Summary

The aim of this study is to evaluate the outcomes, feasibility, and complication profile of re-operative hypospadias repair using tubularized incised plate urethroplasty as a single-stage procedure in a single-center experience.

Detailed description

Hypospadias repair remains one of the most common reconstructive procedures in pediatric urology; however, re-operative hypospadias represents a challenging subset due to distorted anatomy, urethral plate scarring, deficient local tissues, and higher complication rates compared with primary repairs. The tubularized incised plate (TIP) urethroplasty, originally described by Snodgrass, revolutionized primary hypospadias repair and has since been adapted for selected reoperative cases. Contemporary evidence suggests that despite prior surgery and scary, a well-vascularized urethral plate of adequate width can still be successfully tubularized following a midline relaxing incision, offering acceptable functional and cosmetic outcomes.

Conditions

• Re-operative
• Hypospadias
• Tubularized Incised Plate
• Urethroplasty

Interventions

Type	Name	Description
PROCEDURE	Tubularized Incised Plate Urethroplasty	All procedures were performed under general anesthesia using the tubularized incised plate technique. After completing penile degloving and exposure of the urethral plate, a midline longitudinal incision was made along the entire length of the plate to allow tension-free tubularization. The urethral plate was then tubularized over an appropriate-sized urethral catheter using fine absorbable sutures. A well-vascularized dartos flap was harvested and interposed as a protective layer over the neourethra, followed by meticulous skin closure.
