The proceedings of this volume represent a record of a meeting in the Ettore Majorana center in Erice, Sicily from 16-24 July, 1983. This was the fifth course of the International School of Urology and Nephrology, the fourth in a series of meetings devoted to different aspects of Urological Oncology. Speakers and delegates came from nearly every part of the world and contributed to a detailed analysis of the current state of knowledge of tumors of the testicle and to the development of knowledge of cancer of the bladder, prostate and kidney. Previous volumes resulting from this series of meetings have been well received and the Editors hope that the reader may find the record of this meeting equally attractive. We are indebted to the Department of Medical Illustration, St. James's University Hospital, for their kindness in producing several of the illustrations in this book. The editors are very grateful to Dr. Cavallo of Palermo for the major part which he has played in preparing the index. M. Pavone-Macaluso P.H.
