Urethral Plate Grafting for Deficient Urethral Plate in Exstrophy: An Alternative Method to Augment Urethral Plate

Area of Science:

• Pediatric Urology
• Reconstructive Surgery

Background:

• Short urethral plate is a significant challenge in managing bladder exstrophy and cloacal exstrophy.
• Current management strategies for exstrophy often face difficulties with inadequate urethral plate length.

Purpose of the Study:

• To evaluate the safety and efficacy of urethral plate grafting in pediatric patients with exstrophy and a deficient urethral plate.
• To assess the outcomes of pre-exstrophy closure urethral plate grafting.

Main Methods:

• Prospective study of six male patients with exstrophy and a urethral plate <10 mm.
• Urethral plate grafting using inner preputial or para-exstrophy skin grafts prior to exstrophy closure.
• Recorded parameters included age at grafting, graft type, age at closure, success of closure, and complications.

Main Results:

• All six patients (3 classic bladder exstrophy, 3 cloacal exstrophy) had successful urethral plate grafting without loss.
• Grafting resulted in a longer and wider urethral plate in all cases.
• Exstrophy closure was performed at a median of 3 months post-grafting with successful outcomes.

Conclusions:

• Pre-closure urethral plate grafting is a safe and effective surgical option for exstrophy patients with short or inadequate urethral plates.
• This technique provides a viable solution to improve urethral length and facilitate successful exstrophy closure.
