Acute kidney injury after colorectal surgery with prophylactic ureteral stents.

Background: After colorectal surgery, acute kidney injury (AKI) results from a complex interplay of multiple independent causes and preventive measures that occur during the hospitalization. Prophylactic stenting for ureter identification has been identified as a potential cause, but the evidence is conflicting, possibly because of differing baseline characteristics and procedure-related approaches.

Objective: This retrospective cohort study assesses the role of stents in the etiology of AKI after determining the independent predictors of AKI.
