A 59-year-old man was accidentally found to have a right renal tumor (approximately 3 cm in diameter) during a physical examination. Pathology was clear cell carcinoma. RAPN was performed owing to the small size of the renal tumor; however, postoperatively, an intractable urinary fistula with an isolated calyx developed, which was successfully treated with transcatheter renal arterial embolization (TAE).

The patient was a 70-year-old woman who had received maintenance hemodialysis for 8 years due to diabetic nephropathy. She had been treated with weekly administration of darbepoetin 30 μg for renal anemia, which resulted in Hb 12 to 14 g/dL. She had no dysgeusia.

Laboratory tests revealed a marked decrease of serum copper (< 4 μg/dL) and ceruloplasmin (< 2 mg/dL), although serum zinc was within the normal limit (125 μg/dL). We discontinued zinc acetate and started copper supplementation including cocoa for 1 month. Her anemia and granulocytopenia were dramatically restored coincident with the increase in both serum copper and ceruloplasmin. Copper supplementation also improved her iron status as assessed by transferrin saturation and ferritin.
