[Gas in a pyelic calculus (author's transl)]

J Frija, R Tuil, M Katz

    Journal De Radiologie
    |January 1, 1982
    PubMed
    Summary

    A rare case of a gas-filled kidney stone (pyelic calculus) was observed. Researchers hypothesize gas formation via fissuration may lead to spontaneous stone dissolution, similar to gallstones.

    Area of Science:

    • Nephrology
    • Radiology
    • Urology

    Background:

    • Kidney stones (calculi) are common urinary tract stones.
    • Gas formation within calculi is an unusual phenomenon.
    • Computed tomography (CT) is a key imaging modality for calculus detection.

    Observation:

    • An original case report details a gas-containing pyelic calculus.
    • The calculus was radiolucent but visible due to gas content on CT.
    • Gas presence is attributed to fissuration within a crystalline calculus.

    Findings:

    • Spontaneous visibility of a gas-containing calculus via CT scan.
    • Hypothesis of gas formation as a fissuration process.
    • Potential for spontaneous calculus disappearance following gas apparition.

    Implications:

    • This finding may offer new insights into kidney stone pathogenesis.
    • Understanding gas formation could lead to novel non-invasive treatment strategies.
    • Further research is warranted to explore the link between fissuration, gas, and calculus dissolution.
