ABSTRACT
Double-pigtail ureteral stent has been used to prevent the ureteral obstruction from calculi and to pass the urine easily after extracorporeal shock wave lithotripsy (ESWL). One of the complications in stent indwelling is the migration of the stent. Especially the proximal migration of double-pigtail ureteral stents is rare. One of the several theories that have been proposed to account for cephalad migration is a stent movement in conjunction with kidney movement during respiration. The reason is that the respiration makes the kidney move in both upward and downward directions while the stent, held by fragemented ureteral stone, moves only in upward direction. We call this cause of the proximal migration of the stent, 'Jack' phenomenon. Therefore, if the residual calculi remain after ESWL with ureteral stent, we need close observation.
