Abstract
In most cases, prostate cancer metastasizes to the lymph nodes, bone, and liver. In very rare cases, it metastasizes to the ureter. Due to the difficulty in making a preoperative diagnosis, ureteral metastasis from prostate cancer is typically diagnosed after nephroureterectomy. A 77-year-old Asian Japanese man with right hydronephrosis and hydroureter was referred to our hospital to undergo further examination due to the suspicion of ureteral cancer. He had been diagnosed 2 years previously with prostate cancer with a Gleason score of 4+5=9. He received radiotherapy and androgen deprivation therapy. A nephroureterectomy was performed for suspected right ureteral cancer. On the basis of a histopathological examination, poorly differentiated adenocarcinoma was suspected, and the tumor cells were positive for prostate-specific antigen immunohistochemically. We herein report a rare case of ureteral metastasis in castration resistant prostate cancer.Keywords
