[A single-stage reconstruction in hypospadias using a vascularized preputial flap]
1Urologická klinika Fakultní nemocnice 2 s FP, Praha, CSc.
Summary
This study details a modern surgical technique for hypospadias repair in 31 boys, achieving excellent functional and aesthetic outcomes. The single-stage operation utilizes vascularized tissue for effective reconstruction of the external genitalia.
Area of Science:
- Urology
- Pediatric Surgery
- Plastic Surgery
Context:
- Hypospadias, a congenital condition, often requires complex surgical reconstruction.
- Chordee, a ventral curvature of the penis, frequently accompanies hypospadias.
- Microsurgical techniques and vascularized flaps offer advanced reconstructive options.
Purpose:
- To evaluate the efficacy and outcomes of a specific hypospadias reconstruction technique using a preputial flap.
- To assess the complication rates and functional results of this single-stage surgical approach.
- To determine the suitability of this method for penile and penoscrotal hypospadias with chordee.
Summary:
- The study reports on 31 boys (10 months to 15 years) who underwent hypospadias reconstruction using a vascularized preputial flap (Duckett's technique, with modifications in three cases).
- A double flap technique was predominantly used, covering the ventral penile side with the outer prepuce.
- Complications included urethral and meatal strictures, skin necrosis, and dehiscence, with 16.1% requiring open revision. Despite complications, excellent functional and aesthetic results were achieved in all patients.
Impact:
- This single-stage surgical procedure is indicated for penile and penoscrotal hypospadias with chordee.
- The use of vascularized tissue and microsurgical techniques allows for early, definitive reconstruction of external genitalia, ideally by one year of age.
- The findings support the use of this advanced technique for improved patient outcomes in hypospadias repair.
