Summary
Three-dimensional transrectal ultrasound effectively identifies and measures prostate zones, including the transition zone in benign prostatic hyperplasia (BPH). This advanced imaging aids in precise diagnosis and management of prostate conditions.
Area of Science:
- Urology
- Medical Imaging
- Radiology
Background:
- Accurate assessment of prostate zones is crucial for diagnosing and managing benign prostatic hyperplasia (BPH).
- Traditional imaging methods may have limitations in fully visualizing and quantifying prostate zonal anatomy.
Purpose of the Study:
- To evaluate the efficacy of three-dimensional transrectal ultrasound (3D-TRUS) in identifying and measuring prostate zones.
- To assess the utility of 3D-TRUS in differentiating prostatic structures in BPH and healthy young men.
Main Methods:
- An anatomic-sonographic study using eight specimens with 3D-TRUS, comparing measurements to anatomic sections and water displacement.
- Clinical evaluation of 90 BPH patients (55-85 years) and 10 healthy young men (17-30 years) using 3D-TRUS prior to biopsy.
Main Results:
- 3D-TRUS allows simultaneous visualization of prostate structures in sagittal, axial, and coronal planes.
- Structural differences between prostatic zones in BPH and juvenile glands are clearly identifiable.
- The coronal plane offers crucial information for identifying the central zone and enlarged transition zone in BPH.
Conclusions:
- 3D-TRUS clearly demonstrates prostate zones and their interrelations.
- Hyperplasia of the transition zone in BPH is well visualized.
- The size of the enlarged transition zone can be accurately measured using 3D-TRUS.
