Abstract
Complications of Double J stenting (DJS) include migration, fragmentation, and encrustation. In addition, forgotten stents with encrustations and stone formations are difficult to remove. We report the case of a stent "forgotten" for 10 years, concomitant with multiple ureteral stones and bladder calculus. Whole encrustation of the stent was observed. The patient underwent cystolithotripsy, ureteroscopic laser lithotripsy and stent removal. We report the longest period of forgotten DJS with maximum stone burden in the urinary system. To avoid this situation, patients should be educated regarding complications if the stent is not removed within a short period.
