A Severely Encrusted Forgotten Double J Ureteral Catheter.

Double J (DJ) stents provide efficient upper urinary system drainage in patients with ureteral obstruction [1]. Long-term indwelling DJ stents may be complicated by encrustation and stone formation. Patients should have their DJ stents replaced every three months [2]. Plain abdominal radiography and computed tomography are the imaging methods of choice in these patients for making a diagnosis and guiding the therapy.
