Summary
Personalized 3D-printed surgical guides (SG) improve percutaneous nephrolithotomy (PNL) by ensuring fast, precise needle access to the renal collecting system. This technique aims to reduce procedure time and complications associated with needle puncture.
Area of Science:
- Urology
- Medical Engineering
- 3D Printing in Medicine
Background:
- Percutaneous nephrolithotomy (PNL) is crucial for large kidney stones but has a 25% complication rate, partly due to needle puncture during tract preparation.
- Advancements in imaging and 3D visualization aid PNL, yet precise and rapid nephrostomy tract establishment remains challenging.
Observation:
- A novel approach utilizes personalized 3D-printed surgical guides (SG) to facilitate PNL.
- The workflow involves CT imaging, data segmentation, safe needle path planning, SG design, and manufacturing.
Findings:
- The 3D-printed SG enables fast and precise needle access to the renal collecting system during PNL.
- This method streamlines the nephrostomy tract creation process.
Implications:
- The integration of 3D-printed guides offers a cost-efficient solution to shorten PNL procedure times.
- This technique has the potential to significantly decrease complication rates related to needle puncture in PNL.
