Relationship between desire to void and bladder capacity and rectal sensory function in patients with multiple sclerosis and anorectal disorders.

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.

Lower urinary tract symptoms treatment constraints assessment (LUTS-TCA): a new tool for a global evaluation of neurogenic bladder treatments.

OBJECTIVES: To develop a new tool to assess constraints due to urinary treatments in neurological patients. MATERIALS AND METHODS: A prospective, monocentric study has been conducted from January to May 2017. Out-patients (multiple sclerosis, spinal cord injury, Parkinson disease) were included in a referral center if they had LUTS treatment for at least 3 months. To validate psychometric properties, we conducted a literature review, qualitative interviews, and discussion with a panel of six experts. Comprehension, acceptation, and pertinence were tested by a pilot study. A validation study, designed to calculate content validity, internal consistency reliability, and test-retest reliability [intraclass correlation coefficient (ICC)] has been conducted. The primary outcome was good psychometric properties defined with Cronbach's α > 0.7 and ICC > 0.7. RESULTS: Comprehension, acceptation, and pertinence were excellent. Validation study showed a perfect content validity (r2 = 1) and excellent internal consistency reliability (Cronbach' α = 0.90). Total score was between 0 (best score) to 66 (maximal constraints). Test-retest reliability calculated using ICC was 0.81. Time to fill questionnaire was 4 min 20 s. The final version was composed by 22 items. CONCLUSION: LUTS TCA is the first validated tool to assess constraints of urinary treatment and has excellent psychometric properties.

Predictive factors of adherence to urinary self-catheterization in older adults.

AIMS: The primary aim is to explore the adherence predicting factors in clean intermittent self-catheterization (CISC) in patients aged over 65 years. The secondary aim is to assess whether in this population, the non-adherence risk is greater, compared with patients under 65. METHODS: All patients older than 65 that successfully learned CISC between January 2011 and January 2016 were included. A control population younger than 65 matched with sex, body mass index, and pathology was selected. RESULTS: One hundered and thirteen (66.9%) out of the 169 patients older than 65 included were adherent at 1 month, and 80 (47.3%) at 6-12 months. Obesity (P = 0.027), a low PP test (Pencil and Paper test) score (P = 0.037), significant urinary stress incontinence (SUI) (P = 0.048), and prescription of CISC less than three per day (P = 0.03) were the risk factors predicting stopping CISC at 1 month, but none was associated with non-adherence at 6-12 months. Compared with the younger group, age was a risk factor for poor adherence at 1 month. CONCLUSION: Obesity, low PP test score, and important SUI are factors of poor adherence to CISC at 1 month in older adults. Necessity of more than three CISC per day is in favor of treatment continuation, possibly due to absence of spontaneous voiding in these patients. Long-term adherence to CISC in older adults in this study remains close to adherence to other treatments prescribed in urinary disorders, and thus shows that CISC could be an easily purposed therapeutic option in this population, either on a long-term or transitory basis.

Influence of the urine stream interruption exercise on micturition.

OBJECTIVES: To assess the effect of urine stream interruption exercise on micturition. METHODS: This study was conducted prospectively in female patients without urinary disorders. Two uroflowmetries were performed: one during a usual micturition and one during an exercise of urine stream interruption. For the urine stream interruption exercise the subject was asked to begin the micturition, to stop it at 3 s, when the stream is interrupted, to start voiding again, then again stop it at 3 s and repeat this manoeuvre until the end of the micturition. RESULTS: Twenty female patients (mean age 38.7 years old, SD 12.3) were included. Post void residual volume was higher after the urine stream interruption micturition (mean 36.7 mL, SD 46.6) than during standard micturition (mean 8.2 mL, SD 24.1) (P = 0.02). During normal voiding, the maximal flow rate was higher (26.9 mL/min vs 17.8 mL/min; P < 0.0001). There was no difference concerning neither the voiding volume nor the slope of ascending part of flow curve. During urine stream interruption micturition, the flow rate slope, the voiding volume and the maximal flow rate by voiding sequence were decreasing as the voiding sequences followed each other. CONCLUSIONS: Urine stream interruption increases the post-void residual volume and translates into less efficient micturition. Thus, it should not be used in current practice of pelvic floor muscles training.

Urinary Disorders and Marfan Syndrome: A Series of 4 Cases.

Marfan syndrome is a genetic disease responsible for causing cardiovascular, eye and musculoskeletal damages. Urinary disorders are not common. We present 4 cases of chronic urinary tract symptoms, with 2 different pathophysiological processes. Three patients presented with spinal cord infarct following aortic dissection surgery. They were affected by an overactive bladder with detrusor overactivity and detrusor-sphincter dyssynergia. One patient complained of voiding dysfunction, possibly related to dural ectasia. Although a rare outcome, urinary disorders may appear in Marfan syndrome, by the occurrence of surgical complications in aortic surgery or possibility of sacral nerve root compression. If so, medical care is necessary to prevent uro-nephrological complications.

Influence of a distraction task on pelvic floor muscle contraction.

AIMS: Attention may play a key role in the contraction of pelvic floor muscles in stressful situations, meaning that mental distraction may be involved in urinary incontinence. METHODS: Informed consent was obtained from 20 healthy volunteers. The electromyographic (EMG) activity of the external anal sphincter (EAS) was recorded during voluntary contraction elicited by local stimulation. The trials were carried out twice: combined (or not) with a mental distraction task (PASAT), Paced auditory serial additional test. Reaction time, latency between the stimulus and maximum EAS EMG activity, duration of the contraction, maximum EAS EMG activity, and the area under the EAS EMG activity curve were measured. RESULTS: The mental distraction task led to a 3.98 times greater reaction time (RT), (P = 0.00001 Wilcoxon's test). The RT increased from 217 (IQR: 170-270) to 779 msec (IQR: 550-1,025, P < 0.0001) when the EAS contraction was combined with PASAT. However, the maximum EAS EMG activity was weaker during PASAT than in the absence of a mental distraction task: 0.0850 mv versus 0.0701 mv, that is, 1.21 times weaker (P = 0.00077, Wilcoxon's test). Finally, when the two conditions (respectively with and without the mental distraction task) were compared, no significant difference was found in the area under the EAS EMG activity curve (0.0157 mv sec vs. 0.0162 mv sec, ratio 1.01, P = 0.52). CONCLUSIONS: The mental distraction task altered voluntary contraction of the pelvic floor muscles.

Sexual Dysfunction Management and Expectations Assessment in Multiple Sclerosis-Female (SEA-MS-F): creation and validation of a specific questionnaire.

INTRODUCTION: Until now, no questionnaire has been developed to study specific expectations concerning sexual dysfunction management and the availability of information on sexuality in the female population affected by multiple sclerosis (MS). Understanding and meeting the patient's expectations is an issue of considerable importance in the evaluation of medical care. AIM AND MAIN OUTCOME MEASURE: We present the development and validation of a specific questionnaire designed for women with MS in order to assess their expectations in terms of sexual dysfunction management: the SEA-MS-F (Sexual Dysfunction Management and Expectations Assessment in Multiple Sclerosis-Female). METHODS: This questionnaire was created and validated by an expert panel, using the Delphi method. The psychometric evaluation was obtained with a sample of 40 female MS patients. Cronbach's alpha index and principal component analysis were used to measure the questionnaire's internal consistency. RESULTS: A consensus on the questionnaire was reached with the Delphi method. The SEA-MS-F is fully compliant with the criteria for psychometric validation among female MS patients, and its internal consistency is excellent (Cronbach's alpha 0.948). CONCLUSION: The SEA-MS-F appears to be a useful tool that could be used either in routine medical situations or in prospective studies of MS in order to ascertain women's expectations concerning the management of their sexual dysfunction.

Need to void and attentional process interrelationships.

OBJECTIVES: To determine whether a strong urge to void could affect a person's attentional performance. To determine whether an attentional task could decrease a strong urge to void a prospective study was performed. SUBJECTS AND METHODS: Healthy adults were asked to perform two neuropsychological tests, the modified Paced Auditory Serial Addition Test (mPASAT) and the Psychology Experiment Building Language Continuous Performance Test (pCPT), under two different conditions: no need to void, and a strong urge to void defined by a score of >70/100 mm on a visual analogue scale. RESULTS: In all, 21 healthy volunteers were included. There was no statistical difference between the mPASAT scores from the two sessions (P = 0.57). The mean total error score of the pCPT increased with the individual's urge to void (P = 0.043). The mean omission score decreased, but was not statistically different (P = 0.129), the commission error score increased with the urge to void (P = 0.017), with a shorter reaction time for the inter-stimuli intervals of 1 (P<0.001) and 2 s (P = 0.036), suggesting a tendency to hurry. CONCLUSIONS: A strong urge to void can alter attentional performance, with a tendency to hurry, in healthy volunteers taking part in a sustained attention test pCPT involving the use of the anterior cingulate cortex.

Posterior vaginal wall pull down maneuver: a clinical test to diagnose intrinsic sphincter deficiency in women suffering from genuine urinary stress incontinence.

OBJECTIVES: To assess the predictive value of a simple clinical test (posterior vaginal wall pull down maneuver) in the diagnosis of intrinsic sphincter deficiency. METHODS: The present prospective study included 62 women suffering from stress urinary incontinence. Every patient underwent a urogynecological examination including multichannel urodynamic testing (cystometry, urethral pressure profile, Valsalva Leak Point Pressure measurement) and a clinical examination including posterior vaginal wall pull down maneuver. Posterior vaginal wall pull down maneuver was carried out with the bladder filled with 400 mL of saline in a supine position, and was obtained by means of a split speculum allowing gentle pull down traction of the posterior vaginal wall. Posterior vaginal wall pull down maneuver was considered as positive when a urine leak was observed during the manoeuvre. Intrinsic sphincter deficiency was urodynamically defined by maximum urethral closure pressure ≤20 cmH2 O. Correlations between positive/negative posterior vaginal wall pull down maneuver and urodynamic intrinsic sphincter deficiency were calculated. RESULTS: There was a statistical correlation between age and low maximum urethral closure pressure (P < 0.0001), and between low maximum urethral closure pressure and positive posterior vaginal wall pull down maneuver (P < 0.0001). Regarding the intrinsic sphincter deficiency diagnosis, the posterior vaginal wall pull down maneuver positive predictive value was 94.67% and the negative predictive value was 95.4%, with a specificity of 97.6% and sensitivity of 90%. CONCLUSION: Posterior vaginal wall pull down maneuver is a reliable clinical test, easy to carry out, inexpensive and without significant risk. This test allows the diagnosis of intrinsic sphincter deficiency in women suffering from stress urinary incontinence, thus avoiding further invasive urodynamic testing (urethral pressure profile, Valsalva Leak Point Pressure measurement) in women with genuine stress urinary incontinence. Furthermore, it is helpful when choosing the type of sling procedure (retropubic vs transobturator) when a surgery is planned.

Pencil and paper test: a new tool to predict the ability of neurological patients to practice clean intermittent self-catheterization.

PURPOSE: We created and validated the new pencil and paper test, which allows assessment of the ability of patients with a neurological disorder to practice clean intermittent self-catheterization. MATERIALS AND METHODS: We developed a simple test including common gestures mimicking the usual maneuvers needed during clean intermittent self-catheterization, and involving the same cognitive and physical resources needed for this technique. We evaluated the test in 118 patients with a neurological condition. Instruments needed to perform the pencil and paper test are limited to a sheet of paper and a pencil. Each test item was quantified and graded with a total score of 15. A specific clean intermittent catheterization learning scale was used to classify the outcome of the ability to perform clean intermittent self-catheterization with a score range of 5--learning easy and self-catheterization complete to 0--learning impossible. RESULTS: Enrolled in the study were 118 patients with a neurological condition. There was strong correlation between the global pencil and paper test score, and the ability to perform clean intermittent self-catheterization, as evaluated by the learning scale (r = 0.82, p = 0.000091). At a test cutoff of 10 and a clean intermittent self-catheterization cutoff of 3, which was the limit needed to practice self-catheterization alone, the positive predictive value of the pencil and paper test was 85% and its negative predictive value was 94% (Cronbach's α = 0.88). CONCLUSIONS: The pencil and paper test is a valid way to predict the ability to practice clean intermittent self-catheterization in patients with a neurological disorder.

Qualitative and quantitative analysis of rectoanal inhibitory reflex (RAIR) modulation in functional bowel disorders.

BACKGROUND: Rectoanal inhibitory reflex (RAIR) is a physiological reflex implicated in anorectal continence. A lack of RAIR modulation is only described in spinal cord-injured patients with a lesion under L2. No quantitative data has been published concerning the normal modulation in amplitude and in duration in functional disorders. METHODS: A retrospective analysis of anorectal manometry, performed in 40 safe-neurological patients, suffering from idiopathic constipation and/or faecal incontinence, has been done. RAIR were obtained by five successive rectal distensions (10-50 ml).Resting pressure, residual pressure, percentages of relaxation, slope and duration of inhibition were estimated. Four hypotheses of normal modulation in amplitude and duration were set up using these parameters. The cut-off values chosen for the hypotheses were similar to results obtained by calculating median value +/- 2SD of the parameters. RESULTS: All the 40 patients had present RAIR. Concerning the modulation of RAIR, we tested the hypotheses with the aim of finding those applying to patient's largest number. Amplitude: 85% of the patients had a normal modulation defined by a difference >8 cm H2O between two non-consecutive residual pressure on three successive rectal distensions. DURATION: 77.5% of the patients had a normal modulation defined by a time difference >2 s between two non-consecutive durations on three successive rectal distensions. CONCLUSION: Determination of normal values of RAIR modulation in functional disorders is interesting in clinical practise, suggesting that the patients with a lack of normal RAIR modulation (in amplitude or in duration) may have a neurological disease.

Modulation of the rectoanal inhibitory reflex (RAIR): qualitative and quantitative evaluation in multiple sclerosis.

BACKGROUND: Rectoanal inhibitory reflex (RAIR) is a physiological modulated reflex involved in anorectal continence and defined by a relaxation of internal anal sphincter following rectal distension. Its existence depends on intramural autonomic ganglions and its modulation on the integrity of the autonomic nervous system (ANS). AIMS: The aim of this study was to analyse RAIR modulation in terms of amplitude and duration in multiple sclerosis (MS) patients. METHODS: Twenty-one patients with MS and 40 control patients had anorectal manometry. Qualitative assessment (presence or absence) of RAIR was evaluated together with its modulation in amplitude and in duration. RESULTS: All patients had present RAIR for each volume of rectal distension (10-50 ml). Seven patients (33.3%) in the MS group had abnormal RAIR modulation in amplitude (odds ratio (OR) = 2.78, compared to control group, p = 0.11). Nine patients (42.9%) in the MS group had abnormal RAIR modulation in duration (p = 0.14, OR = 2.54, compared to control group). Alteration of RAIR modulation was not correlated with Expanded Disability Status Scale, faecal incontinence and constipation (p > 0.05). Course of MS (relapsing-remitting MS or secondary progressive form) seems to be correlated to alteration of modulation in amplitude and in duration (OR = 1.31 and 1.07). CONCLUSION: Even if our results do not have the required statistical significance (p > 0.05), they are interesting. If RAIR is always present in MS, its modulation seems to be altered. A hypothesis for this lack of RAIR modulation could be the alteration of ANS, often involved in MS besides somatic nervous system lesions.

Assessment of sacral spinal excitability using stimulus-response curves of the bulbocavernosus reflex.

OBJECTIVE: To analyze and quantify sacral spinal excitability through bulbocavernosus reflex (BCR) stimulus-response curves. METHODS: Thirty subjects with upper motor neuron lesions (UMN) and nine controls were included in this prospective, monocentric study. Sacral spinal excitability was assessed using stimulus-response curves of the BCR, modeled at different bladder filling volumes relative to the desire to void (as defined by the International Continence Society) during a cystometry. Variations in α (i.e. the slope of the stimulus-response curve) were considered as an indicator of the modulation of sacral spinal excitability. RESULTS: In all subjects, α increased during bladder filling suggesting the modulation of spinal sacral excitability during the filling phase. This increase was over 30% in 96.7% of neurological subjects and 88.9% of controls. The increase was higher before the first sensation to void in the neurological population (163.15%), compared to controls, (29.91%), p < 0.001. CONCLUSIONS: We showed the possibility of using BCR stimulus-response curves to characterize sacral spinal response with an amplification of this response during bladder filling as well as a difference in this response amplification in patients with UMN in comparison with a control group. SIGNIFICANCE: BCR, through stimulus-response curves, might be an indicator of pelvic-perineal exaggerated reflex response and possibly a tool for evaluating treatment effectiveness.

External Anal Sphincter Fatigability: An Electromyographic and Manometric Study in Patients With Anorectal Disorders.

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.

Effect of a strong desire to void on walking speed in individuals with multiple sclerosis and urinary disorders.

BACKGROUND: Lower urinary tract symptoms, especially overactive bladder, are frequent and disabling in individuals with multiple sclerosis (IwMS). An association with gait disorders is common, which could aggravate continence difficulties and affect quality of life. The association between the need to void and walking has never been studied in this population. OBJECTIVE: The primary aim of this study was to assess the effect of a strong desire to void (SDV) on walking speed in IwMS and lower urinary tract symptoms. The secondary aim was to identify clinical or urodynamic factors associated with walking speed impairment at SDV in this population. METHODS: We included IwMS with urinary disorders and Expanded Disability Status Scale score<7 in this observational study. Individuals underwent 3 10-m walk tests (10MWT) and one Timed Up and Go (TUG) test at SDV and at post-void (PV). RESULTS: Among the 72 IwMS included (mean [SD] age 50.6 [11.6] years; 46 [64%] females), the mean (SD) speed for 10MWT was 1.00 (0.31) m.s-1 at SDV and 1.07 (0.30) m.s-1 at PV (P<0.0001). Time for TUG was also increased when individuals felt SDV: mean 11.53 (4.6) sec at SDV versus 10.77 (3.8) sec at PV (P=0.004). No predictors of greater impairment of walking speed at SDV were identified. CONCLUSION: This study suggests a clinical impact of bladder sensation on walking speed in IwMS and urinary disorders. None of the individual characteristics could predict greater decrease in gait velocity at SDV.

Lumbosacral radicular pain during micturition, defecation or orgasm.

BACKGROUND: The objective of this study was to describe, in a cohort of patients followed for bladder, bowel or sexual dysfunctions, the occurrence of radicular pain during micturition, defecation and/or orgasm. METHODS: The study included all patients referred in our neuro-urology department and who suffered from radicular pain before, during or after micturition, defecation and/or orgasm. Data included demographic and medical variables, urodynamic and perineal electromyographic diagnosis. RESULTS: A total of 30 patients (men: 70%, mean age 45.4 ± 11.8,) complained of radicular pain before, during or after orgasm (51.4%), micturition (34.3%), or defecation (14.3%). In 30% of cases, radiculopathy was found and was predicted by micturition pain. Other pathologies were as follows: vertebral (16.5%), pelvis and sacral (16.5%), inflammatory central nervous system (10%) lesions and peripheral neuropathies (6.7%). Neurological level of injury was between the lumbar and the sacral level. All spinal cord lesions were lesions of the conus medullaris. Patients also complained of lower urinary tract symptoms (70%), sexual (63.3%) and bowel (60%) disorders. In most cases, the urodynamic diagnosis was neurogenic bladder with peripheral abnormalities and the electromyographic diagnosis was distal neuropathy. CONCLUSION: Radicular pain occurring during micturition, defecation or orgasm is a rare condition. The most common underlying lesion seems to be radiculopathy, from lumbar to sacral spine. The presence of these symptoms, in the absence of any known neurological condition, should suggest the practitioner a radiculopathy in most of the cases. In consequence, appropriate additional tests should be offered to these patients. SIGNIFICANCE: Few data are available on sciatica during micturition, defecation or orgasm. This study underlines the need for appropriate tests if a patient complaint from this type of symptom. Indeed, the most common underlying lesion is a radiculopathy but can also be a lesion of conus medullaris.

Use of a specific questionnaire and perineal electromyography to assess neuropathic pain after radical retropubic prostatectomy.

OBJECTIVE: Prostate cancer is the most frequent cancer in men and radical retropubic prostatectomy (RRP) is one of the first-line treatment. However, RRP has some side effects and can lead to chronic perineal pain. The objective of the study was to determine in patients suffering from perineal pain after RRP the possibility of a neurogenic damage by means of a specific questionnaire dedicated to track down neuropathic pain. METHODS: Forty patients were explored by a specific and validated questionnaire, the Neuropathic Pain Symptom Inventory (NPSI). Patients were divided into two groups: Group A with an NSPI score ≥4 was considered as suffering from neuropathic pain, and Group B was considered as a control group without neuropathic pain (NSPI score <4). All patients had a perineal electrophysiological testing to confirm the possibility of a neurogenic damage. RESULTS: Group A was composed by 13 men and Group B by 27 men, with mean age 72.45 years and mean duration of pain 2.7 years. In Group A, the most frequent symptoms were burning sensation, electrical shock and numbness. Location of the pain was global perineal area (8/13), anus (10/13), penis (5/13) and glans penis (2/13). Electromyography (EMG) findings confirmed the presence of denervation and neurogenic damages compared with controls (p < 0.001). CONCLUSION: One third of the patients consulting for chronic pain following RRP had probably a neuropathic lesion leading to a chronic perineal pain as suggested by an NSPI score ≥ 4 and EMG alterations.

Specificity of Lower Urinary Tract Symptoms in Neuromyelitis Optica in Comparison With Multiple Sclerosis Patients.

PURPOSE: The aim of this study was to describe lower urinary tract symptoms in neuromyelitis optica (NMO), and to compare these data with urinary disorders observed in multiple sclerosis (MS) patients. METHODS: Retrospective study of data collected from January 1997 to July 2017 using the database from a Neuro-Urology Department of a university hospital. NMO and MS patients were matched for sex, age, and Expanded Disability Status Scale (EDSS). RESULTS: Twenty-six patients with NMO were included and compared with 33 MS patients. Mean age was 41.6 years (standard deviation [SD], 14,8), mostly female patients (24 vs. 2 males). Mean EDSS was 4.6 (SD, 1.8) in the 2 groups. In NMO group, 57% of the patients (n=15) had overactive bladder with urgency and urge incontinence and 38.5% (n=10) of them had nocturia. Voiding symptoms was observed in 69.2% of the patients (n=18); 42.3% of NMO patients performed self-intermittent catheterization versus 12.1% in MS patients (P=0.012). Low bladder compliance and severe urinary tract infections (pyelonephritis) were more frequent in NMO than in MS patients (respectively 15% vs. 0%, P=0.016 and 42% vs. 12%, P=0.024). CONCLUSION: Lower urinary tract symptoms, especially overactive bladder and urinary retention, are frequent in NMO. Low bladder compliance, serious urinary infections, and high prevalence of urinary retention requiring self-intermittent catheterization are the main symptoms significantly more frequent than in MS.

Intermittent Self-catheterization in Older Adults: Predictors of Success for Technique Learning.

PURPOSE: The main goal of this retrospective study is to explore the predictors of success in learning clean intermittent self-catheterization (CISC) in patients over 65 years of age. The secondary goal is to assess whether in this population, the risk of failure to perform CISC is greater, compared with patients under 65 with similar pathologies. METHODS: All patients older than 65 consulting between January 2011 and January 2016 for learning CISC were included. A control population younger than 65 matching with sex, body mass index, and pathology was selected. RESULTS: One hundred sixty-nine of the 202 patients (83.7%) over 65 succeeded in learning CISC. Obesity (P<0.05), low pencil and paper test (PP test) (P<0.01) and low functional independence measure (FIM) (P<0.01) scores were risk factors of failure. No significant differences were found with sex or pathology. In multivariate analysis, low PP test perineum access (odds ratio [95% confidence interval], 2.30 [1.32-4.42]), low FIM motor (1.04 [1.01-1.08]), and FIM cognition (1.18 [1.03-1.37]) scores were independent factors of learning failure. Compared to control group, age over 65 was not predictive of failure (P=0.15). CONCLUSIONS: Our study shows that success in learning CISC does not depend on age but on difficulties in mobility, access to perineum and probably cognitive disorders.

Lower Urinary Tract Symptoms in Elderly Population With Multiple Sclerosis.

PURPOSE: The aim of this study is to compare the clinical and urodynamic characteristics of urinary disorders in multiple sclerosis (MS) patients in a geriatric population with a nongeriatric population. METHODS: This study was conducted retrospectively between 2010 and 2016. Each patient with MS aged 65 and older was matched with 2 patients with MS aged less than 65 in sex, form of MS, and Expended Disability Status Scale (EDSS). Demographic data, urinary symptoms, treatment, quality of life, repercussion of lower urinary tract symptoms on daily life activities and psychological state and urodynamic parameters were collected. Differences between the 2 populations were evaluated using Student test, chi-square, or Fischer tests. RESULTS: Twenty-four patients with MS aged 65 and older (mean age, 69.8 years) were matched with 48 patients aged less than 65 years (mean age, 49.4 years). Maximum urethral closure pressure was lower in the elderly population than in the nongeriatric population (mean±standard deviation [SD]: 35.6±18.5 cm H2O vs. 78.2±52.3 cm H2O, P<0.001). In the male population, there was no statistical difference in any other clinical or urodynamic endpoints. In the female population, voiding symptoms was more described in the nongeriatric population (Urinary Symptom Profile low stream: 3.4±3.5 vs. 1.7±2.4, P=0.04), geriatric population had less urinary treatment (P=0.05). LUTS had less impact on quality of life (Qualiveen: 1.4±1.0 vs. 2.1±0.9, P=0.02) on the geriatric population than in the nongeriatric of female MS patients. CONCLUSIONS: Geriatric population of MS has few differences of urinary disorders compared to a nongeriatric population with EDSS, sex, and MS form equal. However, the psychological impact of these urinary disorders is less important in female geriatric population.
