Three patients had carcinoma of the stomach, rectum, and lung, respectively, metastatic to the ureter in the absence of other known metastasis. Two of the three patients had abdominal pain, while the other patient had no upper urinary tract symptoms. All patients had excretory urograms that showed delayed or no excretion of contrast medium on the side of obstruction. Obstruction was confirmed with retrograde pyelography in each case. Two of three patients were treated with nephrectomy. Metastatic carcinoma of the ureter should be considered in patients with malignant disease with initial symptoms consistent with ureteral obstruction. The diagnosis may be suggested by pyelographic demonstration of an obstructed ureter. Symptomatic patients may require nephrectomy.

2 cases of metastasis to the ureter from carcinoma of the stomach are presented. The clinical and radiologic features are reviewed. Metastasis to the ureter is rare. A plea for vigorous evaluation and early detection of this entity is made.

Primary small cell neuroendocrine carcinoma of the upper urinary tract is a rare disease that is associated with a poor prognosis. An 81-year-old man was diagnosed with carcinoma of the stomach and underwent laparoscopic distal gastrectomy. Computed tomography (CT) revealed carcinoma of the left ureter and left hydronephrosis. The patient was diagnosed with carcinoma of the left ureter (cT2N0M0) and left laparoscopic radical nephroureterectomy was performed via a retroperitoneal approach. The pathological diagnosis was left ureter carcinoma (small cell neuroendocrine carcinoma, pT3). He was treated with four courses of the CE regimen (carboplatin area under the curve: 5, intravenously [IV] on day 1 and etoposide [80 mg/m2], IV on days 1-3). There is no evidence of disease at 21 months after radical nephroureterectomy.
