[Port-Site Metastasis of Urothelial Carcinoma after Laparoscopic Nephroureterectomy: A Case Report].

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.
