[Bilateral synchronous renal cell carcinoma: report of three cases].

We report here three cases of bilateral synchronous renal cell carcinoma. One of the 3 patients underwent bilateral partial nephrectomy, while the other 2 underwent combined partial nephrectomy and radical nephrectomy. All patients received adjuvant therapy of interferon-alpha and tegafur uracil. In the management of synchronous bilateral renal cell carcinoma, we discussed the selection of surgical procedure for primary lesions, i.e., based on the renal function of both sides, and the necessity of adjuvant therapy in such cases.
