Diagnostic Approaches for Urethral Meatus Examination

Initial Assessment and Diagnostic Techniques

The European Association of Urology recommends carefully inspecting the external urethral meatus for visible abnormalities, including swelling, ecchymosis, discharge, blood, stenosis, or anatomical variations 1, 2
In males, drawing back the prepuce to avoid contamination when examining the meatus is advised 1
In females, cleaning the introitus using a sterile gauze swab before examination is necessary 1
The presence of blood at the meatus is a critical indicator of potential urethral injury, according to the World Journal of Emergency Surgery 3, 4
The American Urological Association suggests that urethroscopy is preferred over retrograde urethrography for penile injuries 3
For suspected urethral trauma, blood at the urethral meatus requires immediate retrograde urethrography, as recommended by The Journal of Urology 6, 3
Avoid blind catheterization before imaging in trauma cases, as this may worsen urethral injuries, warns the World Journal of Emergency Surgery 3
In patients with pelvic fractures and blood at the meatus, always evaluate for urethral injury before bladder catheterization, advises The Journal of Urology and the World Journal of Emergency Surgery 3, 4, 6

For suspected infection or STIs, collect urethral exudates for testing by inserting a cotton-wool or Dacron swab into the external urethral meatus, recommends Eurosurveillance 1
Apply collected material to microscope slides for immunofluorescence staining or place in transport media for viral culture or nucleic acid amplification tests, suggests Eurosurveillance 1
Establish prompt urinary drainage in patients with pelvic fracture-associated urethral injury, advises The Journal of Urology 6
For penile fracture with concomitant urethral injury, surgical exploration and repair is indicated, recommends The Journal of Urology 5
Avoid repeated attempts at placing a urethral catheter in trauma cases, as this may increase injury extent, warns The Journal of Urology 6

Never perform blind basketing (stone extraction without endoscopic visualization) as this risks urethral injury, warns The Journal of Urology 7
Avoid blind catheterization in suspected urethral trauma cases, advises The Journal of Urology and the World Journal of Emergency Surgery 6, 3
Do not rely solely on clinical diagnosis for genital lesions, as laboratory confirmation should always be sought, recommends Eurosurveillance 1
Avoid fluoroscopic imaging of stones alone without direct urethroscopic vision during procedures, warns The Journal of Urology 7
