The Lingering Battle of Persistent Hypoaldosteronism Following Adrenalectomy for Primary Aldosteronism: A Case Report.

Persistent hypoaldosteronism post-adrenalectomy for unilateral primary aldosteronism is not uncommon and should be anticipated in patients with risk factors for development of such condition. Most cases of hypoaldosteronism postadrenalectomy are transient. However, persistent hypoaldosteronism may occur as a result of delayed recovery of contralateral zona glomerulosa suppression, requiring mineralocorticoid replacement for the prevention or treatment of life-threatening hyperkalemia.
