Ureteral stents are an integral part of urologic practices. Nonetheless, stents that migrate, fragment, or are forgotten pose management and legal dilemmas. We report the case of a "forgotten" stent, which migrated upward into the right renal pelvis, concomitant with a ureteral stone. The "forgotten" stent was placed 7 years previously during right ureteral stone treatment. The patient finally underwent nephroscopic stent retrieval and ureteroscopic ureteral stone removal. The final plain X-ray demonstrated no stone fragment or residual double J stent fragment. The patient withstood the procedure well and was free of symptoms thereafter.
