Anatomy of the Rectourethral Fistula in ARM

Topic overview

This educational resource presents a standardized anatomic classification system for rectourethral fistulae in males with anorectal malformations, correlating distal colostogram findings with precise fistula levels. The classification guides surgical approach selection—posterior sagittal versus laparoscopic/open abdominal—improving preoperative counseling and outcomes stratification.

Key takeaways

High-pressure distal colostogram is essential for visualizing recto-urethral fistulae but precise urethral communication level can be difficult to interpret
Fistula anatomy determines surgical approach: posterior sagittal incision vs abdominal laparoscopy/laparotomy
Standardized anatomic correlation between colostogram findings and fistula level aids family counseling and outcomes stratification
Recto-urethral fistulae are the most common presentation in males with anorectal malformations
Accurate preoperative fistula localization helps predict rectal reachability and optimize surgical planning
