Partial duplication of the male urethra

Area of Science:

• Urology
• Embryology
• Anatomy

Background:

• Urethral duplication is a rare congenital anomaly.
• Most cases present in childhood with urinary issues.
• This case highlights a unique presentation in adulthood.

Observation:

• A male patient presented with late-onset urinary incontinence.
• Imaging revealed a partial duplication of the urethra.
• The primary urethral channel was normal.
• An accessory urethral channel followed a markedly lateral course.

Findings:

• The case represents a partial urethral duplication with atypical anatomical features.
• The late presentation with incontinence, normal primary urethra, and lateral accessory urethra are distinguishing characteristics.
• An integrated anatomic and embryological classification for urethral duplication is proposed.

Implications:

• This case expands the understanding of urethral duplication variations.
• The proposed classification may aid in diagnosing and managing similar rare conditions.
• Further research into urethral development anomalies is warranted.
