Colonic neoplasms complicating ureterosigmoidostomy.

A Lasser, A E Acosta

    Cancer
    |April 1, 1975
    PubMed
    Summary

    Benign polyps developed at ureteral implantation sites years after ureterosigmoidostomy for bladder exstrophy. Long-term surveillance is crucial for patients who underwent this surgery due to potential tumor development.

    Area of Science:

    • Urology
    • Colorectal Surgery
    • Oncology

    Background:

    • Bilateral ureterosigmoidostomy is a surgical procedure for bladder exstrophy.
    • Complications can arise at the ureterocolic anastomosis site years post-surgery.

    Purpose of the Study:

    • To report a case of benign reactive polyps at ureteral implantation sites.
    • To review literature on neoplasms complicating ureterosigmoidostomy.

    Main Methods:

    • Case report of polyp development.
    • Comprehensive literature review on ureterosigmoidostomy-associated neoplasms.

    Main Results:

    • Two benign reactive polyps found at ureteral implantation sites 23 and 27 years post-ureterosigmoidostomy.
    • Polyps contained benign cystic glandular epithelium, resembling colitis cystica profunda but confined to the polyps.
    • Literature review identified potential for benign or malignant colonic tumors at the anastomosis site.

    Conclusions:

    • Benign polyps can develop at ureteral implantation sites years after ureterosigmoidostomy.
    • Patients require lifelong monitoring for potential colonic tumor development at the ureterocolic anastomosis.
