Abstract: 【Abstract】 Objective To compare the success rate and effectiveness of C-arm X-ray, B-convex array probe and probe B-guided percutaneous renal puncture. Methods A clinical data of 138 patients suffering from kidney stones and undergoing percutaneous nephrolithotomy lithotripsy were retrospectively analyzed. The patients were assigned to the X-ray-guided puncture group（n=46）, B ultrasound convex array probe-guided group （n=46） and B-ultrasound-guided puncture group （n=46） according to the different puncture methods to the kidneys. The success rate and effectiveness were compared between the three different methods of percutaneous puncture. Results All patients were successfully established a channel within the kidneys. One-time success rate of probe B-guided puncture group was 67.39%, ≤2 puncture success rate was 89.13%, and they were higher than that of either the B-convex array probe-guided puncture group or X-ray-guided puncture group. The differences were statistically significant（P<0.05）and the average number of puncture done by B-guided puncture probe was less than the other two groups. Forty-one（89.13%）of cases in the probe B-guided puncture group performed the procedure by calyx into the fornix and the puncture effectiveness was better than the other two groups （P<0.05）. Conclusion B-puncture probe used by the real-time guided percutaneous renal puncture shows better efficacy than X ray-guided, B-convex array probe-guided percutaneous renal puncture.
