Infection‐induced urethral defect treated by urethral reconstruction with a radial forearm flap

A 47‐year‐old man was admitted with the chief complaint of a urethral defect. An approximately 17‐cm defect of the urethra seemed to have been occurred by the infection of implanted foreign bodies in the penile skin. Reconstruction of the urethra and the ventral skin was performed with a free radial forearm flap. A fistula formed at the proximal anastomosis after the operation, but was controlled conservatively. Urethral stricture at the proximal anastomosis subsequently developed. A urethral stent made of shape memory alloy was placed with the preservation of voiding function.
