Summary

Sonography offers a new, comfortable method for examining the anterior urethra, proving as effective as traditional X-rays for diagnosing urethral stricture disease and related conditions.

Area of Science:

  • Urology
  • Medical Imaging
  • Diagnostic Techniques

Background:

  • Anterior urethral stricture disease diagnosis traditionally relies on invasive methods.
  • Limitations exist in current imaging techniques for evaluating urethral pathology.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of a novel sonographic technique for anterior urethra examination.
  • To compare sonographic urethrograms with roentgenographic and cystoscopic findings.

Main Methods:

  • A sonographic technique was developed and applied to 22 men with suspected stricture disease.
  • Patients underwent sonographic urethrograms, roentgenographic urethrograms, and 17 had cystoscopic examinations.

Main Results:

Related Experiment Videos

  • Sonographic urethrograms demonstrated diagnostic accuracy comparable to roentgenographic findings in 19 out of 22 patients.
  • The technique successfully identified a bulbar urethral stricture missed by retrograde urethrogram in one patient.
  • Extraluminal structures like the urethral wall, corpus spongiosum, and bulb were clearly visualized.

    • Conclusions:

    • Sonographic urethrograms provide valuable insights into both luminal and extraluminal anterior urethral anatomy.
    • This non-invasive method shows significant potential for diagnosing urethral stricture disease, foreign bodies, and straddle injuries.
    • Further long-term studies are recommended to fully establish its diagnostic capabilities.
