[A case of metastatic ureteral tumor].

We report a case of metastatic ureteral tumor resulting from gastric cancer in a 56-year-old female. She had undergone distal gastrectomy for gastric cancer in our hospital 3 years earlier, on the histological diagnosis of poorly differentiated adenocarcinoma with absolute curative resection. In March, 1987, she visited our hospital complaining of microscopic hematuria and lumbago. Intravenous pyelography and left retrograde pyelography revealed the stenotic change of the left ureter and hydronephrosis. Endoscopic ureteral biopsy was performed, and the histological diagnosis was an inflammatory change of the ureter. But the hydronephrosis increased, so partial ureterectomy was performed. The histological examination confirmed adenocarcinoma in the left ureter resulting from gastric cancer. From the 340th postoperative day, she complained of general fatigue and vomiting, and gastroscopy revealed recurrent gastric cancer.
