Simultaneous bilateral retroperitoneal laparoscopic nephron sparing surgery: a case report and evaluation of the technique

Bilateral renal cell carcinoma (RCC) is an extremely rare renal tumor, which even more infrequently presents with two different types of pathology. We present a case of bilateral RCC in a 56-year-old male patient treated with simultaneous retroperitoneal laparoscopic nephron-sparing surgery (RLNSS). The postoperative histopathologic examination identified the left tumor as a clear cell carcinoma and the right as a chromophobe cell carcinoma. The patient received no adjuvant therapy and was alive at the 15-month follow-up examination. As far as we are aware, it is the first case of bilateral RCC of different pathologic types in the two tumors that was treated with simultaneous RLNSS. This technique can be extended due to the benefits of the short postoperative recovery period and wide acceptance among patients.
