Summary
Restoring continence in exstrophy-epispadias complex repair is achievable. Reassembling the periurethral striated muscular complex via sagittal splitting of perineal tissue improves pelvic anatomy and vesicourethral function.
Area of Science:
- Urology
- Pediatric Surgery
- Reconstructive Surgery
Background:
- Continence is a significant challenge in exstrophy-epispadias complex (EEC) repair.
- The anatomical components of EEC are displaced but present, offering potential for reconstruction.
- Existing techniques aim to restore normal genital anatomy and bladder neck positioning.
Purpose of the Study:
- To describe a penile disassembly technique extension for EEC repair.
- To highlight the identification and reassembly of the perineal striated muscular complex.
- To improve bladder neck positioning within the pelvic diaphragm for continence.
Main Methods:
- Surgical repair of bladder exstrophy and epispadias in 13 consecutive patients (10 male, 3 female).
- Utilized sagittal incision and bipolar electrical stimulation to identify and reapproximate pelvic muscle components.
- Periurethral muscle complex reassembly along the posterior urethra was a key step.
Main Results:
- Good cosmetic outcomes in 12 patients; 1 required secondary urethroplasty.
- Mild pyelectasis in 3 cases; no renal function deterioration.
- Continence with cyclic voiding achieved in 54% of patients; daytime control in 23%.
Conclusions:
- Early restoration of physiological vesicourethral balance is feasible for continence in EEC.
- Sagittal splitting and midline reassembly of the periurethral striated muscular complex reconfigure pelvic anatomy.
- This approach facilitates better restoration of coordinated vesicourethral activity for improved continence.
