Sonometrics of the prostate

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.
