About

We aime to compare between Snodgrass and grafted Snodgrass repair in the outcome in distal penile hypospadias with urethral plate less than 8mm

Full description

The main goal for hypospadias repair is to achieve both cosmetic and functional normality.

Several surgical techniques for hypospadias repair have been developed that depend on the site of the urethral meatus in children The effect of the urethral plate characteristics on the surgical outcome of Snodgrass repair has been studied in many series. Some documented that urethral plate width has a significant impact on the complication rates Holland and Smith reported a high complication rate in Snodgrass repair with a urethral plate width of less than 8 mm 7 The augmentation of the urethral plate either with inlay graft (DIGU, Snodgraft, or G-TIP), Onlay preputial flap, or other flaps carries a better outcome than the original TIP in many studies Others denied any effect of the narrow urethral plate on the success rate We aim in this study to determine which is better in narrow urethral plate in distal penile hypospadias, as regarding surgical and cosmetic outcomes; Snodgrass or combined inner preputial graft with Snodgrass

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

50 participants in 2 patient groups

Snodgrass repair group

Active Comparator group

Description:

A relaxing incision is made in the midline by using scalpel or scissors from Within the meatus to the end of the plate. A 6 F stent is passed into the bladder. The neourethra is closed using a fine suture, 7-0 or 6-0 vicryl sutures in two-layer.

Treatment:

Procedure: Snodgrass repair

Snodgrass repair with graft group

Active Comparator group

Description:

A relaxing incision is made in the midline by using scalpel or scissors A free graft was measured and harvested from the inner prepuce and was defatted and sutured onto the incised urethral plate after the urethral plate was incised he graft was sutured overlying the incision line A 6 F stent is passed into the bladder. The neourethra is closed

Treatment:

Procedure: Snodgrass repair with graft
