Types of Penile Implants
There are two main types of penile implants:
- Inflatable implants. Inflatable devices, the most common type of penile implant used, can be inflated to create an erection and deflated at other times. Three-piece inflatable implants use a fluid-filled reservoir implanted under the abdominal wall, a pump and a release valve placed inside the scrotum, and two inflatable cylinders inside the penis.To achieve an erection, you pump the fluid from the reservoir into the cylinders. Afterward, you release the valve inside the scrotum to drain the fluid back into the reservoir. The two-piece model works in a similar way, but the fluid reservoir is part of the pump implanted in the scrotum.
- Semirigid rods. Semirigid devices are always firm. The penis can be bent away from the body for sexual activity and toward the body for concealment.A positionable penile implant is a semirigid device with a central series of segments held together with a spring on each end. It can maintain upward and downward positions better than other semirigid rods can.
Other special designs can fit a shortened penis, or one that’s larger than average. Some inflatable penile implants are also available with antibiotic coatings, which might help reduce the risk of infection.
To assess the satisfaction profiles following penile prosthesis surgery in patients with erectile dysfunction (ED) in their seventh decade of life.
PATIENTS AND METHODS:
In all, 174 patients received, for the first time, a penile prosthesis between 1990 and 2007 in our department. Among these, 35 patients were aged > or =70 years at prosthesis implantation. Of these, 18 patients were still alive at the time of follow-up. Using a telephone survey, patients were asked to answer the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) as well as the International Index of Erectile Dysfunction (IIEF). Another question in the survey was developed by the authors based on a comprehensive review of the literature, which assessed the usefulness of the device for the patient and the degree of their usage. This was formulated as follows: How many times per 2 weeks do you have a sexual intercourse?
In all, 15 of 18 patients were either very or somewhat satisfied (83%). At follow-up 11 out of 15 (73%) patients were using their prosthesis regularly. The mean IIEF and EDITS scores were 21.80 and 75.20, respectively.
A penile prosthesis remains a highly promising treatment in older patients with a similar satisfaction rate to those published for younger patients. Thus, the motivation of the patient and not the age of the patient should be the main determinant factor in this surgical procedure.
