めぐみ Penile Implants For Erectile Dysfunction
Penile implants are a treatment for erectile dysfunction. They consist of two artificial cylinders surgically put in your penis. When you press on a pump in your scrotum, fluid (usually saline) moves to the cylinders and they expand, making an erection.
You can move the cylinders into other positions for sexual activity or to hide them. You can also press a valve to deflate the cylinders and return them to their flaccid state.
What is a penile implant?
Erectile dysfunction (ED) is common for men, but it doesn’t have to be. Most urologists consider penile implants the only true cure for ED that works without requiring taking pills. A man with a penile implant can achieve and maintain a firm erection for sex whenever he wants, for as long as he wants. The procedure is relatively fast and simple, with little recovery time.
To determine if you’re a good candidate for penile implants, your health care provider will review your medical history and do a physical exam. He will ask questions about your ED and what medications you’re taking, as well as check your blood pressure and examine your groin and scrotum for signs of infection or other problems with your penis.
The most popular type of penile implant is an inflatable prosthesis. It consists of two cylinders that are filled with fluid from a reservoir under the lower abdomen and connected to a pump in the scrotum between your testicles. The cylinders are inflated when you’re ready for sex, and they can be manipulated to create different types of erections.
Penile implants are highly reliable, but in some cases the implants may break or malfunction. The most common problem is that the device becomes stuck inside the penis or loses its ability to inflate, but more rare issues can occur, including internal erosion and adhesion.
Inflatable penile prosthesis (IPP)
Surgical implantation of an inflatable penile prosthesis (IPP) remains the gold standard treatment for severe erectile dysfunction that is unresponsive to conservative and noninvasive therapies. IPP implantation is associated with high patient and partner satisfaction rates, yet it is not without complications.
The most common types of IPPs are the Boston Scientific AMS 700 and Coloplast Titan, which both have two inflatable cylinders that sit artificial penis inside your penis, a pump in the scrotum, and a fluid reservoir under your abdomen. The cylinders are filled with a salt water-based solution through tubes that connect to the pump. When you want an erection, the pump is pressed to inflate them, similar to a natural penis. To deflate the cylinders, you press a deflation valve at the base of the pump, which drains the fluid back into the reservoir.
During IPP implantation, several anatomic structures are at risk of injury, including the urethra, rectum, scrotal skin, corporal tissue and abdominal structures. Thorough knowledge of the relevant anatomy is essential for avoiding inadvertent damage. In particular, the penis itself is vulnerable to intraoperative injuries, such as urethral injury, corporal perforation and implant crossover. This can result in discomfort, pain and reduced quality of life. To reduce these risks, it is important to select suitable patients and to follow safe surgical principles.
Semi-rigid penile prosthesis (SRP)
A semi-rigid implant is a pliable rod that remains rigid at all times and is concealed inside the body. To use it, you manually bend it up for an erection and down for concealment. A number of malleable implants have been developed and used worldwide, including the AMS 600 Spectra (Minneapolis, MN, USA) and Coloplast Genesis (Minneapolis, MN, US). Other examples include the ESKA Jonas prosthesis (Germany), Virilis implants (Italy), the Silimed penile prosthesis (Brazil) and the Argentinean Promedon tube prosthesis (Cesar Ortiz Promedon).
These devices are simple to use, completely concealed and produce an erection that looks and feels more like a natural one. They also don’t change your sensitivity, sex drive or ability to ejaculate.
During sexual intercourse, you press a release bar located at the upper aspect of the control pump that transfers saline from an abdominal reservoir into the cylinders of the prosthesis. This causes the cylinders to fill with fluid which produces a rigid erection of increased girth and length. The erection will remain until the release bar is again activated, draining the fluid back into the abdominal reservoir and returning the penis to its flaccid state. This can be repeated as needed. Some models have a limited amount of expansion in both length and girth while others have only length augmentation.
Other types of penile implants
Penile implants may also help restore a more natural appearance to the penis in men with disfiguring conditions like Peyronie’s disease. The device can also help correct changes in the shape of the penis caused by traumatic injury, previous surgery or medical conditions such as diabetes.
This type of implant consists of an inflatable pair of silicone cylinders that sit in Dildo Manufacturers the glans and a pump that sits in the scrotum or abdomen. When you want an erection, you use the pump to send fluid into the cylinders to inflate them. When you’re ready to deflate, you simply press a release valve to return the cylinders to a soft, flaccid state.
The surgery for a penile implant is relatively quick and usually an outpatient procedure. The cylinders (or the bendable rods in a malleable implant) are surgically placed into your genital area through a small incision, and the pump or reservoir is placed in the scrotum.
As with all medical procedures, there’s a risk of complications from a penile implant. However, the infection rate after this surgery is incredibly low — less than 1% of the time. Other potential problems include internal erosion, which could cause the silicone rods in your penis to wear down and shift their position within your body. In rare cases, an implant could malfunction, requiring surgery to repair or replace it.
