Partial nephrectomy of a huge solid-cystic renal mass with final pathology of renal cell carcinoma.

Partial nephrectomy has been established as a standard treatment of renal mass <4 cm(cT1a), but mostly it is performed in larger tumors of size up to 7 cm (cT2b). The maximum size of a tumor that could undergo partial nephrectomy is controversial. In this case report, we present a case of a large renal mass (17 cm) that underwent open partial nephrectomy successfully. To our knowledge, this case is the giant tumor that underwent partial nephrectomy in the literature. Partial nephrectomy could be performed if technically feasible irrespective of the tumor size.
