    Summary
    This summary is machine-generated.

    Primary obstructive megaureter requires a full urologic evaluation to rule out other causes. Surgical intervention, including excision and reimplantation, yields the best outcomes for this condition.

    Area of Science:

    • Pediatric Urology
    • Urologic Surgery

    Background:

    • Primary obstructive megaureter is a congenital condition characterized by ureteral dilatation.
    • Characteristic clinicoradiologic features are present, but a comprehensive workup is essential to exclude other causes of ureteral dilatation.

    Purpose of the Study:

    • To retrospectively evaluate clinicoradiologic features and treatment outcomes in primary obstructive megaureter.
    • To determine optimal management strategies based on renal and ureteral function.

    Main Methods:

    • Retrospective review of 65 cases of primary obstructive megaureter.
    • Evaluation of clinicoradiologic findings and treatment approaches.
    • Assessment of surgical outcomes including excision, caliber reduction, and reimplantation.

    Main Results:

    • Surgical excision of the obstructive segment, with caliber reduction when necessary and reimplantation, demonstrated the best results.
    • Nephrostomy drainage before ureteral remodeling was beneficial in selected cases.
    • Conservative management is viable for children with mild symptoms and slight ureteral dilatation.

    Conclusions:

    • Complete urologic workup is crucial for accurate diagnosis of primary obstructive megaureter.
    • Treatment planning should be individualized based on renal and ureteral function.
    • Surgical repair offers the most effective treatment, while conservative options exist for select pediatric cases.
