Abstract
INTRODUCTION: AMS 700CX/CXM inflatable penile prosthesis is increasingly applied for the treatment of erectile dysfunction (ED). However, there are a few long-term survival data of the inflatable penile prosthesis (IPP) over 10 years. AIM: To determine the long-term mechanical reliability of AMS 700CX/CXM inflatable penile prosthesis in patients with ED. METHODS: A total of 438 consecutive patients with ED received implantation of an AMS 700CX/CXM penile prosthesis at our institution from January 1991 to April 2009. In 397 patients (90.7%), the medical records were available and current status of penile prosthesis could be obtained by a direct telephone interview. The overall and mechanical survival rates of penile prosthesis were evaluated using Kaplan-Meier method. MAIN OUTCOME MEASURES: Assessing the mechanical and overall survival rates of the AMS 700CX/CXM penile prosthesis using Kaplan-Meier analysis, and looking for clinical factors related to survival of the CX/CXM using log-rank test. RESULTS: Mean age of 397 patients was 63.1 years (range, 24-93) and follow-up duration was 113 months (range 1-219). Eighty-two patients (20.6%) experienced mechanical failure at a median follow-up of 82 months. Mechanical survival rate of the penile prosthesis was 97.6%, 93.2% and 78.2% at 3, 5, and 10 years after implantation, respectively. 12 patients (3.0%) experienced nonmechanical failure including infections, tissue erosion resulting in cylinder protrusion at the meatus and chronic discomfort. Overall survival rate of the penile prosthesis was 95.0%, 91.0% and 75.5% at 3, 5, and 10 years after implantation, respectively. Patients with neurogenic cause for ED showed lower median overall survival of penile prosthesis compared with patients with non-neurogenic cause. Patient age, obesity, and diabetes mellitus had no association with overall survival of penile prosthesis after implantation. CONCLUSIONS: The AMS 700CX/CXM could be accepted and applied in more patients as a reliable treatment alternative of ED.
