The third edition incorporates the technological innovations and new techniques introduced since the publication of the previous editions in 1983 and 1997. A simple, yet practical guide to the functional investigation of patients with incontinence and voiding disturbances, it describes the crucial contribution of urodynamic investigation to the management of patients with lower urinary tract dysfunction. The book focuses on common clinical problems and the presenting symptom complexes rather than diagnosis. The new terminology from the International Continence Society has been corrected, references fully updated and standardization reports in the Appendix completely revised. Urodynamics has since become widely accepted and most hospitals now recognise it to be an essential part of the diagnostic process in urology and gynecology as well as geriatrics, paediatrics and neurology. Any clinician without previous experience in urodynamics will be able to appreciate the value and limitations of these investigative techniques as well as obtaining the necessary practical advice on the use of the appropriate equipment in the correct situations.
