This second edition of Urodynamics details the technological innovations and new techniques that have accompanied a rapid expansion of the field since the mid 1980s. The objective is to put the subject of urodynamics over simply, but in enough detail to allow urodynamic investigation to be accepted on its own merit as a fundamental contributor to the management of many patients. The text describes the tests involved and shows in which clinical areas they can help the management of patients. It concentrates on common clinical problems and the presenting symptom complexes rather than the diagnosis, and points out any limitations and possible artefacts of investigation. This book aims to allow any clinician with no previous experience in urodynamics to appreciate the value and limitations of the subject and to obtain the necessary practical advice on the use of the appropriate equipment in the correct situations.
