“…Thus, infection rates of more than 20% has been reported with older implants [8]. Likewise, early rates of mechanical failure with the three-piece inflatable implants were high [8,9]. Possible problems include autoinflation, fluid leakage, tubing fracture, aneurysmal dilatation of the cylinders and connector disruption.…”

Introduction Long-term revision-free survival, greater than 10 years has never been reported for inflatable penile prostheses. We conducted a historical prospective study to estimate 10 and 15 years survival of first time (virgin) implantations in 2,384 patients with four different models. Aim Evaluation of 10- and 15-year mechanical and overall revision-free survival of inflatable penile prostheses. Main Outcome Measures Kaplan–Meier product limit method, and comparison using the log rank test, were used to estimate the 10- and 15-year revision-free survival. Methods Data were obtained from medical records and patient interviews, entered into a computerized database, and analyzed by a third party. Information included implant type, date, revision history with date, and reason. Fourteen different inflatables were examined. Mentor Alpha 1, Mentor Alpha NB, AMS 700 CX, and AMS 700 Ultrex had usage for an extended period of time. Because of failure times being confounded as a result of prior implants, only virgin implants were examined. Results For the entire series, estimated 10-year revision-free survival for all reasons was 68.5% and the 15-year revision-free survival was 59.7%. Freedom from mechanical breakage at 10 years was 79.4%; 15 years was 71.2%. Recent mechanically enhanced models did even better. In 1992, Mentor Alpha added pump reinforcement to forestall mechanical breakage. This improved 10-year survival from 65.3% to 88.6% (P = 0.0001). In January 2001, AMS CX added a parylene coating to the cylinders that increased 3-year mechanical survival from 88.4 to 97.9% (P = 0.0002). Conclusions This is the first report on long-term reliability of inflatable penile prostheses. We estimated 60% of these virgin implants would survive 15 or more years without revision or extraction. Newer enhanced models are currently available, and our tracking predicts even better long-term survival for these devices.

“…The implantation of a penile prosthesis has in the past been associated with technical difficulties and a high complication rate such as infection, persistent pain, cavernous perforation, mechanical dysfunction, malposition, erosion into the bladder and bowel and gangrene. While improved technology, materials and surgical techniques have reduced the number of revisions for mechanical failures, device related complications including infection and mechanical failure developed in 20.7–32.0% of cases 3–6 …”

“…While improved technology, materials and surgical techniques have reduced the number of revisions for mechanical failures, device related complications including infection and mechanical failure developed in 20.7-32.0% of cases. [3][4][5][6] Urethral stricture after implantation of a three-piece inflatable penile prosthesis has not been reported until now. However, urethral stricture occurring as a result of compression of twisted tubing in three-piece inflatable penile prosthesis (Mentor Corporation) implants induces a complicated situation in which multiple staged operations are required.…”

Objective: The aim of this study was to find the mechanism that causes urethral stricture with a view to preventing its occurrence after implantation of a three-piece inflatable penile prosthesis. Methods: When implanting a three-piece inflatable penile prosthesis, we draw two longitudinal lines parallel to the long axis of the proximal cylinder and the tubing leading from each cylinder into the cavernosal space, to prevent 360 degree rotation of the cylinder. Results: From September 1993 to February 2007, a total 86 three-piece penile prosthesis implantations were carried out in 70 patients. Urethral stricture occurred in 5.8% (5/86) of the prosthesis operations. Fifteen three-piece penile prosthesis reinsertions were carried out in 17.4% (15/86) of the prosthesis recipients. Conclusions: A successful outcome was achieved in the patients who received penile implantation with the three-piece penile prosthesis that were marked with longitudinal lines. The rotation of the cylinder may cause compression on the urethra from the tubing leading from the cylinder or pump crossing over the urethra and resulting in urethral stricture. The drawing of longitudinal lines at the proximal cylinder and tubing leading from the cylinder could prevent the urethral stricture induced by tubes that are twisted by rotation of the cylinder.

Clinical experience with the mentor alpha-1 inflatable penile prosthesis: Report on 65 patients

Abstract: The Mentor Alpha-1 IPP is an efficient treatment for ED in situations where less invasive therapy has failed. The risk of infection or mechanical failure must not be ignored. Patients should be informed of this risk before agreeing to implantation surgery.
