PY - 2020 T2 - Smith & Tanagho's General Urology, 19e AB - The adrenal cortex is composed of three zones with distinct endocrine functions: zona glomerulosa (produces mineralocorticoids), zona fasciculata (produces glucocorticoids), and zona reticularis (produces sex steroids). The adrenal medulla accounts for approximately 10% of the gland and is composed of chromaffin cells that secrete catecholamines. Disturbances to the hypothalamic–pituitary–adrenal axis (Figure 31–1) result in classic endocrine disorders such as Cushing’s syndrome, hyperaldosteronism, and catechol excess from pheochromocytoma (see Tables 31–1 and 31–2). The diagnosis of these disorders requires careful endocrine and radiographic evaluation.
