Summary
The laser-assisted fluoroscopic puncture technique (LAFPT) improves kidney access accuracy. This method reduces radiation exposure during procedures, offering a safer alternative to conventional fluoroscopic access.
Area of Science:
- Medical Imaging
- Interventional Radiology
- Surgical Technology
Background:
- Fluoroscopic guidance is crucial for minimally invasive procedures.
- Accurate needle placement is essential for successful kidney access.
- Reducing radiation exposure during fluoroscopy is a significant clinical goal.
Purpose of the Study:
- To introduce and evaluate the laser-assisted fluoroscopic puncture technique (LAFPT) for kidney access.
- To compare the efficacy of LAFPT against conventional fluoroscopic access methods.
- To assess the impact of LAFPT on procedure time and radiation exposure.
Main Methods:
- A novel laser pointer device was integrated with a C-arm fluoroscope.
- The LAFPT was tested in an in vitro model using Foley balloons and silicone pads.
- Clinical cases were used to compare LAFPT with conventional fluoroscopic access.
- Key metrics included number of attempts and total fluoroscopy time.
Main Results:
- In vitro, LAFPT required significantly fewer attempts for puncturing 2-mL balloons compared to conventional methods.
- In vitro fluoroscopy time was reduced by 50% using LAFPT.
- No statistically significant difference in procedure time was observed between LAFPT and conventional techniques in the clinical series.
Conclusions:
- The laser-assisted fluoroscopic puncture technique facilitates precise needle positioning.
- LAFPT offers a potential reduction in radiation exposure for patients and staff.
- This technique presents a viable alternative for kidney access procedures.
