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.

This volume is a report of the proceedings of the Second International Urological Course held in the Ettore Majorana Centre in Erice, Sicily from the 4-8 November 1978. The meeting was sponsored by the Urological Group of the EORTC (European Organisation for Research in the Treatment of Cancer), the WHO Collaborating Centre for Bladder Cancer, the European Urological Association, the Italian Research Council (CNR) , Italian League against Tumours, Italian Government and Regional Sicilian Government. Contributions were accepted on the understanding that the editors could make certain changes leading towards a uniformity of style but accepting as a priority the importance of early publication, if necessary at the expense of stylistic perfection. Editorial notes have been inserted at infrequent intervals, sometimes to summarise discussions and at others in an attempt to clarify certain issues or to highlight conflicting opinions. Although the work has been divided amongst the editors and co­ editors it is only proper to acknowledge that the major role in collating and in correcting much of the material has fallen on Mrs MAske who has also typed the manuscript. We should also like to acknowledge the kindness of the Yorkshire Regional Cancer Organisation who allowed Mrs Aske to devote much of her time to this work, Miss S Barrowby who has also given considerable secretarial assistance and the Department of Medical Photography, st James''s University Hospital, Leeds whose staff are responsible for many of the illustrations.
