Risk of Impaired Renal Function After Colonoscopy: A Cohort Study in Patients Receiving Either Oral Sodium Phosphate or Polyethylene Glycol

Abstract

In patients without preexisting renal disease, the risk of renal impairment after colonoscopy appears to be similar between sodium phosphate and PEG users. Sodium phosphate use in patients with preexisting renal disease is not recommended, but common in clinical practice. Sodium phosphate should not be used in patients with preexisting serious renal disease, adequate hydration should be assured in all patients, and renal function should be monitored before and after colonoscopy in those at risk of renal dysfunction.
