Urachal remnants (UR) are frequently visualized using ultrasound, especially in younger individuals. These findings are often a normal variant and not indicative of pathology unless enlarged or symptomatic.

Area of Science:

  • Radiology
  • Medical Imaging
  • Pediatric Imaging

Background:

  • The urachus is a remnant of the allantois, typically obliterated after birth.
  • Persistence of urachal remnants can lead to various clinical conditions.

Purpose of the Study:

  • To determine the frequency of visualizing urachal remnants (UR) via ultrasound.
  • To characterize the sonographic patterns of urachal remnants.

Main Methods:

  • Ultrasound examinations were performed on 250 patients (age range: 1 month to 91 years).
  • Patients were categorized into four age groups for analysis.
  • Diagnostic criteria included a midline mass between the rectus abdominus muscle and anterior bladder wall.

Main Results:

  • Urachal remnants were identified in 36% of patients, with higher prevalence in younger age groups (<35 years).
  • Common sonographic patterns included nodular (87%) and tubular (13%) structures.
  • Echogenicity was variable, and dimensions averaged 13.5 x 12.6 x 5.2 mm.

Conclusions:

  • Ultrasound commonly visualizes urachal remnants, particularly in pediatric and young adult populations.
  • Urachal remnants are generally considered a normal variant.
  • Enlargement or associated clinical signs warrant further investigation for potential pathology.
