    Summary
    This summary is machine-generated.

    Ensure Foley catheter balloons are visible on ultrasound. If not seen, search for the balloon to prevent potential trauma from incorrect placement within the urinary bladder.

    Area of Science:

    • Medical Imaging
    • Urology
    • Surgical Devices

    Background:

    • Foley catheters are common urinary drainage devices.
    • Ultrasound is frequently used to assess urinary bladder and surrounding structures.
    • Proper catheter balloon inflation is critical for function and patient safety.

    Observation:

    • The self-retaining Foley catheter balloon should be clearly visible during ultrasound of a distended urinary bladder.
    • Failure to visualize the balloon necessitates further investigation.

    Findings:

    • Extra-vesical inflation of the Foley catheter balloon can occur.
    • This malpositioning may lead to local tissue trauma.
    • It can also create misleading ultrasound images.

    Implications:

    • Radiologists and clinicians must be vigilant for Foley catheter balloon malpositioning.
    • Prompt identification of extra-vesical inflation is crucial to avoid complications.
    • Standardized ultrasound protocols should emphasize balloon visualization for Foley catheter placement verification.
