Summary
Benign prostatic hyperplasia (BPH) anatomical features like intravesical prostatic protrusion increase with age and larger prostate volume. Three-dimensional (3D) imaging reveals significant changes in BPH, aiding research.
Area of Science:
- Urology
- Medical Imaging
- Anatomy
Background:
- Benign prostatic hyperplasia (BPH) anatomical characteristics, particularly intravesical prostatic protrusion (IPP), remain understudied.
- Investigating the influence of age and prostate volume on BPH anatomy is crucial for understanding disease progression.
Purpose of the Study:
- To determine the effects of patient age and prostate volume on the anatomical features of benign prostatic hyperplasia (BPH).
- To utilize three-dimensional (3D) measurement techniques for detailed analysis of BPH-related anatomical changes.
Main Methods:
- Retrospective analysis of 98 patients diagnosed with benign prostatic hyperplasia (BPH).
- Reconstruction of 3D models from pelvic T2-weighted MRI scans, including prostate, central gland, peripheral zone, IPP, and prostatic urethra.
- Measurement of various volumetric and dimensional parameters, including IPP volume, thickness, index, prostate volume, and peripheral zone characteristics.
Main Results:
- Higher intravesical prostatic protrusion (IPP) volume, IPP thickness, and peripheral zone volume were observed in patients with prostate volume >80 mL compared to those with <80 mL (P<0.001, 0.01, 0.01).
- These parameters, along with IPP volume and thickness, significantly increased with age (P<0.001, 0.01, 0.05).
- Peripheral zone index decreased with age (P<0.01) and was lower in larger prostates (P<0.05), while IPP index, peripheral zone thickness, and prostatic urethra thickness showed no significant group differences.
Conclusions:
- The study highlights that intravesical prostatic protrusion (IPP) volume and thickness are significantly influenced by prostate size and patient age.
- Three-dimensional (3D) imaging and measurement provide valuable insights into the anatomical alterations associated with benign prostatic hyperplasia (BPH).
- The findings support the utility of 3D measurements for advancing clinical and scientific research in BPH.
