Forgotten Double J Ureteral Stent for 10 years: A Case Report with Review of Literature
2020
Background: Ureteral stents are a crucial part of urologic surgeries. Complications of Double J stenting
(DJS) include migration, fragmentation, and encrustation. In addition, forgotten stents with encrustations
and stone formations are difficult to remove.
Case Presentation: We report the case of a stent “forgotten” for 10 years, which migrated downward into
the proximal ureter, concomitant with multiple ureteral stones and bladder calculus. Whole encrustation of
the stent was observed. The “forgotten” stent was positioned 10 years ago during right ureteral stone
treatment in the Philippines. In the end, the patient underwent laser cystolithotripsy, stone elimination,
ureteroscopic laser lithotripsy and stent removal. The final X-ray post-intervention revealed the absence of
any stone fragment or residual DJS fragment.
Conclusion: 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. Moreover, a computerized registry of stent placement can be used to alert
the urologist when the stent ought to be removed.
