The patient will then be repositioned to the prone position. Percutaneous renal access will be obtained by puncturing the selected calyx with an 18-gauge coaxial needle under fluoroscopic or ultrasound guidance. Tract dilation will be performed using fascial dilators up to 20 Fr then the mini-PCNL sheath (mini-Amplatz sheath) will be inserted and the mini nephroscope 12 to 15 Fr will be used. If multiple nephrostomy tracts are required for stone removal, the same approach will be repeated for each tract. Stone fragmentation will be carried out with a pneumatic lithotripter.\n\nAt the end of the procedure, a 6 Fr double-J ureteral stent will be inserted for 4 weeks, and whether to place a nephrostomy tube will be determined at the discretion of the operating surgeon.",[13],"Procedure: mini-percutaneous nephrolithotomy",{"label":15,"type":10,"description":16,"interventionNames":17},"FURS with Tip-Bendable Suction Sheath","under general anesthesia with the patient in the lithotomy position.

A guidewire will then be advanced into the renal pelvis. either a 12\u002F14 Fr or 11\u002F13 Fr tip-bendable S-UAS will be inserted. If insertion is not possible due to ureteral narrowing, a smaller 10\u002F12 Fr UAS will be attempted. if failed, a double-J stent will be placed and the procedure terminated, with a second session scheduled 4 weeks later. fURS will be performed using digital flexible ureteroscopes either 8.5 Fr or 7.5 Fr according to UAS size; an 8.5-Fr scope for a 12\u002F14 Fr UAS, and a 7.5-Fr scope for an 11\u002F13-Fr or 10\u002F12-Fr UAS.
