title: Bilateral synchronous transitional ureteral carcinoma: two additional cases.
abstract: Bilateral synchronous transitional ureteral carcinoma has previously been reported only 11 times. Herein, two additional cases are reported. Analysis shows these tumors to be of relatively low grade and low stage. It is necessary to fully evaluate the opposite side in a patient presenting with unilateral ureteral tumor. If bilateral disease is present, a conservative surgical procedure should be done.
