Objective: To investigate the clinical efficacy and patient and partner's satisfaction with penile prosthesis implantation (PPI) for treating Chinese patients with severe erectile dysfunction (SED).
Methods: One hundred and sixty-eight SED patients were successfully treated by PPI from July 2000 to June 2010. Of the 146 (86.9%) patients who had been followed up over 6 months post-operation, 36 (24.7%) had been implanted with one piece malleable prosthesis (AMS650) and 110 (75.3%) with three piece inflatable prosthesis (AMS700CXM).All the patients had been followed up by using international index of erectile dysfunction (IIEF5), Quality of Life Score (QOL) for evaluating clinical efficacy and using Visual Analogue Scale (VAS) for evaluating patient and partner's satisfaction and the duration of the follow-up was 6 to 119 months.
Results: The mean age of patients was 35.9+/-12.1 years(20 to 75 years), All the operations were successful and sexual intercourse with PPI was performed post 4 to 6 weeks without severe complications like infection and erosion. The prosthesis survive rate and frequent sexual intercourse rate were 98.6% and 87.7% respectively. IIEF5 scores pre and post PPI were 6.3+/- 1.7 and 21.3+/-1.6 respectively,the QOL scores pre and post PPI were 5.1+/-0.9 and 1.5+/-0.5 respectively, and both of them showed significant improvement (P<0.01). As for VAS, the patient and partner's overall satisfaction rates were 92.5% and 90.4% respectively. Moreover, better satisfaction was showed with AMS700CXM as compared with AMS650 (P<0.05) in patients with SED.
Conclusion: PPI is the safe and effective treatment option for Chinese patients with SED. The AMS700CXM penile prosthesis is better than AMS650 for patients' overall satisfaction.
