Local tumour destruction (LTD) is a recommended therapy alternative for localized T1 renal cell carcinoma (RCC) for patients unfit for surgery. We examined patterns of use and complication rates of LTD in a large population-based cohort. Overall, 5285 patients undergoing LTD for RCC were extracted from the Nationwide Inpatient Sample database from 2006 to 2010. We assessed patient and hospital characteristics, as well as postoperative complications using International Classification of Diseases, 9.sup.th Revision codes. The impact of patient and hospital characteristics on peri-interventional complications (overall or specific) was tested using univariable or multivariable logistic regression models. Most patients were male (61.2%), aged 70 years or older (50.3%) and most had two or more comorbidities (57.1%). Most LTDs were performed at urban (93.5%), teaching (57.7%) and low-volume (75.7%) hospitals. Overall complications were recorded in 15.4%. In multivariable analyses adjusted for clustering, overall complications occurred more frequently in older, sicker patients who were treated at low-volume hospitals (all p
