The five chapters in this book provide a review of the epidemiology of overactive bladder and an overview of patient evaluation and the existing guidelines. The book addresses lifestyle modification (often ignored by clinicians), therapeutic options and current ‘gold standard’ pharmacotherapy (namely antimuscarinics). There is also a focus on second-line treatments for patients who fail to respond to lifestyle changes and pharmacotherapy, such as sacral nerve stimulation and percutaneous tibial nerve stimulation. The book provides a very practical overview of available approaches and contrasts the pros and cons of therapy, highlighting cost–benefit issues.
