    Abstract:
    OBJECTIVE: To compare the utilization, perioperative complications and predictors of LCA versus RPN in the treatment of localized renal tumors. METHODS: From the Nationwide Inpatient Sample we identified patients undergoing RPN or LCA for the treatment of localized renal tumors from October 2008 through 2010. Patient and hospital-specific factors which predict postoperative complications and use of LCA were investigated. RESULTS: 14,275 patients with localized renal tumors were identified: 70.3% had RPN and 29.7% had LCA. LCA was more common in older patient and at hospitals without robotic consoles. No difference was identified in perioperative complications (0.2% vs. 0.2%), transfusion (5.1% vs. 6.2%), length of stay (2.9 vs. 3.0 days) or median cost ($41,753 vs. $44,618) between the groups, LCA vs. RPN. On multivariate analysis sicker patients were more likely to have LCA (OR 1.34, p=0.048) and sicker patients had greater postoperative complications (OR 3.30, p<0.001); LCA did not predict more complications (OR 1.63, p=0.138) and LCA was performed at hospitals without RCs (OR 0.02, p<0.001). Limitations include observational study design, inability to assess disease severity, operative time, or body mass index, which may affect patient selection and outcomes. CONCLUSIONS: More patients had RPN vs. LCA; surgical technique was not predictive of postoperative complications. As technology develops to treat localized renal tumors, it will be important to continue to track outcomes and costs for procedures including RPN and LCA.
