Extravasation in ureteral tumours.

S Ali Khan, K N Hu, A Baum

    International Urology and Nephrology
    |January 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Extravasation of contrast medium during retrograde pyelography is uncommon in ureteral tumors. This case highlights a rare instance of contrast extravasation caused by extensive ureteral invasion from a primary tumor.

    Area of Science:

    • Urology
    • Radiology
    • Oncology

    Background:

    • Contrast medium extravasation during retrograde pyelography can result from high injection pressure, catheter manipulation trauma, or pre-existing ureteral conditions.
    • While known complications, extravasation specifically within a ureteral tumor is exceptionally rare.

    Observation:

    • This report details a unique case where contrast medium extravasation was observed during retrograde pyelography.
    • The extravasation was directly attributed to extensive invasion of the ureter by a primary ureteral tumor.

    Findings:

    • The study identifies a rare association between primary ureteral tumors and contrast medium extravasation during retrograde pyelography.
    • Extensive tumor invasion into the ureter was the identified cause of the observed extravasation.

    Implications:

    • This case expands the understanding of potential complications during retrograde pyelography in the presence of ureteral malignancies.
    • It underscores the importance of considering tumor invasion as a cause for contrast extravasation in specific clinical scenarios.
    • Further investigation may be warranted to elucidate the mechanisms and frequency of this rare event.
