A multivariate logistic regression analysis with variables including age, sex, pre\u2010existing comorbidities, tumor location, tumor\u2013nodes\u2013metastasis classification, academic status of hospitals, hospital volume, geographic region and year of surgery was modeled to evaluate predictors of carrying out a minimally invasive (including laparoscopic and minimum incision endoscopic) nephroureterectomy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 3863 open (58.2%), 2635 laparoscopic (39.7%) and 139 minimum incision endoscopic nephroureterectomy (2.1%) cases from 713 hospitals were identified.
