    Summary
    This summary is machine-generated.

    Primary obstructed megaureters require careful differentiation from other causes. Surgical intervention is reserved for specific complications to ensure optimal patient outcomes.

    Area of Science:

    • Urology
    • Nephrology

    Background:

    • Megaureter terminology, histology, and etiology are inconsistently reported.
    • Distinguishing primary obstructed megaureters from those due to infravesical obstruction is crucial due to differing characteristics and treatments.

    Purpose of the Study:

    • To analyze the clinical presentation, management, and outcomes of primary obstructed megaureters in adult patients.
    • To establish criteria for surgical intervention versus conservative management.

    Main Methods:

    • Retrospective study of 43 adult patients with 54 primary obstructed megaureters.
    • Exclusion criteria included infravesical obstruction, reflux, and neurogenic disorders.
    • Evaluation of symptoms, renal function, ureteral transport capacity, and histological findings.

    Main Results:

    • Common symptoms included flank pain, infection, and hematuria.
    • 25 patients underwent surgery, while 29 were managed conservatively.
    • Criteria for surgery were based on symptom severity, renal function, and ureteral pathology.

    Conclusions:

    • Primary obstructed megaureters necessitate a clear diagnostic approach.
    • Conservative management is preferred unless specific complications arise.
    • Surgical treatment should be reserved for severe complications like renal function decline or recurrent infections to maintain the procedure's integrity.
