This paper reports a 73-year-old man who developed ureteral squamous metaplasia. Preoperative drip infusion pyelography showed a ureteral tumor with a major axis measuring 2.5 cm, which had a smooth surface and a broad base. Computed tomography findings suggested that the lesion might be a submucous mesodermal tumor or inverted papillary transitional cell carcinoma. Therefore, retroperitoneal laparoscopic left nephroureterectomy was performed.
