This book represents a combination of commonly seen childhood renal problems. The editors have fulfilled their goal of producing a reference monograph for pediatricians, pediatric nephrologists, general nephrologists and others involved in pediatric care in India. The twelve years time between the second edition and third edition is a reflection of the meticulous effort put in by the editors for this volume. Apart from eminent Indian contributors, faculty also includes renowned pediatric nephrologists and neonatologists from the United States of America.

The initial part of the book contains articles on basics of nephrology while the final component concentrates on different aspects of renal disease in children. The editors’ concept of producing a book with a judicious combination of both functional nephrology and clinical nephrology is noteworthy. Every common aspect of pediatric nephrology is covered in a simple language with a practical orientation. I appreciate the efforts of Dr BR Nammalwar and Dr M Vijayakumar, eminent Indian pediatric nephrologists, for bringing out this textbook, which is practical, easily understood, and state-of-the-art. I wish their venture success.

Our friends Dr N Somu, Dr L Subramanyam, Dr A Balachandran, Dr K Nedunchelian, Dr NC Gowrishankar, Dr S Lakshmi and Dr So Shivbalan have contributed extensively in every respect in the production of this book as in the earlier edition.
