VACUUM CONSTRICTION DEVICE AND PENILE PROSTHESIS IN THE TREATMENT OF ERECTILE DYSFUNCTION
MARCH 27, 2019 @1.15 PM
Penile prostheses are highly effective in the treatment of erectile dysfunction. Serendipitously, using an external vacuum device to augment prosthetic erection provides a dramatic objective improvement in erection and increases overall satisfaction with intercourse.
Pantai Hospital Kuala Lumpur visiting consultant urologist Dr Poongkodi Nagappan explained that there are three types of devices that are used to promote prosthetic erection:
Vacuum constriction devices
Vascular reconstructive surgery
Vacuum constriction devices
Vacuum constriction devices non-invasive consists of a vacuum chamber, pump and a constriction ring.
She explained that this method is done by first lubricating, loading the ring onto cylinder base, placing the cylinder over penis and pressing base firmly against the pubis, slowly activating the pump, pulling the constriction band onto base of penis and finally removing the cylinder.
This takes two to three minutes to achieve an erection while the constriction band in placed for 30 minutes.
“Results are close to normal with sufficient rigidity and has been proven with patient and partner satisfaction rates, especially older men in long-term relationships.”
However, the vacuum constriction devices are cumbersome. It can also cause purple, cold and numb bruising.
This method, she said is inappropriate in mild ED and ineffective in severe ED, vascular insufficiency and fibrosis.
Penile Prosthesis Implantation
There is two methods; the malleable implant and the inflatable implant.
The malleable implant consists of two semi-rigid, bendable rods that can be manipulated to create an erection. It is easier to use, provides constant penile rigidity with a lower risk of mechanical failure. It is also generally less expensive.
The Inflatable implant, on the other hand, consists of a pair of cylinders, pump and a reservoir.
“When a man desires sexual activity, all he has to do is squeeze the pump that is located in his scrotum firmly a few times until an erection is achieved. By squeezing the pump, fluid is transferred from the reservoir into the cylinders. A man’s erection after implant surgery looks and feels so natural that there have been cases where a partner has not even been aware that an implant was present,” she said.
It also has a reliability rate of 97.5 per cent at five years with a lifetime replacement policy.
