Abstract: 【Abstract】〓Objective〓To explore the clinical value and safety of local anesthesia combined CT 3D reconstruction in the second phase of percutaneous nephrolithotomy. Methods〓Between January 2012 and November 2015, 64 cases of patients with residual stone after PCNL were selected, and analyzed by CT 3D reconstruction, and second phase of PCNL was performed under local anesthesia. The stone clearance rate, security and pain degree were assessed. Results〓Of 64 cases undergoing PCNL, the residual renal stones were removed completely in 60 cases (93.8%), and 4 cases failed and the size of residual stones were less than 4.0 mm. Post-operative pain score included 54 cases in 0 to 3 points (84.4%), 7 cases in 4 to 6 points of (10.9%), and 3 cases in 7 to 9 points(4.7%). No one was transferred to general anesthesia for operation due to unbearable pain or needed open surgery. No serious complications occurred in all patients. The hemoglobin level, renal function and serum electrolytes had not changed obviously. Conclusion〓Management of local anesthesia combined CT three dimensional reconstruction was safe to treating remove residual calculi in the second phase of PCNL.
