preputial island flap

Full Definition

A preputial island flap is a vascularized flap of preputial (foreskin) tissue based on the dartos fascial blood supply, commonly used for urethral reconstruction in hypospadias repair. The flap maintains its blood supply through the dartos pedicle, allowing it to be rotated ventrally to bridge urethral gaps or provide coverage. This technique is particularly useful for proximal hypospadias where local tissue is insufficient for primary repair.

Usage

Usage note: Emphasize that this is a vascularized flap, not a free graft; requires adequate preputial tissue for harvest.
