National trends and disparities of minimally invasive surgery for localized renal cancer, 2010 to 2015.

Purpose: To investigate national utilization trends of minimally-invasive partial nephrectomy (PN) and minimally-invasive radical nephrectomy (RN), and to identify disparities in the usage of these techniques across different sociodemographic subgroups.

Materials And Methods: A retrospective cohort study was conducted using the National Cancer Database to identify patients undergoing partial or RN for cT1N0M0 renal cancer diagnosed between 2010 and 2015. Main outcomes of interest were the utilizations of minimally-invasive (robotic and laparoscopic) PN and RN.

Obesity and 30-Day Outcomes Following Minimally Invasive Nephrectomy.

Objective: To evaluate the association between obesity and postoperative outcomes following minimally invasive partial nephrectomy (MIPN) and minimally invasive radical nephrectomy (MIRN).

Methods: Using the National Surgical Quality Improvement Project database, we identified adult patients who underwent either MIPN or MIRN from 2012 to 2016. Patients were stratified by body mass index (BMI) according the World Health Organization classification of obesity (nonobese [BMI 18.
