title: Fragment of a catheter as a foreign body in the kidney.
abstract: Foreign bodies in the kidney are unusual. A review of the literature disclosed few reports of renal foreign body from nontraumatic causes. In this article, we report a case of gross hematuria due to iatrogenic foreign body in the kidney from ureteral endoscopy. The catheter fragment eluded diagnosis for 18 months until it was discovered and retrieved by means of a flexible ureteroscope. To our knowledge, this is the first report of this complication and presentation following endoscopic manipulation of the upper ureteral tract.
