April 2001. Another ureteral stent was inserted in addition to the encrusted ureteral stent (Figure 1).
(a) The body of the encrusted ureteral stent. (b) Flexible URS shows that the upper end of the encrusted ureteral stent was heavily calcified to the renal stone. (c), (d) Lithotripsy around the encrusted stent using Ho: YAG laser (ureteral stent: arrow).

A 6Fr rigid URS was inserted to the ureter beside the encrusted ureteral stent toward to the renal pelvis under guide wire assistance in order to observe the ureter and ureteral stent (Figure 2(a)). A 12 Fr ureteral access sheath (UAS) (Flexor, COOK Urological, USA) was inserted into the ureter beside the ureteral stent to observe the renal pelvis using a 5.3Fr flexible URS (URF-P5, Olympus, Japan) to determine the association of the ureteral stent and renal stone (Figure 2(b)). Intracorporeal lithotripsy was performed to control the ureteral stent, around the encrusted stent using the Ho: YAG laser (using a 200 mum fiber, 1.0 J, 5 Hz; Versa Pulse 30 W, LUMENIS surgical, USA; Figures 2(c) and 2(d)).
