case_images: A 50-year old healthy man presented with a brown irregular flat lesion surrounding the tip of the glans, involving the urethral meatus (Figure 1).

case_images: The distal urethra was excised with a 1.5 cm safety margin, confirmed as healthy by a preliminary histological examination (Figure 2A). A dorsal transverse preputial flap was created, and a template-tailored free graft was harvested from the internal leaflet of the foreskin (Figure 2B). The skin graft was prepared separately by accurate defatting until achieving a thin thickness, meshed with scalpel, laid circularly for 180 degrees on the tip of the corpora cavernosa, and sutured with 4-zero polyglactin interrupted stitches (Figure 2C).

case_images: The second-stage surgery was planned after 6 months at consolidated first-time reconstruction (Figure 3A). The plate of preputial graft was incised along its edges and tubularized using a running 5-zero polyglycolic suture upon a 14 Fr catheter (Figure 3B). A dartos tail was used to cover the neourethra to protect the suture, and then the shaft was covered with a tension-free penile skin flap (Figure 3C).

case_images: At 24 months after the second-stage surgery, the urethra was shown to be negotiable by a 16 Fr catheter (Figure 4).
