Microsurgical Single Versus Double Dartos Flap in Distal Hypospadias Repair

Microsurgical Single Versus Double Dartos Flap in Distal Hypospadias Repair: A Prospective Randomized Trial

This study aims to compare the surgical and functional outcomes of microsurgical single dartos flap versus double dartos flap in distal hypospadias repair.

Hypospadias is recognized as a frequent congenital defect of the male urogenital system, with its prevalence exhibiting significant regional and ethnic disparities globally.

Despite continuous improvements in surgical methodology, the development of a urethrocutaneous fistula (UCF) remains a persistent and difficult postoperative challenge. Reported UCF rates fluctuate between 1% and over 20%, heavily influenced by factors such as the initial position of the meatus, the specific surgical approach, and the practitioner's level of expertise.

Expanding on the use of a single-layer dartos flap (SDF), recent research has focused on whether a double-layer dartos flap (DDF) provides enhanced protection against fistula formation.
