Urinary Diversion

I am deeply indebted to the radiologists of the Royal Victoria Hospital, and in particular to Doctor D. C. Porter, for a great deal of help and advice, as well as for the X-ray examinations. I am obliged to the visiting medical staff of the Belfast City Hospital who have kindly allowed me to use their notes and X-rays in some cases. I owe the haematological examinations to Doctor M. G. Nelson and the serum iron estimations to Mr. D. Neill. Professor H. W. Rodgers has allowed me to quote his gastroscopy observation in case 5. Any errors or omissions are mine alone. I am obliged to Miss M. Gribbon for typing the manuscript and to Mr. R. Creighton for the photographs.
