An exceptional migration of ureteral stent after antegrade placement: A case report.

We report an exceptional migration of ureteral stent in patient who underwent a robot-assisted laparoscopic right pyelotomy. After stone removal, an antegrade ureteral stenting (7-french; Double J) was performed without fluoroscopic control. A radiographic control was performed the next day and highlighted a migration into the cardiovascular system. The Double J was removed percutaneously through the right femoral vein under fluoroscopic guidance.
