[A case of sigmoid colon cancer that spread to the urinary bladder via the ureter].
A 69-year-old male was admitted to the hospital with the chief complaint of left hydronephrosis and diagnosed. A year ago, he underwent sidmoidectomy to cure sigmoid colon cancer diagnosed as stage IV. Ultrasonography (US) and computed tomography (CT) detected the compression of the ureter at its middle left due to the enlargement of the left iliac lymph node and hydronephrosis and hydroureter at the proximal to the compressed part. Then, a ureteral tumor was suspected and urinary cytology was class V. Cystoscopy detected a papillary tumor projecting from the left ureteral orifice. Because the histopathological manifestation by transurethral resection of bladder tumor and that by the sidmoidectomy were consistent, it was considered that sigmoid colon cancer spread to the urinary bladder via the left ureter. There have been only 4 reported cases of adenocarcinoma that multiplied in the ureter, and this is the fifth case report.
