Male urethral diverticulum: the double density sign.

Area of Science:

• Urology
• Radiology
• Pediatric Surgery

Background:

• Voiding dysfunction in young males can stem from anatomical urethral defects.
• Urethral diverticula are often overlooked diagnostic challenges.
• Proper retrograde urethrography technique is crucial for diagnosis.

Observation:

• Two cases of young male patients with voiding dysfunction due to urethral diverticula are presented.
• The importance of dynamic retrograde urethrography technique is discussed.
• A novel radiologic sign associated with posterior bulbar urethral diverticulum is identified.

Findings:

• Dynamic retrograde urethrography is essential for identifying urethral diverticula.
• A specific radiologic sign aids in diagnosing posterior bulbar urethral diverticula.
• Accurate diagnosis prevents delayed treatment of voiding dysfunction.

Implications:

• Improved diagnostic accuracy for urethral diverticula in pediatric patients.
• Enhanced understanding of voiding dysfunction causes in young males.
• Potential for earlier intervention and better patient outcomes through advanced imaging techniques.
