Abstract

Purpose: The AMS 700CXM* inflatable penile prosthesis with medium controlled expansion cylinders was introduced in 1990 to provide a device with controlled expansion in girth and fitness for Asian men. We reviewed our experience with the AMS 700CXM prosthesis with particular regard to postoperative complications and reliability. Materials and Methods: From January 1991 to April 1999, 273 men with erectile dysfunction underwent primary penile prosthesis implantation with the AMS 700CXM. Functional status of the prosthesis was assessed retrospectively by reviewing the medical records and a telephone interview. Results: Patient age was 24 to 78 years and mean followup was 49 months. Of the 28 complications (10.3%) 8 (3%) were nonmechanical and 20 (7.3%) were mechanical. Nonmechanical complications included infection in 2 cases, erosion in 3, surgical complications in 2 and tube kinking in 1. Mechanical complications involved a cylinder tear in 11 cases (4%), pump failure in 4 (1.5%) and a reservoir tear in 2 (0.7%). Mechanical reliability of the device was 98.2% after 2, 95.7% after 3 and 90.4% after 5 years. Conclusions: The AMS 700CXM is suitable for Asian men and its mechanical reliability is excellent. However, more device modifications are needed to guarantee good reliability during long-term followup.
