Abstract
The Hydroflex* penile prosthesis has been implanted in 100 patients with a 1 to 3 1/2-year followup. Patient dissatisfaction among the earlier implants was high due to inadequate girth and support during intercourse and difficulty with inflation and deflation of the device. As experience was gained in patient selection and sizing of the cylinders, patient satisfaction improved considerably. The mechanical reliability of this device has been good to date.
