Abstract：Objective:To evaluate the clinical value of decapitating ureteral catheter in percutaneous nephrolithotomy (PCNL). Methods:A total of 126 cases including 73 males and 53 females underwent PCNL for upper urinary tract calculi. The mean age was 43.2 years, range 25 to 72. The calculi were found on left side in 65 cases, right side in 53, and both sides in 8. A decapitating ureteral catheter was inserted into the ureter with the guidance of a guide wire. A PCNL was performed in the prone position. Results:All the procedures were successful. There was no complication of the renal injury caused by the decapitating ureteral catheter. The mean operative time for was 60 (range 20 to 100) mins. The antegrade double J stents were directly placed in 74 patients. With the help of the guide wire inserted through the decapitating ureteral catheter, the renal pelvic orifices were found and the antegrade double J stents was successfully inserted in 20 patients, the antegrade double J stents were successfully placed in 21 patients, and the retrograde double J stents were successfully placed in 11 patients. Conclusions:The decapitating ureteral catheter appears to be safe and convenient for PCNL, which can help improve the success rate and reduce the operative time of PCNL. This technique is worthy of popularization and application in PCNL.
