Kidney dysfunction following adrenalectomy in autosomal dominant polycystic kidney disease complicated with primary aldosteronism: A case report.

The present study reported a case of autosomal dominant polycystic kidney disease complicated with primary aldosteronism in a 49-year-old woman. The patient was referred for refractory hypertension. Laboratory examinations revealed low potassium and renin levels. Computed tomography indicated a right adrenal tumor and multiple renal cysts. Adrenal vein sampling revealed a high aldosterone level on the side of the tumor. The patient was diagnosed with autosomal dominant polycystic kidney disease complicated by primary aldosteronism and adrenalectomy was performed. Over the following 7 months, the estimated glomerular filtration rate decreased from 76 to 48 ml/min/1.73 m, which was attributed to glomerular hyperfiltration correction induced by hyperaldosteronism remission, indicating kidney dysfunction. Clinicians must therefore monitor for the unmasking of kidney dysfunction following adrenalectomy in such cases.
