The Textbook of Nephro-Endocrinology is the definitive translational reference in the field of nephro-endocrinology, investigating both the endocrine functions of the kidneys and how the kidney acts as a target for hormones from other organ systems. It offers both researchers and clinicians expert, gold-standard analysis of nephro-endocrine research and translation into the treatment of diseases such as anemia, chronic kidney disease (CKD), rickets, osteoprosis, and, hypoparathyroidism. * Investigates both the endocrine functions of the kidneys and how the kidney acts as a target for hormones from other organ systems. * Presents a uniquely comprehensive and cross-disciplinary look at all aspects of nephro-endocrine disorders in one reference work. * Clear translational presentations by the top endocrinologists and nephrologists in each specific hormone or functional/systems field.
