[Late metastases of prostatic adenocarcinoma to urinary bladder after radical prostatectomy: a case report]

Abstract

We report a case of metastasis of prostatic cancer to urinary bladder. A 67-year-old man was admitted with a complaint of macroscopic hematuria, who had undergone radical prostatectomy and surgical castration for prostatic cancer (pT3N0M0) 53 months before. Computed tomographic (CT) scan revealed an invasive tumor on the right wall of the urinary bladder and swelling of paraaortic and pelvic lymph node metastases. These lesions were diagnosed as bladder tumor with lymph node metastases, and then transurethral biopsy of bladder tumor was performed. Because macroscopic hematuria could not be controlled and severe progressive anemia was found after the biopsy, simple cystectomy and bilateral cutaneoureterostomy were performed on the next day. Histopathological analysis showed that the tumor was adenocarcinoma, which was thought to be a metastatic tumor from the prostatic cancer.
