Three Piece Penile Implant : Penile Erection almost simulating natural erection

A 35 year old man came to us with psychogenic impotence.He had tried PDE-5 inhibitors,sex therapy and psychiatric medications for a long time.
He was also tried Vacuum Erction device and intracavernosal injections but did not benefit.
Finally was given option of penile implant .He chose a three piece Mentor Coloplast Implant.The surgery was done and the device was kept in semideflated position .He was instructed to come after 6 weeks for operation of the device.
Surgery usually has one of three goals:
to implant a device that can cause the penis to become erect (Penile Implant surgery)
to reconstruct arteries to increase flow of blood to the penis (Penile revascularization surgery for patient with focal arterial stenosis-post-trauma)
to block off veins that allow blood to leak from the penile tissues (penile venous leak-particularly detected on Doppler showing persistence end-diastolic velocity more than 5 cm/sec)
Implanted devices, known as prostheses, can restore erection in many men with ED. Possible problems with implants include mechanical breakdown and infection, although mechanical problems have diminished in recent years because of introduction of Viagra but there are a group of patients who fail with medications and refuse or fail with Vacuum Erection Device. Inflatable implants consist of paired cylinders, which are surgically inserted inside the penis and can be expanded using pressurized fluid Tubes connect the cylinders to a fluid reservoir and a pump, which are also surgically implanted. The patient inflates the cylinders by pressing on the small pump, located under the skin in the scrotum. Inflatable implants can expand the length and width of the penis. They also leave the penis in a more natural state when not inflated.
Advantages with the penile impants are:
o Good rigidity
o Freedom from medications
o Outpatient/24HR surgery
o Resume sexual activity 4-6 weeks
o No loss of ability to ejaculate or achieve orgasm
Surgery to repair arteries can reduce ED caused by obstructions that block the flow of blood. The best candidates for such surgery are young men with discrete blockage of an artery because of an injury to perineum or fracture of the pelvis.Surgery to veins that allow blood to leave the penis usually involves an opposite procedure-intentional blockage. Blocking off veins (ligation) can reduce the leakage of blood
