Incidence of postoperative acute kidney injury is higher in men than women after colorectal surgery – PROSACC: a posthoc analysis of a global, multicenter, randomized controlled trial

Abstract

Postoperative acute kidney injury (AKI) is a common postoperative complication. Approximately 7% of the general, elective, non-cardiac surgical population develop AKI after surgery. The female sex was previously believed to be associated with higher incidence of AKI however more recent literature implies that men have higher risk for AKI. Estrogen has been suggested to have renoprotective properties. We therefore aimed to analyze AKI incidence after colorectal cancer resection surgery in men and women on a global, multicenter, level.
