The development of colon carcinoma after ureterosigmoidostomy has not received adequate attention in the radiologic literature. Two patients who had ureterosigmoidostomy and subsequently developed tumors are described. The third case is a patient with a ureterosigmoidostomy and a ureterocele that simulated the appearance of carcinoma in the sigmoid colon. This is the first report of this entity. Ureterosigmoidostomy patients need frequent follow-up studies since their incidence of carcinoma is significant. The use of barium to study the colon in this group of patients is controversial. Barium can potentially reflux into the kidney with fecal material, which can lead to fibrosis and impaired renal function. However, barium reflux up the ureter is usually of no significance except on those rare occasions when intrarenal reflux occurs and inflammatory changes may develop. The diagnosis of tumors in these patients, diagnostic pitfalls, and controversy regarding use of barium enemas in following these patients are discussed.
输尿管乙状结肠吻合术后结肠癌的发生在放射学文献中未得到充分关注。本文描述了两名接受输尿管乙状结肠吻合术并随后发生肿瘤的患者。第三例是一名患有输尿管乙状结肠吻合术和输尿管囊肿的患者，其表现类似乙状结肠癌。这是该病例的首次报告。输尿管乙状结肠吻合术患者需要频繁进行随访研究，因为他们患癌的几率很高。在这组患者中使用钡剂研究结肠存在争议。钡剂可能会随粪便物质反流至肾脏，这可能导致纤维化和肾功能受损。然而，钡剂沿输尿管反流通常无显著意义，除非在极少数发生肾内反流并可能出现炎症变化的情况下。本文讨论了这些患者肿瘤的诊断、诊断陷阱以及在随访这些患者时使用钡剂灌肠的争议。
