The patient was anesthetized with general or spinal anesthesia, and placed in lithotomy position. After cystoscopy, a hydrophilic guidewire (Roadrunner Wire Guide, Cook Medical, Bloomington, IN, USA) was inserted into the ureter. If pre-stenting was performed, using a ureteral stent, a hydrophilic guidewire was installed to the renal pelvis. A dual-lumen catheter was inserted through the hydrophilic guidewire, and retrograde pyelography was performed. Using the dual-lumen catheter, another guidewire (Amplatz Superstiff Guidewire; Boston Scientific, Marlborough, MA, USA) was inserted, and an 11/13 or 12/14 Fr ureteral access sheath (Uropass, Olympus) was inserted into the level of ureteropelvic junction. A flexible ureteroreno-videoscope was inserted through the ureteral access sheath. Lithotripsy was performed with a laser lithotripter (VersaPulse Powersuite 100W, Lumenis, Tel Aviv, Israel) and 200 micron laser fibers. Large fragmented stones were extracted using a 1.9 Fr (Zero-tip, Boston Scientific) or a 1.3 Fr (OptiFlex, Boston Scientific) nitinol stone basket. Dusted particles were not removed to allow for natural drainage. At the end of the procedure, fluoroscopy was performed to evaluate stone clearance. A 6 Fr ureteral stent (Polaris Ultra or Polaris Loop, Boston Scientific) was routinely placed and maintained for 1 to 2 weeks in all patients.
