Figure 2 (A-C): Under ultrasonography guidance, the upper pole was punctured with micropuncture needle followed by contrast injection under fluoroscopy (A). After contrast injection, the upper end of the impacted stent could be seen in the middle calyx whereas lower end could be seen in the urinary bladder. Under fluoroscopic guidance, the impacted stent was gradually pushed into the urinary bladder by an Amplatz super stiff guide wire introduced through the MPA catheter (B). Subsequently, cystoscopy was performed and the stent was successfully removed. Anterograde pyelography (C) with nephrostomy tube in situ showing the opacification of pelvicalyceal system and ureter without any filling defect
