Infos

This brand new edition describes in detail the tests involved in urodynamic investigation and shows in which clinical areas these tests can help the management of patients. The authors concentrate on common clinical problems and on the presentation of symptom complexes rather than diagnosis, pointing out any limitations and possible artefacts of investigation.
* The new edition takes into account the technological innovations that have taken place over the last 10 years, while retaining the original objectives of the first edition.
* The subject is presented so simply that a clinician with no previous experience will learn how to use the appropriate equipment in the correct situation.
* Urodynamic investigation is described in such detail that it can be accepted in its own right as a fundamental contribution to the management of many patients.
After reading this book, clinicians will appreciate the value and limitations of the subject and will have obtained the necessary practical advice on which equipment to use in which situation.

Paul Abrams is Honorary Secretary of the International Continence Society, consultant urologist and Chairman of Research at the Bristol Urological Institute based at Southmead Hospital in Bristol. He is also the author of several books in the field.

Lower urinary tract dysfunction produces a huge burden on sufferers in particular and on society in general. Lower urinary tract symptoms have a high prevalence in the community: 5% of children aged 10 wet the bed,while 15% of women and 7% of men have troublesome incontinence; and in elderly men of 75,benign prostatic hyperplasia occurs in more than 80% of indivi- als,with benign prostatic enlargement coexisting in up to half this group and half of these having bladder outlet obstruction. The confusion felt in many people's minds as to the role of urodynamics has receded for the most part. The need to support the clinical assessment with objective measurement has become accepted by most clinicians speci- ising in the care of patients with lower urinary tract symptoms (LUTS). Since the ?rst edition of this book in 1983, urodynamics has become more widely accepted. In the last 20 years the number of urodynamic units in Britain and Europe has increased rapidly and almost every hospital of any signi?cance embraces urodynamic investigations as an essential part of the diagnostic armamentarium of the urology and gynaecology departments. Further, specialists in geriatrics,paediatrics and neurology recognise the importance of urodynamics in the investigation of a signi?cant minority of their patients. Despite the technological innovations that have seen the introduction of computerised urodynamics, the development of neuro-physiological testing and the introduction of new techniques such as ambulatory monitoring, the objectives of this book remain unchanged.
