AUA 2017: Robot-Assisted Percutaneous Nephrolithotomy – Using Technology For Easier Percutaneous Access
The GUI software is able to register and integrate images from fluoroscopic C-arm on the table. Specifically, the GUI was able to detect the needle location in real-time and respond to changes in trajectory with respect to multi-planer direction on X-ray. The authors tested the robot prototype first in a gelatin model and then moved onto trials in a live pig. Interestingly, the authors did a head to head study comparing free-hand technique versus robotic technique.
The robotic technique resulted in less radiation dose. The total duration of procedure and puncture time were increased as the robotic system needed time to complete alignment, however this was not statistically significant. Of note, during the robotic puncture the pigs breath was held as this was required for successful puncture.
Based on their results, the authors concluded that robotic renal puncture for nephrolithotomy may help surgeons feel more confident and shorten the learning curve for percutaneous access. This innovative Smart Robotic System (GUI) may allow for more widespread adoption of urologists gaining their own access during PCNL.
