Assisted extraction using extracorporeal lithotripsy of the calcified ureteral catheter overlooked for 2 years

A 45 year old man with a 2 year forgotten left double-pigtail ureteric stent was referred to our hospital. Because of distal calcifications, the stent could not be removed by means of a cystoscopy. So, extracorporeal wave lithotripsies were performed and then the stent were easily removed in two fragments by cystoscopy and ureteroscopy.
