[Simultaneous presentation of bilateral renal adenocarcinoma. Therapeutic possibilities]

Bilateral renal adenocarcinoma accounts for 1.4% to 5% of all renal adenocarcinomas. Currently, an increased incidence of synchronous bilateral renal adenocarcinoma has been observed, which can be ascribed to the availability of more sophisticated high resolution ultrasound and computed tomography. Several surgical options exist, such as bilateral radical resection, radical surgery combined with partial nephrectomy or tumor enucleation for the contralateral side, and partial nephrectomy or tumor enucleation for both sides. Two cases of synchronous bilateral renal adenocarcinoma are described. One case was submitted to a left superior partial nephrectomy and enucleation of the tumor in the right kidney. The other patient underwent a left radical nephrectomy and excision of the inferior pole of the right kidney.
