Acute Kidney Injury due to Povidone-Iodine

Abstract

Povidone-iodine is a broad-spectrum antiseptic applied topically to treat wounds and prevent their infection. Despite the apparent innocuousness of this agent, several cases of acute kidney injury (AKI) due to iodine toxicity have been reported. We report a case of severe AKI that occurred in a 32-year-old female three days after a hysteroscopy for the diagnosis of primary sterility using povidone-iodine as the local antiseptic agent. We made a clinical diagnosis of tubular necrosis related to iodine toxicity in view of the clinical presentation and high blood iodine concentration. The patient was treated with hemodialysis until urine output and renal function improved. Physicians must be aware of the possible nephrotoxicity secondary to povidone-iodine use. Patients receiving povidone-iodine, especially those who already suffer from kidney failure, should be closely monitored. The discontinuation of this agent, with the use of hemodialysis, is usually effective.
