[Metastatic ureteral tumor from the digestive organ: a case report].
A 63-year-old woman admitted because of a right non-visualizing kidney. Right ureteral tumor was clinically diagnosed by routine examinations. Pathological finding after right nephroureterectomy and partial cystectomy revealed adenocarcinoma of the ureter. She also had a history of gastrectomy for gastric cancer 4 years before. Metastatic adenocarcinoma of the right ureter from the stomach was the final diagnosis made after the pathological comparison of the two specimens. Thirty nine cases of metastatic ureteral tumor from the digestive organs were reported in Japan. The autopsy suggests that metastatic ureteral tumors occur more often than we may expect and as metastatic and invasive ureteral tumors from digestive organ, are often confused, the criteria to distinguish between them must be established.
