Sonourethrography: technique for evaluation of prostatic urethra.

M D Rifkin

    Radiology
    |December 1, 1984
    PubMed
    Summary

    Transrectal sonoendoscopy visualizes the prostatic urethra during voiding, effectively detecting nodules and unsuspected carcinomas. This advanced imaging technique aids in diagnosing various urethral abnormalities.

    Area of Science:

    • Urology
    • Medical Imaging

    Background:

    • Prostate evaluation traditionally focuses on the gland itself.
    • Visualizing the prostatic urethra during functional states like voiding presents challenges.

    Purpose of the Study:

    • To extend transrectal sonoendoscopy to visualize the prostatic urethra during voiding.
    • To assess the technique's ability to detect urethral abnormalities.

    Main Methods:

    • Transrectal sonoendoscopy was adapted to include the prostatic urethra.
    • The urethra was visualized during the voiding phase.

    Main Results:

    • The technique clearly demonstrated the normal prostatic urethra.
    • Nodules impinging on and displacing the urethra were identified.
    • Clinically unsuspected carcinomas and other abnormalities were detected.

    Conclusions:

    • Transrectal sonoendoscopy is effective for visualizing the prostatic urethra during voiding.
    • This method aids in the diagnosis of urethral pathologies, including unsuspected malignancies.
