Ureteral ectopia in vestibule without urinary incontinence

T Koyanagi, S Hisajima, S Sakashita

    Urology
    |November 1, 1980
    PubMed
    Summary

    Two cases of ureteral ectopia opening in the vestibule were identified without urinary incontinence. This continence was likely due to the ectopic ureteral openings integrating into the urethral sphincter wall.

    Area of Science:

    • Urology
    • Pediatric Urology
    • Anatomy

    Background:

    • Ureteral ectopia is a congenital anomaly where ureters bypass the bladder.
    • It often presents with urinary incontinence, but variations exist.

    Observation:

    • Two pediatric patients presented with ureteral ectopia.
    • The ureteral openings were located in the vestibule, not the bladder.
    • Notably, both patients maintained urinary continence.

    Findings:

    • The ectopic ureters opened into the vaginal vestibule.
    • Urinary continence was preserved despite the abnormal ureteral placement.
    • Histological or functional integration of ureteral ends with the urethral sphincter is hypothesized.

    Implications:

    • This suggests that ureteral ectopia can present without incontinence under specific anatomical circumstances.
    • Understanding the sphincter's role in continence with ectopic ureters is crucial for surgical planning.
    • Further research into the anatomical variations of ureteral ectopia and continence mechanisms is warranted.
