The AMS Hydroflex penile prosthesis was implanted in 34 organic impotence patients between June 20, 1986 and Aug. 6, 1990. Patients ages ranged between 26 and 71 with an average of 50.5. The causes of impotences were; 17 cases of post-radical pelvic surgery, 7 cases of injury, 6 cases of diabetes and 4 of others. First evaluation was made after 12 weeks of implantation in terms of patient satisfaction with sexual intercourse and post operative complication. Sixteen patients (47.1%) were highly satisfied with intercourse, 13 (38.2%) satisfied with intercourse, 2 (5.9%) slightly dissatisfied even with successful intercourse, 1 (2.9%) with no improvement and 2 (5.9%) could not follow. Utility of the prosthesis, e.g. effectiveness and safety was; high utility in 20 (58.8%), good utility in 11 (32.4%), slight utility in 1 (2.9%), no favorable in 1 (2.9%) and no judgement in 1 (2.9%). The overall effectiveness and safety of the Hydroflex was demonstrated based on the above findings. Long term evaluation was made from the initial implantation of the device up to the termination of the trial with average of 19.2 months and was mentioned altogether.
