Clinical guidelines for overactive bladder

To date, it has been considered that overactive bladder (OAB) is a unique disease that only specialists can diagnose, with urodynamic studies required for its diagnosis. However, with the definition of OAB in the standard terminology of the International Continence Society (ICS) being extensively amended in 2002, it is now possible to diagnose OAB on the basis of subjective symptoms and without the complexity of urodynamic studies. Moreover, recent epidemiological research shows that patients with OAB are extremely numerous, and in Japan too, it is estimated that among adults aged 40 years or older, the number of OAB patients is approximately 8.1 million. Thus, OAB is by no means a unique disease, but is rather a condition seen in the everyday clinical setting, and it is expected that not only urologists but also general clinicians will increasingly encounter the disease in the future. Therefore, the Neurogenic Bladder Society has prepared this ‘Clinical Guideline for Overactive Bladder’. This Guideline is structured into two sections: ‘Basic Information on OAB’ and ‘Clinical Guideline’. Because OAB is a new disease concept, the first half of the basic information provides a detailed explanation of the reasons for the change in definition, the mechanism of onset of OAB for each cause, the epidemiology of the disease, and its effects on quality of life (QOL). The second half of the treatment guidelines deal with symptom-based diagnosis, diagnosis by exclusion, and treatment methods for OAB, and present a treatment algorithm reviewed by each member of the drafting group preparing this guideline. In symptom-based diagnosis, the characteristics of each of the symptoms that constitute OAB syndrome are described in detail: urgency, frequency, and urge urinary incontinence. Among these symptoms, urgency is the essential symptom required for diagnosing OAB. Urgency is a pathological bladder sensation, and questioning by the physician must proceed on the understanding that it is completely different to the strong desire to void that occurs in normal individuals when urination is deferred as much as possible. Furthermore, the important aspect in the new concept of OAB is that the patient is able to of the symptoms of OAB as a diagnosis of OAB is not are no symptoms, when the bladder OAB not the diagnosis in patients in symptoms the bladder is completely in of of the treatment methods clinical research and with the treatment of OAB in the years the of OAB has only in in patients are Furthermore, treatment methods are not by to clinical research to the or of is the of treatment for OAB, each also with a Moreover, that are the of for OAB on the treatment of OAB as a of The algorithm for OAB prepared with general in rather The in its to that treatment with can as as possible. a of treatment guidelines for patients with and normal However, is not the patient to a to that the treatment for OAB will only with general and The of this not been possible without the of the drafting group to to to the on the drafting and it will a this to the of specialists and general and the quality of treatment for OAB. In to that this by the Neurogenic Bladder Society has been by the and to the of the by for Bladder Society Overactive bladder (OAB) is as urgency, with and and with or without urge urinary However, for bladder bladder and must In OAB is a in urinary urgency is by symptoms as frequency, and urge urinary The diagnosis of OAB is by of symptoms and of studies are for the pathological of OAB, but are not for diagnosis or the that and the methods of are described the symptoms will described The symptoms are the important for the diagnosis of OAB. The symptoms that constitute OAB are urgency, and and urge urinary incontinence. symptoms are described as by the International Continence Society The symptoms to are frequency, urgency, and urge urinary incontinence. is by the number of Urgency is by its the or of or the of the or the of that the desire to void can urinary is by its or the of as frequency, urgency, and urge urinary are seen as a syndrome in OAB, it is that these symptoms The methods for symptoms of patients to and in bladder questioning is but has that by the by the and of is possible to but as this of by the of a bladder is a and it is that it symptoms, it is a that with of the is to OAB is a syndrome that is of symptoms that frequency, urgency, and urinary incontinence. rather the symptoms it is to a of the are to and in the clinical However, is to that these on a patients with OAB has been and the in Bladder has been is possible that it will the present but it is that it as a symptom for OAB in the has been for the of symptoms in patients with OAB.
