Overactive bladder in clinical practice provides a timely and comprehensive update on the overactive bladder (OAB) syndrome. The symptoms of urgency, with or without urge incontinence, usually with frequency or nocturia, now defined as the overactive bladder syndrome, have become a hot topic in urology, gynecology and urogynecology. Epidemiological data show very high disease prevalence (19%), particularly when compared with other chronic conditions such as diabetes (2%) and asthma (7%). OAB symptoms impact severely on patient’s quality of life, causing significant impairment of patient vitality and limiting their physical role, similar to diabetes. The OAB syndrome involves all age groups, both sexes and is frequently found in neurogenic patients. This book will cover all aspects of OAB epidemiology, economics, pathophysiology, conservative, pharmaceutical and surgical.
