抄録: | Ureteral metastases from prostate cancer are uncommon. We report a case of prostate cancer with bilateral ureteral metastases. A 76-year-old man visited our hospital because of serum prostate specific antigen (PSA) level of 40.7 ng/ml. Contrast-enhanced computed tomography revealed bilateral ureteral tumors causing bilateral hydronephrosis. Magnetic resonance imaging and prostate biopsy showed prostate cancer involving the bladder neck with bone metastases. Voided urine cytology suggested urothelial carcinoma. Retrograde pyelography demonstrated left ureteral filling defect and right lower ureteral stenosis. Left ureteral tumor and concomitant prostate cancer were suspected ; thus, combined androgen blockade therapy was initiated, and left nephroureterectomy was subsequently performed. Pathological and immunohistochemical examination of the left ureteral tumor revealed PSA-positive adenocarcinoma. The contralateral ureteral lesion was presumed to be metastasis from the same origin ; hence, prostate cancer with bilateral ureteral metastases was diagnosed. Although the mechanism is unknown, ureteral metastasis should be considered in the differential diagnosis of prostate cancer patients with ureteral tumor. |
