This is a comprehensive, clinically orientated guide to the management of children with all forms of renal disease. Its purpose is to be a portable but complete reference for the day-to-day, bedside, and outpatient management of all conditions, either by the general paediatrician in their own hospital, by specialist paediatric nephrologists, or in shared care between general hospitals and specialized centres. Using bullet points and text boxes, it is easy to use, even in an emergency. The focus is principally on investigation and management, but it also includes some pathophysiology in order to enable better understanding of conditions such as fluid and electrolyte disorders in particular. Where possible, evidence-based recommendations are made, though in the many instances where high-quality evidence is lacking, recommendations are made based on the authors’ personal experience and current best practice. The chapters have been written by four authors who are experienced consultants at three large children’s hospitals in the United Kingdom and the United States.
