Comparison of outcomes after minimally invasive versus open partial nephrectomy with respect to trainee involvement utilizing the American College of Surgeons National Surgical Quality Improvement Program

Complication rates of open partial nephrectomies (OPN) and minimally invasive partial nephrectomies (MIPN) have largely been reported by single and multi-institutional tertiary care centers. We sought to identify complication rates of these approaches and how they are influenced by trainee involvement utilizing an independent national surgical database. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is a risk-adjusted data collection analyzing risk factors, demographics, and 30-day perioperative outcomes. From 2005 to 2010, we identified 1251 partial nephrectomies, of which 525 were MIPN and 726 were OPN. Analysis showed a decreased risk of overall morbidity, serious morbidity, and surgical site infections (SSIs); specifically superficial SSI, urinary tract infection, and bleeding (p
