Contrast Nephropathy – The “Fake News” of Nephrology
The spectre of causing kidney damage has long hung over physicians deciding whether to give radiocontrast to often critically unwell patients. But is this concern justified? Has contrast induced nephrotoxicity been overblown? Have patients and physicians been denied crucial diagnostic information needlessly? Past and current evidence may suggest that radiocontrast is not the potent nephrotoxin dogma holds it to be. Previous risk estimates of contrast nephrotoxicity were likely significantly confounded by co-morbid illnesses. Even in the rare instances where is does occur, contrast nephrotoxicity is generally reversible and mild. Contrasted scans may yield life-saving diagnostic information. This presentation will review current literature on contrast nephrotoxicity, and discuss the renal safety, or otherwise, of contrast administration in the unwell and / or renally-impaired patient. Perhaps we will finally out the “fake news” of nephrology – contrast nephrotoxicity!
