Owing to its central position in the retroperitoneal and pelvic cavity, the ureter is rapidly affected by a variety of pathological processes. Furthermore, any disease involving the ureter can also have an effect on the kidneys. For several decades, the diagnosis of diseases affecting the ureter was based on intravenous excretory urography and techniques of direct opacification. However, the diagnostic strategy has been extensively modified by the advent of helical computed tomography and magnetic resonance imaging. This book, the first to focus specifically on ureteral imaging, covers both the new and the traditional techniques. Their use in the variety of scenarios involving ureteral disease is clearly elucidated with the aid of high-quality informative images.

This valuable review book provides a thorough framework for the basic principles of neonatology in a clear and user-friendly style.

The focus is on examination and diagnosis of both common and atypical disorders, with brief details of medical and surgical treatment where appropriate.

Hormonal carcinogenesis is an important and controversial area of research. In addition to accelerating existing cancers, can hormones play the role of primary carcinogens? And how do genetic factors influence hormone-related cancer risk? This work addresses these questions. During the last few decades of the 20th century, cancer research focused on external environmental causes (for example, tobacco smoke, viruses, asbestos). With the advent of genetic sequencing techniques, we are just now beginning to understand how the body's internal environment (that is, the hormones and growth factors that determine normal development) influences cancer etiology and prevention. From molecular insights to clinical analyses, this volume provides state-of-the-art information on the complex interactions between hormones and genes and cancer. The epidemiology and molecular endocrinology of prostate, breast, uterine, ovarian and testicular cancer are detailed in this timely treatise.

This highly acclaimed book deals with all the key kidney, ureter and bladder problems likely to be encountered by the non-specialist paediatrician and paediatric nephrologist. The book adopts an evidence-based, problem solving approach and focuses on presenting clinical symptoms rather than being disease orientated. Emphasis is placed on differential diagnosis, evaluation and treatment. Where no evidence is available or where controversy exists, a clear opinion on the most appropriate treatment is provided. For this completely revised and updated edition over half of the text is revised. New chapters have been added on psychosocial care principles, drug prescribing in children and paediatric nephrology in the third world. Certain chapters have been condensed for clarity and other chapters have been combined to facilitate practical use. This edition is based around practical guidelines and contributions have been collected from international experts in the field. The chapters contain key point boxes highlighting the important take-home messages. The well-structured text is ideal for trainee and non-specialist paediatricians, for paediatric nephrologists and for nephrologists and urologists with an interest in children. This book is undoubtedly regarded as 'the' paediatric nephrology textbook to be held on the shelves of all general paediatric departmental libraries.
