Kim et al identified risk factors for identifying chronic kidney disease in patients who have undergone adrenalectomy for primary aldosteronism. The authors are from Sungkyunkwan University in Seoul, South Korea.

Outcome: chronic kidney disease (eGFR < 60 mL per min per 1.73 square meter)


Postoperative renal impairment was defined as an eGFR decline > 25% of preoperative eGFR (postoperative eGFR < 0.75 * preoperative eGFR)


Risk factors for postoperative identification of CKD:

(1) older age (above 50 years of age; odds ratio 1.13 per year)

(2) low serum potassium (odds ratio 0.35 per mmol/L)

(3) high serum cholesterol (odds ratio 1.03 pr mg/dL

(4) high serum uric acid (odds ratio 1.6 per mg/dL)

(5) chronic hypertension (odds ratio 1.23 per year)

(6) low BMI (odds ratio 0.86)
