Ultrasonography accurately measured prostate volumetric changes in benign prostatic hypertrophy (BPH) patients. However, the technique showed poor diagnostic accuracy for malignant prostates and calculi detection.

Area of Science:

Urology
Medical Imaging
Diagnostic Technology

Background:

Transrectal ultrasonography is utilized for prostate imaging.
Accurate measurement of prostate volumetric changes is crucial for treatment assessment.

Purpose of the Study:

To assess the accuracy of ultrasonographic measurement of prostate volumetric changes.
To compare ultrasonically calculated weight change with actual resected tissue weight post-TURP in BPH patients.

Main Methods:

A hand-held transrectal ultrasound probe was used.
Ultrasonic measurements were compared with the measured weight of resected prostatic tissue in 30 BPH patients.

Main Results:

A high correlation (r = 0.978) was observed between ultrasonographic and measured weights in BPH.

Difficulties were noted in applying the method to malignant prostates.

Ultrasound detected calculi in 60% and suspicious malignant tissue in 23% of benign cases.

Conclusions:

Ultrasonography demonstrates high accuracy for volumetric changes in benign prostatic hypertrophy.
The technique shows limitations for diagnosing malignant prostate conditions and detecting calculi.
Further research is needed to improve diagnostic accuracy for complex prostate cases.
