Wooden Foreign Body in the Renal Pelvis.
Migration of foreign bodies into the renal collecting system is very rare and usually concerns iatrogenically implanted objects. Migration of a foreign body from the gastrointestinal tract to the kidneys is even more rare. We present a case of migration of a wooden toothpick from the duodenum into the pelvis of the right kidney. The patient was not aware that he swallowed a toothpick; the foreign body resulted in hematuria and flank pain. The toothpick was missed during the initial computed tomography urography. Correct diagnosis was revealed by follow-up computed tomography. The toothpick was extracted endoscopically.
