Summary
Real-time transrectal ultrasound (TRUS) enhances laparoscopic radical prostatectomy (LRP) by improving visualization of critical anatomy. This guidance aids in precise dissection, potentially improving surgical outcomes.
Area of Science:
- Urology
- Surgical Technology
- Medical Imaging
Background:
- Laparoscopic radical prostatectomy (LRP) requires precise anatomical understanding for optimal outcomes.
- Transrectal ultrasound (TRUS) offers real-time imaging capabilities that can potentially aid surgical navigation.
Purpose of the Study:
- To describe the technical aspects of using real-time transrectal ultrasound (TRUS) for monitoring and guidance during laparoscopic radical prostatectomy (LRP).
- To detail the TRUS-visualized anatomy of periprostatic structures encountered during LRP.
Main Methods:
- 25 patients undergoing transperitoneal LRP had preoperative, intraoperative, and postoperative TRUS evaluations.
- TRUS measurements focused on the neurovascular bundle (NVB), prostate apex, membranous urethra, bladder neck, rectal wall, and cancer nodules.
- Utilized grayscale, power Doppler, harmonic imaging, and 3D ultrasound.
Main Results:
- Real-time TRUS facilitated identification of the plane between the bladder neck and prostate base, aiding seminal vesicle visualization.
- TRUS identified the prostate apex, enhancing apical dissection and margin control.
- TRUS visualized hypoechoic nodules, alerting surgeons to potential positive margins and guiding dissection.
- Measurements of NVB distance, dimensions, blood flow, and membranous urethra length were obtained.
Conclusions:
- Real-time intraoperative TRUS guidance appears to enhance the anatomical precision of LRP.
- Improved understanding of periprostatic anatomy through TRUS may lead to better functional and oncological results.
- Further studies are needed to corroborate these findings.
