Patients who received a defunctioning ileostomy during surgery were compared with those who did not. Outcomes included chronic kidney failure, chronic kidney disease, acute kidney injury, and dehydration. Cox proportional hazards models were fitted for each outcome, using overlap weights derived from propensity scores for receiving a defunctioning ileostomy. Stoma reversal impact and mediation by anastomotic leakage were also examined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 5286 patients, 4623 (87%) received a defunctioning ileostomy and 663 (13%) did not.
