The case of a 69-year-old man who underwent radical prostatectomy because of carcinoma of the prostate is reported. A preoperative cystoscopy was normal. The histological evaluation of the radical prostatectomy showed an infiltration of the urethral margin. 14 months later, cystoscopy showed papillary metastases of the prostatic carcinoma in the bladder. Immunohistochemistry and flow cytometry for various prognostic factors showed a high malignant potential of this tumor. Preoperative transurethral instrumentation for the treatment of urethral strictures may be responsible for the dissemination of tumor cells into the bladder.
报告了一例69岁因前列腺癌接受根治性前列腺切除术的男性病例。术前膀胱镜检查正常。根治性前列腺切除术的组织学评估显示尿道边缘有浸润。14个月后，膀胱镜检查显示膀胱癌有乳头状转移。针对各种预后因素的免疫组织化学和流式细胞术显示该肿瘤具有高恶性潜能。术前经尿道器械操作治疗尿道狭窄可能是肿瘤细胞播散至膀胱的原因。
