OBJECTIVE Penile agenesis is a rare congenital abnormality with an incidence of 1 in 30 million births. We want to demonstrate in this video a new technique of neophalloplasty based on two transverse skin flaps from lower abdominal wall. METHODS The patient was placed into a prone position; the urethral meatus was found inside the rectum, 2 cm from the(More)

In this video, we demonstrate implantation of a penile prosthesis in a neophallus performed 10 years previously in a patient aged 21. METHODS Through a midline perineal incision aiming to reach the inferior surface of the pubic arch, we created a 16-cm tunnel(More)
