Pheochromocytomas are catecholamine-producing neuroendocrine tumors derived from the adrenal neuroectoderm. The estimated incidence of pheochromocytomas ranges from 0.005 to 0.1% of the general population and from 0.1 to 0.2% of the adult hypertensive population [To date, retroperitoneoscopic adrenalectomy (RA), transperitoneal laparoscopic adrenalectomy (TA), and open adrenalectomy (OA) are frequently used techniques for removing adrenal tumors including pheochromocytoma [
