Renal and Adrenal Tumors

After the positive response which followed the first edition of this book 6 years ago, the editors were encouraged to prepare a completely reworked second edition that includes the modern advances in this field. There has been a complete change of diagnostic procedure in the detection of renal tumors, which is now based on sonography, computed tomography, and nuclear magnetic resonance imaging, pushing intravenous urography and angiography completely into the background. Also, new methods of treat- ment with radionuclides using embolisation are incorporated. The description of morphological structures forms the basis for under- standing and recognising pathology of the kidneys and adrenals. The con- tents of pathological morphology could be extended, as we are of the opinion that the detection and therapy of renal and adrenal tumors are derived from different areas of diagnostic science. We are indebted to Springer-Verlag for the excellent book production. On behalf of all the authors, we would like to thank our colleagues and associates for their cooperation in the realisation of this project. The editors hope that this volume will be of interest to radiologists, pa- thologists, urologists, pediatrists, and also radiotherapists.
