[Bladder augmentation in the era of botulinum toxin: Indications and results]. / L'entérocystoplastie d'agrandissement à l'ère de la toxine botulique : indications et résultats.

AIM: To determine the surgical indication and results of bladder augmentation (BA) during the last decade in a neurourology center in the era of intradetrusor botulinum toxin injection. MATERIAL: We conducted a retrospective study that included patients with BA between January 1, 2012 and December 31, 2022 in our centre. We collected pre-operative demographic, clinical, and urodynamic data, BA indication, and associated procedures. We analyzed early and late complications as well as continence and postoperative voiding mode in patients with first BA in a neurological pathology context. RESULTS: We performed 77 BA over the study period. The main indication was neurogenic overactive bladder, which was secondarily resistant to botulinum toxin. The main associated procedure was continent cutaneous diversion (n=31, 57.4%). Among patients who had a first BA for neurogenic bladder, 34 patients had early complications (50%) including 12 patients with≥Clavien 3 complications (17.6%). After a median follow-up of 33 [14; 55] months, 23 patients had late complications (33.8%) and 59 patients had complete continence (86.8%). CONCLUSION: In the era of botulinum toxin, the main indication of BA is the secondary failure of botulinum toxin for overactive neurogenic bladder. The BA provided continence in 86.8% of patients. It remains however an intervention with a significant rate of severe complications whose indication must be discussed by a multidisciplinary team. LEVEL OF EVIDENCE: Weak.

[Uroflowmetry: A follow-up tool for neurogenic bladder patients treated by transcutaneous tibial posterior stimulation?] / Débitmétrie : outil de suivi chez les patients avec vessie neurologique traités par neurostimulation tibiale postérieure ?

OBJECTIVE: Neurogenic bladders can suffer from overactivity, underactivity or dyssynergia depending on the level of the initial lesion. These symptoms can lead to severe alterations of the upper urinary tract. One of the first-line treatments is the transcutaneous tibial posterior stimulation (TTNS), which was demonstrated to be efficient on urodynamics. But it is an invasive, expensive and sometimes not patient-accepted examination, contrary to the uroflowmetry. The aim of this study is to assess the feasibility of a follow-up with a uroflowmetry when treated by TTNS and show that the maximum flow rate increased after treatment, displaying a better detrusor contraction. METHODS: In total, 38 patients with neurogenic bladder undergoing a 12-weeks TTNS treatment and with 2 uroflowmetries interpretable before and after treatment were included. The maximum flow rate (Qmax), the urinated volume and the post-void residual (PVR) were retrieved from the uroflowmetry, and the USP-score and the urinary discomfort were asked at each appointment. RESULTS: Qmax is increased from 17,53ml/s to 18,26ml/s, as well as the PVR (from 76,97ml to 79,16ml). Urinated volume is decreased from 241,4ml to 193,66ml. Patients feel enhanced after TTNS according to the decrease in the USP-score and the urinary discomfort scale. CONCLUSION: The increase of the cystomanometric capacity and the delay of the detrusor overactivity due to TTNS explains the reduction of the urinated volume and the increase of PVR. Increased Qmax might show a better voluntary bladder contraction, with a restraint due to the lack of abdominal pressure measurement during voiding.

[Neurogenic bladder and continent cystostomy: Results of a monocentric cohort in a French university hospital]. / Vessies neurologiques et cystostomie continente : résultats d'une cohorte monocentrique dans un centre hospitalier français.

OBJECTIVE: The main objective was to evaluate the complications of continuous urinary shunts in a French university hospital according to surgical technique and functional results especially on continence. The secondary objective was to evaluate the management of complications. METHODS: A retrospective study was conducted between January 2008 and August 2017. Patients who had a continent cystostomy with or without bladder augmentation were included. Diversions for non-neurological causes were excluded. Cystostomy was performed using the appendix or a Monti's artifice. Data collected included complications and their management, functionality of the diversion and of the bladder reservoir, cystostomy continence, and urethral continence. RESULTS: Nineteen patients were included. The median follow-up time was 46 months. The majority of early postoperative complications were classified as grade II Clavien-Dindo. No postoperative deaths occurred. Late complications most frequently involved cystostomy duct stenosis (n=5), cystostomy incontinence (n=5), and urethral incontinence (n=8). Thirteen patients had revision surgery for late complications. Late complications on continence evolved favorably after revision surgery or medical treatment in all, but one case. CONCLUSION: Our results are consistent with the literature. Complications and the re-interventions are frequent and should lead to a multidisciplinary information and evaluation of the patient in preoperative care. LEVEL OF PROOF: 3.

[External sphincterotomy in neurological patients with detrusor sphincter dyssynergia: Short and mid-term results]. / Résultat à court et moyen terme du traitement de la dyssynergie vésico-sphinctérienne par sphinctérotomie endoscopique.

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.

Aqua: A new questionnaire assessing anticholinergic side effects in neurogenic population (Aqua: Anticholinergic side effects questionnaire).

AIMS: Validate a new questionnaire to assess the side effects secondary to anticholinergics in neurogenic population suffering from Adult neurogenic lower urinary tract dysfunction (ANLUTD). METHODS: We conducted a prospective, monocentric study in a Neuro-urology Department of a University Hospital between February 2015 and April 2020. To allow a full psychometric validation of a questionnaire, the study protocol included 3 steps: qualitative interviews, feasibility study and validation study. The primary outcome was good psychometric properties defined with good internal consistency reliability (Cronbach's α>0.7) and good test-retest reliability (intraclass correlation coefficient (ICC)>0.7). RESULTS: we included 64 patients with ANLUTD secondary to neurogenic disorders. Feasibility study demonstrate very good acceptation and comprehension for 97% of patients. Validation study showed good internal consistency with Cronbach's α=0,69 and very good ICC=0,73. AQUA is composed with 8 items scoring 0 (no side effect) to 2 (major side effect) for a total score between 0 to 16. Time to fulfill is very quick. Mean score in our population was 4,1 (sd 2,9). CONCLUSION: AQUA is the first validated tool to assess side effects secondary to antimuscarinic treatment for neurogenic population suffering from ANLUTD. LEVEL OF PROOF: 2.

Quality of life in neurogenic patients based on different bladder management methods: A review.

OBJECTIVE: To determine the overall quality of life and patient satisfaction associated with different bladder management strategies in neuro-urological patients. The second objective was to identify other associated factors that may further influence the patient's quality of life. DESIGN: Systematic Review. METHODS: Studies from Pubmed, Cochrane, and Google Scholar databases were extracted using terms relating to 'quality of life', 'satisfaction', in 'neurogenic bladder' combined with 'bladder management methods' that included 'continent and non-continent urine diversion', 'intermittent-catheterization', 'indwelling catheter' and 'condom-catheter'. Only studies with a minimal proportion of 80% of neurogenic bladder patients were included. Search was conducted, and article titles and abstracts were rated. 136 papers were screened and assessed for eligibility. RESULTS: 25 studies were included in the final analysis and consisted of ten retrospective, nine prospective, five cross-sectional and a single randomized controlled trial. In total, 3002 patients were included, with a majority of male (55%) and spinal cord injury (88%) patients. 167 patients had incontinent urinary diversions, 464 had continent urinary diversions (bladder augmentation with or without cutaneous catheterizable channel), 1698 used intermittent catheterization (self or by an attendant), 550 had an indwelling catheter (urethral or suprapubic), and 123 had condom catheters. Quality of life was assessed using a wide variety of validated and non-validated questionnaires. Overall, patients with continent and incontinent diversion tended to have better scores. Use of catheters tended to have more unsatisfactory scores, with indwelling and attendant-intermittent catheterization often scoring worse. On the other hand, patients using self-intermittent catheterization tended to fair well. CONCLUSION: Normal micturition followed by self-catheterization yielded an overall higher quality of life. Data were too divergent to rank the other bladder management methods. However, by improving continence, each method aims to enhance quality of life.

Repeated detrusor injection of botulinum toxin A for neurogenic bladder in children: A long term option?

AIMS: Evaluation of repeated (at least 4) intra-detrusor injections of toxin botulinum A (IDI-TBA) for neurogenic bladder in a pediatric cohort. METHODS: Patients who underwent at least 4 IDI-TBA between 2005 and 2017 for neurogenic bladder related issues were included (detrusor overactivity and low compliance). Clinical and cystometric data were collected before and after the first injection and after the last injection. The primary endpoint was the proportion of patients with non-abnormal cystometry (no detrusor overactivity and normal compliance). Secondary outcomes were the evolution of the observed bladder capacity/expected ratio, surgical complications and acquired kidney impairment. RESULTS: From the 832 patients referred to our institution for neurogenic bladder, 48 underwent IDI-TBA, and 17 at least 4 injections. Among them, a total of 95 procedures were performed (median per patient 5 [4-8]). While the first injection had a significant effect for 82.3% patients, the last injection improved the medical condition for only 53.0% cases. The bladder capacity ratio, initially 36.1%, increased to 80.3% after the first injection but decreased to a level of 57.1% at last. After a median follow-up of 57 [34-102] months, no severe complications were reported but 11.8% of patients presented with repeated pyelonephritis. A bladder augmentation surgery was finally indicated for 35.3% cases. CONCLUSIONS: Despite a low complication rate and impressive cystometric results after the first injection, IDI-TBA efficacy decreased with time and repetition. These findings prone a long-term follow-up and a "à-la-carte" management of this specific population depending on the long-term response to IDI-TBA.

[Evaluation of management of patients under clean intermittent catheterization by general practitioners]. / Évaluation de la prise en charge des patients sous sondage intermittent propre par les médecins généralistes.

INTRODUCTION: Clean Intermittent Catheterization (CIC) is the method of choice for bladder emptying in patients having bladder emptying disorders, acquired or pharmacologically induced, whether it is neurologically related or not. The aim of this study is to assess the theoretical and practical knowledge of general practitioners (GP) on CIC. MATERIALS: Observational prospective study (anonymous online questionnaire) was conducted with 224 GP between March and April 2020. Each physician had to complete a questionnaire about the definition of CIC, its indications and usage, the indications of urine culture, antibiotic therapy, and the complications of this method of drainage. RESULTS: Only 18.3% of GP that took part in the study gave an exact definition of CIC. As to the importance of it, 67.9% responded that it protects the upper urinary tract and 37.1% that it prevents urinary tract infections (UTI). Fifty-two per cent of physicians were unaware of the regular frequency at which it should carry out a day. Fifty eight percent prescribed sterile gloves and 57.1% an antiseptic. UTI was considered as the main complication of CIC by 87.1% of physicians and 35.7% requested a systematic urine culture for patients under CIC. For patients with an asymptomatic bacteriuria, 65.6% of GP prescribed antibiotic therapy. CONCLUSION: GP need to improve their knowledge of SIP, its framework, indications, modalities, and the way to deal with colonization or urinary tract infection. This will improve the management of impacted patients.

[Safety and efficacy of percutaneous nephrolithotomy in patients with neurogenic bladder]. / Néphrolithotomie percutanée chez les patients neurologiques : efficacité et morbidité à long terme.

INTRODUCTION: To assess the efficacy and morbidity of percutaneous nephrolithotomy (PNLT) in the treatment of renal stones in patients with neurogenic lower urinary tract dysfunction (NLUTD). METHODS: Retrospective, monocentric study including all patients with NLUTD who had undergone PNLT between 2005 and 2017. Pre-operative clinical data (neurological condition, voiding mode, preoperative urine culture…), peri-operative and post-operative data (success and morbidity) were collected from the patients' charts. Success was defined by the absence of residual fragment (RF), on imaging or intraoperative endoscopy. Partial efficacy was defined by the presence of RF lower than 4mm. Early complications were reported according to the Clavien-Dindo classification. RESULTS: In all, 53 PNLTs were performed, in 35 patients, mostly with spinal cord injury. The success and partial efficacy rates were 66.0% and 71.7% respectively. The failure rate was correlated with increased stone burden (P=0.03), increased size of the largest stone (P=0.02), and the presence of complex stones (P<0.02). The rate of early complications was 41.5%, with 27.3% major, mostly septic, and bleeding. The retreatment rate within 3 years was 41.5%. CONCLUSION: In patients with NLUTD, PNLT allows a high success rate, but with a significant rate of retreatment and infectious complications. However, NLPC remains the gold standard in this population, especially for renal stones larger 20mm, allowing a higher success rate than ureteroscopy and a lower retreatment rate.

[Intradetrusor injections of botulinum toxin A to treat urinary incontinence due to bladder overactivity during idiopathic Parkinson's disease]. / Injections intradétrusorienne de toxine botulique A (onabotuliniumtoxin A) pour traiter l'incontinence urinaire par urgenturie au cours de la maladie de parkinson idiopathique.

INTRODUCTION: During idiopathic Parkinson's disease (IPD), lower urinary tract symptoms and dysfunctions are frequent, dominated by overactive bladder and detrusor overactivity (OAB, DO). Intradetrusor Injection (IDI) of Botulinum Toxin A (BTA) is recommended as second-line treatment for neurogenic urinary incontinence related to DO in multiple sclerosis or spinal cord injury patients. However, there is little data on BTA IDI to treat incontinence owing to OAB and DO during idiopathic Parkinson's disease. The objective of this study is to evaluate efficacy and tolerance of BTA IDI in patients suffering IPD. PATIENTS AND METHODS: We conducted a retrospective study in IPD patients treated with BTA IDI from 2012 to 2018. For each patient we compared patient clinical and urodynamic data at baseline before the first injection and 8 weeks following the injection. We defined 3 levels of effects (perfect, improved, failure), corresponding to 3-dimension composite criteria: clinical, quality of life (Likert scale), urodynamics. RESULTS: Sixteen patients were included from 2012 to 2018. The median age was 73 (70-78.25). The median number of micturition/day before and after TBA was 13 (10-16) and 9 (6.75-13.25) (p=0.022). The median number of pad used/day before and after BTA was 5.4 (2-5) and 1 (0-5) (p=0.035). Median USP scores for OAB was 15.5 (11.75-20) and 14 (6.75-15.25). Median score on the Likert scale was 1 (0-1.5) meaning "slight improvement" felt by the patient. The median maximum cystometric capacity raised from 130cm3 (41.25-187.75) to 217cm3 (165-376.75) (p=0,013). Among the patients, 20% had a perfect result, 40% were significantly improved and in 40% TBA injections failed. After TBA 4/14 patients (28%) needed intermittent self-catheterization. No severe side effect was observed. CONCLUSION: In this retrospective study we observe some short-term efficacy of TBA IDI to treat urinary incontinence owing to OAB/DO in patients with IPD in 60% of patients. These results are consistent with findings from previous retrospective studies. Prospective data coming from larger cohorts are now tremendously needed to clarify the best patient responders profiles, the actual TBA dose, and eventually to define TBA IDI place in the therapeutic algorithm of IPD patients' incontinence.

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.

[French Association of Urology. COVID-19: Recommendations for functional urology]. / Recommandations jointes des comités de l'AFU (neuro-urologie, CUROPF, CTMH) pour l'urologie fonctionnelle durant la crise sanitaire liée au COVID-19.

AIM: The management of urology patient is currently disrupted by the COVID-19 epidemic. In the field of functional urology, there are clinical situations with a high risk of complication if management is delayed and a great heterogeneity of advisable reprogramming times after cancellation. A prioritization of functional urology procedures is necessary to adapt management during the COVID-19 crisis and to better organize post-epidemic recovery. MATERIAL AND METHODS: The advice of AFU scientific committees in the field of functional urology (neuro-urology, female and perineology, male LUTS) was requested and supplemented by a review of the currently available recommendations on the subject of urology and COVID-19. These opinions were combined to draw up temporary recommendations to help reorganize practices during the epidemic and prepare the post-critical phase. RESULTS: Most of the recommendations available on career-oriented social networks (Twitter, LinkedIn) or in literature concern cancer or general urology. Eight out of ten propose a cancellation of all functional urology procedures without distinction. But the 3 AFU committees covering the field of functional urology have identified three clinical situations in which surgical procedures that can be maintained during the COVID-19 epidemic (priority level A): conclusion of a neuromodulation test in progress (implantation or explantation), botulinum toxin A bladder injections for unbalanced neurologic bladder, cystectomy and ileal conduit for urinary fistula in perineal bedsore or refractory unbalanced neurologic bladder with acute renal failure and vesico-enteric or prostato-pubic fistulas. Management adaptation of the other pathologies are proposed, as well as the application of 3 priority levels (B, C, D) for rescheduled procedures for a better management of the post-crisis activity resumption. CONCLUSION: The joint functional urology committees indicate that there are specific clinical situations in this field that demand non-delayed care during COVID crisis. They underline the need to establish a hierarchy for the cancelled surgeries, in order to reduce the arm of long reschedule delays and to optimize post-lockdown activity resumption.

Efficacy and security of continent catheterizable channels at short and middle term for adult neurogenic bladder dysfunction.

AIMS: The objective of this study was to assess the effectiveness and the complications rate following continent cutaneous channels (CCC) procedures, at short and medium term follow-up (FU). MATERIALS & METHODS: A continuous retrospective case series (2008-2018): all patients who have undergone a CCC for neurogenic bladder were included in our department. The primary outcome was the effectiveness of CCC defined by the status of catheterizability (by the patient or a care-giver), continence of the tube, and absence of reintervention at 3 and 12 months FU. The secondary outcome was the prevalence of postoperative complications at 3 and 12 months FU. RESULTS: Fifty-three patients were included during the study period in our department. Median follow up was 3,3 years (1.5-6.1). The overall effectiveness of CCC was 67.9% (n=36/53) at 3 months FU and 45,3% (n=24) at 12 months FU. The global rate of complications was 60.4% (n=32/53) at 3 months, and 73.6% (n=39/73) at 12 months FU. The statistical analysis showed no statistical differences on efficacy and complications in the different subgroups of CCC. CONCLUSIONS: In the current series, the effectiveness and the complications rates following CCC were comparable across the procedure types. LEVEL OF EVIDENCE: 4.

[Temporary urethral stents changes as an alternative treatment for neurological bladder]. / Les changements itératifs de prothèse urétrale trans-sphinctérienne chez le patient neurologique : une alternative à la sphinctérotomie ?

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.

[Interest of transcranial stimulation in pelvic and perineal disorders]. / Intérêt de la stimulation transcrânienne dans les troubles pelvi-périnéaux.

OBJECTIVE: The aim of this article was to describe the diagnostic and therapeutic value of transcranial stimulation in pelvic and perineal disorders. METHODS: A literature review (Medline database and Google scholar) with no time limit was performed using keywords: "transcranial direct stimulation", "transcranial magnetic stimulation", "neurogenic bladder", "urinary incontinence", "Parkinson disease", "multiple sclerosis", "stroke", "muscle spasticity", "pelvic pain", "visceral pain". RESULTS: Twelve articles have been selected. Transcranial magnetic or electrical stimulation is a noninvasive neuromodulation technique widely used to establish brain maps to highlight causal relationships between brain and function. Regarding pelvic-perineal disorders, repeated transcranial stimulation has shown significant effects for the treatment of overactive bladder in Parkinson's disease (P<0.05) and multiple sclerosis, but also for the treatment of refractory chronic pelvic pain (P=0.026). Finally, therapeutic effects have also been demonstrated in irritable bowel syndrome. No evidence of efficacy was found on genito-sexual disorders. CONCLUSION: Data from the literature suggest that transcranial stimulation is a noninvasive treatment that may have a role in the management of pelvic and perineal disorders. Its promising field of action would require prospective and randomized studies on a larger scale.

[Original strategy for prevention of recurrent symptomatic urinary tract infections in patients with neurogenic bladder: Bacterial interference, state of the art]. / Stratégie préventive originale des infections urinaires symptomatiques chez les patients porteurs d'une vessie neurologique : l'interférence bactérienne, état de l'art.

PURPOSE: Urinary tract infection (UTI) is the most common complication in patients with neurogenic bladder. The long-term use of antibiotic drugs induces an increase in antimicrobial resistance and adverse drug reactions. Bacterial interference is a new concept to prevent recurrent UTI which consists in a bladder colonization with low virulence bacteria. We performed a literature review on this emerging therapy. MATERIALS AND METHODS: Literature review of bacterial interference to prevent symptomatic urinary tract infection in neurological population. RESULTS: Seven prospectives study including 3 randomized, double-blind and placebo controlled trial were analyzed. The neurological population was spinal cord injured in most cases. The bladder colonization was performed with 2 non-pathogen strains of Escherichia coli: HU 2117 and 83972. At 1 month, 38 to 83% of patients were colonized. Mean duration of colonization was 48.5 days to 12.3 months. All studies showed that colonization might reduce the number of urinary tract infections and is safe with absence of serious side effects. CONCLUSION: Bacterial interference is a promising alternative therapy for the prevention of recurrent symptomatic urinary tract infections in neurogenic patients. This therapy should have developments for a daily use practice and for a long-term efficacy.

[Bladder cancer in neurogenic patients: A retrospective study of management and follow-up]. / Cancers de vessie chez les patients neurologiques : étude rétrospective de prise en charge et de suivi.

INTRODUCTION: The prevalence of bladder cancer (BC) in neurological patients seems to be similar to that of the general population. However, they are more aggressive with a higher rate of muscle-invasive forms and squamous cells carcinomas. The aim of the current study was to report etiologies, management and outcomes of BC in neurological population. MATERIAL AND METHOD: Were enrolled all neurological patients with a BC diagnosed between 2004 and 2017. The following data were retrospectively reported: age, gender, duration of the disease, mode of discovery, histological type, treatment and outcomes. RESULTS: In total, 27 patients were included: 11 spinal cord injuries, 7 Parkinson's disease, 5 multiple sclerosis, 3 head trauma, 3 brain strokes, 2 cerebral palsies and 1 spina bifida. The histological subtypes were as follows: 22 transitional cells carcinomas, 4 squamous cell carcinomas (SCC), one mucinous adenocarcinoma, one sarcomatoid and one neuroendocrine with 19 high-grade tumors and 15 muscle-invasive bladder cancer. Seven patients (26%) were diagnosed before 15 years history of neurogenic bladder. The mean follow-up was 14 months (1-210 months). Eight deaths were observed, with 5 related to bladder cancer. In our study, smoking habits, voiding mode, lithiasis or infection histories were not related with a more aggressive pattern, such as SCC. CONCLUSION: The high rate of muscle-invasive bladder cancer and aggressive patterns justify neuro-urological follow-up, even before 15 years of neurogenic bladder. LEVEL OF EVIDENCE: 4.

[Reproducibility of bladder diary in patients with multiple sclerosis]. / Reproductibilité du calendrier mictionnel chez les patients atteints de sclérose en plaques. Étude prospective monocentrique.

INTRODUCTION: Multiple sclerosis (MS) is a neurological condition characterized by variable levels of symptoms. This variability could also affect bladder dysfunction and impact on the reproducibility or stability of bladder diary (BD). The aim of the study is to investigate the reproducibility and reliability of BD in MS, and then determine its linked factors. METHODS: The MS patient provided a 21 days BD and they documented the time of every void. The main criterion was assessed by voiding frequency, represented by the coefficient of variation (CV=average/standard deviation), expressed as a percentage. Two groups were described: stable BD group (CV≤15 %) and instable BD group (CV>15 %). Secondary criteria were completion of BD (complete or not) and the difference of voiding frequency variation between weekend and week. RESULTS: Thirty-one patients were included (mean age 51.06 years, SD 11.33) with 65 % of women. Mean CV is 23 % (SD 0.11). The mean completion of BD was 19.35 days (SD 3.99). 8 patients had a CV≤15 %. Stable group was older than instable group (P=0.03). There was no other difference between the 2 groups. There is a strong correlation between mean voiding frequency weekend and week (ρ=0.94, P<0.05). The longer duration of BD, the less reliability is notified. CONCLUSION: BD is not a stable reproducible in MS population. Both lack of compliance or variability of LUTS in MS may explain the unreliability of BD. However, BD utility should be discussed in this population. LEVEL OF EVIDENCE: 4.

[Pregnancy and delivery for women with congenital spinal cord defects and neurogenic bladder]. / Conséquences urologiques de la grossesse et de l'accouchement chez les patientes porteuses d'une vessie neurologique par anomalie congénitale médullaire.

INTRODUCTION: Data are scarce regarding pregnancy and delivery among women with a neurogenic bladder due to congenital spinal cord defects. OBJECTIVE: To report the obstetrical and urological outcomes of women with congenital spinal cord defects and vesico-sphincteric disorders. METHODS: A retrospective multicentric study included all consecutive women with a neurogenic bladder due to congenital spinal defects, who delivered between January 2005 and December 2014. The following data were collected: demographics, neuro-urological disease characteristics, urological and obstetrical history, complications during pregnancy, neonatal outcomes, and changes in urological symptoms. RESULTS: Overall, sixteen women, median age 29,4 years old (IQR 22-36), had a total of 20 pregnancies and 21 births (15 caesareans, 5 vaginal deliveries). Prior to the beginning of their first pregnancy, 12 patients were under intermittent self-catheterization. Symptomatic urinary tract infections during pregnancy occurred in 11 pregnancies, including 4 pyelonephritis. In 4 women, stress urinary incontinence had worsened but recovered post-partum. In 3 women, de novo clean intermittent catheterization became necessary and had to be continued post-partum. During 3 pregnancies, anticholinergic treatment had been started or increased because of urge urinary incontinence worsened. These changes were maintained after delivery. The median gestational age at birth was 39.0 weeks (IQR 37.8-39.5). There were 15 caesarean sections, of which 9 were indicated to prevent a potential aggravation of vesico-sphincteric disorders. Among the 5 pregnancies with vaginal delivery, there was no post-partum alteration of the sphincter function. CONCLUSION: Successful pregnancy outcome is possible in women with congenital spinal cord defects and vesico-sphincteric disorders but it requires managing an increased risk of urinary tract infections, caesarean section, and occasionally worsened urinary incontinence. LEVEL OF EVIDENCE: 5.
