A case of solitary ureteral metastasis from cervical cancer in a 36-year-old female is reported. On April 4, 1988, the patient visited the gynecological department of our hospital with abnormal genital bleeding. Colposcopy and cervical biopsy revealed invasive cervical cancer, and computerized tomography (CT) indicated right hydronephrosis. She was referred to the urological department for further examinations. Right retrograde pyelography (RP) however could not be performed. On April 13, 1988, the patient underwent laparotomy due to acute abdomen, which was proved to be caused by subileus. On exploration, a tumor was found in the lower one third section of the right ureter, whereupon a right nephroureterectomy was performed because primary ureteral tumor was suspected. The histology of the ureteral tumor revealed it to be a metastatic squamous cell carcinoma identical to that obtained from punch biopsy of the cervix. At that time, a hysterectomy could not be done because of invasive cervical cancer. Following the operation, radiation therapy was conducted for primary cervical cancer. At present, 7 months after the operation, the patient is alive with good performance status.
