Megaureter is not a single condition but has various causes. Diagnosis uses imaging, and non-operative management is preferred, with surgery reserved for severe cases.

Area of Science:

  • Pediatric Urology
  • Medical Imaging

Background:

  • Megaureter classification involves refluxing, obstructive, and non-refluxing/non-obstructive types.
  • Primary and secondary megaureter are further subdivisions.
  • Antenatal ultrasound increasingly identifies cases before symptoms arise.

Purpose of the Study:

  • To review the classification, diagnosis, and management of megaureter.
  • To highlight the impact of prenatal imaging on megaureter diagnosis and treatment.

Main Methods:

  • Review of diagnostic modalities including ultrasound, voiding cystourethrography, urography, diuretic renography, and Whitaker test.
  • Discussion of clinical presentation and classification systems.

Main Results:

  • Prenatal and neonatal echography have significantly altered the natural history of megaureter.
  • Non-operative management is now the preferred approach.

    • Conclusions:

    • Megaureter management has shifted towards conservative strategies.
    • Surgical intervention is reserved for cases with significant obstruction, declining renal function, or recurrent UTIs despite prophylaxis.
