Prevalence of comorbidities in multiple sclerosis patients with neurogenic bladder.

AIMS: The aim of this study was to define the prevalence of comorbidities among multiple sclerosis patients with lower urinary tract symptoms. METHODS: A retrospective study of data collected prospectively from January 2000 to March 2016 was carried out using a database. Comorbidities were divided into several classes according to the International Classification of Diseases (ICD-10). RESULTS: One hundred and fifty-five patients were included. All had a neurogenic bladder with 150 (96%) overactive bladder. EDSS score was≥6 in 44 patients (28%). Comorbidities were present in 79 (50,9%) and the most frequent ones were cardiovascular (14,2%), endocrinological (10,3%), urological (8,4%), abdominal (7,7%). Overweight (BMI≥25) was observed in 63 (40%). A strict relationship was found for BMI and stress urinary incontinence (P<0.001) as well as voiding dysfunction (P=0.003) without significant association for BMI and overactive bladder. CONCLUSION: Prevalence of comorbidities is important in MS (more than 50%). A significant association is found between overweight, stress urinary incontinence and voiding dysfunction. Knowledge of these comorbidities in MS is important since the presence of these urinary symptoms not related to neurogenic bladder must lead to a specific treatment. LEVEL OF EVIDENCE: 3.

Short-term reproducibility of cystometry in multiple sclerosis patients.

OBJECTIVE: To assess the reproducibility of detrusor activity cystometric pattern in multiple sclerosis (MS) patients, which is poorly documented in the medical literature, by means of successive filling. METHODS: We conducted a prospective study in MS patients; cystometry was repeated twice at 5minutes of interval if a detrusor overactivity before 300mL of filling was observed. Thus, 3 successive cystometries were analysed. The following characteristics were recorded: detrusor maximum pressure (Pmax), volume at the first involuntary detrusor contraction (IDC), maximum cystometric capacity (MCC), pressure at the first IDC, the existence of an overactive detrusor classified as phasic or terminal. RESULTS: We included 31 patients (19 women and 12 men); only 6 patients were naïve-treatment, the mean EDSS was: 5.3 (±1.6) and the mean age was 48.4 (±12.5) years. All the patients had an overactive detrusor for each cystometry. The reproducibility was good for all the parameters (range ICC between 0.7 and 0.83). CONCLUSION: Quantitative and qualitative cystometric data have a good reproducibility in MS patients with detrusor overactivity before 300mL of filling. LEVEL OF PROOF: 3.

[Female orgasm during neurological disorders]. / L'orgasme féminin dans les pathologies neurologiques.

INTRODUCTION: Sexual dysfunctions, particularly orgasm dysfunction, were not routinely assessed in daily practice in neurological women. OBJECTIVE: To assess type, frequency and impact of neurological women orgasm dysfunction. METHOD: A systematic review was conducted with Medline via Pubmed and The Cochrane Database of Systematic Review. RESULTS: Neurological women's orgasm dysfunction is poorly assessed. The most of these were clinical small retrospective studies assessed by general questionnaires and some with electrophysiological assessments. Multiple sclerosis (MS) and Spinal cord injury (SCI) were the two most studied conditions. Orgasm dysfunction is observed in one third of neurological women, associated with arousal troubles, voiding and anal dysfunction. Orgasm alteration seriously impact quality of life of these patients. CONCLUSION: Specific studies could be conducted in this specific field in order to increase quality of life of these neurogenic patients suffered from such sexual dysfunction.

Effect of need to void on Parkinsonian gait.

AIMS: Beside motor control alteration and tremor, the main symptoms in Parkinsonian disorders, lower urinary tract dysfunction is very common and thus often associated with gait disorder. No studies have assessed their association yet. The aim of this study was to assess the effect of the need to void on walking speed in this particular population. The secondary aim was to assess the effect of desire to void in a double task condition on the walking speed, and on the time to raise up from the floor. METHODS: This prospective study included all Parkinsonian disorders who had a follow-up for overactive bladder (OAB). We invited them to drink until a desire to void or equivalent (DV), then they performed three ten-meters walk tests, one double-task ten-meters walk test, one timed-up-and-go test (TUG), one timed raise of the floor (GMT). We repeated the same tests just after bladder emptying. RESULTS: Nine men and two women (age 69±6) were included in the study (seven Parkinson's Diseases, two multisystem atrophies, two not yet characterized). Mean scores of UPDRS-III were 17±6.5, Hoehn & Yahr scale were 1.9±0.7, time since onset 7±4.4 years, levodopa daily equivalent 691±478mg. Patients performed the walking tests at DV with a mean bladder volume from 220±189mL. The mean speed was 1m/s at DV and 1.1m/s at PV (P<0.001). TUG was also increased for patients at DV: mean 9.8 s at DV versus 8.8sec at PV (P<0.003). CONCLUSION: In Parkinsonian disorders, need to void may impact the walking speed, a strong desire to void worsening gait velocity. LEVEL OF EVIDENCE: 4.

[Urinary tract symptoms in Lewy body dementia: About 19 cases]. / Les troubles urinaires de la maladie à corps de Lewy. À propos de 19 cas.

INTRODUCTION: Lewy Body Dementia (LBD) is a Parkinsonian disorder which often leads to Lower Urinary Tract Symptoms (LUTS), especially an Overactive Bladder (OAB). There have been few LBD related LUTS depictions in the literature, which is why we did this retrospective study. METHODS: Retrospective single institution study. RESULTS: Nineteen patients with confirmed LBD diagnosis were found, (63% of men, mean age 74 years old). The main symptom was OAB (100% of patients) with frequent stress urinary incontinence (94%) associated with detrusor overactivity (93%) with pressure elevation (79%). Voiding difficulties were found in 16% of medical interviews, and in 53% of urodynamics. In total, 92% of patients complained of constipation, with 44% suffering from fecal incontinence. DISCUSSION: LBD is characterized by alpha-synuclein aggregates in the cerebral cortex, thus explaining associated cognitive impairment. The most commonly found LUTS is stress incontinence. We also found voiding difficulties in smaller proportion, sometimes associated with prostatism. Topographically, these symptoms could be explained by alpha-synuclein aggregates in the frontal and temporal cortex and the pons. Anorectal disorder and sexual dysfunction were frequently associated. Urological complications are scarce in this population, screening is focused in increasing quality of life, and the possibility to discriminate the different types of Parkinsonisms. CONCLUSION: OAB is the most common lower urinary tract symptom in LBD often associated with detrusor overactivity, and less frequently voiding difficulties sometimes associated to prostatism.

Emptying cystometry: A feasibility and validation pilot study on female patients.

INTRODUCTION: To assess the feasibility and the accuracy of emptying cystometry in order to simplify the manometric follow-up of overactive detrusor in neurological patients under anticholinergic or botulinum toxin injections. MATERIAL: Female patients with a stable detrusor underwent both a conventional cystometry and sequential measurements of bladder pressure during emptying (emptying cystometry). At the end of the standard cystometry, a CH12 urinary catheter was introduced in the bladder and was connected to a three-way stopcock. The second way of the stopcock permitted the emptying. The third way of the stopcock was connected to a vertical graduated tube to measure the bladder pressure each 50mL during the bladder emptying. RESULTS: Eleven female patients were included (mean age: 59.4years). Nine patients (82%) had neurogenic bladder. Mean cystometric capacity was 439mL (SD: 35mL). During the emptying cystometry, 8 to 10 measures were taken (mean: 9.4). The mean detrusor pressure was 1.7cmH2O (SD 2.1) for the filling cystometry and 2.3cmH2O (SD: 2.7) for the emptying cystometry. The agreement between the detrusor pressure between the two cystometries was good with intra-class correlation coefficient at 0.66 [0.48-0.77] - and the correlation was high (r=0.7; P<0.000001). CONCLUSION: In a small, selected sample of patients, emptying cystometry provides similar results of detrusor pressure to filling cystometry. This technique could constitute a home monitoring of bladder pressures in a selected population of patients with intermittent catheterization in whom a manometric follow-up of detrusor overactivity is required.

[Self-intermittent-catheterization and urinary retentions in Parkinsonian syndromes]. / Auto-sondages intermittents et rétentions urinaires des syndromes parkinsoniens.

INTRODUCTION: Lower urinary tract symptoms are common in Parkinson diseases, especially chronic urinary retention. In case of significant and symptomatic postvoid residual, a specific treatment is necessary in order to empty the bladder and nowadays the gold standard of such neurogenic bladder is based on self-intermittent-catheterizations, if possible at all. We carried out a retrospective study about feasibility and outcomes of self-intermittent-catheterizations in this population. METHODS: Retrospective study with qualitative and quantitative, clinical and instrumental (urodynamic) assessment, of lower urinary tract symptoms as urinary retention in extrapyramidal syndromes. RESULTS: Overall, 42 patients with parkinsonian syndrome performing self-intermittent-catheterization were assessed. Twenty-one had idiopathic Parkinson's disease, 17 multiple system atrophy, 1 vascular Parkinson, 1 iatrogenic Parkinson and 2 not yet determined parkinsonian syndromes. All the patients had urinary retention characterized by a postvoiding residual volume more than 150mL. All the patients were symptomatic and reported voiding dysfunction (30/42), overactive bladder syndrome (20/42), stress urinary incontinence (6/42). The cystometry showed detrusor overactivity (15/42), bladder-sphincter dyssynergia (15/42), detrusor underactivity (14/42), sphincter deficiency (4/42) or bladder compliance alteration (3/42). Each patient have learned and well controlled self-intermittent-catheterization technique. Fourteen (33%) stopped self-intermittent-catheterization prematurely in the following months because of functional impact of neurological worsening. CONCLUSION: Even if one third of the patients had stopped self-intermittent-catheterization because of neurological deterioration, this technique remains the gold standard for the treatment of urinary chronic retention in parkinsonian patients.
