Filter by:The aim of this study is to elucidate whether night-time dosing of mirebegron can improve nocturia, compared with daytime dosing of mirabegron.
Recent phase III trials have confirmed the efficacy and safety of mirabegron in the treatment of overactive bladder (OAB) in Europeans, Australians, North Americans, Japanese and Asians. Whether mirabegron 25mg or 50mg should be used as the first line treatment for OAB has not been determined yet. The dose effectiveness relationship between 25mg and 50mg mirabegron has also not been investigated yet. Hence, investigators have conducted this post marketing study in order to evaluate the efficacy and safety between mirabegron 25mg and 50mg in Taiwanese people with symptoms of OAB.
To investigate whether prolonged period of treatment (6 months) can have a better therapeutic outcome than conventional period (3 months) of antimuscarinics.
Post-treatment Novmalized Urodynamiz Findings as the Golden Standard of Objective Cure for Female Overactive Bladder Patients Receiving Antimuscarinic Drug and Its Conelations With Voiding Diary, King's Health Quentionaire, Overactive Bladder Sympton Scores and Patient Perception of Bladder Condition.
Urethral dilatation is a commonly undertaken intervention for a variety of urinary complaints including overactive bladder symptoms. There is however very little evidence for its efficacy, and no randomized trial evidence. The aim of this study is to ascertain the effect of urethral dilatation on overactive bladder symptoms and on voiding parameters. The null hypothesis is that there will be no difference in symptoms or voiding parameters between the urethral dilatation and sham groups. Eligible women will be assessed initially with a history and examination, a King's Health Questionnaire and Bristol Female Urinary Tract Symptoms (BFLUTS) questionnaire and pressure flow studies. They will be randomized to undergo either cystoscopy alone or cystoscopy and urethral dilatation. Patients will be blinded to the procedure undertaken and randomized using a series of opaque envelopes. Follow up will be at 6 weeks with repeat questionnaires and pressure flow studies. Subjective and objective outcomes will be compared between the two groups.
Importance of the problem OAB is a common health problem. Milsom et al. [1] randomly selected a population from six European countries. From this population, 17% of the respondents reported having OAB symptoms with 14% reporting frequency, 9% urgency, and 6% urge incontinence. The study by Milsom et al. [1] showed that OAB adversely affected the lives of the majority (65%) of the respondents who reported OAB symptoms. Chen et al. [2] also reported that the prevalence of OAB in Taiwanese women was similar to that of Western women. In the study of Chen et al.[2], the prevalence of OAB was 18.6% for the patients; perceptions and the number of OAB condition significantly increased in the elderly women (over 65 years old, 39.3%). Apart from impairing the physical health, OAB may have a tremendous effect on psychological and social well-being. Information on the symptoms and disease severity can yield important information that often complements objective measures. Incontinence, increased urge and increased frequency of micturition affect nearly 100 million people in the western world (33 million in the US and 66 million in the European Union). These conditions are not life threatening but they seriously affect quality of life and ability to work. OAB is in some studies reported to have an incidence of up to 17 % in the western population with great consequences for the quality of life. Economic cost The total economic cost of this group of conditions is high. In 2002 the costs in the US were approximately $12.7 billion[1] (estimated to be $17 billion and €22 billion/year in 2005). Approximately 25% of this expenditure is spent on treatment (drug therapy, clinical consultation and surgery). Of those who suffer only 28% have sought help and only half of those currently receive treatment. Less than 3% regain long lasting normal control. Therefore, these costs are an under-estimate and the problem is large. Aetiology
