Technology seems to be an integral part of modern living. Urologists have over the years embraced new technological advances for patient beneft. On some occasions, however, the initial enthusiasm in something new has failed to endure rigorous scientifc scrutiny. Thus, while being technological leaders, we urologists know better than most other surgical speci- ties that what is new is not necessarily good. This textbook is aimed at urologists and surgeons at all levels and has contributions from international experts. The topics vary from robotics to lasers to single port laparoscopy. The comprehensive chapters should be of equal interest to uro-oncologists and those involved in treating benign urological diseases. While the contents are meant to bring the reader up to date with technological advances, the authors have attempted to balance their enthusiasm with basic science, translational research, and clinical outcomes. It will be obvious that some of the s- jects mentioned here, such as nanotechnology, are still evolving, and it will be a while before they undergo clinical trials that establish their position in clinical medicine. We hope you enjoy reading this book as much as we have enjoyed creating it.

In keeping with the aims of other books in this Series the Editors have concentrated on the practical aspects of management -in this case of the urinary tract in patients with spinal cord injury. It is well accepted that the management of such patients is best done by those with special experience in this field. Nevertheless, it is essential that urologists should be well informed on matters relating to the neuropathic urinary tract since not all patients will be managed in special centres and, whether their problems are acute or chronic, the wrong clinical decision can lead them into a lifetime of problems. The plan of this book is directed towards examining particular problems and providing definitive answers. Even in this enlightened age of medical progress there are many clinical situations where there is often a choice of treatment. Readers of this Series will be aware that, despite an apparent abundance of information on a topic, it is sometimes not possible to reach a firm conclusion on a management problem. Keith Parsons and John Fitzpatrick are to be congratulated on ensuring that for this subject there are good clear guidelines. The data in the book are up to date and the excellent approach to the subject makes it a valuable addition to Clinical Practice in Urology.
