Adherence to transanal irrigation in older adults: first-year assessment.

BACKGROUND: While the prevalence of chronic constipation and fecal incontinence increases with age, few data on transanal irrigation in older adults are available. The aim of this study was to assess the adherence and predictive factors for adherence to transanal irrigation during the first year of use in older adults. METHODS: This retrospective study included all patients over 65 years old, who had therapeutic education for transanal irrigation with the Peristeen® device between January 2010 and July 2019 in a neuro-urology department of a university hospital in France. The adherence rate was assessed at 1, 3, 6, and 12 months. Predictive factors for adherence were looked for by comparing persistent population and non-persistent population at 1, 3, 6, and 12 months. RESULTS: Sixty-nine patients over 65 years old were included. The adherence rate was 73.9% at 1 month, 55.1% at 3 months, 46.4% at 6 months, and 40.1% at 1 year. No predictive factor for adherence to transanal irrigation was identified. CONCLUSIONS: Adherence to transanal irrigation during the first year in older adults remains close to that in the adult general population. Predictive factors of adherence remain unclear.

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.

Verbal instruction to obtain voluntary pelvic floor muscle contraction: Acceptability, and understanding.

PURPOSE: The aim of this study was to describe verbal instructions used to obtain a voluntary pelvic floor muscle contraction and to evaluate their understanding and acceptability. METHODS: This prospective study led in two phases. A questionnaire was submitted to experts to collect the most frequently used instructions to obtain a PFMC. Then a questionnaire was submitted to subjects in order to: estimate the pelvic floor anatomical knowledge; estimate understanding and acceptability of these instructions; select the best instruction. RESULTS: First phase: 46 experts proposed 356 instructions. Forty-four percent were functional instructions ("hold a gas"), 40% anatomical ("squeeze your anus") and 16% allied both. Fifteen instructions for the women and 11 for the men were selected. Second phase: 33 subjects completed the questionnaire. More than 75% had correct answers for anatomical knowledge. The instructions judged by the subjects as the most adapted to obtain a PFMC were: "contract the anus", "do as if you wanted to hold a strong desire to void". The items including "perineum" or "vagina" were less understood. CONCLUSIONS: The more understandable and acceptable instruction to assess the PFMC is the association of two simple instructions: one anatomical and one functional. LEVEL OF EVIDENCE: 4.

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.

Pregnancy and Delivery in Women with Lower Urinary Tract Reconstruction: A National Multicenter Retrospective Study from the French-Speaking Neuro-Urology Study Group (GENULF) and the Neuro-Urology Committee of the French Association of Urology.

PURPOSE: Management of pregnancy and delivery in women with lower urinary tract reconstruction is challenging and the currently available literature is insufficient to guide clinical practice. We report pregnancy and delivery outcomes in this specific population. MATERIALS AND METHODS: We conducted a national multicenter retrospective study (16 centers) including 68 women with 96 deliveries between 1998 and 2019. These women had at least 1 successful pregnancy and delivery after augmentation enterocystoplasty, catheterizable channel creation and/or artificial urinary sphincter implantation. Maternal and fetal complications during pregnancy and delivery were reported, as well as postpartum functional outcomes, according to the delivery mode. The chi-square test and Student's t-test were used to compare categorical and continuous variables, respectively. RESULTS: Overall 32% of reported pregnancies were complicated by febrile urinary tract infections, 13.5% by renal colic and 14.6% required upper urinary tract diversion. In addition, 10% of patients reported transient self-catheterization difficulties and 13.5% reported de novo or increased urinary incontinence. The preterm delivery rate was 35.3%. Elective C-section was performed in 61% of pregnancies. Twenty complications occurred during delivery (20%), including 19 during elective C-section. Urinary continence at 1 year was unchanged for 93.5% of deliveries. Delivery mode (p=0.293) and multiparity (p=0.572) had no impact on urinary continence. CONCLUSIONS: In this population C-section appeared to be associated with a high risk of complications. In the absence of any obstetric or neurological contraindications, vaginal delivery should be proposed as the first line option to the majority of these women.

[Concepts and assessment methods in lower urinary tract symptoms: From symptom score to Patient-Reported Outcomes and Outcomes (PRO)]. / Concepts et méthodes d'évaluation en pelvi périnéologie : du score de symptômes aux attentes et résultats rapportés par les patients (PRO).

INTRODUCTION: The evaluation of pelvic perineal treatments has changed significantly in recent years. Initially focused on the assessment of symptoms, quality of life or patient satisfaction, it has gradually turned to new concepts, such as Patient Reported Outcome (PRO) and Goal Attainment (GA). OBJECTIVE: To describe the different concepts and methods of assessment available, in recent years, in the context of urinary functional pathologies such as bladder overactivity or urinary incontinence. METHODS: We conducted a non-systematic literature review to identify the main questionnaires and tools available to evaluate treatment outcomes. Oncology and pediatrics questionnaire has been excluded. RESULTS: In functional pathology (overactive bladder or incontinence), the objective of treatment is to meet the expectations of patients and it is important to be able to assess the feelings of patients. In this context, new specific questionnaires have been developed to evaluate the PROs. For about ten years, these subjective criteria, are more and more widespread in the evaluation of treatments. A new field then appeared, namely Goal Attainment Scaling (GAS) and Self Appreciation Goal Attainment (SAGA), allowing to determine with the patient, the expected objectives of the treatment. CONCLUSION: These concepts of PRO and GAS open up a new domain in the evaluation of treatments, with a subjective view of the results. They deserve to be integrated into the usual, objective evaluations, in order to adapt the treatment of the patients, according to the real impact of the treatment.

[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.

How to dress up in Neuro-urology department?

INTRODUCTION: To examine patient preferences and perceptions regarding physician dress code in a neuro-urology department. MATERIAL: A questionnaire presenting with different physician dress codes was submitted to patients in a neuro-urology department: casual outfit with white coat, scrubs and scrubs with white coat. Respondents selected their ideal dress code and mentioned if any dress code shock them. Respondents' general opinions regarding physician attire, its importance and relation with patient satisfaction were collected. RESULTS: 163 questionnaires were completed. The three physician attires were chosen equally by the respondents. 71.4% of the respondents felt comfortable with the three attires. When an attire appeared to be offending, the casual attire with white coat was mentioned in 68.2%. 52.5% of the patients reported that the way their doctor dressed was important to them. 36.3% of respondents reported that physician attire influenced how confident they felt about the care they received. Male respondents preferred scrubs with white coat (44.0%) while female respondents preferred casual attire with white coat (42.0%), P=0.02. Neither the age, nor the reason of the consult, the knowledge of the department, the presence of neurological disease, the occupational category and the education level of the patient had an influence on the preference for one specific physician attire. CONCLUSION: Physician attire in neuro-urology may influence the way that patients perceive care. Physicians must not be restricted to one particular attire in neuro-urology department. However since almost 20% of the patients feel uncomfortable with the casual attire and white coat, it should be avoided. LEVEL OF EVIDENCE: 4.

[Impact of body mass index on lower urinary tract disorders in multiple sclerosis]. / Influence de l'indice de masse corporelle sur les troubles urinaires de la sclérose en plaques.

INTRODUCTION: Lower urinary tract symptoms (LUTS), and principally overactive bladder, are common in multiple sclerosis (MS). However, their origin is not necessarily unique. Obesity is widely recognized as a risk factor for stress urinary incontinence (SUI) and overactive bladder (OAB) in the general population. We wanted to evaluate the influence of body mass index (BMI) on LUTS in the MS population. MATERIALS AND METHODS: We conducted an uncontrolled monocentric retrospective study in 260 subjects classified into 4 BMI groups: underweight, normal weight, overweight, obese people. Comparisons by Mann-Whitney test were made between different BMI groups, in the overall population and then by gender. LUTS (SUI, OAB, BOO (bladder outlet obstruction) were assessed using USP questionnaire. RESULTS: In women, the mean OAB score was higher for obese women, 10.27 (SD=4.5) than for normal weight women, 7.96 (SD=4.58), P=0.024. The SUI score was lower for normal weight, 1.69 (SD=2.38) than for overweight, 3.19 (SD=2.91), P=0.002 and obese subjects, 3.80 (SD=3.23), P=0.0005. As in the overall population, the BOO score was higher in subjects with normal weight, 4.09 (SD=3.33) than in subjects with overweight, 1.91 (SD=2.03), P=0.0003 and in obese subjects, 2.33 (SD=2.37), P=0.013. The same comparisons in men were not significant. CONCLUSION: In this series, increased BMI was associated with higher OAB and SUI USP questionnaire scores, in women presenting with MS.

[Vaginal gas: Review]. / Gaz vaginaux : revue de la littérature.

OBJECTIVE: The aim of this article was to review the literature about vaginal winds (VW). METHODS: A literature review (Medline database, Cochrane Library and Google scholar) with no time limit was performed using keywords "vaginal winds", "vaginal noise", "vaginal gaz", "flatus vaginalis", "vaginal flatus", "colpophony", "Garrulitas vulvae", "vaginal laxity". RESULTS: From 412 articles about VW, 15 have been selected and 99 from 110 about vaginal laxity. VW occurs during physical exercises but also during and just after coïtus. The prevalence is about 20%. The pathophyiology of VW is probably a vaginal hyperlaxity itself secondary to pelvic floor muscles weakness and thus increased diameter of vaginal hiatus. VW alter sexual function in female patients but this sexual function seems not influenced in male partners. Tampons or pessaries are currently the most commonly proposed treatment (but naturally impossible to use during sexual intercourse), but some results from vaginal laser therapy are encouraging. CONCLUSION: Data from the literature suggest that vaginal winds are frequent and seriously impact quality of life of female patients. Childbirth and more generally vaginal laxity are the main causes. Pelvic-floor exercises, tampons, pessaries, surgery and laser can be proposed in order to improve sexual function in patients seeking treatment.

[Urethral pain during clean intermittent self catheterization: Retrospective analysis of 77 patients]. / Analyse de la douleur urétrale lors de la pratique de l'autosondage : étude rétrospective sur 77 patients.

OBJECTIVE: Clean self-intermittent catheterization (CIC) is the gold standard of the therapeutic approach of chronic urinary retention. Usually, CIC are safe, effective but in some cases catheterization can determine urethral pain during catheter insertion or withdrawal leading to poor adherence and compliance. To determine prevalence of pain during CIC and verify its impact on adherence to treatment. METHOD: Retrospective study with evaluation of pain during CIC one month following CIC teaching session by means specific and validated questionnaires: ICDQ (Intermittent Catheterization Difficulties Questionnaire), InCasaq (Intermittent Catheterization Satisfaction Questionnaire), I-CAS (Intermittent Catheterization Adherence Scale). RESULTS: Seventy-seven patients were recruited and 28 (36%) described pain during CIC. There is a strong relationship between pain and poor adherence (P<0.01). Female patients had a higher risk of urethral pain during CIC and in contrary BMI>25kg/m2 seems to be a protective factor of pain. CONCLUSION: In this series, urethral pain was associated with low compliance and adherence to CIC. 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.

[Use of botulinum toxin A in pelvic floor dysfunctions in the elderly: A review]. / Intérêt de la toxine botulinique A dans le traitement des troubles pelvi-périnéaux de la personne âgée.

INTRODUCTION: The present article is the final report of a multi-disciplinary meeting supported by the GRAPPPA (group for research applied to pelvic floor dysfunctions in the elderly). The objective was to conduct a comprehensive review on the role of botulinum toxin A (BonTA) in the treatment of pelvic floor dysfunctions in the elderly. METHODS: The present article, written as a comprehensive review of the literature, combines data issued from the scientific literature with expert's opinions. Review of the literature was performed using the online bibliographic database MedLine (National Library of Medicine). Regarding intra-detrusor BonTA injections, only articles focusing on elderly patients (>65 yo) were included. Regarding other localizations, given the limited number of data, all articles reporting outcomes of BonTA were included, regardless of studies population age. In case of missing or insufficient data, expert's opinions were formulated. RESULTS: Although, available data are lacking in this specific population, it appears that BonTA could be used in the non-fraily elderly patients to treat overactive bladder or even neurogenic detrusor overactivity, with a success rate comparable to younger population at 3 months (88.9% vs. 91.2%), 6 months (49.4% vs. 52.1%) and 12 months (23.1% vs. 22.3%), as well as a significant decrease in number of voids per day (11.4 vs. 5.29 P<0.001) and in the number of pads per day (4.0 vs. 1.3, P<0.01). Furthermore, BonTA is likely to be offered in the future as a treatment of fecal incontinence and obstructed defecation syndrome symptoms. Concerning bladder outlet obstruction/voiding dysfunction symptoms, intra-urethral sphincter BonTA should not be recommended. CONCLUSION: BonTA injections are of interest in the management of various pelvic floor dysfunctions in the elderly, and its various applications should be better evaluated in this specific population in order to further determine its safety and efficacy.

[Absorbent products for urinary incontinence management]. / Place des protections dans la prise en charge de l'incontinence urinaire.

INTRODUCTION: Despite therapeutic strategies of female and male urinary incontinence (UI) are currently well defined, there is no precise indication of the real place or strategy use of absorbent products regardless of the etiology of the incontinence or the clinical context. METHODS: We performed a research from the PubMed database using the following keywords: (urinary incontinence [MESH Terms]) AND absorbent pad [MeSH Terms]; allowing us to isolate 362 articles. RESULTS: Many protections designs are available over-the-counter without prescription and without reimbursement in France. For "light UI", disposable insert pads are the design that seems to be the most suitable for women, compared to disposable menstrual pads, OR=0.27 [0.14, 0.52], washable pants with integral pad OR=0.12 [0.06, 0.26] or washable insert pads OR=0.05 [0.02, 0.26]. For moderate to severe UI, there is no "best universal product". There are differences between the gender and the use of a panel of protections seems the most appropriate. Both women and men prefer pull-ups to disposable insert pads, OR=0.41 [0.20, 0.87] and OR=0.39 [0.22, 0.68] respectively. In men, a preference in 70 % of subjects for urisheats is observed compared to the protections they usually use (P=0.02). The use of protections improves independence in daily OR activities=0.102 [0.046, 0.158] and quality of life related to UI OR=4.40 [1.74, 7.07] compared to patients not using protections. Despite this, their use must remain cautious because of the potential infectious urinary complications, more frequent in particular in institutional people, with 41 % of users developing at least one urinary infection over an evaluation period of 12 months vs. 11 % of non-users (P=0.001), or immuno-allergic with the "dermatitis associated incontinence" whose prevalence can reach a rate of 50 %. CONCLUSION: Comparative analyzes of risk-benefit, economic costs, patient satisfaction, protections vs. other measures are lacking. It is necessary to continue the development of these products and to compare more precisely their intrinsic characteristics, to best support patients choices.

[Coital incontinence]. / L'incontinence coïtale.

INTRODUCTION: Urinary incontinence may seriously impact quality of life, self-image and subsequently the sexual life. Beside this fact, urinary leakage can specifically occur during sexual intercourse, formally named coital incontinence, and thus lead to specific alteration of the sexual life. AIM: To analyse the prevalence, pathophysiological mechanisms and possible therapeutic options for coital urinary incontinence. METHODS: Related terms to urinary incontinence and sexual dysfunction were search on PubMed database. RESULTS: Whereas at least a quarter of incontinent women have a coital incontinence, this symptom was rarely spontaneously reported. Some women had only coital incontinence (7.6 to 20% of cases). In men, urinary incontinence during sexual intercourse was mainly observed after prostatectomy in 20 to 64% of cases. Coital incontinence requires precise assessment. Indeed, it can occur whatever the phase of coitus: local stimulation (20-30%), excitement (13-18%), penetration (62.9-68%), movements back and forth, orgasm (27-37.1%). Cervico-urethral hypermobility, sphincter incompetence, urethral instability, detrusor overactivity could be the principal physiopathological mechanisms. In men, the main cause was a stress incontinence secondary to sphincter deficiency. Specific therapeutic strategies have proved their effectiveness. The rehabilitative approach (RR=0.25, CI [0.06-1.01]), medicinal (anticholinergic were effective in 59% of cases) or surgical therapeutic (slings with an efficiency of 87%) was proposed to patients. CONCLUSION: Coital incontinence is a common and troublesome symptom. Its precise assessment may suggest a specific mechanism and thus a specific treatment.

[Menthol in the control of bladder activity: A review]. / Le menthol dans le contrôle de l'activité de la vessie : revue de littérature.

INTRODUCTION: Menthol is a natural compound, of which the known effects on human physiology are manifold (a feeling of freshness, decongestant, bowel antispasmodic). Its implication in vesico-sphincteral physiopathology has been studied since the nineties. METHOD: Literature review of the previous studies having implied menthol in pelvi-perineal physiology through the articles indexed on the Pubmed database, with keywords menthol, menthol and bladder, menthol and toxicity, and TRPM8. Only articles in English were selected. RESULTS: Of the 30 articles that were included, most demonstrated the existence of a micturition reflex to menthol and cold, mediated by the C-type nerve to the spine through activation of TRPM8 urothelial receptors. More recent experiments paradoxically showed an inhibitory effect of menthol on detrusor contractility, independently of TRPM8, when muscle tissue is directly exposed to the compound. However, similar effects of targeted cutaneous exposure or urothelial exposure on detrusorian function have also been demonstrated through TRPM8. This receptor also appears to be involved in interstitial cystitis and idiopathic detrusor overactivity. Lastly, the potential toxicity of menthol appears negligible. Most of the referenced studies are related to animal experiments. Of the three studies that implied humans, only one elucidates some therapeutic applications. CONCLUSION: It seems that menthol and its receptors are involved in vesico-sphincteral physiopathology and could provide therapeutic potential in detrusorian overactivity and interstitial cystitis with reduced toxicity.

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.

[Efficacy of botulinum toxin A injections in the urethral sphincter in patients with difficulties to perform self-intermittent catherization]. / Efficacité des injections intra-sphinctériennes de toxine botulique dans la facilitation technique à la réalisation des auto-sondages.

PURPOSE: To evaluate safety and efficacy of botulinum toxin A injections in the urethral striated sphincter in patients with difficulties to perform self-intermittent catherization. METHODS: In this prospective study, 12 patients suffering from upper motor neuron diseases (8 multiple sclerosis, 2 myelitis, 1 brain injury, 1 multi system atrophy) and with difficulties to perform self-intermittent catherization, defined by a ICDQ score>1 (Intermittent Catheterization Difficulty Questionnaire) have had injections of 100U BOTOX® under EMG guidance in the urethral striated sphincter, for a total of 15 injections. Evaluations consisted of two questionnaires (ICDQ and PGI-A, Patient Global Improvement) 30 days after the injection. RESULTS: 30 days after the injection, ICDQ was improved with a mean decrease of the total score of 7.8 (SD=5.9, P<0,001). In the same manner, all the patients were improved with a mean PGI-A score of 2.3. In 73.3 % of cases, the PGI-A score was equal to 2 (improvement=much better), and in 20 % it was equal to 3 (improvement=a little better). CONCLUSIONS: Botulinum toxin A injections in the urethral striated sphincter in patients with difficulties to perform self-intermittent catherization seem to safe and effective. LEVEL OF EVIDENCE: 4.
