Penile cancer treatment with preservation of sexual function Penile cancer is a relatively rare malignant disease, which can cause great physical and psychological trauma to patients due to its special location. This provides us with the opportunity to cure the disease and also places higher demands on us to maximize the preservation of the patient’s organ function while curing the disease. For patients with superficial penile cancer, the safety and feasibility of choosing to perform surgery to preserve the head of the penis has been confirmed by some clinical studies. For patients with early-stage penile cancer who strongly request to preserve sexual function, our urology department has achieved good results by transferring the adjacent flap for glans repair and plastic surgery and radioactive particle implantation for penile cancer with glans preservation to treat the disease and preserve sexual function at the same time. Typical case 1] A patient with penile cancer in the ventral prepuce plate who strongly requested to preserve sexual function, this is the preoperative photo. In the second stage, we performed radioactive particle implantation + small incision bilateral inguinal lymph node dissection to preserve the sexual function as much as possible. Typical case 2] Glans mass, glans defect after mass excision, glans reconstruction by transferring scrotal flap, preserving better sexual function.
