An Extremely Rare Complication of Ureteral Pigtail Stent Placement: A Case Report.

Double-J (DJ) stents are the main tools used in urological practice for prevention and treatment of obstruction. Stenting is also mandatory after complicated ureteroscopy or TUL (Transureteral Lithotripsy). Known complications are upper migration of DJ stents into the kidney and lower migration to the bladder. In a man with an impacted right lower ureteral stone, a DJ stent was placed because the ureteroscope was not passed from an intramural ureter. We reported a very rare complication of DJ ureteral stent placement with intravascular migration to the pulmonary arteries, which was removed percutaneously through the right femoral vein under fluoroscopic guidance.
