Summary
This study classifies male urethral duplications, detailing common epispadiac and rarer hypospadiac and spindle forms. It highlights the often-unrecognized bifid urethra with a pre-anal accessory track.
Area of Science:
- Urology
- Medical Genetics
- Embryology
Background:
- Urethral duplication is a rare congenital anomaly.
- Understanding its classification is crucial for diagnosis and treatment.
Observation:
- A classification system for male urethral duplications is presented.
- Clinical experience with various forms is detailed.
Findings:
- The epispadiac form is the most common, with complete, incomplete, or abortive variations.
- Hypospadiac forms are less common; spindle urethras are very rare.
- The bifid urethra with a pre-anal accessory track is relatively common but frequently misdiagnosed.
Implications:
- Accurate classification aids in understanding the spectrum of urethral duplication.
- Improved recognition of the bifid urethra may lead to earlier diagnosis and intervention.
- This classification can guide surgical planning and improve patient outcomes.
