A 62-year-old man was referred to our clinic with a chief complaint of gross hematuria. He had bilateral renal staghorn calculi at the age of 50 years and had undergone left nephrolithotomy. However, no treatment had been given to the right staghorn calculi associated with nonfunctioning kidney. Imaging diagnosis demonstrated no mass lesions in the bilateral kidneys. Right nephrectomy revealed renal cell carcinoma, tubular type, mixed subtype, G2, INF-beta with lymph node metastasis to the renal hilum. Cancer cells infiltrated diffusely throughout the entire renal parenchyma. He died of progressive metastases 15 months postoperatively.
