[Echomorphology of the prostate].

B Frentzel-Beyme, D Ledwa

    Ultraschall in Der Medizin (Stuttgart, Germany : 1980)

    Summary

    Transrectal sonography can detect prostate cancer and hyperplasia by analyzing echogenic structures. While 52% of carcinomas share echodensity with hyperplasia, diagnosis remains possible through additional criteria.

    Area of Science:

    • Urology
    • Medical Imaging
    • Pathology

    Context:

    • Analysis of 1983 transrectal sonographies of the prostate.
    • Correlation of sonographic findings with morphological structures from 93 dissected prostates.

    Purpose:

    • To evaluate the diagnostic value of transrectal sonography in identifying prostate cancer and hyperplasia.
    • To correlate echogenic structures observed in sonography with the actual morphology of the prostate gland.

    Summary:

    • Hyperplastic nodules typically exhibit similar or slightly increased echodensity compared to normal prostate tissue.
    • Prostate carcinomas can present with similar echodensity to diffuse hyperplasia in 52% of cases, necessitating further diagnostic criteria.
    • Transrectal sonography detected carcinomas in 87% of cases, with 18% differentiated by poor echogenicity.

    Impact:

    • Provides insights into the diagnostic capabilities and limitations of transrectal sonography for prostate evaluations.
    • Highlights the importance of correlating sonographic findings with morphological data for accurate diagnosis.
    • Contributes to understanding the echogenic characteristics of benign prostatic hyperplasia and prostate cancer.
