    A rare case of primary obstructive megaureter presented as an asymptomatic pyeloureteral cast. This condition affected a non-functioning kidney, highlighting an unusual clinical manifestation.

    Area of Science:

    • Urology
    • Nephrology
    • Pediatric Surgery

    Background:

    • Primary obstructive megaureter (POM) is a congenital condition characterized by ureteral dilation without distal obstruction.
    • It typically presents in infancy or childhood with symptoms like urinary tract infections or abdominal masses.
    • Asymptomatic presentations are less common, particularly in adults.

    Observation:

    • A rare case of POM was identified incidentally.
    • The presentation involved a pyeloureteral cast within a non-functioning kidney.
    • This asymptomatic finding in an adult patient is highly unusual.

    Findings:

    • The pyeloureteral cast was the sole indicator of POM.
    • The affected kidney showed no functional capacity, likely due to chronic obstruction.

  • Histopathological examination confirmed the nature of the cast and ureteral changes.

    • Implications:

    • This case expands the spectrum of clinical presentations for primary obstructive megaureter.
    • It underscores the importance of considering rare etiologies in cases of non-functioning kidneys.
    • Diagnostic and management strategies for POM may need to account for such atypical, asymptomatic presentations.
