Abstract:
Background:Unilateral adrenalectomy is indicated for patients with unilateral primary aldosteronism resulting in normalization of hypokalemia and resolution of hypertension. This study aims to determine the proportion of patients with cure of hypertension and improvement of hypokalemia after unilateral adrenalectomy among patients with aldosterone-producing adenoma and assess the association of preoperative factors with these outcomes.
Methods:This is a retrospective cohort study among patients with aldosterone-producing adenoma who underwent unilateral adrenalectomy with at least one month follow-up after the operation. Patients were selected from admissions to the University of Santo Tomas Hospital from January 2008 to November 2018. The proportion of patients with cure of hypertension and resolution of hypokalemia were determined. Binary logistic regression was used to determine preoperative factors associated with these outcomes.
Results:Twenty-one patients were included in this study. Cure of hypertension was noted in 47.62% and 42.86% of patients within 24 hours of adrenalectomy and on follow-up, respectively. Improvement of hypokalemia was noted in 61.90% of patients within 24 hours of operation while all patients had improvement of hypokalemia on follow-up. Patients without preoperative hypokalemia were more likely to have cure of hypertension within 24 hours of adrenalectomy (OR=0.0250, p=0.005) and on follow-up (OR=0.0571, p=0.010).
Conclusion:Unilateral adrenalectomy results in improvement of hypertension and hypokalemia in the majority of patients with aldosterone-producing adenoma. Shorter duration of hypertension and absence of preoperative hypokalemia were significantly associated with cure of hypertension after unilateral adrenalectomy. - Full text:8 - A Retrospective.pdf
