ABSTRACT

Prostate cancer is a common malignancy in men, but rarely metastases to the ureter. A 68-year-old patient with ureteral metastases of prostate cancer was admitted to the hospital due to left lumbar and abdominal pain one month. Enhanced CT examination of urinary system after admission mass in the middle of left ureter; multiple enlarged pelvic, retroperitoneal and left groin lymph nodes. After admission, the patient's PSA was 69.4 ng/ml, a prostate transrectal needle biopsy showed acinar adenocarcinoma. Under ureteroscopy, a smooth hard mass was seen 15 cm from the left ureteral orifice and completely obstructed the left ureter, the biopsy pathology showed infiltration of heteromorphic cell mass, and tumor could not be excluded. Laparoscopic ureteral tumor resection + end to end ureteral anastomosis was planned and intraoperative freezing was performed to determine the nature of the tumor. Due to severe adhesion around the tumor, partial nephrectomy, ureter and cystectomy were performed. The postoperative pathological diagnosis was ureteral metastasis of prostate cancer. The patient was treated postoperatively with abiraterone and goseririn for prostate cancer. CT examination 6 months after surgery showed multiple pelvic and retroperitoneal lymph node enlargement disappeared.
