A 62-year-old man with chronic kidney disease (CKD) stage 3 undergoes an abdominal CT for workup of presumed diverticulitis. He is noted incidentally to have bilateral renal cysts and a solid mass in his right kidney. Biopsy of the mass confirms the diagnosis of renal cell carcinoma, and he is scheduled for elective nephrectomy. Prior to his scheduled nephrectomy, the patient is noted to have a serum calcium of 11.4 mg/dL with a serum albumin of 3.6 g/dL. How should this patient's hypercalcemia be approached? What management strategies should be employed?
