title: Pulmonary metastasis from urothelial carcinoma of the upper urinary tract 29 years after nephrectomy.
abstract: BACKGROUND
  Late pulmonary metastasis from urothelial carcinoma (UC) of the upper urinary tract is extremely rare.
  
  
  METHODS
  A 76-year-old man was referred to our hospital due to an abnormal shadow on chest X-ray. He had a history of left nephrectomy with a diagnosis of UC in the renal pelvis 29 years previously. Computed tomography showed a mass lesion in the right middle lobe of the lung that measured 4.9 cm in diameter. A transbronchial biopsy revealed the tumor to be metastatic pulmonary UC, and he underwent right middle lobectomy of the lung.
  
  
  CONCLUSIONS
  Long-term postoperative follow-up of patients with UC might be necessary after radical nephrectomy.
