title: [Port-Site Metastasis of Urothelial Carcinoma after Laparoscopic Nephroureterectomy: A Case Report].
abstract: The patient was a 70-year-old woman with a chief complaint of right hydronephrosis and hydroureter detected by ultrasound by a local doctor. She came to our hospital in January, 2014 for further examination. Because a tumor was discovered in her right upper ureter by computed tomography (CT) and retrograde pyelography, a right laparoscopic nephroureterectomy was perfomed on the suspicion of a right ureter carcinoma (clinical stage T2 N0M0). The pathological examination showed urothelial carcinoma, grade 3, pT3. She was followed up carefully without adjuvant chemotherapy. At 10 months postoperatively, a subcutaneous tumor was found at the port-site by CT, and she underwent surgical resection of the subcutaneous tumor. Pathological diagnosis was urothelial carcinoma, and was confimed to be portsite metastasis of urothelial carcinoma. She received three courses of gemcitabine and carboplatin chemotherapy therapy from November, 2014. She has been followed up without signs of recurrence.
