of sources. When prescribing medication, healthcare professionals are advised to consult the product
information sheet (the manufacturer’s package insert) accompanying each drug to verify, among
other things, conditions of use, warnings, and side effects and identify any changes in dosage
schedule or contraindications, particularly if the medication to be administered is new, infrequently
used, or has a narrow therapeutic range. To the maximum extent permitted under applicable law, no

PREFACE
In this fifth edition of Renal Pathophysiology: The Essentials, we have
maintained the general principles that guided us in the design and approach
of the last four editions of the book. Over these last years, we have received
many comments and suggestions not only from our second-year medical
students but also from house staff, nephrology fellows, and colleagues; we
are most grateful for their feedback and encouraging words. As a
consequence of these suggestions, we have further expanded the sections on
molecular aspects of the mechanisms that result in kidney dysfunction and
the morphologic expression of the major diseases that affect the kidney; the
illustrations are in full color and inserted into the text. The list of suggested
readings has been updated and summaries are included at the end of
physiology chapters. We have also reviewed supplemental self-examination
questions that permit application of key concepts to clinical cases and to
develop more nuanced understanding. However, the core and the principal
aim of this book remain unchanged: to provide the student with a solid
understanding of the mechanisms that result in kidney dysfunction and
disease and to serve as the basic reading material and text for a course in
kidney pathophysiology.
