This volume is concerned with the clinical aspects of urology in
childhood; the anatomy, physiology and pathology are discussed only
where they have a direct bearing upon the clinical problem, and for a
detailed description of these aspects, and of operative technique, the
reader is referred to other volumes of this series. Emphasis is laid
upon the disorders peculiar to infants and children, so that diseases
such as tuberculosis, the manifestations of which in the child differ
little from those in the adult, receive less attention. Childhood is
deemed to cease with the completion of puberty, though illustrations
have sometimes been taken from adolescent cases. The personal views
expressed in this work are based upon experience at The Hospital for
Sick Children, Great Ormond Street, at St. Peter's and St. Paul's
Hospitals, and at the Institute of Urology, University of London. I am
deeply indebted to all my colleagues and assistants at these
institutions for their help and co-operation both in the trea.tment of
cases and in the preparation of this volume. I would particularly wish
to thank Mr. T. T. TwrSTINGTON HIGGINS for introducing me to the urology
of childhood, Drs. M. BODIAN, R. C. B. PUGH and L. L. R. WHITE for their
assistance in matters of pathology, and for preparing specimens for
illustration, Dr. "\V. W. PAYNE for his advice on biochemistry, Dr.
