[Unrecognized ureteral duplication (author's transl)]

M Schmitt, J Prévot, L Martin

    Chirurgie Pediatrique
    |January 1, 1981
    PubMed
    Summary

    Recognizing occult ureters in duplex kidneys during surgery is crucial to prevent therapeutic errors. Early identification ensures proper management and avoids complications like renal failure.

    Area of Science:

    • Urology
    • Pediatric Surgery
    • Nephrology

    Background:

    • Duplex kidneys are a common congenital anomaly.
    • Occult ureters, particularly in duplex systems, can be challenging to identify.
    • Failure to recognize these anomalies can lead to significant therapeutic errors and patient harm.

    Observation:

    • The study reports four new cases involving five occult ureters in duplex kidneys.
    • These anomalies were identified during procedures for ureteral stenosis, acute renal failure, and vesicoureteral reflux.
    • In several cases, the upper ureteral pouch was blind or associated with dysplastic renal parenchyma.

    Findings:

    • Three of four observed lower ureteral pouches lacked an orifice, and one had an ectopic orifice.
    • Occult ureters share clinical similarities with ureteroceles, potentially leading to misdiagnosis.
    • Acute renal failure was a complication in one case diagnosed during a secondary procedure.

    Implications:

    • Intraoperative identification of occult ureters is vital, even without visualization of the intravesical orifice.
    • Ureteral opacification during surgical procedures can aid in discovering and managing these accessory ureters.
    • Timely diagnosis and appropriate management of occult ureters in duplex systems are essential for preserving renal function.
