case_images: Ultrasonic lithotripsy (CyberWand, Olympus) was first used for reduction of stone burden and to provide exposure of suture material (Fig. 2).
case_images: Application of tension on the suture material through nephroscopy enables ureteroscopic transection of the foreign body at the level of the urothelium and eliminates the foreign body from future urine exposure.

case_images: Two surgeons then worked in synchrony, using a grasping instrument through the nephroscope to apply tension to the permanent suture material and permit transection through holmium: YAG laser lithotripsy at the level of the urothelium (Fig. 3).
