[The interest of early rehabilitation with intracavernous injections following complete prostatectomy].

Several factors influence erectile function following radical prostatectomy: cancer and its extension, the technique of nerve sparing, the patient and his relationship with his partner, and the rapidity and mode of post-surgical management. Depending on the surgical technique, this can result in permanent and total erectile dysfunction with severe fibrotic modifications in the absence of nerve sparing, or erectile dysfunction that can be restored by the early management when the nerves have been spared. Treatment within the month following surgery with intracavernous injections of PFE1 improves oxygenation of the cavernous corpus, thus limiting the development of tissue fibrosis, and hence increasing the penile blood flow. In clinical practice, emphasis should be made on the psychological importance of the early return of erections and sexual activity.
