METHODS

Within the Surveillance, Epidemiology, and End Result (SEER) Medicare-linked database, 2332 patients who underwent LRN or open/laparoscopic PN for pT1 RCC between 1988-2005 were identified. Postoperative complications within≤ 30 days of surgical intervention were computed, and categorized as either surgical or medical complications. Separate logistic regression analyses were performed for prediction of overall, surgical, and medical complications, where the primary predictor was nephrectomy type (LRN vs. PN).

RESULTS

Respectively 45 and 54% of patients were treated with LRN and PN. LRN-treated individuals experienced lower overall (42 vs. 47%, P= 0.03) and surgical complication rates (20 vs. 29%, P< 0.001) relative to PN. Medical complication rates were identical between LRN and PN in this cohort (both 28%, P= 1.0). In multivariable analyses, LRN was associated with lower …
