Summary
A novel transperineal ultrasound-guided prostate rebiopsy technique offers systematic gland mapping. This method improves disease localization and aids in treatment planning for prostate cancer patients.
Area of Science:
- Urology
- Oncology
- Medical Imaging
Background:
- Accurate prostate cancer diagnosis and staging are crucial for effective treatment.
- Standard prostate biopsy methods may have limitations in comprehensive gland mapping.
- Repeat biopsies are often necessary for accurate disease assessment.
Purpose of the Study:
- To describe a new transperineal ultrasound-guided prostate rebiopsy method.
- To evaluate its effectiveness in systematic prostate gland mapping.
- To highlight its advantages for diagnosis and treatment planning.
Main Methods:
- Utilizes a fixed grid approach for biopsies.
- Employs special cylindrical cutting needles for variable core lengths.
- Integrates grid coordinates for precise histological examination and topographic reconstruction.
Main Results:
- Achieved more accurate and systematic prostate gland mapping compared to standard sector biopsies.
- Enabled detailed topographic reconstruction of disease lesions.
- Provided repeatable biopsy plans for comparison with previous procedures.
Conclusions:
- The described rebiopsy method enhances spatial localization of diseased tissue.
- Offers precise information on disease distribution within the prostate gland.
- Facilitates improved diagnosis, treatment selection, and monitoring of prostate cancer.
