Objectives: To compare, retrospectively, the results of laparoscopic partial nephrectomy (LPN) to open partial nephrectomy (OPN) using a tumor size-matched cohort of patients. Limited data are available comparing LPN to OPN in the treatment of small renal tumors.
Methods: Between September 2000 and September 2003, 27 LPNs and 22 OPNs were performed to treat renal masses less than 4 cm.
