Outcomes and efficacy of magnetic resonance imaging-compatible sacral nerve stimulator for management of fecal incontinence: A multi-institutional study. World J Radiol 2024; 16:32-39. [PMID: 38455883 PMCID: PMC10915907 DOI: 10.4329/wjr.v16.i2.32] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 11/24/2023] [Accepted: 02/02/2024] [Indexed: 02/23/2024] Open
Abstract
BACKGROUND Fecal incontinence (FI) is an involuntary passage of fecal matter which can have a significant impact on a patient's quality of life. Many modalities of treatment exist for FI. Sacral nerve stimulation is a well-established treatment for FI. Given the increased need of magnetic resonance imaging (MRI) for diagnostics, the InterStim which was previously used in sacral nerve stimulation was limited by MRI incompatibility. Medtronic MRI-compatible InterStim was approved by the United States Food and Drug Administration in August 2020 and has been widely used. AIM To evaluate the efficacy, outcomes and complications of the MRI-compatible InterStim. METHODS Data of patients who underwent MRI-compatible Medtronic InterStim placement at UPMC Williamsport, University of Minnesota, Advocate Lutheran General Hospital, and University of Wisconsin-Madison was pooled and analyzed. Patient demographics, clinical features, surgical techniques, complications, and outcomes were analyzed. Strengthening the Reporting of Observational studies in Epidemiology(STROBE) cross-sectional reporting guidelines were used. RESULTS Seventy-three patients had the InterStim implanted. The mean age was 63.29 ± 12.2 years. Fifty-seven (78.1%) patients were females and forty-two (57.5%) patients had diabetes. In addition to incontinence, overlapping symptoms included diarrhea (23.3%), fecal urgency (58.9%), and urinary incontinence (28.8%). Fifteen (20.5%) patients underwent Peripheral Nerve Evaluation before proceeding to definite implant placement. Thirty-two (43.8%) patients underwent rechargeable InterStim placement. Three (4.1%) patients needed removal of the implant. Migration of the external lead connection was observed in 7 (9.6%) patients after the stage I procedure. The explanation for one patient was due to infection. Seven (9.6%) patients had other complications like nerve pain, hematoma, infection, lead fracture, and bleeding. The mean follow-up was 6.62 ± 3.5 mo. Sixty-eight (93.2%) patients reported significant improvement of symptoms on follow-up evaluation. CONCLUSION This study shows promising results with significant symptom improvement, good efficacy and good patient outcomes with low complication rates while using MRI compatible InterStim for FI. Further long-term follow-up and future studies with a larger patient population is recommended.

Abstract
BACKGROUND The treatment of neurogenic bladder (NB) is a challenge because conventional therapy often fails. Sacral neuromodulation (SNM) is a minimally invasive technique and an unconventional treatment for neurogenic bladder. Its research is still in the exploratory stage. The research on its effectiveness and safety is not clear. OBJECTIVE To assess the effectiveness and safety of sacral neuromodulation (SNM) for neurogenic bladder (NB). METHODS By searching the PubMed databases and Cochrane Library databases, combined with the method of literature tracing, the clinical researches and works on neurogenic bladder and sacral neuromodulation therapy were collected. Two reviewers independently selected and extracted data, (1) determine whether the study meets the inclusion criteria and exclude the literature that meets the exclusion criteria. (2) Researchers' screening results and data, if there are differences in the results, will be discussed to eliminate the differences. (3) Read the full text of the literature carefully to determine the final literature to be included. (4) The relevant data of 11 independent studies, a total of 291 patients, were systematically reviewed using review manager 5.3 software. RESULTS This research included 11 independent studies with a total of 291 patients. The improvements of main outcomes before and after SNM therapy were significant: incontinence episodes /24 h (WMD -2.52; 95%CI-3.14-1.90; p <0.001), frequency/24 h (WMD-5.96; 95%CI -6.27,-5.66; p <0.001), voiding volume (WMD 116.09 mL; 95%CI 86.68,145.51; p <0.001), cystometric capacity (WMD 129.84 mL; 95%CI 100.53, 159.15; p <0.001), post-void residual volume (WMD-198.00 mL; 95%CI-264.60, -131.40; p <0.001), clean intermittent self-catheterization/24 h (WMD-2.48; 95%CI -2.96, -2.00; p <0.001). CONCLUSION This systematic review indicated that the sacral neuromodulation treatment for neurogenic bladder was effective and safe.

Abstract
INTRODUCTION Electrical spinal cord neuromodulation has emerged as a leading intervention for restoring autonomic functions, such as blood pressure, lower urinary tract (LUT), bowel, and sexual functions, following spinal cord injury (SCI). While a few preliminary studies have shown the potential effect of non-invasive transcutaneous spinal cord stimulation (tSCS) on autonomic recovery following SCI, the optimal stimulation parameters, as well as real-time and long-term functional benefits of tSCS are understudied. This trial entitled "Non-invasive Neuromodulation to Treat Bladder, Bowel, and Sexual Dysfunction following Spinal Cord Injury" is a pilot trial to examine the feasibility, dosage effect and safety of tSCS on pelvic organ function for future large-scale randomized controlled trials. METHODS AND ANALYSIS Forty eligible participants with chronic cervical or upper thoracic motor-complete SCI will undergo stimulation mapping and assessment batteries to determine the real-time effect of tSCS on autonomic functions. Thereafter, participants will be randomly assigned to either moderate or intensive tSCS groups to test the dosage effect of long-term stimulation on autonomic parameters. Participants in each group will receive 60 minutes of tSCS per session either twice (moderate) or five (intensive) times per week, over a period of six weeks. Outcome measures include: (a) changes in bladder capacity through urodynamic studies during real-time and after long-term tSCS, and (b) resting anorectal pressure determined via anorectal manometry during real-time tSCS. We also measure assessments of sexual function, neurological impairments, and health-related quality of life using validated questionnaires and semi-structured interviews. ETHICS AND DISSEMINATION Ethical approval has been obtained (CREB H20-01163). All primary and secondary outcome data will be submitted to peer-reviewed journals and disseminated among the broader scientific community and stakeholders.

Systematic Literature Review and Meta-Analysis of Sacral Neuromodulation (SNM) in Patients with Neurogenic Lower Urinary Tract Dysfunction (nLUTD): Over 20 Years' Experience and Future Directions. Adv Ther 2021; 38:1987-2006. [PMID: 33713279 PMCID: PMC8004509 DOI: 10.1007/s12325-021-01650-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Accepted: 02/03/2021] [Indexed: 01/23/2023]
Abstract
INTRODUCTION Sacral neuromodulation (SNM) has been used in carefully selected patients with neurogenic lower urinary tract dysfunctions (nLUTD) for over two decades. METHODS The aim of the current work was to perform a systematic literature review and meta-analysis of studies reporting the safety and effectiveness of SNM in patients with nLUTD (neurogenic detrusor overactivity, non-obstructive urinary retention, or a combination of both). For this purpose a systematic literature research was conducted using Embase (OvidSP), MEDLINE (OvidSP), MEDLINE In-Process Citations & Daily Update (OvidSP), MEDLINE (OvidSP) e-Pub ahead of print, Cochrane Central Register of Controlled Trials (CENTRAL), NIH Clinicaltrials.gov, and WHO International Clinical Trials Registry Platform (ICTRP) between 1998 and March 2020, supplemented by a hand search. RESULTS Forty-seven studies were included in the systematic literature review. Twenty-one studies comprising a total of 887 patients were included in the meta-analysis of test SNM. The pooled success rate of SNM test stimulation was 66.2% (95% CI 56.9-74.4). Depending on neurogenic conditions test success rates varied greatly. Twenty-four studies with a total of 428 patients were included in the meta-analysis of permanent SNM. The success rate of pooled permanent SNM was 84.2% (95% CI 77.8-89.0). Among the identified studies, the most common adverse events (AEs) were loss of effectiveness, infection, pain at implant site, and lead migration with AE rates of 4.7%, 3.6%, 3.2%, and 3.2%, respectively. Limitations entail lower level of evidence (Oxford classification 3-4) of included studies, significant risk of bias, small sample sizes in some studies, the inclusion of retrospective case series, substantial between-study heterogeneity, heterogeneous patient populations, insufficient disease classification, and variations in terms of outcome parameters as well as techniques. Furthermore, long-term data are limited. CONCLUSION This meta-analysis supports not only the benefits of permanent SNM for various nLUTDs but also high overall success rates, similar to idiopathic patients. Current data of the analyzed studies showed that SNM is safe for these patients. However, more vigorous studies and/or registries are needed before definitive conclusions can be drawn.

Improvements in Bladder Function Following Activity-Based Recovery Training With Epidural Stimulation After Chronic Spinal Cord Injury. Front Syst Neurosci 2021; 14:614691. [PMID: 33469421 PMCID: PMC7813989 DOI: 10.3389/fnsys.2020.614691] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 12/03/2020] [Indexed: 12/27/2022] Open
Abstract
Spinal cord injury (SCI) results in profound neurologic impairment with widespread deficits in sensorimotor and autonomic systems. Voluntary and autonomic control of bladder function is disrupted resulting in possible detrusor overactivity, low compliance, and uncoordinated bladder and external urethral sphincter contractions impairing storage and/or voiding. Conservative treatments managing neurogenic bladder post-injury, such as oral pharmacotherapy and catheterization, are important components of urological surveillance and clinical care. However, as urinary complications continue to impact long-term morbidity in this population, additional therapeutic and rehabilitative approaches are needed that aim to improve function by targeting the recovery of underlying impairments. Several human and animal studies, including our previously published reports, have documented gains in bladder function due to activity-based recovery strategies, such as locomotor training. Furthermore, epidural stimulation of the spinal cord (scES) combined with intense activity-based recovery training has been shown to produce volitional lower extremity movement, standing, as well as improve the regulation of cardiovascular function. In our center, several participants anecdotally reported improvements in bladder function as a result of training with epidural stimulation configured for motor systems. Thus, in this study, the effects of activity-based recovery training in combination with scES were tested on bladder function, resulting in improvements in overall bladder storage parameters relative to a control cohort (no intervention). However, elevated blood pressure elicited during bladder distention, characteristic of autonomic dysreflexia, was not attenuated with training. We then examined, in a separate, large cross-sectional cohort, the interaction between detrusor pressure and blood pressure at maximum capacity, and found that the functional relationship between urinary bladder distention and blood pressure regulation is disrupted. Regardless of one’s bladder emptying method (indwelling suprapubic catheter vs. intermittent catheterization), autonomic instability can play a critical role in the ability to improve bladder storage, with SCI enhancing the vesico-vascular reflex. These results support the role of intersystem stimulation, integrating scES for both bladder and cardiovascular function to further improve bladder storage.

Abstract
Fecal incontinence (FI) is defined as uncontrolled passage of feces or gas for at least 1-month duration in an individual who previously had control. FI is a common and debilitating condition affecting many individuals. Continence depends on complex relationships between anal sphincters, rectal curvatures, rectoanal sensation, rectal compliance, stool consistency, and neurologic function. Factors, such as pregnancy, chronic diarrhea, diabetes mellitus, previous anorectal surgery, urinary incontinence, smoking, obesity, limited physical activity, white race, and neurologic disease, are known to be the risk factors for FI. Conservative/medical management including biofeedback are recognized as the first-line treatment of the FI. Those who are suitable for surgical intervention and who have failed conservative management, sacral nerve stimulation (SNS) has emerged as the treatment of choice in many patients. The surgical technique involves placement of a tined lead with four electrodes through the S3 sacral foramen. The lead is attached to a battery, which acts as a pulse generator, and is placed under the patient's skin in the lower lumbar region. The use of SNS in the treatment of FI has increased over the years and the beneficial effects of this treatment have been substantiated by multiple studies. This review describes SNS as a modality of treatment for FI and its position in the current medical diaspora in patients with FI.

Abstract
Sacral nerve stimulation (SNS) is well-known as a minimally invasive treatment. Originally, it was mainly used to treat urinary system diseases such as urge urinary incontinence. Gradually, it is used to treat digestive system diseases such as fecal incontinence and chronic constipation. SNS is a method in which electrical pulse signals are sent out through pulse generators to stimulate the sacral nerve directly or indirectly, thus modulating the nerve reflex of the bladder, urethra, anus, colon, and rectum and improving abnormal nerve regulation to achieve the therapeutic effect. The regulation of the sacral nerve is often carried out by inserting electrodes into the sacral spinal canal S2-4 (mostly S3), and the symptoms are improved by complex regulation of spinal reflex and supraspinal reflex. However, the exact mechanism is still unclear. Many studies have shown that SNS plays a key role in the treatment of many diseases of the urinary system and digestive system. This paper reviews the progress in the research of SNS.

Abstract
PURPOSE OF REVIEW To provide an overview of available electrical stimulation devices in neurogenic patients with lower urinary tract disease. RECENT FINDINGS It is advocated to do more studies in neurogenic patients as results seem promising and useful but most studies did not include neurogenic patients or neurogenic patients were not analyzed or reported separately. Most studies included a small heterogenous neurogenic group with multiple pathophysiologic origin focusing on effect of a treatment instead of results of a treatment in a specific neurogenic group. Neuromodulation or stimulation has the advantage that it acts on different organs, like bladder and bowel, so can treat neurogenic patients, who mostly suffer from multiple organ failure. SUMMARY Brindley procedure, sacral neuromodulation (SNM) and posterior tibial nerve stimulation (PTNS) are available for a while already. The Brindley procedure (including sacral anterior root stimulation in combination with a rhizotomy of posterior sacral roots) is developed for selected spinal cord injury patient with a complete spinal injury, and has shown results for many years in neurogenic patients. An alternative to the rhizotomy is not established yet. SNM and PTNS are other modalities that are used in nonneurogenic patients, but are not yet indicated and much studied in neurogenic patients.

Abstract
CONTEXT Nocturia is among the most common and bothersome lower urinary tract symptoms (LUTS), but there is no clear consensus on how to identify and manage this symptom in the neurological population. OBJECTIVE To systematically review the literature about nocturia in neurological patients. EVIDENCE ACQUISITION Studies were identified by electronic search of Cochrane and Medline databases. The studies were included if their participants had acquired neurological pathology among multiple sclerosis (MS), Parkinson's disease (PD), stroke, spinal cord injury (SCI), and reported data on the epidemiology, aetiology, diagnosis, or treatment of nocturia. An independent extraction of the articles was performed by two authors using predetermined datasets, including quality-of-study indicators. EVIDENCE SYNTHESIS A total of 132 studies were included; 46 evaluated the epidemiology of nocturia, 28 the possible aetiologies, 10 the diagnostic tools, and 60 the treatments. Nocturia prevalence ranged from 15% to 96% depending on the pathology and definition used. It was one of the most frequently reported LUTS in PD and stroke patients. Several validated questionnaires were found to screen for nocturia in this population. Causalities were numerous: LUT, renal, sleep, cardiovascular dysfunctions, etc. Treatments targeted these mechanisms, with an overall risk of bias assessed as high or serious. The highest level of evidence was seen in MS patients: pelvic floor muscle training, cannabinoids, and desmopressin were effective, but not melatonin. In stroke patients, transcutaneous sacral and transcutaneous tibial nerve stimulation (TTNS) improved nocturia; in PD patients, TTNS, solifenacin, and rotigotine did not. CONCLUSIONS Nocturia is highly prevalent in patients with neurological disorders. Causalities and treatments are not different from the general population, but are poorly studied in neurological patients. PATIENT SUMMARY In this report, we looked at the published studies about nocturia-the fact of waking to void during the hours of sleep-in patients with neurological diseases. We found that nocturia is very frequent in this population, that the causes are the same as in the general population but may be combined, and that treatments are also the same but have an overall weak level of evidence. We conclude that more research is needed on this topic.

Abstract
According to the International Continence Society standardization reports, underactive bladder (UAB) is a decrease in detrusor contraction and/or shortening of the contraction time, resulting in an incomplete and/or prolongation of the bladder emptying within the normal time frame. It has been indicated that idiopathic, neurogenic, myogenic, and iatrogenic factors play a role in the etiology. To make a diagnosis, it is absolutely necessary to perform a pressure-flow study. Treatment alternatives are generally based on the evacuation of the lower urinary tract, independent of the etiology. UAB treatments are listed under the headings of conservative methods and clean intermittent catheterization, pharmacotherapy (alpha-blockers, cholinesterase inhibitors, muscarinic agonists, prostaglandin E2, and acotiamide), surgical treatments (sacral nerve stimulation-electrical stimulation, injections into the external sphincter, surgeries to be performed for bladder outlet obstruction, reduction cystoplasty, and latissimus dorsi detrusor myoplasty), and stem cell and gene therapies. It is still controversial whether satisfactory success is achieved in the treatment of patients with UAB. Owing to the better understanding of the pathophysiology, future developments in the pharmaceutical industry, gene therapy, and biomedical applications are expected to close the gap in the treatment.

Abstract
OBJECTIVE This study aimed to evaluate the effect of continuous care intervention on the quality of life (QoL) of patients with neurogenic bladder. METHODS Eighty-two patients with neurogenic bladder dysfunction caused by spinal cord injury were included into the study. All of the patients had continuous care intervention (for 3 months), including clean intermittent self-catheterization, drinking guidance, and bladder training guidance. A health record was established for each patient before discharge and was used to record changes in the patients when followed up. Scores of QoL, which were based on the World Health Organization Quality of Life-BREF, occurrence of complications, and compliance of all patients were recorded. RESULTS After 3-month care intervention, there were significantly fewer complications than before the intervention. Patients' compliance and QoL were significantly higher after 3 months of care intervention than before the intervention. CONCLUSION Continuous care intervention can improve patients' compliance and reduce urinary complications.

Abstract
Objective: To systematically review available studies on the effectiveness and safety of sacral neuromodulation (SNM) in women with various pelvic floor disorders not responding to more conservative treatment, as SNM is indicated in such women. Methods: Data source: We did a systematic review through the PubMed and the Cochrane Library according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement from 1998 to 2018 in English using the keywords ‘Sacral Neuromodulation’ and ‘Sacral Nerve Stimulation’. Study selection: Randomised controlled trials and prospective studies were selected, with a minimum sample size of 20 patients and ≥6 months of follow-up. Results: We identified 19 articles. A ≥50% reduction in symptoms qualifies the patient for a permanent implant. Several advances have been introduced into SNM to decrease the invasiveness of the procedure, including a smaller implantable pulse generator battery (improved comfort) and better localisation of the lead wire (improved outcome). The literature reports success for overactive bladder (OAB) to range between 56% and 68% (up to 80%). We report a 5-year therapeutic success rate of 67%. In our previous studies, 38% of our patients with urge urinary incontinence achieved complete continence at 60-months follow-up, with a therapeutic response rate of 57%. Effectiveness in patients with urinary retention and faecal incontinence are about 70% and 85%, respectively. Effectiveness in interstitial cystitis/bladder pain syndrome appears to be lower compared with OAB. Conclusion: SNM is a safe and effective therapy for women with various pelvic floor disorders.

Neuromodulation 2018; 22:697-702. [PMID: 30506765 DOI: 10.1111/ner.12895] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2018] [Revised: 09/23/2018] [Accepted: 10/16/2018] [Indexed: 11/26/2022]
Abstract
OBJECTIVES Incomplete spinal cord injury (SCI) accounts for two-thirds of all SCIs in clinical practice. Preclinical research on the effect of sacral neuromodulation (SNM) on bladder function, however, has been focused only on animal models of complete SCI. We aimed to evaluate the effect of early SNM on bladder responses in a rat model of incomplete SCI. MATERIALS AND METHODS Altogether, 21 female Sprague-Dawley rats were equally assigned to control (CTR), SCI + sham stimulation (SHAM), and SCI + SNM (SNM) groups. In the SHAM and SNM groups, incomplete SCI was created by producing a moderate contusion with an NYU-MASCIS impactor at the T9-T10 level of the spine, with needle electrodes implanted bilaterally into the S2 or S3 sacral foramen. Only SNM group underwent electrical stimulation for 28 days, beginning on day 7 after SCI. Cystometry was performed 35 days after SCI. RESULTS Although the interval between voiding contractions was significantly longer in the SHAM group than the CTR group (25.5 ± 1.4 vs. 12.5 ± 1.7 min; p < 0.05), there were no significant differences between the SNM group (16.5 ± 1.5 min) and the CTR group. Maximum voiding contraction pressure did not differ among the groups. The SNM group had a significantly lower frequency (3.5 ± 0.5 vs. 14.6 ± 2.0; p < 0.05) and maximum pressure (11.4 ± 6.2 vs. 21.3 ± 1.8 cmH2 O; p < 0.05) of nonvoiding contractions than the SHAM group. CONCLUSIONS Our results provide experimental evidence that early SNM treatment may prevent or diminish bladder dysfunctions (e.g., detrusor overactivity, abnormal micturition reflex) in a clinical condition of incomplete SCI.

Abstract
OBJECTIVE Locomotor training (LT) as a therapeutic intervention following spinal cord injury (SCI) is an effective rehabilitation strategy for improving motor outcomes, but its impact on non-locomotor functions is unknown. Given recent results of our labs' pre-clinical animal SCI LT studies and existing overlap of lumbosacral spinal circuitries controlling pelvic-visceral and locomotor functions, we addressed whether LT can improve bladder, bowel and sexual function in humans at chronic SCI time-points (> two years post-injury). STUDY DESIGN Prospective cohort study; pilot trial with small sample size. METHODS Eight SCI research participants who were undergoing 80 daily one-hour sessions of LT on a treadmill using body-weight support, or one-hour of LT and stand training on alternate days, as part of another research study conducted at the Kentucky Spinal Cord Injury Research Center, University of Louisville, were enrolled in this pilot trial. Urodynamic assessments were performed and International Data Set questionnaire forms completed for bladder, bowel and sexual functions at pre-and post-training time points. Four usual care (non-trained; regular at-home routine) research participants were also enrolled in this study and had the same assessments collected twice, at least 3 months apart. RESULTS Filling cystometry documented significant increases in bladder capacity, voiding efficiency and detrusor contraction time as well as significant decreases in voiding pressure post-training relative to baseline. Questionnaires revealed a decrease in the frequency of nocturia and urinary incontinence for several research participants as well as a significant decrease in time required for defecation and a significant increase in sexual desire post-training. No significant differences were found for usual care research participants. CONCLUSIONS These results suggest that an appropriate level of sensory information provided to the spinal cord, generated through task-specific stepping and/or loading, can positively benefit the neural circuitries controlling urogenital and bowel functions.

Abstract
Sacral neuromodulation (SNM) offers promise in the therapy of many pelvic floor disorders. This innovative treatment has slowly gained popularity. A review of recent literature is presented in relation to its efficacy and complications in various pelvic floor conditions: overactive bladder and urge urinary incontinence, chronic urinary retention, painful bladder syndrome, pelvic pain and double incontinence. It is a minimally invasive, completely reversible safe procedure with good long-term outcomes. However, the treatment is costly, the revision rate is high and patients require life-long follow-up. SNM should always be considered in suitable patients before offering bladder augmentation procedures or urinary diversion or permanent catheterization for bladder dysfunction. SNM should also be considered in patients with double incontinence, after discussion in a urogynaecology/colorectal multidisciplinary team.

Abstract
Sacral and peripheral neuromodulation are minimally invasive surgical procedures that are third-line therapy options for the treatment of patients with idiopathic overactive bladder syndrome. There has been interest in their efficacy in the management of neurogenic lower urinary tract dysfunction (NLUTD). Contemporary data suggest promising outcomes for urinary and bowel symptoms in carefully selected patients with spinal cord injury and/or multiple sclerosis. This article reviews the current literature regarding urinary and bowel outcomes in patients with NLUTD and also discusses contemporary studies that suggest that treatment during particular stages of neurologic injury may prevent long-term urinary sequelae.

Abstract
Background To systematically evaluate the therapeutic effect of electrical stimulation (ES) on overactive bladder (OB). Method
We retrieved information by searching databases from PubMed, CBM-disc, The Cochrane Library, ScienceDirect (from Elsevier publishers) and Springer publishers up to March 2016. We looked for randomized controlled trials that studied ES in OB treatment with subject headings and keywords using literature searches and manual retrieval. References of included studies were reviewed. Literature was screened independently by two investigators according to inclusion and exclusion criteria. After extracting data and evaluating their quality, meta-analysis was undertaken with RevMan v5.2. Results Ten randomized controlled trials involving 719 patients were included. Meta-analysis results demonstrated ES to have better effects for improving bladder compliance, reducing residual urine, and decreasing the frequency of enuresis in OB patients compared with the control group. ES elicited significantly better effects for diminishing the maximum detrusor pressure in children than in controls, but there was no significant difference in the maximum detrusor pressure between adults and controls. The therapeutic effect of ES combined with other therapies for increasing the maximum bladder capacity was better compared with other therapies alone. No significant difference was noted between ES alone and other therapies alone. Conclusions Based on current evidence, ES has certain effects on OBs. Severe adverse reactions are not observed. ES is safe, efficacious, and worthy of clinical use.

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
OBJECTIVE Neurogenic bladder refers to morphofunctional alterations of the bladder-sphincter complex secondary to central or peripheral neurological lesions. Discal etiology can be suggested by clinical observation in patients complaining of classical lower back pain, but not excluded even without musculoskeletal pain. This review provides a brief overview of associations between neurogenic bladder and disc disease, analyzing neuroanatomy, pathophysiology, clinical and urodynamic findings. Therapy is reviewed focusing on etiological treatments. METHODS The literature search was performed on PubMed, Medline and Google scholar using the following keywords: 'neurogenic bladder', 'disc herniation', 'disc prolapse', 'disc protrusion', 'cauda equina syndrome', 'treatment', 'surgery', 'urodynamic', either alone or in combination using 'AND' or 'OR'. The reference lists of articles retrieved were examined to capture other potentially relevant articles. The search was restricted to articles published between 1970 and 2012. Seventy-nine papers were found, but only 42 were reviewed and summarized. FINDINGS The literature reviewed confirmed correlations between neurogenic bladder and disc disease. Approximately 40% of patients with lumbar disc disease have abnormal urodynamic testing, and an even larger proportion complain of voiding symptoms. The most common urodynamic finding is detrusor areflexia, but underactive or overactive detrusor can also be observed. Electromyography can show perineal floor muscle innervation abnormalities. Chronic nervous damage induces reduction of bladder sensitivity and detrusor atrophy. An overdistension of the bladder follows, with global and circumferential thinning of the bladder wall. Overactive detrusor is related to early nerve roots stretching causing an irritative state responsible for overstimulation and neurogenic overactivity. Detrusor hypertrophy is the anatomical deformation correlated. CONCLUSIONS Benefits for neurogenic bladder obtained through disc disease treatment should be studied in more detail, especially conservative therapies, not yet discussed in literature. Spine surgery effectiveness on voiding function should be valued in the light of the latest surgical techniques, considering the controversial results reported after laminectomy.

Abstract
OBJECTIVES To evaluate the efficacy and safety over a 10-year period of any urological operations required by female patients with spinal cord lesions (SCLs). METHODS Retrospective study of urological surgeries from our database performed on females with SCLs from 2001 to 2002. Surgery efficacy for neurogenic lower urinary tract dysfunctions (N-LUTDs) was evaluated by comparing 7-day voiding diaries pre- and post-surgeries, while individual investigations were done pre- and post-surgery to evaluate urological complications. Drawbacks were assessed. RESULTS Thirty-eight out of 69 patients underwent one or more urological procedures. Twenty-one out of 42 patients with suprasacral lesions underwent interventions for N-LUTD. The main surgical treatment was endoscopic detrusor infiltration of botulinum-A (Botox 300 UI or Dysport 750 UI) performed 107 times on 15 subjects using aseptic intermittent catheterizations for neurogenic overactive bladder. Mean efficacy duration was 9.2 months. Six females with infrasacral lesions underwent at least one intervention for N-LUTD. Two females in each group underwent tension-free vaginal tape for stress urinary incontinence (SUI), reducing episodes per week of SUI by >90% after 5 years. The most serious urological complication was active vesico-ureteral reflux (VUR) in three patients, treated endoscopically with submucosal injection of Macroplastique. No VUR recurrence was detected during a 6-year follow-up. All bladder stones (five cases) and renal calculi (five cases) were treated with endoscopic transurethrally electrohydraulic lithotripsy and extracorporeal shock-wave lithotripsy, respectively. Overall, no serious drawbacks were observed. CONCLUSIONS Mini-invasive surgeries were exclusively used to address urological issues in chronic SCL patients.

Abstract
Due to the increasing popularity of neuromodulation, the number of indications and patient groups to which this technique is offered is also increasing. We evaluated the currently available data concerning neuromodulation in geriatric patients, children and patients with spinal cord injury and potential alternatives regarding neural targets and implantation techniques.The evidence of the use of neuromodulation in these patient groups is low. In geriatric patients, the use of neuromodulation seems to be justified. The few existing results concerning neuromulation in children are positive; however, there are no data about long term effects of neuromodulation on the growing organism. In patients with spinal cord injury, neuromodulation by microsurgical nerve anastomosis does not seem to be successful. According to the preliminary data of a single study, neuromodulation in acute spinal cord injury may prevent development of a neurogenic bladder dysfunction. The laparoscopic implantation of electrodes for neuromodulation unfolds new technical opportunities; however, until today there is no proof of the efficacy of this technique. Pudendal neuromodulation appears to be a meaningful addition to the therapeutic armamentarium for selected indications.The existing studies demonstrate the future opportunities of neuromodulation also in geriatric patients, children and patientens with spinal cord injuries. However, especially in the latter two groups, further studies concerning effectiveness and long term consequences are mandatory prior to offering these techniques to patients in everyday practise.

Abstract
PURPOSE The efficacy of sacral neuromodulation for treating refractory idiopathic lower urinary tract dysfunction is now well established. Nevertheless, results of this technique in neurological patients are still controversial. The aim of this retrospective study was to assess the results of sacral neuromodulation in neurogenic bladder dysfunction. MATERIALS AND METHODS Between 1998 and 2008, a percutaneous nerve evaluation or a two-stage technique was performed in 62 patients (mean age 50.5 ± 14.8 years) with neurogenic lower urinary tract dysfunction. Before and during the temporary stimulation, each patient had a urodynamic evaluation and performed a bladder diary. The test was considered positive if the clinical and urodynamic improvement was over 50% and if the symptoms reappeared after turning the stimulation off. RESULTS Lower urinary tract dysfunction was detrusor overactivity in 34 cases and chronic urinary retention in 28 cases. A detrusor-sphincter dyssynergia (DSD) was associated in nine cases. Out of the 62 patients, 41 patients (66.1%) had more than 50% improvement on urodynamic evaluation and bladder diary and 37 were implanted. With a mean follow-up of 4.3 ± 3.7 years, results remained similar to the evaluation phase in 28 cases (75.7%), were partially altered in three cases (8.1%) and lost in six cases (16.2%). In these six cases, neuromodulation failed on average 12.0 ± 12.4 months after implantation. CONCLUSION Sacral neuromodulation seems to constitute a serious therapeutic option for patients with neurogenic lower urinary tract dysfunction. However, its results depend on the type of the underlying neurologic disease and in particular, whether it may progress or not.

Abstract
AIM The aim of this article was to determine the effect of sacral nerve stimulation (SNS) on the treatment of faecal incontinence, constipation, irritable bowel syndrome, mixed urinary and bowel disorders, spinal injury and neurodegenerative disease, pain syndromes, and sexual dysfunction. METHOD A Medline search was performed including the keywords and/or MeSH headings of 'sacral nerve stimulation', 'neuromodulation', 'artificial pacemaker', 'faecal incontinence', 'constipation' and 'anal pain'. Further studies were identified by cross-referencing from relevant articles and by appraisal of recent peer-reviewed conference abstracts and proceedings. RESULTS SNS has been used for the treatment of urinary, bowel and sexual dysfunction, as well as pain resulting from such disorders, and dysfunction arising from nerve injury and degenerative disease. There is a paucity of high quality evidence to support the use of SNS for the majority of novel indications at present. CONCLUSION Good quality prospective, cross-over studies are required to determine the true benefits of SNS. Further research into patient selection, operative technique and stimulation parameters for existing indications will ensure a place for SNS in the future treatment algorithm of functional pelvic floor disorders.

Abstract
OBJECTIVES To assess the concomitant clinical improvement in incomplete spinal cord injury patients (SCIPs) suffering from neurogenic bowel symptoms (NBSs), neurogenic lower urinary tract symptoms (NLUTSs) and neurogenic erectile dysfunction (NED) using sacral neuromodulation (SNM) for NBSs and NLUTSs. METHODS Seventy-five SCIPs were selected. Before and during the follow-ups post-SNM, NLUTSs and NBSs were detected mainly through specific diaries. Erectile function was assessed using the International Index of Erectile Function composed of 5 questions (IIEF5). Quality of life (QoL) was measured with the Short Form 36 Health Survey questionnaire (SF-36). During the first stage, in which a permanent electrode was inserted percutaneously into the third sacral foramina and stimulated using an external generator, patients with NBSs or NLUTSs were required to improve their symptoms by at least 50% compared with baseline before proceeding to the second stage in which the generator was placed in the patient's buttock. NED patients needed to increase their IIEF5 score by at least 25% compared with baseline (evaluated initially 3 months after the second stage) in order to continue follow-up. RESULTS Fourteen out of 37 subjects who manifested two functional pelvic dysfunctions at baseline maintained notable clinical improvement in two pelvic functions (median follow-up >3 years). Six had non-obstructive retention (NOR) and NED, six double incontinence, and two constipation with NOR. In the general and mental health domains of the SF-36, all patients improved their scores by at least 20% compared with baseline. CONCLUSIONS SNM may be beneficial to selected incomplete SCIP with concomitant pelvic functional disturbances.

Abstract
PURPOSE OF REVIEW In recent years, sacral neuromodulation (SNM) has been investigated for the treatment of various types of lower urinary tract and bowel dysfunctions. This review discusses recently published data related to the therapeutic applications of SNM in female lower urinary tract, pelvic floor, and bowel disorders. RECENT FINDINGS SNM has been employed initially in the treatment of refractory idiopathic overactive bladder, urge urinary incontinence, and chronic nonobstructive urinary retention. Since then, several studies, including randomized and controlled trials, have confirmed the therapeutic effects of SNM in these disorders. The applications of SNM are now extended to the treatment of other female pelvic problems, such as fecal incontinence, chronic constipation, interstitial cystitis/painful bladder syndrome, sexual dysfunction, and neurogenic disorders, with similar promising results. SUMMARY SNM is approved by the Food and Drug Administration for the treatment of idiopathic overactive bladder, urge urinary incontinence, and chronic nonobstructive urinary retention. SNM is not yet an approved method for the treatment of other pelvic disorders, but data supporting its benefit are emerging. The major advantage of SNM lies in its potential to treat the bladder, urethral sphincter, anal sphincters, and pelvic floor muscles simultaneously, which might result in better therapeutic effects.

Abstract
AIMS To report the conclusion of the Think Thank on Neurourology discussions during the first ICI-RS meeting in 2009. METHODS During a 3-day meeting a group of specialists discussed evidence-based medicine in neurourology and made suggestions for future research. RESULTS In the vast majority of patients with neurological disease bladder dysfunction occurs. The actual rules of diagnosis and treatment lack a study related evidence base. From a long list of possible research subjects, prevalence, detrusor pressure, imaging, catheterization and surgery have been first discussed. CONCLUSION In each of these subjects, research items are suggested which can help to improve the care in this patient group.

Abstract
Pharmacologic therapies, primarily antimuscarinic agents, have been the mainstay of treatment for overactive bladder. These drugs produce variable efficacy, a moderate rate of side effects, and rare occurrences of cure. The search for newer and better formulations and derivatives of this class of medication as well as novel therapies is ongoing and primarily fueled by the high prevalence of overactive bladder and the tremendous number of health care dollars spent on current therapy. Surgical options for overactive bladder have evolved slowly and are currently reserved for medical treatment failures and drug intolerance. This article will highlight the new drugs and therapies brought into clinical use for the treatment of overactive bladder over the last few years as well as a promising new agent in the advanced stages of development.
