ABSTRACT Estimate the prevalence of urinary incontinence (UI), overactive bladder (OAB), and other lower urinary tract symptoms (LUTS) among men and women in five countries using the 2002 International Continence Society (ICS) definitions.
This population-based, cross-sectional survey was conducted between April and December 2005 in Canada, Germany, Italy, Sweden, and the United Kingdom using computer-assisted telephone interviews. A random sample of men and women aged >/= 18 yr residing in the five countries and who were representative of the general populations in these countries was selected. Using 2002 ICS definitions, the prevalence estimates of storage, voiding, and postmicturition LUTS were calculated. Data were stratified by country, age cohort, and gender.
A total of 19,165 individuals agreed to participate; 64.3% reported at least one LUTS. Nocturia was the most prevalent LUTS (men, 48.6%; women, 54.5%). The prevalence of storage LUTS (men, 51.3%; women, 59.2%) was greater than that for voiding (men, 25.7%; women, 19.5%) and postmicturition (men, 16.9%; women, 14.2%) symptoms combined. The overall prevalence of OAB was 11.8%; rates were similar in men and women and increased with age. OAB was more prevalent than all types of UI combined (9.4%).
The EPIC study is the largest population-based survey to assess prevalence rates of OAB, UI, and other LUTS in five countries. To date, this is the first study to evaluate these symptoms simultaneously using the 2002 ICS definitions. The results indicate that these symptoms are highly prevalent in the countries surveyed.

    ABSTRACT: The aim of this study was to identify the efficacy and safety of Baweidihuang-wan (BWDH) in women with overactive bladder (OAB) and to investigate whether BWDH is more effective in OAB diagnosed as kidney yang deficiency pattern by the Korean medical pattern identification. The design of this study was a randomized, double blind, placebo controlled trial. One hundred eighty-six women with OAB were randomized to treatment (n=93) or control group (n=93). Participants received BWDH or placebo three times a day for eight weeks. Efficacy was assessed by overactive bladder symptom score and 3-day bladder diary. Subgroup analysis was conducted between kidney yang deficiency pattern and other patterns according to the Korean medical pattern identification. One hundred sixty-four participants completed this trial. The treatment group has improved in OABSS score, Total micturitions per 24 hr, Daytime micturitions per 24 hr, Total count of urgency, and Total urgency score over the control group, but differences were not statistically significant. By a subgroup analysis, OABSS score, total micturitions per 24 hr, total count of urgency and total urgency score improved most in the treatment group with the kidney yang deficiency pattern but this was also not statistically significant. No obvious adverse events were found in the use of BWDH. In conclusion, this trial did not show significant difference between BWDH and placebo in women with OAB. However BWDH tended to improve urinary frequency and urgency in OAB, especially diagnosed as kidney yang deficiency pattern. Further additional research will be needed.

    ABSTRACT: Overactive bladder (OAB) is a common problem that may occur in individuals of all ages. It has a considerable impact on patient quality of life, and although moderately effective management strategies do exist, this condition often remains undiagnosed and untreated. OAB needs to be viewed as a symptom complex. Its presentation and management are complicated in the vulnerable elderly by the presence of baseline frailty and multiple coexisting chronic conditions. Furthermore, and beyond a simple understanding of symptomatology, providers must address patient goals and motivations as well as the expectations of caretakers. These multiple levels of perception, function, expectations, and treatment efficacy/risks must be tailored to the individual patient. While the vulnerable elderly patient may often have evidence of urinary tract dysfunction, OAB and urge urinary incontinence in this population must be understood as a multifactorial geriatric syndrome and viewed in the context of medical and functional baseline and precipitating risk factors. Expectations and goals must be tailored to the resources of vulnerable elderly patients and their caregivers, and care must be coordinated with other medical care providers. The management of OAB in the vulnerable elderly often poses significant management challenges. Nonetheless, with a thoughtful approach and an aim towards future research specifically for this population, significant reductions in morbidity and mortality long with enhancement in health-related quality of life are possible.

    ABSTRACT: Overactive bladder (OAB)/ storage lower urinary tract symptoms (LUTS) have a high prevalence affecting up to 90% of men over 80 years. The role of sufficient therapies appears crucial. In the present review, we analyzed the mechanism of action of tolterodine extended-release (ER) with the aim to clarify its efficacy and safety profile, as compared to other active treatments of OAB/storage LUTS.
