RESUMO
INTRODUCTION: Multiple sclerosis (MS) is often associated with urological disorders, mainly urinary incontinence and retention, the management of which being necessary to improve patient's quality of life (QOL) and to reduce potential urological complications. Besides the classical treatments based mainly on anticholinergics and/or self-catheterization, several neuromodulation techniques have been tried in recent years to improve these urinary disorders. By this review, we aim at providing an overview of neuromodulation and electrostimulation approaches to manage urinary symptoms in MS patients. MATERIALS AND METHODS: A literature search using MEDLINE was performed. Only papers in English, and describing the effects of neuromodulation in MS patients, were considered. RESULTS: A total of 18 studies met inclusion criteria and were reviewed. Of them, four related to sacral neuromodulation (SNM), seven to percutaneous tibial nerve stimulation (PTNS), six to spinal cord stimulation (SCS), and one to transcranial magnetic stimulation (TMS). DISCUSSION: PTNS and SNM seem to be effective and safe therapeutic options for treating lower urinary tract symptoms in MS patients principally in case of overactive bladder (OAB) symptoms. Similarly, also SCS and TMS have been shown to be effective, despite the very limited number of patients and the small number of studies found in the literature. Interestingly, these techniques are effective even in patients who do not respond well to conservative therapies, such as anticholinergics. Furthermore, given their safety and efficacy, stimulations such as PTNS could be considered as a first-line treatment for OAB in MS patients, also considering that they are often preferred by patients to other commonly used treatments.

AIMS: To measure the time required to perform clean intermittent self-catheterization (CISC) in daily life and to assess its impact on adherence and quality of life. METHODS: Patients performing CISC for more than 1 month were invited to participate. At home, patients were asked to complete a 1-day diary to assess the specific duration of the CISC (time from when the equipment and environment are brought together to perform CISC) and the next day to complete a second diary for the total duration of the CISC (starting when the patient intent to self-catheterize to the return to the initial activity, including the displacement, and gathering the required device). Adherence, difficulties with CISC, and quality of life were measured with validated questionnaires: Intermittent Catheterization Satisfaction Questionnaire, Intermittent Catheterization Difficulty Questionnaire, Intermittent Catheterization Adherence Scale, and SF Qualiveen Questionnaire. RESULTS: Thirty-six patients agreed to participate but only 25 patients completed the entire protocol. The participants performed CISC for an average of 7 years. The median specific duration of CISC was 2 min and 23 s (ranging from 47'' to 11'50''). The median total duration of CISC was 3 min and 40 s (1'35''; 18'47''). No significant correlation was found between the duration of CISC and patient characteristics, adherence, difficulty to self-catheterize, or quality of life. CONCLUSION: The time to perform CISC was brief, and less than 2-3 min on average. The impact on adherence and quality of life should be assessed in a larger cohort.

AIMS: The primary aim of this study was to assess the relationship between a strong desire to void (SDV) and rectal sensory function in patients with multiple sclerosis (PwMS) and anorectal disorders. The secondary aim was to identify clinical, urodynamic or manometric factors associated with greater rectal sensory function impairment in this population. METHODS: Thirty PwMS (mean age 49.2 ± 10.9 years) with anorectal disorders (constipation and/or fecal incontinence) participated in this observational study. Rectal sensory parameters during anorectal manometry were recorded at a strong desire to void and after urination (PV, post-void). The primary outcome was the desire to defecate volume. Secondary outcomes were first perception and maximum tolerated threshold volumes, presence and modulation of recto-anal inhibitory reflex. RESULTS: The mean desire to defecate volume was 125 ± 59 mL at SDV and 104 ± 64 mL at PV (P < .001). The mean maximum tolerated volume was 167 ± 61 mL at SDV vs 141 ± 64 mL after urination (P = .01). The other parameters were not different between SVD and PV conditions. No predictive factors for greater impairment of rectal sensory function were identified. CONCLUSION: This study suggests a relationship between bladder sensation and thus bladder capacity, and rectal sensory function in PwMS and with anorectal disorders.

BACKGROUND: Assessment of motor and cognitive functions is recommended before clean intermittent catheterization training. Two validated instruments, the Functional Independence Measure (FIM) and the Pencil and Paper Test (PP-Test), are associated with the ability to learn self-catheterization in people with multiple sclerosis. OBJECTIVES: We aimed to compare the performance of these tools in predicting the outcome of clean intermittent catheterization training in multiple sclerosis. METHODS: All people with multiple sclerosis attending a tertiary neuro-urology department between 2011 and 2019 and eligible for clean intermittent catheterization were included in this retrospective study. The reference standard was the ability to perform at least 2 trials of self-catheterization at the end of the training session. The 2 index tests, the FIM and PP-Test, were administered before the teaching session. Their diagnostic performance was estimated by calculating sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). The AUC values were compared by a two-sided DeLong test. RESULTS: We included 395 individuals (mean [SD] age 49.8 [12] years; 70% women). At the end of the session, 87% of the patients succeeded in learning self-catheterization. The optimal cut-offs for the FIM (107) and PP-Test (13) were estimated, resulting in sensitivity of 73% (95% confidence interval [68-77) and 73% (67-77) and specificity 73% (59-84) and 63% (49-76), respectively. The AUC values for the FIM and PP-Test were significantly different (0.79 vs 0.73, p = 0.049). The effect size was large for both the FIM (Cohen's d = 1.14) and PP-Test (Cohen's d = 0.87). CONCLUSIONS: An FIM value ≥107 has the best specificity to predict outcome after clean intermittent catheterization training for people with multiple sclerosis. The sensitivity of the FIM and PP-Test is similar, and both have a large effect size for the outcome of self-catheterization training in multiple sclerosis.

INTRODUCTION: This study aimed to empirically validate a French version of the Neurogenic Bladder Symptoms Score-Short From (NBSS-SF), a psychometric multidimensional tool to assess lower urinary tract symptoms (LUTS) for patients with a neurological condition. METHODS: One hundred and five participants with multiple sclerosis or spinal cord injury prospectively completed the questionnaire at baseline and 7-14 days later. The α coefficient of Cronbach (internal consistency) and the intraclass correlation coefficient (ICC) (test-retest reliability) were calculated. RESULTS: The internal consistency for the overall questionnaire was high (Cronbach's α coefficients from 0.79), while coefficients for each subscale were variable (urinary incontinence 0.91; storage and voiding 0.69; consequences 0.25). For test-retest reliability, 88/105 (84%) patients filled and sent back their questionnaire 10 days (±3.6 days) after baseline version. ICC was 0.90 for the total score and was 0.73 for the urinary incontinence subdomain, 0.79 for storage and voiding, and 0.75 for consequences. CONCLUSIONS: The psychometric qualities of the French version of the NBSS-SF are well-supported, thus providing a valid tool to measure bladder symptoms across three different domains in patients with neurogenic bladder.
RESUMO
BACKGROUND/AIMS: External anal sphincter (EAS) plays an important role in fecal and gas voluntary continence. Like every muscle, it can be affected by repeated efforts due to fatigability (physiological response) and/or fatigue (pathological response). No standardized fatiguing protocol and measure method to assess EAS fatigability has existed. The aim is to test a simple, standardized protocol for fatiguing and measuring EAS fatigability and fatigue to understand better the part of EAS fatigability in the pathophysiology of fecal incontinence. METHODS: Patients with anorectal disorders evaluated with anorectal manometry were included. They had to perform 10 repetitions of maximum voluntary contraction (MVC) of 20 seconds. Measurement was made with an anorectal manometry catheter and a surface recording electromyography (EMG). The primary outcome was the difference in EMG root mean square between the first and the last MVC. Secondary outcomes were differences in other EMG and manometry parameters between the first and the last MVC. Difficulties and adverse effects were recorded. RESULTS: Nineteen patients underwent the fatiguing protocol. All patients completed the entire protocol and no complications were found. No difficulty was declared by the examiner. A significant decrease in root mean square was found between the first and last MVC (0.01020 ± 0.00834 mV vs 0.00661 ± 0.00587 mV; P = 0.002), in maximum anal pressure area under the curve of continuous recordings of anal pressure and mean and total EMG power (P < 0.05). CONCLUSIONS: This protocol is simple and minimally invasive to measure EAS fatigue and fatigability. We highlighted a fatigue of EAS in many patients with anorectal disorders.
