Penile prostheses are a well-established form of therapy for erectile
dysfunction. We report our experience with 333 cases using the Mentor
Alpha I inflatable penile prosthesis. With a follow-up period of 15.4
months, there were 25 (7.5%) complications with 15 (4.5%) major compli
cations that required reoperation. We also review the advantages and t
he procedures for implanting the penile prosthesis on an outpatient ba
sis or a one-day hospital stay.
