Retrograde urethrography may show a false stricture in the bulbous urethra. This artifact, not seen on urethroscopy, has a clear anatomical explanation.

Area of Science:

  • Urology
  • Diagnostic Imaging
  • Medical Illustration

Background:

  • Retrograde urethrography is a key diagnostic tool for urethral strictures.
  • Accurate interpretation is crucial for effective patient management.
  • Potential imaging artifacts can complicate diagnosis.

Observation:

  • An apparent proximal bulbous urethral stricture was observed on retrograde urethrography.
  • This finding was not corroborated during subsequent urethroscopy.
  • Two cases illustrating this diagnostic discrepancy are presented.

Findings:

  • The study identifies a specific imaging artifact in retrograde urethrography.
  • Anatomical review explains the false positive finding of a proximal bulbous urethral stricture.

  • Urethroscopy serves as the definitive diagnostic method.

    • Implications:

    • Clinicians should be aware of this potential urethrography artifact.
    • Avoidance of unnecessary interventions based on false positive findings.
    • Improved diagnostic accuracy in evaluating urethral strictures.
