Renal failure induced by contrast material

T Robinson, K Waterhouse, J A Becker

    Urology

    Summary
    This summary is machine-generated.

    Parenterally administered iodinated contrast material can cause kidney failure, especially in diabetic patients with poor kidney function. High-risk individuals should avoid intravascular contrast examinations when possible to prevent contrast-induced nephropathy.

    Area of Science:

    • Nephrology
    • Radiology
    • Pharmacology

    Background:

    • Parenterally administered iodinated contrast material is a known cause of acute kidney injury.
    • Diabetes mellitus and pre-existing renal insufficiency are significant risk factors for contrast-induced nephropathy.

    Purpose of the Study:

    • To document the risk of renal failure from iodinated contrast material.
    • To identify high-risk patient populations for contrast-induced nephropathy.
    • To suggest alternative diagnostic methods for at-risk patients.

    Main Methods:

    • Review of documented cases of renal failure following contrast administration.
    • Identification and analysis of risk factors, including diabetes and creatinine levels.
    • Evaluation of alternative diagnostic modalities.

    Main Results:

    • Transitory and occasionally irreversible renal failure is well-documented.
    • Diabetes and pre-existing renal insufficiency are the most critical risk factors.
    • Patients with diabetes and creatinine levels >= 5 mg/dL are particularly high-risk.

    Conclusions:

    • Intravascular contrast examinations should be avoided in high-risk patients whenever feasible.
    • Alternative methods for evaluating renal failure or hematuria should be considered.
    • Risk stratification is crucial for preventing contrast-induced nephropathy.
