A 24-year-old woman had a rectal neoplasm which occurred 20 years after she had undergone ureterosigmoidostomy for exstrophy of the bladder. Only 41 cases of bening or malignant tumours of the large bowel developing after ureterosigmoidostomy have previously been reported in the literature. Adenocarcinoma of the colon is most frequently found and can develop even after urine has been diverted away from the colon. The presenting symptoms are either those of ureteral obstruction or of colorectal neoplasm. This rare complication remains intriguing and the possible pathogenetic mechanisms are discussed.
一名24岁女性患有直肠肿瘤，该肿瘤在她因膀胱外翻接受输尿管乙状结肠吻合术后20年出现。此前文献中仅报道过41例输尿管乙状结肠吻合术后发生的大肠良性或恶性肿瘤。最常发现的是结肠癌，即使尿液已从结肠改道，仍可能发生。出现的症状要么是输尿管梗阻的症状，要么是结直肠肿瘤的症状。这种罕见的并发症仍然很有趣，并对可能的发病机制进行了讨论。
