title: Reliability of AMS M700 inflatable penile prosthesis.
abstract: Two hundred ninety patients have been followed up for at least one year or longer after implantation of the AMS M700 inflatable penile prosthesis. One hundred twenty-seven males have been followed up for two years or longer. Eighty-six impotent men had a follow-up of eighteen months or longer. The remaining 77 patients were studied for at least twelve months or longer. There have been 3 mechanical failures of cylinders implanted secondary to nonabsorbable surgical sutures remaining from previous prosthetic surgery. There were no reservoir or pump malfunctions. Eight patients had a slow leak from the nonkinking tubing. Since a revision of the manufacturing process of the nonkinking tubing in September, 1983, there have been no further leaks. Life table analysis for survival in this group of patients showed a probability of survival at three years of 97.9 per cent. The satisfaction rate among patients is greater than 90 per cent.
