Abstract
PURPOSE: To evaluate patient outcomes in a contemporary cohort of patients undergoing partial nephrectomy (PN) or radical nephrectomy (RN). METHODS: The NSQIP database was used to identify patients undergoing PN or RN for renal neoplasms between 2010 and 2018. The SEER database was also queried to assess changes in tumor staging during the study period. Logistic regression was used to assess the independent relationship between surgery year and approach on postoperative complications. RESULTS: Between 2010 and 2018, NSQIP captured 58,020 cases, including 26,745 (46%) PN and 31,275 (54%) RN. The proportion of PN increased annually, from 39.8% in 2010 to 48.7% in 2018. This rise in PN coincided with a decrease in the proportion of patients experiencing complications, irrespective of surgical approach (20.4% of total cases to 14.2% of total cases). While limited by a lack of information on tumor characteristics, multivariable analysis controlling for patient characteristics demonstrated that RN was associated with an increased risk of complications, OR 1.42 (95% CI 1.35-1.49). CONCLUSION: Here, we report an 8.9% increase in the proportion of patients undergoing PN between 2010 and 2018, with no associated increase in perioperative morbidity/mortality. Given that there was no concurrent shift in stage or size of kidney tumors undergoing resection during the study period, these data therefore suggest markedly improved surgical technique and perioperative management nationally. Furthermore, the relative burden of complications has shifted from patients undergoing PN to those undergoing RN. Therefore PN, when technically feasible, should be increasingly considered.
