[Simultaneous enucleo-resection of synchronous bilateral renal carcinoma, incidentally discovered during prostate disease screening].

Bilateral synchronous renal cell carcinoma is rare, incidental discovery is exceptional. We report a case of asymptomatic bilateral simultaneous renal tumor discovered during screening for prostatic disease. Two year previously the patient underwent sonography and IVP for right ureteral stone, spontaneously ejected, with no evidence of renal masses. Ultrasound, CT and selective digital angiography demonstrated two renal tumors < 3 cm in size. Bilateral simultaneous enucleoresection was the therapeutic choice, that we consider to be elective in such a case.
