Sonometrics of the prostate.

G Bartsch, G Egender, H Hübscher

    The Journal of Urology
    |June 1, 1982
    PubMed
    Summary

    Sonometrics, combining transrectal sonography and biometrics, offers an accurate method for determining prostatic weight, surpassing traditional rectal exams. This technique correlates well with postoperative measurements and tracks age-dependent prostate growth.

    Area of Science:

    • Urology
    • Medical Imaging
    • Biometrics

    Background:

    • Rectal examination for prostatic size lacks accuracy and reproducibility.
    • Objective measurement of prostatic weight is crucial for clinical assessment and research.

    Purpose of the Study:

    • To introduce and validate Sonometrics, a novel method for determining prostatic weight.
    • To assess the correlation between sonometrically estimated prostatic weight and actual postoperative weight.
    • To evaluate the utility of Sonometrics in studying age-dependent prostatic growth and volume changes.

    Main Methods:

    • Sonometrics utilizes transrectal sonography combined with biometrics.
    • An optomanual image analyzing system (BIT PAD-TRS 80) was employed to measure prostate dimensions from sonographic images.
    • Prostate length, area, and circumference were calculated using computer analysis of traced images.

    Main Results:

    • A high correlation coefficient was observed when comparing sonometrically estimated prostatic weights with postoperative weights.
    • Age-dependent prostatic growth demonstrated an age-volume relationship consistent with established studies.
    • The method proved effective in assessing prostatic volume changes, even in small prostates, as seen in hypogonadism patients.

    Conclusions:

    • Sonometrics provides an accurate and reproducible method for determining prostatic weight.
    • This technique is valuable for clinical evaluation, surgical planning, and research into prostate physiology.
    • Sonometrics facilitates the assessment of prostatic volume changes across different age groups and clinical conditions.
