Intestinal conduits appear to have a low risk of malignancy. The increased risk of neoplasia after ureterosigmoidostomy is well known and may be multifactorial. Other forms of urinary reconstruction and diversion may also increase the risk of cancer. The reports of adenocarcinoma after ileocystoplasty are striking, as the intact ileum rarely undergoes malignant change. Long-term surveillance of patients after urinary reconstruction with intestinal segments is therefore mandatory.
肠道导管似乎发生恶性肿瘤的风险较低。输尿管乙状结肠吻合术后肿瘤形成风险增加是众所周知的，且可能是多因素导致的。其他形式的尿路重建和改道也可能增加癌症风险。回肠膀胱成形术后发生腺癌的报告令人震惊，因为完整的回肠很少发生恶性变化。因此，对接受肠道段尿路重建的患者进行长期监测是必不可少的。
