Summary
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.
