary, urinalysis, and renal assessment, supplemented by urodynamic tests. The simplest classification of neurogenic LUTD describes both bladder and sphincter function, cataloging each structure as normal, overactive, or underactive. Treatment aims to protect life expectancy and improve quality of life, noting the possibility of neurologic disease progression and comorbid disorders. Conservative measures include fluid advice and assessment of suitable containment products. Urine storage can be improved with antimuscarinic medications, bladder injections with botulinum neurotoxin A, and less established methods such as nerve stimulation, intravesical instillations, and beta-3 agonist. For severe storage dysfunction, sacral neuromodulation or surgery to improve reservoir function, increase outlet resistance, or divert the urinary tract may be needed. Voiding is usually replaced by intermittent or indwelling catheterization, which has largely superseded triggered reflex voiding, bladder expression, or sphincterotomy. Treatment selection is hampered by a limited, low-quality evidence base.

Abstract
Bladder outlet obstruction (BOO) should be considered when a woman complains of voiding difficulty, abdominal straining to void, or refractory storage symptoms. Diagnosis of female BOO is not straightforward and usually requires invasive (video)urodyanmic study. A diagnostic algorithm is recommended for making optimal diagnosis. Female BOO can be classified as having anatomical and functional origins, and each contains several sub-classifications. Literatures published between 1988 and 2013 were reviewed and summarized for the diagnosis and therapy in each subtype of female BOO.

Abstract
OBJECTIVES To assess the impact of endo-urethral stent (EUP) of incontinentation in spinal cord injured (SCI) men on ejaculation capacity. FIRST CRITERIA Presence of ejaculation after EUP. SECONDARY CRITERIA Modification on ejaculation type, stimulation mode, possibility of sperm conservation in the same population. POPULATION AND METHODS A descriptive monocentric study including SCI subjects which underwent placement or change of temporary (Mémokath™ or Allium™) or definitive (Mémotherm™) EUP between January 2004 and January 2014 with at least one ejaculatory test. Are identified for each patient: the presence of ejaculation, type of ejaculation, stimulation mode used, number of frozen specimen and results from semen analysis. RESULTS Over 11 men with tetraplegia, complete for motricity, there were 8 (72%) for whom ejaculation was possible after laying EUP. Of these, 6 (55%) had an antegrade or antero-retrograde ejaculation. It was not possible to make a freezing straw in four of them due to infection of semen (2) or terato-oligo-astenospermia (1) or absence of reproductive project (1). CONCLUSION In this small sample, it was found that over 70% ejaculation have been preserved after laying EUP and more than 50% with antegrade or antero-retrograde ejaculation. A larger study would identify how EUP may alter the ejaculatory capacity or quality of the ejaculate. LEVEL OF EVIDENCE 4.

Abstract
Electrical stimulation for bladder control is an alternative to traditional methods of treating neurogenic lower urinary tract dysfunction (NLUTD) resulting from spinal cord injury (SCI). In this review, we systematically discuss the neurophysiology of bladder dysfunction following SCI and the applications of electrical stimulation for bladder control following SCI, spanning from historic clinical approaches to recent pre-clinical studies that offer promising new strategies that may improve the feasibility and success of electrical stimulation therapy in patients with SCI. Electrical stimulation provides a unique opportunity to control bladder function by exploiting neural control mechanisms. Our understanding of the applications and limitations of electrical stimulation for bladder control has improved due to many pre-clinical studies performed in animals and translational clinical studies. Techniques that have emerged as possible opportunities to control bladder function include pudendal nerve stimulation and novel methods of stimulation, such as high frequency nerve block. Further development of novel applications of electrical stimulation will drive progress towards effective therapy for SCI. The optimal solution for restoration of bladder control may encompass a combination of efficient, targeted electrical stimulation, possibly at multiple locations, and pharmacological treatment to enhance symptom control.

Abstract
In rats, axons of external urethral sphincter (EUS) motoneurons travel through the anastomotic branch of the pudendal nerve (ABPD) and anastomotic branch of the lumbosacral trunk (ABLT) and converge in the motor branch of the sacral plexus (MBSP). The aim of the present study was to determine in female rats the contribution of these somatomotor pathways and urethral sensory innervation from the dorsal nerve of the clitoris on urinary continence and voiding. EUS electromyographic (EMG) activity during cystometry, leak point pressure (LPP), and voiding efficiency (VE) were assessed in anesthetized virgin Sprague-Dawley female rats before and after transection of the above nerve branches. Transection of the MBSP eliminated EUS EMG, decreased LPP by 50%, and significantly reduced bladder contraction duration, peak pressure, intercontraction interval, and VE. Transection of the ABPD or ABLT decreased EUS EMG discharge and LPP by 25% but did not affect VE. Transection of the dorsal nerve of the clitoris did not affect LPP but reduced contraction duration, peak pressure, intercontraction interval, and VE. We conclude that somatomotor control of micturition is provided by the MBSP with axons travelling through the ABPD and ABLT. Partial somatomotor urethral denervation induces mild urinary incontinence, whereas partial afferent denervation induces voiding dysfunction. ABPD and ABLT pathways could represent a safeguard ensuring innervation to the EUS in case of upper nerve damage. Detailed knowledge of neuroanatomy and functional innervation of the urethra will enable more accurate animal models of neural development, disease, and dysfunction in the future.

Abstract
BACKGROUND The most common type of functional bladder outlet obstruction in patients with neurogenic bladder is detrusor-sphincter dyssynergia (DSD). The lack of co-ordination between the bladder and the external urethral sphincter muscle (EUS) in DSD can result in poor bladder emptying and high bladder pressures, which may eventually lead to progressive renal damage. OBJECTIVES To assess the effectiveness of different surgical therapies for the treatment of functional bladder outlet obstruction (i.e. DSD) in adults with neurogenic bladder dysfunction. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, and handsearching of journals and conference proceedings (searched 20 February 2014), and the reference lists of relevant articles. SELECTION CRITERIA Randomised controlled trials (RCTs) or quasi-RCTs comparing a surgical treatment of DSD in adults suffering from neurogenic bladder dysfunction, with no treatment, placebo, non-surgical treatment, or other surgical treatment, alone or in combination. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. MAIN RESULTS We included five trials (total of 199 participants, average age of 40 years). The neurological diseases causing DSD were traumatic spinal cord injury (SCI), multiple sclerosis (MS), or congenital malformations.One trial compared placement of sphincteric stent prosthesis with sphincterotomy. For urodynamic measurements, results for postvoid residual urine volume (PVR) and cystometric bladder capacity were inconclusive and consistent with benefit of either sphincteric stent prosthesis or sphincterotomy at three, six, 12, and 24 months. Results for maximum detrusor pressure (Pdet.max) were also inconclusive at three, six, and 12 months; however, after two years, the Pdet.max after sphincterotomy was lower than after stent placement (mean difference (MD) -30 cmH2O, 95% confidence interval (CI) 8.99 to 51.01).Four trials considered botulinum A toxin (BTX-A) injection in the EUS, either alone or in combination with other treatments. The comparators included oral baclofen, oral alpha blocker, lidocaine, and placebo. The BTX-A trials all differed in protocols, and therefore we did not undertake meta-analysis. A single 100 units transperineal BTX-A injection (Botox®) in patients with MS resulted in higher voided urine volumes (MD 69 mL, 95% CI 11.87 to 126.13), lower pre-micturition detrusor pressure (MD -10 cmH2O, 95% CI -17.62 to -2.38), and lower Pdet.max (MD -14 cmH2O, 95% CI -25.32 to -2.68) after 30 days, compared to placebo injection. Results for PVR using catheterisation, basal detrusor pressure, maximal bladder capacity, maximal urinary flow, bladder compliance at functional bladder capacity, maximal urethral pressure, and closure urethral pressure at 30 days were inconclusive and consistent with benefit of either BTX-A injection or placebo injections. In participants with SCI, treatment with 200 units of Chinese manufactured BTX-A injected at eight different sites resulted in better bladder compliance (MD 7.5 mL/cmH2O, 95% CI -10.74 to -4.26) than participants who received the same injections with the addition of oral baclofen. Results for maximum uroflow rate, maximal cystometric capacity, and volume per voiding were inconclusive and consistent with benefit of either BTX-A injection or BTX-A injection with the addition of oral baclofen. However, the poor quality of reporting in this trial caused us to question the relevance of bladder compliance as an adequate outcome measure.In participants with DSD due to traumatic SCI, MS, or congenital malformation, the results for PVRs after one day were inconclusive and consistent with benefit of either a single 100 units transperineal BTX-A (Botox®) injection or lidocaine injection. However, after seven and 30 days of BTX-A injection, PVRs were lower (MD -163 and -158 mL, 95% CI -308.65 to -17.35 and 95% CI -277.57 to -39.03, respectively) compared to participants who received lidocaine injections. Results at one month for Pdet.max on voiding, EUS activity in electromyography, and maximal urethral pressure were inconclusive and consistent with benefit of either BTX-A or lidocaine injections.Finally, one small trial consisting of five men with SCI compared weekly BTX-A injections with normal saline as placebo. The placebo had no effect on DSD in the two participants allocated to the placebo treatment. Their urodynamic parameters were unchanged from baseline values until subsequent injections with BTX-A once a week for three weeks. These subsequent injections resulted in similar responses to those of the three participants who were allocated to the BTX-A treatment. Unfortunately, the report presented no data on placebo treatment.Only the trial that compared sphincterotomy with stent placement reported outcome measures renal function and urologic complications related to DSD. Results for renal function at 12 and 24 months, and urologic complications related to DSD at three, six, 12, and 24 months were inconclusive and consistent with benefit of either sphincteric stent prosthesis or sphincterotomy.Adverse effects reported were haematuria due to the cystoscopic injection and muscle weakness, of which the latter may be related to the BTX-A dose used.All trials had some methodological shortcomings, so insufficient information was available to permit judgement of risk of bias. At least half of the trials had an unclear risk of selection bias and reporting bias. One trial had a high risk of attrition bias, and another trial had a high risk of reporting bias. AUTHORS' CONCLUSIONS Results from small studies with a high risk of bias have identified evidence of limited quality that intraurethral BTX-A injections improve some urodynamic measures after 30 days in the treatment of functional bladder outlet obstruction in adults with neurogenic bladder dysfunction. The necessity of reinjection of BTX-A is a significant drawback; a sphincterotomy might therefore be a more effective treatment option for lowering bladder pressure in the long-term.However, because of the limited availability of eligible trials, this review was unable to provide robust evidence in favour of any of the surgical treatment options. More RCTs are needed, measuring improvement on quality of life, and on other types of surgical treatment options for DSD since these are lacking. Future RCTs assessing the effectiveness of BTX-A injections also need to address the uncertainty about the optimal dose and mode of injection for this specific type of urological condition.

Abstract
AIMS Choosing the appropriate bladder management strategy for the spinal cord injury patient with neurogenic bladder and hand function prohibitive of self catheterization (urethral or stomal) catheterization is complex and based on limited literature. We have catalogued the available data in this review. METHODS A literature review was conducted on external sphincterotomy, suprapubic tube, ileal conduit, and ileovesicostomy between 1994 and 2012. Articles on neurogenic bladder focused primarily on spinal cord injury were included. Important aspects of each technique, patient selection, urologic events, and quality of life are described. CONCLUSION The available literature consists primarily of level 3 data. Patient reported outcomes were rarely measured. External sphincterotomy is a good option for males who are candidates for an external catheter and who wish to avoid a complicated reconstruction-most will need re-operations for failure. Suprapubic tube is an option in both genders. Complaints usually involve urine leakage and urinary tract infection, which typically resolve with conservative measures. There is some evidence to support patient satisfaction. Ileal conduit is an option for all patients with quadriplegia, offering continuous drainage and absence of foreign material. Many providers and patients will choose more conservative options first. The ileovesicostomy is best applied to small bladders with severe overactivity. The "reversibility" of this procedure makes it attractive to those not interested in an ileal conduit and who have had complications from prolonged suprapubic tube placement. The authors conclude with recommendations for future research, most importantly more standard reporting of objective data.

Abstract
BACKGROUND The effects of multiple injuries on the neurological and functional outcomes of patients with traumatic spinal cord injury (SCI) are debated-some groups have shown that subjects with multiple injuries have the same neurological and functional outcomes of those without them, whereas others have found that SCI patients with associated traumatic brain injury have worse functional status at admission and discharge and longer rehabilitation stays than patients without brain injury. Thus, the aim of this study was to compare the outcomes of SCI subjects with or without multiple injuries. METHODS A total of 245 patients with a traumatic SCI during the first rehabilitation stay after the development of the lesion (202 males and 43 females; age 39.8 ± 17 years; lesion to admission time 51.1 ± 58 days) were examined on a referral basis. Patients were assessed using the following measures: American Spinal Injury Association standards, Barthel Index, Rivermead Mobility Index, and Walking Index for Spinal Cord Injury. The statistical analysis comprised Poisson regression models with relative risks and 95% confidence intervals, adjusted for the following confounders: age, sex, lesion level, and ASIA impairment scale (AIS) grade. Student's T test was used to compare the outcomes of patients divided by AIS impairment and lesion level. RESULTS SCI patients with and without multiple injuries differed significantly with regard to the level and completeness of the lesion. Overall, patients with multiple injuries had worse functional status at admission and discharge than monotraumatic subjects. However, when adjusted for neurological features, the populations had comparable functional and neurological status at admission and discharge and similar rates of complications and discharge destinations. The separate analysis per each level of lesion/AIS grade showed that in some groups, patients with multiple injuries had a significant longer length of stay or worse functional status at rehabilitation admission (but not at discharge) than their monotraumatic counterparts. CONCLUSIONS Multiple injuries do not affect the neurological or rehabilitative prognosis of spinal cord injuries. At discharge, patients with spinal cord injuries with and without multiple injuries achieved similar results with regard to neurological and functional improvement. Some groups of patients with multiple injuries had a longer length of stay.

Abstract
This review examines the evidence for use of onabotulinumtoxinA in the treatment of neurogenic lower urinary tract dysfunction. Since its first use in 1988 to treat detrusor sphincter dyssynergia, use of botulinum toxin has increased in this group of patients. We discuss the mechanism of action, patient selection, dosing, efficacy, and side effect profile of this now licensed treatment option.

Abstract
Congenital anomalies such as meningomyelocele and diseases/damage of the central, peripheral, or autonomic nervous systems may produce neurogenic bladder dysfunction, which untreated can result in progressive renal damage, adverse physical effects including decubiti and urinary tract infections, and psychological and social sequelae related to urinary incontinence. A comprehensive bladder-retraining program that incorporates appropriate education, training, medication, and surgical interventions can mitigate the adverse consequences of neurogenic bladder dysfunction and improve both quantity and quality of life. The goals of bladder retraining for neurogenic bladder dysfunction are prevention of urinary incontinence, urinary tract infections, detrusor overdistension, and progressive upper urinary tract damage due to chronic, excessive detrusor pressures. Understanding the physiology and pathophysiology of micturition is essential to select appropriate pharmacologic and surgical interventions to achieve these goals. Future perspectives on potential pharmacological, surgical, and regenerative medicine options for treating neurogenic bladder dysfunction are also presented.

Abstract
PURPOSE To assess the clinical usefulness of Memokath® stent placement in the external sphincter region in men with neurogenic bladder dysfunction from spinal cord injury after failed sphincterotomy. PATIENTS AND METHODS Twenty-two men with elevated (> 100 mL) residual urine and/or voiding difficulties/autonomic dysreflexia were treated with a Memokath stent. Follow-up examinations comprised residual urine, video-urodynamics, renal sonography, and assessment of subjective outcome. RESULTS No intraoperative complications were observed. Transient autonomic dysreflexia developed in one patient. Stent repositioning from dislocation was necessary in four (18.2%) patients. After a median follow-up of 10.3 months, 18 (81.8%) patients still had a stent in place. In two men, the stents were removed because of newly diagnosed urothelial bladder cancer; in another two patients, they were removed because of lack of success. At follow-up, residual urine was significantly reduced from 229 to 105 mL. Residual urine was < 100 mL in 14 of 18 (77.8%) patients. Changes in bladder capacity, detrusor leak point pressure, bladder compliance, and maximum detrusor pressure were not statistically significant. Renal sonography did not reveal any pathologic findings. CONCLUSIONS According to our data, the Memokath stent is not only an alternative treatment option to sphincterotomy, but it is a safe and successful second-line treatment after sphincterotomy failure.

Abstract
CONTEXT Most patients with neurogenic lower urinary tract dysfunction (NLUTD) require life-long care to maintain their quality of life (QoL) and to maximise life expectancy. OBJECTIVE To provide a summary of the 2008 version of the European Association of Urology (EAU) guidelines on NLUTD and to assess the effectiveness of currently available diagnostic tools, particularly ultrasound imaging and urodynamics. EVIDENCE ACQUISITION The recommendations provided in the 2008 EAU guidelines on NLUTD are based on a review of the literature, using online searches of Medline and other source documents published between 2004 and 2007. A level of evidence and/or a grade of recommendation have been assigned to the guidelines where possible. EVIDENCE SYNTHESIS NLUTD encompasses a wide spectrum of pathologies, and patients often require life-long, intensive medical care to maximise their life-expectancy and to maintain their QoL. Treatment must be tailored to the needs of the individual patient and, in many cases, involves a multidisciplinary team of experts. Timely diagnosis and treatment are essential if irreversible deterioration of both the upper and lower urinary tracts are to be avoided. Therapeutic decisions are made on the basis of a comprehensive medical assessment, including urodynamics to identify the type of dysfunction. Advances in investigative technologies have facilitated the noninvasive and conservative management of patients who have NLUTD. CONCLUSIONS The diagnosis and treatment of NLUTD, which is a highly specialised and complex field involving both urology and medicine, requires up-to-date expert advice to be readily available. The current guidelines are designed to fulfil this need.

Abstract
BACKGROUND Detrusor-sphincter dyssynergia is a condition in which reflexive contractions of the external urethral sphincter occur during bladder contractions, preventing the expulsion of urine. High-frequency stimulation (kHz range) has been shown to elicit a fast-acting and reversible block of action potential propagation in peripheral nerves, which may be a useful technique in the management of this condition. OBJECTIVE The aim of these experiments was to see if a newly developed stimulus delivery system, capable of transmitting current transcutaneously to remote peripheral nerves using a passive implanted conductor, was an effective way to transmit high-frequency waveforms to the pudendal nerve to block ongoing sphincter contractions. METHODS High-frequency waveforms were delivered through the skin to the pudendal nerve using a passive implanted conductor in 6 adult cats anesthetized with isoflurane. Five of the experiments were acute, terminal procedures, and the remaining cat was implanted with a permanent electrode system allowing evaluation for 6 months. Typical stimulation parameters were in the range of 1 to 10 kHz and 1 to 10 mA. RESULTS Complete blocking of external urethral sphincter contractions was achieved in 5 of the 6 animals. High-frequency stimulation was also tested in the chronically implanted animal without anesthesia, and the stimulation was tolerated with minimal aversive reactions. CONCLUSIONS The transcutaneous passive implanted conductor stimulus delivery system is an effective way to stimulate the pudendal nerve at high frequency, leading to sphincter relaxation. This system may provide a simple means to implement this stimulation paradigm in people with detrusor-sphincter dyssynergia.

Abstract
OBJECTIVE To investigate the relationship between lesion severity and other clinical factors and bladder function recovery. PATIENTS AND METHODS The charts of 269 patients with traumatic and non traumatic spinal cord lesion (SCL) were reviewed and the following information was recorded: lesion to admission time, injury variables, length of stay and neurological status. At five months, urological outcome was assessed by voiding modalities, and urodynamics according to International Continence Society. Logistic approach with univariate and multivariate analysis. RESULTS Both ASIA impairment at admission and age were significantly correlated with bladder function outcome. None of the patients with ASIA A impairment at admission reached volitional voiding at five months. ASIA B patients had a 90% lower probability of achieving good bladder control and ASIA C ones a 65% lower than ASIA D patients (p < 0.05). Older patients had a significant lower probability (60%) of achieving volitional voiding than younger ones (p < 0.05). Of the 121 patients with ASIA D impairment at discharge only 78 voided spontaneously and showed a higher frequency of cervical lesions and a lower frequency of detrusor-external sphincter dyssynergia. DISCUSSION AND CONCLUSION Bladder recovery in patients with complete SCL is limited. ASIA B patients showed a better neurological recovery and, concurrently, better bladder function recovery than ASIA A patients, thus demonstrating the importance of sensation preservation for recovery. Younger patients show better bladder recovery than older ones, probably because of different efficiency of spinal cord plasticity. Finally, patients with good neurological recovery may not achieve volitional voiding. Patients with bladder function recovery show a higher frequency of central cord and Brown-Sequard syndromes (with better prognosis) and a lower frequency of detrusor-sphincter dyssynergia.

Abstract
Botulinum toxin type A (BTX-A) has been used to treat urethral and prostatic diseases (off-label uses). Injection of BTX-A into the external sphincter of patients with detrusor external sphincter dyssynergia has been shown to successfully lower postvoid residual volumes and detrusor pressures. Average efficacy is 3 to 4 months, but long-term effects on detrusor leak point pressures or renal function are unknown. Injection of BTX-A into the prostate has shown promising short-term results (< or = 12 months) in improving the symptoms, postvoid residual volumes, maximal urinary flow rates, and prostate sizes in patients with benign prostatic hyperplasia. The mechanisms of action and long-term durability of this treatment modality are unknown. Evidence supporting the use of BTX-A in treating detrusor hypocontractility, pelvic floor dysfunction, postpubovaginal sling retention, urethral stricture, prostatitis, and chronic pelvic pain syndrome in men is preliminary and deserves further evaluation.

Abstract
AIMS The vast majority of spinal cord lesions cause neurogenic bladder disorders. Detrusor hyperreflexia presents a major risk factor for renal damage in these patients. We evaluated the long-term results of patients with spinal cord injury treated at our institution. METHODS Eighty spinal cord injury patients (60 male, 20 female; mean age 29.6 years) with at least one follow-up visit a year for a minimum of five consecutive years, were included in this retrospective analysis. Follow-up included urodynamic evaluation, sonography of the upper and lower urinary tract, urine examination, and evaluation of renal function. Treatment modifications were based on the urodynamic findings. RESULTS Mean follow-up was 67.3 months (range 60-103 months). At initial presentation, 51 patients performed intermittent catheterization, 7 had indwelling catheters, 10 utilized reflex voiding, 2 patients presented with a Brindley stimulator, 10 patients used abdominal straining. At the end of our study, no patient had signs of renal damage. To achieve that goal, 8 patients underwent sphincterotomy, 3 received a Brindley stimulator, 3 underwent bladder augmentation, one Kock pouch was performed, and 12 patients were treated with botulinum-A-toxin injections in the detrusor. Twenty-two patients received intravesical anticholinergic therapy. In merely three patients, treatment was not modified during the entire follow-up. CONCLUSIONS In the long term, treatment strategy of neurogenic bladder dysfunction in patients with spinal cord injury had to be modified in almost all patients. 18.8% underwent surgery. For protection of the upper urinary tract and maintenance of continence, regular urodynamic follow-up is warranted.

Abstract
The treatment of neurogenic detrusor-sphincter dyssynergia is primarily medical (drugs and catheterization). Some patients may not be eligible for or fail to respond to these treatment options and endoscopic sphincterotomy or permanent prosthesis may be indicated. In this article, the authors review the indications, results and contraindications of these various treatments.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVES To assess in the long-term clinical and urodynamic results of intraurethral stents in a group of patients with spinal cord injury. SETTING Spinal Cord Injury Unit, Juan Canalejo Hospital, A Coruña, Spain. METHODS Forty-seven consecutive male patients were studied from 1993 to 2002. All of them suffered from hyperreflexia with detrusor-sphincter dyssynergia (DSD) owing to spinal cord injury, and were treated by means of the placement of an intraurethral stent at the external sphincter. RESULTS After surgery, significant decreases in all the parameters studied were observed. The number of patients with symptoms of urinary tract infection decreased by 25% (P<0.031). Post-void residual urine volume experienced an average decrease of 224.3 cm(3) (P=0.001). Episodes of dysreflexia decreased from 35.1 to 16.2% (P=0.039). The urodynamic study showed an average reduction of 44.36 cm H(2)O in the maximum detrusor pressure (P<0.0001). Complications in the upper urinary tract descended from 46.8 to 23.4% after placing the stent (P=0.013). The most frequent stent complication was displacement, followed by stenosis, lithiasis and intraprosthetic calcification. In all, 8.5% required the stent removal. CONCLUSIONS Intraurethral stent is a good choice for the long-term management of DSD in spinal cord-injured patients, even in those who had been previously submitted to prior sphincterotomy. It has the advantage of being a potentially reversible procedure, so patients prefer it to more invasive therapies such as sphincterotomy.

Abstract
The urological rehabilitation of spinal cord injury patients depends on an optimal urological treatment plan and good cooperation between the patient, general practitioner, urologist, and a centre that specialises in treating spinal cord injuries. Because of medical advancements in neuro-urology, one can assume that in cases of lifelong urological care, the individual's life expectancy will be almost normal. The recognition that nonphysiological bladder storage pressure results in restricted kidney function has led to various therapeutic strategies with complementary goals, such as protection of the upper urinary tract, urinary continence, individualized bladder management.

Abstract
Neurological control of micturition is undertaken by central and peripheral nerve systems through complex neuronal interconnections that are mediated by the action of several neurotransmitters, finally controlling the function of detrusor muscle and external urethral sphincter. In normal circumstances, both muscles must have co-ordinated contractions in such a way that when the detrusor contracts, the external urethral sphincter relaxes. The loss of this co-ordinated action leads to the so-called syndrome of detrusor-sphincter dyssynergia. Without adequate treatment, more than 50% of men with this condition will develop severe complications. There are several neurological diseases that might lead to this condition where a common physiopathology consists of a distortion of the complex neural mechanism innervating the lower urinary tract. Because of this complexity, it is difficult to find a curative treatment providing a definitive solution for a majority of patients. Although most of the currently available therapies only provide partial or temporary solutions, some modalities offer a promising perspective.

Abstract
Detrusor-external sphincter dyssynergia (DSD) is a debilitating problem in patients with spinal cord injury. DSD carries a high risk of complications, and even life expectancy can be affected. The mainstay of treatment is the use of antimuscarinic medication and catheterization, but in those for whom this is not possible external sphincterotomy has been the traditional management route. External sphincterotomy, however, is associated with significant risks, including hemorrhage, erectile dysfunction and the need for repeat procedures, and over the last decade alternatives have been investigated, such as urethral stents and botulinum toxin injection. We present a review of DSD, including the current management strategies and prospects for future treatment.

Abstract
A reversible electrical block of the pudendal nerves may provide a valuable method for restoration of urinary voiding in individuals with bladder-sphincter dyssynergia. This study quantified the stimulus parameters and effectiveness of high frequency (HFAC) sinusoidal waveforms on the pudendal nerves to produce block of the external urethral sphincter (EUS). A proximal electrode on the pudendal nerve after its exit from the sciatic notch was used to apply low frequency stimuli to evoke EUS contractions. HFAC at frequencies from 1 to 30 kHz with amplitudes from 1 to 10 V were applied through a conforming tripolar nerve cuff electrode implanted distally. Sphincter responses were recorded with a catheter mounted micro-transducer. A fast onset and reversible motor block was obtained over this range of frequencies. The HFAC block showed three phases: a high onset response, often a period of repetitive firing and usually a steady state of complete or partial block. A complete EUS block was obtained in all animals. The block thresholds showed a linear relationship with frequency. HFAC pudendal nerve stimulation effectively produced a quickly reversible block of evoked urethral sphincter contractions. The HFAC pudendal block could be a valuable tool in the rehabilitation of bladder-sphincter dyssynergia.

Abstract
PURPOSE Penile prosthetics are a viable option for erectile dysfunction in neurologically impaired patients. Penile implants can also be used to facilitate the management of urinary drainage when penile retraction has made this difficult. MATERIALS AND METHODS Between 1980 and 1996, 245 neurologically impaired patients with a mean age of 40.8 years (range 16 to 75), including 188 with paraplegia, 57 with quadriplegia and 197 with spinal cord injuries, were treated for erectile dysfunction and/or urinary incontinence with penile prosthesis implantation. The mean history of paralysis was 11.2 years (range 1 to 52). After neuro-urological evaluation all patients included in this study were considered candidates for penile prosthesis implantation. A followup program for treatment success, patient satisfaction, problems and complications was subsequently initiated. RESULTS During 17 years a total of 293 surgical procedures in 245 patients were done with the implantation of 147 semirigid (Jonas), 113 self-contained inflatable (Dynaflex) and 33 inflatable 3-piece (AMS 700) prostheses. There were 3 patient groups based on the indication for penile prosthetic surgery, namely group 1-134 patients with urinary management only, group 2-60 with erectile dysfunction only, and group 3-51 with urinary management and erectile dysfunction. At a mean followup of 7.2 years (maximum 17) 195 patients were reevaluated in clinic. In 122 patients (90.3%) urinary management problems were resolved. Erectile dysfunction treatment was successful in 76 patients (82.6%). There were 43 revisions for technical reasons and infections. The infection rate was 5% (12 patients). The perforation rate was different for different implant devices, that is 18.1% (15 of 83 cases) for semirigid devices, 2.4% (2 of 84) for self-contained inflatable devices and 0% (0 of 28) for inflatable 3-piece devices. CONCLUSIONS The implantation of a penile prosthesis is a safe procedure for erectile dysfunction and/or urinary incontinence in neurologically impaired patients. Based on technical advances the complication rates significantly decreased during the years. The implantation of an inflatable 3-piece penile prosthesis in a neurologically impaired patient is a safe and viable procedure. Indications include the management of erectile dysfunction and problematic urinary collection.

Abstract
There is no part of urology that has made so much progress in the last 25 years as neurourology. Seminal developments have been made in the selective effectiveness of drugs influencing neurogenic bladder dysfunction but having limited side effects. Additional advances are also likely to be made in the methods of functional electrostimulation and tissue engineering. Neurourology is predominantly influenced by our dynamic-functional understanding and the functionally oriented planning and implementation of treatment. The initial treatment options in many areas of neurourology are conservative, but, when possible, not irreversible. If these are ineffective or lead to late complications (e.g. by congenital paraplegia), there are a series of organ sparing or organ manipulating operations which can restore organ function. These make it possible to save kidney function from continuing damage, and, in many cases, to restore continence. The permanent indwelling catheter should remain excluded from the treatment of neurogenic bladder dysfunction. With adequate treatment, patients with neurogenic bladder dysfunction can be protected from severe complications and reintegrated into their normal social environment. After the acute phase of rehabilitation, urology is the most commonly required specialist area for paraplegic patients. In the past, urological problems have contributed most to the short lifespan of patients with an accident related spinal cord injury. Using modern neurourological treatment strategies, not only is lifespan increased but the quality of life of the patient is permanently improved.

Abstract
The management of urinary tract dysfunction is crucial for the health and well-being of people with spinal cord injury. Devices, specifically catheters, play an important role in the daily regime of bladder management for most people with spinal cord injury. However, the high incidence of complications associated with the use of catheters, and the fact that the spinal segments involved in lower urinary tract control remain intact in most cord-injured people, continue to motivate research into devices that could harness the nervous system to provide greater control over lower urinary tract function. Mechanical devices discussed in this review include catheters, artificial urethral sphincters, urethral stents and intraurethral pumps. Additionally, many attempts to restore control of the lower urinary tract with electrical stimulation have been made. Stimulation sites have included: inside the bladder, bladder wall, thigh, pelvic floor, dorsal penile nerve, pelvic nerve, tibial nerve, sacral roots, sacral nerves and spinal cord. Catheters and sacral root stimulators are two techniques whose efficacy is well established. Some approaches have proven less successful and others are still in the development stage. Modifications to sacral root stimulation including posterior root stimulation, anodal blockade and high-frequency blockade as well as new techniques including intraspinal microstimulation, urethral afferent stimulation and injectable microstimulators are also discussed. No single device has yet restored the control and function of the lower urinary tract to the pre-injury state, but new techniques are bringing this possibility closer to reality.

Abstract
Micturition is coordinated at the level of the spinal cord and the brainstem. Spinal cord injury therefore directly interrupts spinal neuronal pathways to the brainstem and results in bladder areflexia. Some time after injury, however, dyssynergic bladder and sphincter function emerges. The changes mediating the appearance of bladder function after spinal cord injury are currently unknown. Primary afferent neurons have been shown to sprout in response to spinal cord injury. Sprouting primary afferents have been linked to the pathophysiology of centrally manifested disorders, such as autonomic dysreflexia and neuropathic pain. It is proposed that sprouting of bladder primary afferents contributes to disordered bladder functioning after spinal cord injury. During development of the central nervous system, the levels of specific neuronal growth-promoting and guidance molecules are high. After spinal cord injury, some of these molecules are upregulated in the bladder and spinal cord, suggesting that axonal outgrowth is occurring. Sprouting in lumbosacral spinal cord is likely not restricted to neurons involved in the micturition reflex. Furthermore, sprouting of some afferents may be contributing to bladder function after injury, whereas sprouting of others might be hindering emergence of function. Thus selective manipulation of sprouting targeting afferents that are contributing to emergence of bladder function after injury is critical. Further research regarding the role that neuronal sprouting plays in the emergence of bladder function may contribute to improved treatment of bladder dyssynergia after spinal cord injury.

Abstract
STUDY DESIGN Case report. OBJECTIVES To report insidious development of autonomic dysreflexia and hydronephrosis due to dyssynergic voiding following discontinuation of intrathecal baclofen therapy. SETTING Regional Spinal Injuries Centre, Southport, UK. METHODS A male patient with paraplegia at T-5 (ASIA-A) had implantation of Medtronic Synchromed 8615 s programmable pump to control intractable spasms. After 4 years, the baclofen pump needed replacement because of battery exhaustion. At this time, he was taking oxybutynin 2.5 mg twice a day. He wore a penile sheath and performed intermittent catheterisation three times a day. Intravenous urography showed no dilatation of pelvicalyceal systems or ureters. During the course of the next 4 months, the dose of baclofen had to be increased gradually to 820 microg/day in order to control the spasms. Investigations revealed disconnection of the tube from the pump. The patient decided to undergo explantation of the pump and discontinue intrathecal baclofen therapy altogether. Following removal of the pump, he was prescribed baclofen 20 mg four times a day and diazepam 5 mg twice a day. He continued penile sheath drainage with oxybutynin 2.5 mg twice a day. Although spasms were controlled with oral baclofen and diazepam, he started getting transient, mild headache during reflex voiding. After nearly 2 years, he developed unbearable and pounding headache while passing urine. RESULTS The dose of oxybutynin was increased to modified release formulation, 20 mg, once daily. He was prescribed modified release alfuzosin 10 mg once a day. Indwelling urethral catheter drainage was instituted. Intravenous urography showed dilation of left renal pelvis and calyces, and left ureter. After a fortnight, the dose of modified release oxybutynin was increased further to 25 mg once a day. After a month, he started performing self-catheterisation every 3 h and symptoms of autonomic dysreflexia subsided completely. A follow-up intravenous urography performed 6 months later, showed normal appearances of the left kidney. CONCLUSION Spinal cord injury patients, in whom intrathecal baclofen therapy is terminated, need close monitoring of their urological status. Medications, which are prescribed for neuropathic bladder, and the method of bladder drainage, may need suitable changes, as discontinuation of intrathecal baclofen therapy can result in reappearance of detrusor-sphincter dyssynergia in previously susceptible patients.

Abstract
AIMS This functional urodynamic study assessed the effect of the nitric oxide donor isosorbide dinitrate on the external urethral sphincter and hypothesised first that nitric oxide could lower the resting sphincter pressure, second that nitric oxide could influence the sphincter contractility during magnetic stimulation, and third that nitric oxide could induce a faster external urethral sphincter fatigue during continuous magnetic stimulation. METHODS Eight healthy males gave their written informed consent and were included. A 2-channel microtip pressure transducer catheter was inserted into the urethra measuring the bladder and the external urethral sphincter pressure. Magnetic stimulation of the sacral roots was performed to evoke reproducible contractions of the external urethral sphincter. The baseline protocol included six single pulse stimulations and three stimulations 10sec in duration each for two frequencies 5Hz and 50Hz with intensities at the motor threshold of the pelvic floor. Then the subjects received 10 mg of isosorbide nitrate sublingually and the protocol was repeated 5min, 20min, 40min and 60min after drug administration. RESULTS The sublingual administration of isosorbide dinitrate could significantly reduce the resting pressure of the external urethral sphincter for at least one hour. The maximal contractile strength measured as the maximal urethral pressure during single pulse and continuous magnetic stimulation of the sacral roots also decreased significantly. Nitric oxide did not induce a significantly faster fatigue of the external urethral sphincter during continuous magnetic stimulation of the sacral roots. CONCLUSIONS This study shows a functionally relevant effect of nitric oxide on the resting tone and the contractile behaviour of the human external urethral sphincter in vivo while the fatigue properties did not changed significantly. Nitric oxide donors could offer a new pharmacological approach to treat urinary retention due to overactive or non-relaxing external urethral sphincter.

Abstract
Autonomic reflexes controlling bladder storage (continence) and emptying (micturition) involve spinal and supraspinal nerve pathways, with complex mechanisms coordinating smooth muscle activity of the lower urinary tract with voluntary muscle activity of the external urethral sphincter (EUS). These reflexes can be severely disrupted by various diseases and by neurotrauma, particularly spinal cord injury (SCI). Functional electrical stimulation (FES) refers to a group of techniques that involve application of low levels of electrical current to artificially induce or modify nerve activation or muscle contraction, in order to restore function, improve health or rectify physiological dysfunction. Various types of FES have been developed specifically for improving bladder function and while successful for many urological patients, still require substantial refinement for use after spinal cord injury. Improved knowledge of the neural circuitry and physiology of human bladder reflexes, and the mechanisms by which various types of FES alter spinal outflow, is urgently required. Following spinal cord injury, physical and chemical changes occur within peripheral, spinal and supraspinal components of bladder reflex circuitry. Better understanding of this plasticity may determine the most suitable methods of FES at particular times after injury, or may lead to new FES approaches that exploit this remodeling or perhaps even influence the plasticity. Advances in studies of the neuroanatomy, neurophysiology and plasticity of lumbosacral nerve circuits will provide many further opportunities to improve FES approaches, and will provide "artificial autonomic reflexes" that much more closely resemble the original, healthy neuronal regulatory mechanisms.
