Partial nephrectomy for renal tumors using selective parenchymal clamping.

Purpose: To describe our experience with partial nephrectomy using selective parenchymal clamping for the treatment of renal tumors.

Patients And Methods: Between 2003 and 2005, seven patients with solid renal tumors underwent partial nephrectomy with selective parenchymal clamping at our Institution. In five, the tumor was in the right kidney and in two the tumor was in the left.

Introduction: Renal oncocytoma is a benign tumor that in some series represents up to 18% of all solid neoplasms measuring 4 cm or less. Since radiologic distinction between a renal cell carcinoma and oncocitoma is practically impossible, the histologic examination represents the cornerstone of diagnosis. Follow up will be greatly modified by the diagnosis of oncocytoma since it displays a benign course.
