Nephrology Nephrology is the medical field that focuses on diagnosing and managing kidney diseases in both adults and children. Nephrologists specialize in treating various kidney-related conditions, such as chronic kidney disease (CKD), kidney stones, and acute kidney injury, while also helping patients with kidney replacement therapies like dialysis and transplantation. Since the kidneys play a key role in maintaining the body's fluid and electrolyte balance, nephrology is closely related to hypertension management. Kidney disease is a growing global concern, ranking as the 12th leading cause of death worldwide.
