[Plastic surgical correction of megaureter].

    Summary

    Surgical management of megaureters in children and adults, particularly ureterocystoneostomy (UCN), has evolved. Conservative treatment is often sufficient for primary obstructive megaureters, while secondary megaureters benefit from addressing infravesical obstruction.

    Area of Science:

    • Urology
    • Pediatric Surgery
    • Nephrology

    Context:

    • Megaureters, characterized by ureteral dilation, affect both pediatric and adult populations.
    • Surgical interventions have been historically employed for megaureter treatment.
    • Treatment strategies have evolved over a nearly two-decade period.

    Purpose:

    • To analyze surgical outcomes for megaureters treated between 1967 and 1986.
    • To evaluate the efficacy of different surgical techniques, including ureterocystoneostomy (UCN) and ureteral tapering.
    • To assess changes in treatment paradigms for primary and secondary megaureters.

    Summary:

    • A retrospective review of 185 children and 21 adults with megaureters treated surgically.
    • Ureterocystoneostomy (UCN) was the primary surgical approach, with the Psoas Hitch technique showing improved results after 1977.
    • Conservative management and addressing infravesical obstruction were increasingly favored, especially for secondary megaureters, reducing the need for ureteral tapering and reimplantation.

    Impact:

    • Demonstrates a shift towards less invasive management for megaureters, reserving ureteral tapering for select cases.
    • Highlights the effectiveness of UCN, particularly the Psoas Hitch technique, in managing obstructive megaureters.
    • Provides evidence for conservative approaches in primary obstructive megaureters and emphasizes relieving infravesical obstruction in secondary megaureters.
