View clinical trials related to Overactive Bladder Syndrome.
Filter by:Until now, OAB with or without UUI has been treated mainly in two ways: with behavioral methods and/or patient education or using antimuscarinic drugs and/or beta 3 adrenergic receptor agonists. Unfortunately, the drugs might cause side effects in some women or were insufficiently effective, so the patients abandoned them. Methods In prospective, randomized, placebo controlled study, 80 women were enrolled, using radiofrequency in treating OAB and UUI. Based on ICIQ-OAB, ICIQ-OAB QoL, and ICIQ-FLUTSsex questionnaires, severity of OAB symptoms, QoL and detailed evaluation of female sexual matters associated with their lower urinary tract symptoms. RF was applied 4 times for 20 minutes, once a week. Two week after the completion of the treatment,as well as 3, 6 and 12 months, the level of OAB and UUI was reassessed and processed it statistically and evaluated the treatment effect.
A prospective, multi-center, study comparing continuous sacral neuromodulation (SNM) stimulation to daily cyclic stimulation of 2 hours "on" and 22 hours "off" using the Axonics System.
Patients with either overactive bladder (OAB) or urgency urinary incontinence (UUI) with be randomized (like a flip of a coin) to receive 100 units of bladder Botox® at either one injection site or ten injection sites. Efficacy and patient satisfaction will be measured by questionnaires.
The aim of the original study was to compare Incobot/A versus Onabot/A in order to evaluate if the differences in the pharmacologic formulations between the two drugs could affect their efficacy and safety in the treatment of neurogenic overactive bladder (OAB). In the original study protocol two different dosages for either Incobot/A and Onabot/A (200 U and 100 U) were considered, to treat patients with neurogenic detrusor overactivity incontinence performing intermittent catheterization (IC) with higher dosages and those able to void spontaneously with lower dosage, with the resulting four treatment groups. For such a study, a very large sample of participants should have been treated and followed up, to have adequate power to demonstrate the hypothesis. At the end of last February 2020, we had to temporarily stop all the clinical activities related to the study and patients' recruitment, due to the occurrence of Sars-Cov-2 pandemic in our Country. At that point, a non-inferiority study seemed to be possible and adequate, and we adapted the protocol accordingly. In addition, on the basis of previously published information, we could hypothesize that the new drug (Incobot/A) would have had at least a roughly similar effect to the control drug (Onabot/A). In order to perform a non-inferiority study, the power and sample size analysis have been re-planned. Thus, we perform a not planned interim analysis to show the preliminary results of an ongoing, non-inferiority trial in which patients' recruitment temporarily stopped due to incontrollable external factors. The present study will be aimed to assess the non-inferiority of Incobot/A compared to Onabot/A on the efficacy and safety parameters, in the treatment of patients with refractory NDOI performing IC, who are randomized to receive 200 U of Incobot/A or Onabot/A intradetrusor injections and who are followed up to 12 wks after treatment
Rationale: The sensation of the need for urination (urge) is a complex and only partially understood mechanism. It is our hypothesis that this mechanism is disrupted in patients suffering from overactive bladder syndrome. The Overactive Bladder syndrome (OAB) has been defined as a spectrum of symptoms in which incontinence may or may not overlap with urgency, frequency and nocturia. This syndrome is estimated to affect approximately 17% of the adult population in Europe and the United States. The symptoms of overactive bladder have many potential causes and contributing factors. One of these factors is an outlet obstruction of the bladder due to benign prostatic hyperplasia (BPH). Nowadays antimuscarinic drugs are used for treatment of the overactive bladder. Antimuscarinic agents have been proven to work slightly to moderately better than placebo's and are associated with side effects such as a dry mouth, blurred vision and constipation. Many patients with lower urinary tract symptoms (LUTS) develop OAB. In this group of patients with LUTS and OAB, there is not always a clear obstruction found. So, at least in some patients, with LUTS, there must be another reason for OAB than obstruction. The autonomous bladder activity has been introduced by, among others the Maastricht Urology research group. In animal models, the bladder is shown to have rhythmic low amplitude contractions (micro motions). It is hypothesized that this activity has a sensory function in the micturation regulation system which is mainly located in the bladder wall. These so called micromotions have never been demonstrated in the human bladder. The sensing function of the bladder and the micturation reflex remain mainly unclear. We hypothesise that there is a disregulation of the autonomous bladder activity (micro motions) in patients with OAB. We want to explore and study the relationship between OAB, obstruction and the micro motions in order to gain a better understanding of the bladder (patho)physiology. reason for This on its turn, can help us in the quest for better treatment strategies for patients suffering from OAB. Objective: The study is divided in two distinct groups a male and female group: The male group consist of patients with lower urinary tract symptoms (LUTS). The female group consist of patients with the overactive bladder syndrome OAB. The primary objective of this pilot experiment is to describe via an observational study the relation between non-micturation bladder activity and sensation during the filling phase of the bladders in women. We want to explore if there is a relation between non-micturation bladder activity and the sensation of urgency during the filling phase. Furthermore in men, we want to study the relationship between non-micturation bladder activity and the amount of obstruction. We would also like to visualize the micro motions of the bladder in both men and women during filling phase and study the influence of (visual and cognitive) stimuli on bladder activity. We want to explore if there is a relation between non-micturation bladder activity and the sensation of urgency during the filling phase in male patients with Lower urinary tract symptoms. In order to gain a better understanding in bladder (patho)physiology. Study design: A pilot observational study to describe the non-micturation bladder activity and sensation measurement during filling phase. Study population: The study population consists of two groups. First a group of patients (female) who will undergo an ambulatory urodynamic investigation to investigate their bladder complaints. All patients will be older than 18 years. The second group consists of male patients who will undergo a conventional urodynamic investigation in the normal work up for their lower urinary tract symptoms. All patients will be older than 18 years.
