What are the outcomes of contrast

Fewer than one-third of patients develop some level of residual renal impairment. Patients who need dialysis have a worse prognosis, with 35.7% inhospital mortality reported (compared to 7.1% in the nondialysis cohort) and 2-year survival of only 19%.

How long does it take the kidneys to recover from contrast dye?

While in most cases CI-AKI is self-limiting and creatinine or estimated glomerular filtration rate (eGFR) return to baseline levels in 5–10 days, in patients with a high risk profile for kidney damage, CI-AKI is associated with increased rates of in-hospital and short-term outcomes.

How bad is contrast dye for kidneys?

But, sometimes the dye can cause serious problems in the kidneys. This is known as “contrast induced nephropathy (CIN).” About 1% to 3% of people who receive these special dyes develop changes in their kidney function. Anyone can get CIN, but those at the greatest risk have CKD.

Is CIN reversible?
