    Summary

    Rare male urethra duplications are diverse and often asymptomatic. A new morphological classification system simplifies categorization, aiding in understanding these congenital anomalies.

    Area of Science:

    • Urology
    • Medical Embryology
    • Pediatric Surgery

    Background:

    • Urethral duplication is a rare congenital anomaly with limited documented cases.
    • Existing classification systems for urethral duplication are often complex or incomplete.
    • Understanding the embryological basis of urethral duplication remains challenging.

    Observation:

    • This study reviews 210 cases of male urethral duplication, noting significant variations.
    • Most urethral duplications are asymptomatic, complicating diagnosis.
    • Four illustrative cases of urethral duplication are presented.

    Findings:

    • A novel morphological classification system for urethral duplication is proposed.
    • The classification categorizes duplications based on orifice type (epispadiac, normotopic, hypospadiac, perineo-anal) and urinary transport.
    • It distinguishes between duplications with and without urinary transport, and further defines complete versus incomplete transport.

    Implications:

    • The proposed classification offers a clearer, more comprehensive approach to categorizing urethral duplications.
    • This system may improve diagnostic accuracy and facilitate treatment planning for these rare malformations.
    • Further research into the embryology of urethral duplication is warranted.
