[Long survival in patient with invasive renal pelvic carcinoma treated with frequentative resection of pulmonary metastasis and chemotherapy: a case report].

A 51-year-old man was referred to our hospital for treatment of left renal pelvic tumor diagnosed with computed tomography (CT) on health screening. Retroperitoneoscopy-assisted radical left nephroureterectomy was performed under a diagnosis of left renal pelvic carcinoma. Histopathological examination showed urothelial carcinoma (UC), Grade 2 > > Grade 3, pT3. Subsequently to the radical operation, pulmonary metastasis appeared four times. But the patient with free of recurrence survives 6 years later, treated with chemotherapy and resection of pulmonary metastasis. Although the patient with high grade invasive renal pelvic carcinoma usually has a poor prognosis, it seems to be a possibility that if the lesion is resectable, resection of pulmonary metastasis carries a good prognosis.
