Summary
Isolated penile torsion affects 20% of newborns, with significant rotations over 45° in 4.3%. Surgical correction, often degloving and reattachment, is effective for severe cases, with dorsal dartos flap for persistent torsion.
Area of Science:
- Pediatric Urology
- Surgical Innovation
- Congenital Anomalies
Background:
- Isolated penile torsion is a congenital anomaly affecting newborn males.
- Understanding its incidence and optimal management is crucial for pediatric urologists.
Purpose of the Study:
- To report the incidence of isolated penile torsion in healthy children.
- To describe the surgical approach and outcomes for penile torsion.
Main Methods:
- Retrospective analysis of newborn babies with penile torsion between 2011 and 2014.
- Classification based on torsion angle and surgical intervention (degloving/reattachment or dorsal dartos flap) for rotations >45°.
Main Results:
- 20% incidence of isolated penile torsion (200/1000 newborns).
- 4.3% (43/1000) had torsions >45°, with 4 >90°.
- Surgical correction in 19 patients (mean age 12 months) showed high success rates, with 2 children having residual rotation <15°.
Conclusions:
- Isolated penile torsion occurs in 20% of newborns, with significant degrees (>45°) in 4.3%.
- Penile degloving with reattachment is sufficient for most cases; dorsal dartos flap is effective for persistent torsion.
- Prior circumcision does not impact surgical outcomes for penile torsion.
