Adrenalectomy aims to remove an abnormal or diseased adrenal gland while managing the patient's hormonal requirements before and after surgery. The procedure may be required for conditions such as functioning adrenal tumors, adrenal cortical tumors, pheochromocytoma, or suspected adrenal malignancy. Treatment planning involves detailed imaging and biochemical testing to determine whether the tumor is producing hormones and to assess its relationship with nearby structures. Postoperative monitoring may include blood pressure, electrolyte, and hormone assessment, particularly after removal of a functioning tumor or both adrenal glands.
