Embryologic considerations of diphallus and associated anomalies
The Journal of Urology
|June 1, 1977
Summary
This study describes two cases of complete penile duplication (diphallus), one in an adult and one in an infant. Associated anomalies varied significantly by diphallus type, impacting posterior structures or bladder exstrophy.
Area of Science:
- Urology
- Pediatric Surgery
- Medical Genetics
Background:
- Diphallus, or complete penile duplication, is a rare congenital anomaly.
- Understanding associated anomalies is crucial for diagnosis and management.
Observation:
- Case 1: Adult with diphallus, bifid scrotum, hernias, rectal prolapse, vesicoureteral reflux, and staghorn calculi.
- Case 2: Infant with diphallus, bladder duplication, renal hypoplasia, spinal anomalies, imperforate anus, and pubic symphysis separation.
Findings:
- Shaft and glans diphallus showed a higher incidence of posterior structure anomalies (colon, bladder, spine).
- Glans-alone diphallus was more frequently associated with isolated bladder exstrophy.
Implications:
- The pattern of associated anomalies suggests distinct embryogenic pathways for different types of diphallus.
- These findings aid in predicting and managing complex congenital malformations.
