Editor in Chief

“Hypospadias Surgery, An illustrated guide” by Springer Verlag, Germany, 2004

This is the first international book on hypospadias surgery. It highlights current philosophy and different principles of hypospadias repair. The aim of the book is to help interested surgeons to develop vision and talent rather than just enumerate techniques. It is well illustrated with over 465 colored diagrams and photographs of various operations. In the book, a team of world class authors from 5 continents present an expert overview on the management of this common but troublesome disease.
