P-05-010 Mechanical Failure with Inflatable Penile Prosthesis

In 1973, Scott et al. introduced the first inflatable penile prosthesis for the treatment of erectile dysfunction (ED). At that time, mechanical complications were more frequent, specially in the first years after implantation. Currently with technological evolution, is a less common condition, occurring typically more than 5 years after implantation, being the medically implanted device with the lowest replacement rate for mechanical failure. The most common mechanical complications are cylinder or reservoir leak, tubing fracture, cylinder aneurysm or conector disruption. The evidence of mechanical failure requires surgical revision of the prosthesis as well as replacement of all parts, once partial substituition is in association with a higher infection rate and frequent and repeated penile incisions tend to shorten the erections. We present a case of a 65 years old man who underwent implantation of a inflatable penile prosthesis 15 years ago for erectile dysfunction after radical prostatectomy. Patient presented incomplete insuflation of the prosthesis, with left angulation and penile shaft bulging. He underwent surgical revision with identification of a proximal aneurysm of the right cilynder. A total replacement of the prosthesis was performed.
