Bilaterally small kidneys in shock

R W Katzberg, S T Schabel

    JAMA
    |May 17, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Acute kidney injury, or "shock kidneys," can cause temporary, bilateral small kidneys. This reversible response occurs during hypotensive episodes, showing a dense nephrogram on excretory urography.

    Area of Science:

    • Nephrology
    • Radiology
    • Physiology

    Background:

    • Acute kidney injury (AKI), also known as "shock kidneys," presents a diagnostic challenge.
    • Understanding the renal response during hypotensive episodes is crucial for patient management.

    Observation:

    • Three cases of
    • shock kidney
    • were evaluated using excretory urography.
    • Key imaging findings included a dense, prolonged nephrogram.
    • Reduced contrast material excretion was noted during hypotension.

    Findings:

    • The study observed bilaterally small kidneys in affected patients.
    • These renal size changes were present without evidence of chronic renal disease.
    • The observed findings are considered a normal physiological response to shock.

    Implications:

    • This study highlights specific excretory urography findings indicative of acute kidney injury.
    • It differentiates transient physiological responses from underlying chronic renal pathology.
    • Understanding these imaging patterns aids in accurate diagnosis and management of shock kidney.
