Purpose:
To report our experience and evaluate the efficacy and safety of real-time ultrasonography-guided percutaneous nephrolithotomy (PCNL) using SonixGPS navigation in patients with kidney stones.
Materials And Methods:
From December 2012 to May 2013 in our hospital, the SonixGPS needle tracking system was used for real-time ultrasonography-guided puncture during PCNL in 25 patients with kidney stones. All the patients were under general anesthesia, in prone position; holmium laser lithotripsy was used in all patients after renal access was established. The time needed to perform puncture and the success rate of PCNL were recorded as two most important outcomes of this study.
Results:
All 25 patients underwent PCNL successfully with the help of SonixGPS navigation. The mean puncture time was 5.5 minutes (range 3-9 min), and the mean operative time was 74 minutes (range 30-100 min), respectively. The primary stone clearance rate of PCNL was 92% (23/25); no major intraoperative or postoperative complications occurred.
Conclusion:
The results of this study indicate that puncture under SonixGPS navigation is safe and efficacious in PCNL, which may provides a new choice for PCNL.
