Colonoscopy with biopsy was included in the surveillance of 19 patients with ureterosigmoidostomy, because of the high incidence of colonic carcinoma reported in such cases. The patients were examined 1-6 times, at intervals of 1-2 years, 4-36 years after the urinary diversion. Random biopsies from the distal colon and rectum showed only discrete changes, and no dysplasia. Polyps with dysplastic changes were found close to ureteral anastomoses in three patients. For routine check-up of the rectosigmoid region and the ureteral implantation sites, examination with a flexible sigmoidoscope seems to be adequate and preferable, giving easy access to the risk zone for the development of cancer. Caution should be exercised, however, when performing biopsy close to the ureteral orifices.
由于输尿管乙状结肠吻合术患者结肠癌发病率较高，19例输尿管乙状结肠吻合术患者的监测中纳入了结肠镜检查及活检。这些患者在尿路改道后1至6次接受检查，间隔1至2年，时间为4至36年。远端结肠和直肠的随机活检仅显示散在性改变，无发育异常。3例患者在输尿管吻合口附近发现有发育异常改变的息肉。对于直肠乙状结肠区域和输尿管植入部位的常规检查，使用乙状结肠镜检查似乎足够且更可取，因为它能轻松进入癌症发生的危险区域。然而，在输尿管口附近进行活检时应谨慎。
