Summary

Kidney stone is a common urological disease. Percutaneous nephrolithotomy (PCNL) is an important method for the treatment of kidney stones. The accuracy of puncture positioning affects the PCNL stone free rate and intraoperative/postoperative complications. Currently, PCNL puncture positioning methods are mainly X-ray-guided or ultrasound-guided. The main disadvantage of X-ray is the lack of soft tissue imaging, and the problem of low puncture accuracy. Although ultrasound is a commonly used real-time imaging tool, the image is not intuitive enough, and the puncture path is deviated from actual requirements . In order to improve the accuracy of PCNL puncture, this study intends to import CT images of both kidneys into a novel ultrasound machine through an image fusion system to achieve CT-ultrasound image fusion, and to simulate the puncture route to guide the PCNL puncture process. The study is mainly divided into two parts: (1) For patients with kidney stones who are planning to undergo PCNL, perform a preoperative simulated CT-ultrasound fusion examination to further clarify the condition of the kidney stones and simulate and optimize the puncture route; (2) Apply CT- Ultrasound fusion precise positioning to guide the intraoperative PCNL puncture process. On the basis of traditional ultrasound images, the CT-ultrasound fusion image display is added to provide the optimal puncture route to explore the effectiveness and safety of CT-ultrasound fusion precise positioning in PCNL puncture.
