Nephrology and Endocrinology

Nephrology and Endocrinology

The Division of Nephrology and Eendocrinology provides care for kidney diseases, diseases caused by excessive or insufficient hormone actions, endocrine tumors, and hypertension, which is closely related to problems with both the kidneys and the endocrine system.

Medical services

Board-certified specialists in kidney and endocrine diseases evaluate and treat both outpatients and inpatients. The division also provides outpatient care specializing in hypertension and inpatient programs which include evaluation of and education about hypertension. Since patients with these diseases often require outpatient treatment over a long period of time, each patient is treated by the same physician to ensure the consistent and appropriate care.

Diagnosis and treatment policy

The treatment of each patient is discussed during the weekly rounds led by the head of the division and including all full-time assistants and senior attending physicians. In addition, a group of specialists performs detailed assessment of individual cases. For particularly complicated cases, a case review meeting is convened which includes specialists invited from other departments and external institutions.

Specialties

Kidney failure

Treatment for kidney failure is provided (e.g. hemodialysis for patients with acute and chronic kidney failure; outpatient support services for those receiving home peritoneal dialysis) in cooperation with the Department of Hemodialysis and Apheresis.

Hormone abnormalities

Hormones are produced by various glands, such as the pituitary gland, thyroid gland, parathyroid glands, adrenal glands and gonads, to maintain homeostasis. Abnormal hormone functions manifest themselves in a variety of ways. We perform examinations to identify causes of these abnormalities so as to provide the most appropriate treatment.

Hypertension

We provide the most appropriate treatment for each patient with hypertension to prevent systemic organ dysfunction. Emphasis is also placed on testing and treatment for secondary hypertension caused by adrenal tumors and other diseases.

Target diseases

Acute kidney injury, chronic kidney disease, kidney failure, glomerulonephritis, lgA nephropathy, nephrotic syndrome, electrolyte abnormalities, hypertension, hyperthyroidism, hypothyroidism, hyperparathyroidism, hypoparathyroidism, diabetes insipidus, syndrome of inappropriate secretion of ADH, acromegaly, Cushing’s syndrome, adrenal insufficiency, pheochromocytoma, primary aldosteronism, gonadal failure, disorders of calcium metabolism, osteoporosis, osteomalacia.
