Nephrology
concerns itself with the diagnosis and
treatment of kidney diseases including electrolyte disorders and hypertension, and the care of those requiring renal replacement therapy, including dialysis and renal transplant patients. Many diseases affecting the kidney are not limited to the organ itself, but are systemic disorders, and may require not only a whole patient approach, but also special treatment, such as systemic vasculitides or other autoimmune diseases, such as lupus.
