|
A single armed, prospective, two-center study was conducted with an aim of evaluating the effectiveness of the AMS 700 LGX cylinders in maintaining or increasing penile length postimplantation. The LGX has the unique ability to expand in length with inflation. Only 23.1% (6) of the patients were able to maintain stretched penile length. We now recommend leaving the implant inflated 60%–80% in the immediate postoperative setting for approximately 6 weeks. Then we teach pump training with deflation at around 6 weeks, prior to a maximum inflation protocol daily. Further studies would be required to validate if these interventions have significantly increased the number of patients who maintain or gain stretched penile length.
