[Sacral neuromodulation for bladder voiding dysfunction: Experience at a French university center]. / Neuromodulation sacrée pour trouble de la vidange vésicale : expérience d'un centre universitaire français.

OBJECTIVE: To report the experience of a university hospital center with sacral neuromodulation for patients with bladder voiding disorders. MATERIAL AND METHODS: All patients who underwent sacral neuromodulation between 1998 and 2022 for bladder voiding disorders were included. Medical records were analyzed retrospectively, and population, efficacy and follow-up data were collected. RESULTS: A total of 134 patients underwent test implantation and 122 patients were analyzed. 68 patients (56%) were implanted with a definitive neuromodulation device. Mean age was 43±16 years and BMI 25.5±5.4kg/m2. 74% were women. Bladder voiding disorder was due to sphincter hypertonia in 51% of cases, with associated bladder hypocontractility in 29%. The spontaneous micturition rate after implantation increased from 34% to 92%. Implantation results appeared to be better in patients with sphincter hypertonia, whether or not associated with bladder hypocontractility. The benefit was most often present with a frequency of 5Hz (54.4%). Side-effects were present in 52% of cases at 5 years, and in 85% of cases were pain in relation to the implanted devices. They resolved under medical treatment or after revision of the device (27% of cases at 5 years). CONCLUSION: SNM is effective in micturition recovery, but has side effects. Urodynamic mechanism and etiology may provide clues for modulating NMS box settings and determining predictive factors for NMS success. Data from other centers are needed to identify reliable predictive factors.

A new tool to investigate anorectal disorders in patients with multiple sclerosis: STAR-Q.

BACKGROUND: Bowel symptoms are commonly experienced by patients with Multiple sclerosis (PwMS), but no specific questionnaire validated in this population allows a rigorous assessment. OBJECTIVE: Validation of a multidimensional questionnaire assessing bowel disorders in PwMS. METHODS: A prospective, multicenter study was conducted between April 2020 and April 2021. The STAR-Q (Symptoms' assessmenT of AnoRectal dysfunction Questionnaire), was built in 3 steps. First, literature review and qualitative interviews were performed to create the first version, discussed with a panel of experts. Then, a pilot study assessed comprehension, acceptation and pertinence of items. Finally, the validation study was designed to measure content validity, internal consistency reliability (alpha coefficient of Cronbach) and test-retest reliability [intraclass correlation coefficient (ICC)]. The primary outcome was good psychometric properties with Cronbach's α>0.7 and ICC>0.7. RESULTS: We included 231 PwMS. Comprehension, acceptation and pertinence were good. STAR-Q showed a very good internal consistency reliability (Cronbach's α=0.84) and test-retest reliability (ICC=0.89). Final version of STAR-Q was composed of 3 domains corresponding in symptoms (Q1-Q14), treatment and constraints (Q15-Q18) and impact on quality of life (Q19). Three categories of severity were determined (STAR-Q≤16: minor, between 17 and 20: moderate, and≥21: severe). CONCLUSIONS: STAR-Q presents very good psychometric properties and allows a multidimensional assessment of bowel disorders in PwMS.

[Guidelines on the urological management of the adult patient with spinal dysraphism (spina bifida)]. / Recommandations sur la gestion du risque et la prise en charge urologique du patient adulte atteint de dysraphisme spinal (spina bifida).

INTRODUCTION: Improved life expectancy and prenatal screening have changed the demographics of spina bifida (spinal dysraphism) which has presently become a disease of adulthood. Urinary disorders affect almost all patients with spinal dysraphism and are still the leading cause of mortality in these patients. The aim of this work was to establish recommendations for urological management that take into account the specificities of the spina bifida population. MATERIALS AND METHODS: National Diagnosis and Management Guidelines (PNDS) were drafted within the framework of the French Rare Diseases Plan at the initiative of the Centre de Référence Maladies Rares Spina Bifida - Dysraphismes of Rennes University Hospital. It is a collaborative work involving experts from different specialties, mainly urologists and rehabilitation physicians. We conducted a systematic search of the literature in French and English in the various fields covered by these recommendations in the MEDLINE database. In accordance with the methodology recommended by the authorities (Guide_methodologique_pnds.pdf, 2006), proposed recommendations were drafted on the basis of this literature review and then submitted to a review group until a consensus was reached. RESULTS: Bladder dysfunctions induced by spinal dysraphism are multiple and varied and evolve over time. Management must be individually adapted and take into account all the patient's problems, and is therefore necessarily multi-disciplinary. Self-catheterisation is the appropriate micturition method for more than half of the patients and must sometimes be combined with treatments aimed at suppressing any neurogenic detrusor overactivity (NDO) or compliance alteration (anticholinergics, intra-detrusor botulinum toxin). Resort to surgery is sometimes necessary either after failure of non-invasive treatments (e.g. bladder augmentation in case of NDO resistant to pharmacological treatment), or as a first line treatment in the absence of other non-invasive alternatives (e.g. aponeurotic suburethral tape or artificial urinary sphincter for sphincter insufficiency; urinary diversion by ileal conduit if self-catheterisation is impossible). CONCLUSION: Spinal dysraphism is a complex pathology with multiple neurological, orthopedic, gastrointestinal and urological involvement. The management of bladder and bowel dysfunctions must continue throughout the life of these patients and must be integrated into a multidisciplinary context.

The combination of deep breathing and mental imagery promotes cardiovascular recovery in firefighters.

Firefighters' rescue operations involve intense physical activity associated with a high level of cardiovascular stress. To sustain such intense physical performance whilst maintaining a healthy heart, it is crucial that they benefit from rapid recovery between each intervention. This study aimed at investigating the impacts of a recovery protocol combining deep breathing and mental imagery. Forty firefighters were divided into two experimental groups which undertook two maximum fitness tests separated by either the control recovery protocol (30 min reading time; n = 20) or the experimental recovery protocol (30 min of deep breathing and mental imagery; n = 20). When compared to the pre-tests, the percentage evolution ratios in the post-tests for the Cooper performance, the heart rate recovery and the parasympathetic reactivation were promoted by the experimental protocol, compared to simple reading. In light of these results, we propose the use of practices of deep-breathing combined with mental imagery to improve firefighters' recovery. Practitioner summary: Firefighters' activities involve intense physical activities associated with a high level of psychological stress. Enhancing their recovery after each rescue intervention appears crucial. The results of this study showed that a recovery protocol combining deep breathing and mental imagery promotes heart rate recovery and better maintenance of physical fitness.

Prospective multicentre observational study assessing the tolerance and perception of patients using the Liquick Base catheter with an Ergothan tip.

INTRODUCTION: Intermittent self-catheterisation has revolutionised the management of neurogenic bladder-sphincter dysfunctions. The Liquick Base catheter is characterised by a streamlined Ergothan tip. The purpose of this study is to assess the tolerance and perception of patients using this catheter. MATERIALS AND METHODS: A French prospective multicentre observational study was conducted on patients with neurogenic bladder-sphincter dysfunctions. Upon inclusion in the study, the doctor completed a questionnaire on the patient's pathology. After 3 and 6 months, the doctor checked for neurogenic developments or observations and looked for any complications relating to intermittent self-catheterisation. The patient completed a questionnaire to assess his or her perception of using the catheter. RESULTS: Out of 42 patients included in the study, two were excluded. Out of the 40 assessed patients (30 males, 10 females) with an average age of 50.1±14.9 years, there were no reported cases of false passage. Bleeding occurred at least once in 10 patients (25%) in the first three months and in three out of 20 patients (15%) between 3 and 6 months. Two (5%) patients sought medical attention in the first three months for complications related to the catheter and 4 patients sought medical attention (10%) between 3 and 6 months. After 3 months 90% of patients were still using the catheter and after 6 months 90% of patients were still using the catheter. CONCLUSION: The Liquick Base catheter is well tolerated. Patient perception is positive for all parameters being examined, leading to the continued use of the catheter in 90% of cases. LEVEL OF EVIDENCE: 2.

Use of Malone antegrade continence enemas in neurologic bowel dysfunction.

INTRODUCTION: Patients with neurogenic bowel dysfunction (NBD) suffer severe constipation and/or fecal incontinence that are very difficult to treat. Most medication-based and interventional treatments have been unsuccessful. The goal of this study was to assess the medium-term effectiveness of the Malone procedure in all patients with NBD, as an alternative to colostomy. PATIENTS AND METHODS: In this retrospective single-center study, 23 patients who underwent Malone's surgical treatment were analyzed. The main criteria were the usage of antegrade colonic enemas (ACE) after Malone's procedure at the most recent follow-up and comparison of quality of life scores before and after surgery. RESULTS: The post-procedure mortality was zero, but an overall morbidity of 60% was observed, including minor complications (Clavien 1, 2) in 56%. The median follow-up was 33 months. At the most recent follow-up, the utilization rate of the neo-appendicostomy for ACE was 69.6%; 76.9% of the patients using ACE reported improvement in quality of life scores. Secondary colostomy was performed in 21.7% for functional failure of the Malone procedure. CONCLUSION: The Malone procedure is a reliable technique that can be used in the therapeutic strategy for managing NBD patients with incontinence/constipation refractory to usual treatments. It should be considered as a therapeutic step to take before resorting to colostomy.

Intermittent catheterization: Clinical practice guidelines from Association Française d'Urologie (AFU), Groupe de Neuro-urologie de Langue Française (GENULF), Société Française de Médecine Physique et de Réadaptation (SOFMER) and Société Interdisciplinaire Francophone d'UroDynamique et de Pelvi-Périnéologie (SIFUD-PP).

INTRODUCTION: Our objective was to provide guidelines covering all aspects of intermittent catheterisation (intermittent self-catheterisation and third-party intermittent catheterisation). MATERIALS AND METHODS: A systematic review of the literature based on Pubmed, Embase, Google scholar was initiated in December 2014 and updated in April 2019. Given the lack of robust data and the numerous unresolved controversial issues, guidelines were established based on the formal consensus of experts from steering, scoring and review panels. RESULTS: This allowed the formulation of 78 guidelines, extending from guidelines on indications for intermittent catheterisation, modalities for training and implementation, choice of equipment, management of bacteriuria and urinary tract infections, to the implementation of intermittent catheterisation in paediatric, geriatric populations, benign prostatic hyperplasia patients and continent urinary diversion patients with a cutaneous reservoir as well as other complications. These guidelines are pertinent to both intermittent self-catheterisation and third-party intermittent catheterisation. CONCLUSION: These are the first comprehensive guidelines specifically aimed at intermittent catheterisation and extend to all aspects of intermittent catheterisation. They assist in the clinical decision-making process, specifically in relation to indications and modalities of intermittent catheterisation options. These guidelines are intended for urologists, gynaecologists, geriatricians, paediatricians, neurologists, physical and rehabilitation physicians, general practitioners and other health professionals including nurses, carers….

Cerebral imaging of post-stroke plasticity and tissue repair.

Six months after stroke onset, 50 % of patients are still disabled and dependent, while many brain mechanisms of recovery remain partially unknown or misunderstood. However, brain imaging and cerebral connectivity analytical techniques have provided invaluable insights into such mechanisms and identified two main patterns of brain reorganization depending on stroke severity. The contralesional primary motor cortex can take over motor function in severely impaired patients, whereas the ipsilesional motor cortex or hemisphere reorganize themselves in good recoverers. These patterns evolve with time after stroke, and highlight ipsilesional and contralesional primary and secondary areas that appear to take over lost functions. The crucial role of these areas has been confirmed by histological tracer studies. In addition, non-invasive techniques can stimulate post-stroke brain plasticity, although appropriate targets first need to be found. Imaging has proved useful for finding such appropriate targets and has also provided biomarkers of efficacy with various therapies. Moreover, it has provided some clues to the mechanisms of action of recovery-enhancing drugs. These imaging techniques have also identified patients who show atypical reorganization and recovery patterns. Thus, it may be necessary to design individualized and targeted therapies.

Ejaculation and sperm characteristics in men with cauda equina and conus medullaris syndromes.

STUDY DESIGN: Retrospective. OBJECTIVES: The objective of the study was to describe the type of ejaculation in patients with cauda equina (CE) and conus medullaris (CM) lesions, and to analyse sperm quality. SETTING: France. METHODS: One hundred sixty-six patients with CE and CM lesions were included. Diagnosis was based on clinical (no motor responses, sensation or sacral reflexes) and urodynamic assessments (no detrusor activity). Vibromassage (VM) was used to induce ejaculation according to the recommendations for patients with spinal cord injury. If ejaculation did not occur, oral midodrine was administered in progressive doses. Retrograde ejaculation was systematically sought. Sperm parameters were analysed according to World Health Organisation recommendations (2010). RESULTS: Eighty-nine patients were included. Eleven ejaculated on the first VM trial (four anterograde (AE), six retrograde (RE) and one antero-retrograde (ARE)). Five patients continued trials of VM alone, two of whom ejaculated following a mean 1.9 trials (one RE, one ARE). Twenty-six patients underwent trials of VM+ midodrine, 18 of whom ejaculated following a mean 4.4 trials with a mean dose of 22.5 g of midodrine (2 AE, 13 RE and 5 ARE). Fifty-three ejaculates from 26 patients were analysed. Sperm concentration was low in 90.6% of samples; total necrospermia was found in 65% and asthenospermia in 95% of samples. CONCLUSION: Ejaculation is difficult to induce using VM in patients with CE and CM lesions, and requires high doses of midodrine. Sperm counts were generally low, and asthenospermia and necrospermia were found in the majority of specimens. Cryopreservation of sperm should be systematic in case of medically assisted procreation.

[The impact of mellitus diabetes on the lower urinary tract: A review of Neuro-urology Committee of the French Association of Urology]. / Le retentissement du diabète sur le bas appareil urinaire : une revue du comité de neuro-urologie de l'Association française d'urologie.

OBJECTIVES: Specify urinary functional impairment associated with diabetic pathology. Propose guidance for screening, monitoring of clinical signs of lower urinary tract (LUTS) and describe the specifics of the urological treatment of patients. METHODS: A review of literature using PubMed library was performed using the following keywords alone or in combination: "diabetes mellitus", "diabetic cystopathy", "overactive bladder", "bladder dysfunction", "urodynamics", "nocturia". RESULTS: LUTS are more common in the diabetic population with an estimated prevalence between 37 and 70 %, and are probably underevaluated in routine practice. They are heterogeneous and are frequently associated with other diabetic complications. Both storage and voiding symptoms can coexist. Despite a major evaluation in the literature, no recommendation supervises the assessment and management of LUTS in this specific population. An annual screening including medical history, bladder and kidney ultrasound and post-void residual measurement is required in the follow-up of diabetic patients. Specific urologial referral and urodynamic investigations will be performed according to the findings of first-line investigations. The type of bladder dysfunction, the risk of urinary tract infections and dysautonomia should be considered in the specific urological management of these patients. CONCLUSION: Diabetes mellitus significantly impacts on the lower urinary tract function. A screening of LUTS is required as well as other complications of diabetes. The management of LUTS must take into consideration the specific risks of the diabetic patient regarding the loss of bladder contractility, the possibility of dysautonomia and infectious complications.

[Definition of botulinum toxin failure in neurogenic detrusor overactivity: Preliminary results of the DETOX survey]. / Définition et prise en charge de l'échec d'une première injection de toxine botulique Botox ® 200 U pour hyperactivité détrusorienne neurogène: résultats de l'enquête DETOX.

OBJECTIVE: There is currently no guideline regarding the management of neurogenic detrusor overactivity (NDO) refractory to intra-detrusor botulinum toxin injections. The primary objective of the present study was to find a consensus definition of failure of botulinum toxin intra-detrusor injections for NDO. The secondary objective was to report current trends in the managment of NDO refractory to botulinum toxin. METHODS: A survey was created, based on data drawn from current literature, and sent via e-mail to all the experts form the Group for research in neurourology in french language (GENULF) and from the comittee of neurourology of the French urological association (AFU). The experts who did not answer to the first e-mail were contacted again twice. Main results from the survey are presented and expressed as numbers and proportions. RESULTS: Out of the 42 experts contacted, 21 responded to the survey. Nineteen participants considered that the definition of failure should be a combination of clinical and urodynamics criteria. Among the urodynamics criteria, the persistence of a maximum detrusor pressure>40 cm H2O was the most supported by the experts (18/21, 85%). According to the vast majority of participants (19/21, 90.5%), the impact of injections on urinary incontinence should be included in the definition of failure. Regarding the management, most experts considered that the first line treatment in case of failure of a first intra-detrusor injection of Botox(®) 200 U should be a repeat injection of Botox(®) at a higher dosage (300 U) (15/20, 75%), regardless of the presence or not of urodynamics risk factors of upper tract damage (16/20, 80%). CONCLUSION: This work has provided a first overview of the definition of failure of intra-detrusor injections of botulinum toxin in the management of NDO. For 90.5% of the experts involved, the definition of failure should be clinical and urodynamic and most participants (75%) considered that, in case of failure of a first injection of Botox(®) 200 U, repeat injection of Botox(®) 300 U should be the first line treatment.

Sites of electrical stimulation used in neurology.

Rehabilitation aims to decrease neurological impairments, in guiding plasticity. Electrical stimulation has been used for many years in rehabilitation treatment of neurological disabilities as a tool for neuromodulation inducing plasticity, although the mechanisms of its action are not well known. The applications vary, encompassing therapeutic and rehabilitative aims. The type and site of stimulation vary depending on the objectives. Some techniques are widely used in clinical practice; others are still in the research stage. They may be invasive, epidural or in direct contact with neurons; they may be noninvasive, applied transcutaneously or indirectly by current vectors. The indications vary: mobility, functionality, pain as well as pharyngeal, respiratory, and perineal function. This paper aims to summarize current data on electrical neuromodulation techniques used in neurorehabilitation, their effects and their mechanisms of action.

[The role of urinary markers in the assessment and follow-up of lower urinary tract disorders: a literature review]. / Place des biomarqueurs urinaires dans le diagnostic et le suivi des troubles du bas appareil urinaire: une revue de la littérature.

OBJECTIVES: To conduct a literature review on the role of urinary biomarkers in the initial assessment and follow-up of lower urinary tract symptoms. METHODS: A literature review was conducted in August 2014 using the Medline/Pubmed database limiting the search to work in English or French. RESULTS: Most studies were of level of evidence 2 or 3 (prospective cohort, controlled or not) and mainly about overactive bladder and bladder pain syndrome. Nerve Growth Factor (NGF) was the most studied and apparently the most promising in the evaluation of overactive bladder (OAB) and neurogenic detrusor overactivity (NDO). Urinary levels of ATP, prostaglandin E2 (PGE2), Brain-Derived Neurotrophic Factor (BDNF) and some cytokines were also significantly higher in most studies in patients with NDO or OAB. Epidermal Growth Factor (EGF), Heparin-Binding EGF (HBEGF) and Antiproliferative Factor (APF) were the most studied urinary markers in bladder pain syndrome, with a significant increase (EGF APF) or decrease (HBEGF) in cases of interstitial cystitis (compared to healthy controls). The urinary N-terminal-telopeptide (NTx) could be predictive of a failed mid-urethral sling. However, few studies reported the diagnostic values of the markers, their association with urodynamic parameters were rarely evaluated and the existence of a publication bias is likely. No randomized controlled study has so far compared the urinary markers to urodynamic evaluation. CONCLUSION: In the future, urinary markers could complete or replace urodynamic examination. However, to date, there is no high level of evidence study comparing these markers to urodynamics and their use can therefore not be recommended in daily practice.

[Study of the sensitivity of renal ultrasonography as an indirect means of assessing renal function in patients with neurogenic bladder, from a cohort of 103 patients]. / Étude de la sensibilité de l'échographie rénale comme moyen indirect d'évaluation de la fonction rénale chez les patients porteurs d'une vessie neurologique, à partir d'une cohorte de 103 patients.

OBJECTIVES: The assessment of renal function is essential to follow up the patients with neurogenic bladder. The objective of this study was to determine if renal ultrasonography would both evaluate the morphology of the urinary tract and renal function. METHOD: In a retrospective study, all patients followed for neurogenic bladder were included, regardless of their neurological disease. Renal function was estimated by creatinine clearance (Cl24 h), the reference test in neurological patients, the glomerular filtration rate by the MDRD simplified (MDRDs) and CKD-EPI creatinine formula, and we identified renal abnormalities detected on ultrasonography. RESULTS: One hundred and three patients were included (57 men-36 women), mean age 51±13 years. Fifty-nine patients had multiple sclerosis, 23 spinal cord injury. Depending on the method used (Cl24h, MDRDs, CKD-EPI creatinine) respectively 54, 49 and 39 patients had abnormal renal function; eleven patients had abnormal findings on renal ultrasonography. The sensitivity of ultrasonography as an indirect indicator of renal function depending on the method used (Cl24h, MDRDs, CKD-EPI creatinine) was equal respectively to 14%, 8% and 10%. CONCLUSION: Renal ultrasonography, which is essential to follow up the neurogenic bladder, is not enough sensitive to detect abnormal renal function and should continue to be associated with an evaluation of renal function, which is suitable for neurological patients. LEVEL OF EVIDENCE: 4.

Post-stroke hemiplegia rehabilitation: evolution of the concepts.

Stroke rehabilitation has undergone a revolution over the last three decades. Cohort studies have consistently reinforced the importance of post-stroke rehabilitation to stimulate recovery, but the concepts of empirical methods originally proposed by therapists to rehabilitate these patients have not withstood clinical analysis. Functional neuroimaging and animal models have unveiled the mechanisms underlying functional recovery and helped teams understand its limitations and improvement modalities. These neuroscience discoveries constitute the grounds needed to understand the emergence of new technologies: robotics and virtual reality. The objective of this review of the literature was to select key works in this field to better understand current therapeutic possibilities.
