Summary
The penile upward migration method offers a safe and effective surgical solution for penoscrotal transposition (PST), providing better cosmetic outcomes and reduced operative time compared to traditional techniques.
Area of Science:
- Pediatric Urology
- Congenital Malformations
- Surgical Techniques
Background:
- Penoscrotal transposition (PST) is a congenital anomaly often linked with hypospadias.
- Existing surgical methods for PST can lead to significant trauma, compromised blood supply, and poor cosmetic results.
Purpose of the Study:
- To evaluate the clinical efficacy and safety of the novel "penile upward migration method" for correcting penoscrotal transposition.
Main Methods:
- A retrospective case series of 35 patients undergoing the penile upward migration method between January 2018 and June 2023.
- The technique involves marking and excising a concentric circle around the penile base for upward migration.
- Applicable for isolated PST, residual PST post-hypospadias repair, or simultaneous correction of both conditions.
Main Results:
- 35 patients (29 partial PST, 6 complete PST) were analyzed, with a mean age of 51.6 months.
- Successful correction achieved in 33 cases, with minor complications (skin necrosis, hypertrophic scarring) resolving with treatment.
- High caregiver satisfaction reported regarding cosmetic outcomes using the modified Pediatric Penile Perception Score (PPPS).
Conclusions:
- The penile upward migration method is a safe, effective, and simpler alternative for PST correction.
- Offers advantages including shorter operative time, preserved penile blood supply, and improved aesthetic results with concealed scars.
- Further comparative studies are recommended to validate these findings.
