Methods： We retrospective analyzed the data of 345 patients who underwent rigid ureteroscopic lithotripsy in Department of Urology, Ninth Affiliated Hospital of Guangxi Medical University between January 2003 to January 2011. These data included 44 cases of difficulty passing instruments which were managed successfully with proper strategies. The causes and experiences with the management in these cases were summarized. Results ： Among 44 cases, the instruments were successfully passed into the urinary tract with rotation techniques in 17 patients, modification of patient position plus fascial dilation of ureter in 16, vaporization and resection of distal ureter in 2, and incision of ureteral stricture in 4. Two cases were converted to open surgery, and 5 to ESWL with indwelling of ureter catheter. Conclusion： Good knowledge of ureteral anatomy and pathophysiology, excellent manipulation skills, and experiences of the surgeon are critical to successful passing of instruments during ureteroseopy.
