title: [Surgical enucleation for renal cell carcinoma. A case report].
abstract: We present a case of bilateral synchronous renal cell carcinoma treated with surgical enucleation. Urological consultation was asked to evaluate masses of the kidneys, which were detected during a diagnostic imaging on a 58-year-old man with hepatic disorder. Excretory urograms showed definite bilateral upper pole renal masses. Bilateral selective renal angiograms disclosed neovascularity in the small masses. Surgical enucleation of the left renal tumor by a flank approach was performed. The surgical specimen being 3.5 by 2.5 by 2 cm (29 g) was pseudoencapsulated and was identified renal cell carcinoma of the clear cell type, grade 1. INF alpha, pathologically. Seven weeks after, a pseudoencapsulated tumor of 3 by 2.5 by 2 cm (16 g) in the right upper pole was removed by simple enucleation. The pathological diagnosis was renal cell carcinoma of clear cell type, grade 2, INF alpha. The patient is well without evidence of recurrent or any residual disease at 21 months after the second operation. Renal function remains with in normal limits (CCr 110 ml/min). Of our collected cases of bilateral synchronous renal carcinomas treated by bilateral conservative surgery, clinical data are available for 11. Including our case, a total of 12 cases are reviewed.
