Five-Year Followup of the Scott Inflatable Penile Prosthesis and Comparison with Semirigid Penile Prosthesis

The Scott inflatable penile prosthesis remains one of the most popular devices available for the surgical treatment of impotence despite high complication and reoperation rates. We present our 5-year followup of 116 inflatable prostheses placed before 1981 in 85 patients, with a 61 per cent overall 5-year complication rate. The incidence of complications by year after operation showed that most (22 per cent) devices failed within 1 year after implantation, with failure rates gradually decreasing to 6 and 7 per cent during years 4 and 5, respectively. Of 85 patients receiving an inflatable prosthesis 61 per cent underwent reoperation during the 5-year followup. A 5-year overall complication rate of only 14 per cent was seen in 29 Small-Carrion semirigid prostheses implanted during the same time. The results of numerous recent improvements in the design and structure of the Scott inflatable penile prosthesis to prevent mechanical device failure remain to be tested over the long term.
