AQUA: A NEW QUESTIONNAIRE ASSESSING ANTICHOLINERGIC SIDE EFFECTS IN NEUROGENIC POPULATION (AQUA: Anticholinergic Side Effects QUestionnAire)

Lower Urinary tract symptoms (LUTS) are widespread in the general population and their prevalence is expected to increase in the coming years as the elderly population increases. Indeed, overactive bladder syndrome (OAB) is very frequent and increase with age. OAB has numerous and various etiologies and can be caused by urologic, metabolic, neurogenic or autonomic dysfunction. Treatments for OAB depends on etiology but first line treatment often corresponds to lifestyle modification and antimuscarinics. Antimuscarinics allows improvement for OAB symptoms, quality of life and urodynamic parameters. However, antimuscarinics adherence is poor and anticholinergic drugs are often withdrawn few months after their introduction. This low adherence to antimuscarinics can be explained by side effects as dry mouth, blurred vision, constipation or cognitive impairment which are due to systemic anticholinergic effects since specificity and receptor affinity of bladder antimuscarinics are poor with a large distribution of acetylcholine receptors in all the body. Unfortunately, there is no or a few questionnaires which evaluate side effects or constraints, except for one published in 2019, but not specific for anticholinergics. This part of evaluation is poorly reported in medical literature, whereas it seems to be clear that side effects should be systematically evaluate and are in part responsible of treatment discontinuation. The objective of the study is to develop and validate a new questionnaire to assess side effects of antimuscarinic treatment in a patient with OAB. The study was conducted in a Neuro-urology Department of a University Hospital. To allow a full psychometric validation of the questionnaire, the study protocol included 3 steps: qualitative interviews, feasibility study and validation study. The inclusion criteria were to be aged > 18 years and to have OAB symptoms according to the ICS definition and secondary to a neurogenic dysfunction. First step of the study consisted in a review literature on Pubmed to explore the different side effects secondary to antimuscarinic treatment and do determine which tools were available. In addition, we conducted semi-structured interviews on 30 patients suffering from OAB. Feasibility Study For this feasibility study, 30 patients were included. They had to rate each item to evaluate comprehension, acceptation and pertinence with a three-points Likert scale from response "0: not at all or quite" to "2: perfectly". Validation study: 100 patients Content validity was assessed by the panel of experts. Internal consistency reliability was calculated using the ? coefficient of Cronbach. Each response has been transformed in a numeric value to perform this test. Alpha coefficient of Cronbach was considered as very good if > 0.7. Test-retest reliability was tested using the intraclass correlation coefficient (ICC) which was significant over 0.7. The first questionnaire was filled at the end of the first consultation and patients had to answer a second questionnaire (filled at home) 7 days after the first consultation. Objective was to validate this questionnaire with good or very good psychometric properties. Primary outcome was Alpha coefficient of Cronbach and ICC ? 0,7.

Intravaginal Electrical Stimulation With Different Treatment Frequency in Women With Idiopathic Overactive Bladder

Electrical stimulation (ES) is one of the techniques used in urogynecological physiotherapy, which uses implanted or non-implanted electrodes. Intravaginal ES (IVES) is a conservative treatment option, described more than 40 years ago. IVES is used in patients with OAB and urge urinary incontinence (UUI), for detrusor inhibition. It has been suggested that IVES probably targets the detrusor muscle or pelvic floor muscle (PFM) or afferent innervation in UUI. According to the European Association Urology (EAU) Guidelines; in adults with urinary incontinence, ES may improve urinary incontinence compared to sham treatment. The IVES programs lasted between 4 weeks and 6 months in women with idiopathic OAB, although generally IVES was applied for 4-12 weeks. In most studies, IVES was applied 2-3 times a week, whereas in fewer studies it was applied more frequently. Despite that, no randomised studies compared different treatment frequencies in women with idiopathic OAB and thus, there is no evidence of which frequencies of treatment are the most effective ones. It should be kept in mind that different stimulation frequency may lead to different results. In addition, in the light of scientific evidence and our clinical experience, we think that this issue is still open for research. Better methodological quality studies are needed to obtain a higher level of scientific evidence and to know the optimal treatment frequency for OAB. Our study is the first prospective randomized controlled trial that compares the efficacy of IVES with different treatment frequency in women with idiopathic OAB. In this study, we aimed to assess the efficacy of 2 times and 5 times in a week IVES added to BT on quality of life (QoL) and clinical parameters asssociated with idiopathic OAB. The results of the our study will be of great benefit in deciding or preferring the treatment frequency and total treatment duration of IVES for the women with idiopathic OAB and their physicians.

Antibiotic Usage Prior to OnabotulinumtoxinA Injection

Intradetrusor injection of onabotulinumtoxinA, which is performed through a cystoscopic procedure, has been demonstrated to be efficacious in the treatment of both neurogenic and non-neurogenic overactive bladder (OAB), and is FDA approved as a treatment for overactive bladder. Intradetrusor of onabotulinumtoxinA is currently standard of care of patients with OAB who have persistent OAB symptoms despite behavioral therapies and oral medication treatments for OAB. As one of the main adverse events associated with intradetrusor injection of onabotulinumtoxinA is UTI, and published guidelines for cystoscopic procedures with manipulation recommend the use of prophylactic antibiotics, a single dose of prophylactic antibiotic is administered prior to this procedure. However, these recommendations are primarily based on data from randomized controlled trials (RCTs) involving antimicrobial prophylaxis during transurethral resection of the prostate. A previously published prospective study demonstrated that the rate of post-procedural UTI did not differ amongst patients with neurogenic bladder who did not receive prophylactic antibiotics and were asymptomatic for UTI, regardless of whether they had sterile urine cultures or asymptomatic bacteriuria, suggesting that patients who are not symptomatic for UTI may not require antibiotic prophylaxis prior to intradetrusor onabotulinumtoxinA injection. Studies have reported that up to 50% of antibiotic usage is inappropriate, leading to unnecessary exposure of patients to potential complications of antibiotic therapy, including Clostridium difficile infection which can cause recurrent diarrhea that may progress to sepsis and death, increasing antibiotic resistances, as well as dermal/allergic and gastro-intestinal manifestations. Therefore, in an effort to optimize antibiotic use, the investigators propose a prospective, randomized study to formally evaluate the differences in UTI frequency in subjects who have a negative urinalysis and are not symptomatic for UTI and receive prophylactic antibiotics at the time of intradetrusor onabotulinumtoxinA injection compared to those who do not receive prophylactic antibiotics at the time of injection. The proposed study seeks to evaluate the current practice standard of antibiotic prophylaxis prior to intradetrusor onabotulinumtoxin injection.
