The aim of this study is to understand Previous studies of dialysis access have suggested an obesity paradox showing lower overall mortality rates in end-stage renal disease (ESRD) patients with obesity. The goal of this study was to review institutional data and to analyze the patency rates of dialysis access-related to obesity. This is a single-institution, retrospective chart review of ESRD patients who had creation of new dialysis access or intervention of pre-existing access from July 2011 to June 2016. Obese (body mass index ≥30 kg/m2) and control groups were compared with respect to primary patency (time from access creation to first failure without intervention) and secondary patency (time from creation to permanent failure). Additional analyses compared patency rates for both arteriovenous fistulas (AVFs) and arteriovenous grafts (AVGs). More than 1100 patients required access creation or intervention during the observed time. The preliminary Results of the 124 charts consist of 55 (44.4%) patients with obesity.
