Purpose:
We developed a laser pointer device that is mounted on the image intensifier of a C-arm fluoroscope. The laser-assisted fluoroscopic puncture technique (LAFPT) is an alternative method of accessing the kidney.
Materials And Methods:
The LAFPT was assessed both in an in vitro model and in a series of cases. The in vitro model was composed of Foley balloons filled with contrast medium of different volumes (2-6 mL) embedded in silicone pads. The total fluoroscopy times and attempts required for a successful puncture with LAFPT were compared with those of conventional fluoroscopic access.
Results:
The number of attempts required to puncture the 2-mL balloons was significantly greater with the conventional fluoroscopic technique than with LAFPT. The fluoroscopy time in vitro was reduced 50% with LAFPT. However, there was no statistically significant difference in the time required for the two techniques in the clinical series.
Conclusion:
The laser-assisted fluoroscopic puncture technique allows accurate positioning of a needle with reduced radiation exposure.
