A Preliminary Report on the Safety and Efficacy of a Novel CT-Guided Puncture Device for Adult Percutaneous Nephrolithotomy

OBJECTIVE: A new type of CT-guided puncture device (CT-GPD) has been developed. We aimed to evaluate and compare the puncture accuracy and stone-free rates (SFRs) for percutaneous nephrolithotomy (PCNL) between the CT-GPD puncture group, the X-ray-guided group, and the free-hand CT-guided (FH-CTG) group. METHODS: From September 2023 to September 2024, 51 patients were divided into CT-GPD, FH-CTG, and X-ray-guided groups to perform PCNL. Basic patient data, procedure details, radiation exposure, puncture time, complications, and SFRs were recorded and analyzed. RESULTS: = 0.006), respectively. CONCLUSION: CT-GPD is a valuable tool for establishing PCNL access. It may increase puncture accuracy, reduce radiation exposure, and avoid injury to the renal vascular and surrounding soft tissue without sacrificing the SFRs. This device may be especially beneficial for novices in PCNL.
