Summary
The double-faced onlay preputial flap (DOPF) offers improved blood supply for hypospadias repair. This technique preserves the urethral plate and provides well-vascularized coverage, with a complication rate comparable to other methods.
Area of Science:
- Urology
- Pediatric Surgery
- Reconstructive Surgery
Background:
- Hypospadias repair presents challenges in achieving adequate blood supply and coverage.
- Traditional techniques may lead to complications such as fistulas and necrosis.
Purpose of the Study:
- To evaluate the efficacy and safety of the double-faced onlay preputial flap (DOPF) for hypospadias repair.
- To assess the anatomical and vascular advantages of the DOPF technique.
Main Methods:
- Urethroplasty was performed on 15 patients with middle or posterior hypospadias using the DOPF technique.
- The inner flap face was used to create the neourethra, while the outer face provided ventral skin coverage.
Main Results:
- The DOPF technique demonstrated a reasonable blood supply and well-vascularized ventral skin coverage.
- A complication rate of 13% was observed, with one fistula and one case of dorsal skin necrosis.
- Neourethra viability could be assessed by observing the outer flap face.
Conclusions:
- The DOPF technique is a viable option for hypospadias repair, offering anatomical benefits and good vascularization.
- The complication rate associated with DOPF is similar to that of alternative surgical methods.
- This approach preserves the urethral plate and enhances ventral skin coverage.
