Radiologic contrast-induced nephropathy (RCIRF) causes acute kidney injury after contrast media exposure, accounting for 10% of acute renal failure cases. Prevention strategies focus on hydration and identifying high-risk patients.

Area of Science:

  • Nephrology
  • Radiology
  • Toxicology

Background:

  • Radiologic contrast-induced nephropathy (RCIRF) is a significant cause of acute kidney injury.
  • It accounts for approximately 10% of all acute renal failure cases.
  • Pathogenesis involves contrast-mediated renal ischemia and direct tubular toxicity.

Purpose of the Study:

  • To summarize the understanding of RCIRF, including risk factors, diagnosis, and prevention.
  • To highlight the importance of identifying at-risk individuals.

Main Methods:

  • Literature review and synthesis of current knowledge on RCIRF.
  • Analysis of contributing factors and clinical presentation.
  • Evaluation of diagnostic criteria and preventive strategies.

Main Results:

  • Key risk factors include pre-existing renal insufficiency, diabetes, advanced age, volume depletion, and multiple myeloma.
  • Diagnosis is suspected based on acute renal dysfunction temporally related to contrast administration.
  • Prognosis for recovery is generally good.

Conclusions:

  • RCIRF is a multifactorial syndrome requiring careful patient selection and management.
  • Preventive measures are crucial, including adequate hydration and avoiding excessive contrast exposure.
  • Prophylactic therapy should be considered in selected high-risk patients.
