title: Mechanical reliability and safety of, and patient satisfaction with the Ambicor inflatable penile prosthesis: results of a 2 center study.
abstract: OBJECTIVE
  We reviewed the experience with the 2-piece Ambicor penile prosthesis (American Medical Systems, Minnetonka, Minnesota) at 2 medical centers to investigate its mechanical reliability and complication rates as well as patient and partner satisfaction with the device.
  
  
  METHODS
  From 1995 through 1999, 131 men underwent implantation of an Ambicor penile prosthesis at 2 medical centers. We performed a 3-part study consisting of a retrospective clinical record review, mailed patient and partner questionnaire, and mailed modified patient and partner Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire. Mean followup was 43.4 months (range 12 to 73).
  
  
  RESULTS
  All 131 men had a history consistent with an organic etiology of erectile dysfunction, including vascular disease in 62%, radical retropubic prostatectomy in 17%, Peyronie's disease in 15%, neophallus construction in 4% and radical pelvic surgery in 2%. Mean patient age was 56.8 years (range 22 to 76) at implantation. Overall there were complications in 10 cases (7.6%), including infection, hematoma and mechanical failure in 6 (4.6%), 1 (0.7%) and 3 (2.3%), respectively. A total of 112 men (85%) and 91 partners completed the questionnaire. All patient respondents still had an Ambicor prosthesis implanted and 96.4% had erection suitable for coitus. Overall patient and partner satisfaction was 96.4% and 91.2%, respectively. Of the respondents 92.9% of patients and 90.1% of partners would recommend the device to others. Of the 85 men (65%) and 46 partners who completed the modified Erectile Dysfunction Inventory of Treatment Satisfaction survey 90.6% and 82.6%, respectively, were satisfied or very satisfied overall with the penile prosthesis.
  
  
  CONCLUSIONS
  The Ambicor penile prosthesis is associated with a low complication rate and reliable mechanical function. High satisfaction was reported by patients and partners.
