Estimated GFR Decline Following Sodium Phosphate Enemas Versus Polyethylene Glycol for Screening Colonoscopy: A Retrospective Cohort Study

Use of sodium phosphate enemas versus PEG alone prior to colonoscopy screening increases the risk for VA patients having long-term eGFR decline. Patients with non-iron deficient anemia are at particularly high risk for eGFR decline. These findings motivate the need to re-examine prescribing practices for sodium phosphate enemas as part of a bowel-cleansing regimen.
