BACKGROUND: Loss of penile length after IPP implantation is a concern for many patients with ED who choose surgical treatment. The purpose of the study was to evaluate the effectiveness of the American Medical Systems (Minnetonka, MN, now Boston Scientific) 700™ LGX™ cylinders in maintaining penile length post-IPP implantation in patients treated for ED utilizing a modified method of cylinder sizing during implantation and a max-inflate technique after implantation. Success was defined as the distal length of a patient’s penis at 12 months post-implant being greater than the length of that patient’s penis at baseline pre-implant.
METHODS: A single armed, prospective, two-center study was conducted with patients selected from the existing population experiencing ED without previous prosthetic implantation. The patients were seen periodically between implant and the 24 month visit. The distal length of a patient’s penis at 12 months post-implant as measured using a paper ruler calibrated to the nearest 0.5 cm. Patient satisfaction was also captured on the Penile Prosthesis Patient Satisfaction Survey (PPPSS), and improvement in ED was measured using the International Index of Erectile Function (IIEF).
RESULTS: All patients were implanted using the penoscrotal approach. Twenty-six patients, with a mean age of 60.3 ± 7.7, were enrolled. Increases in the width and the circumferences were observed for all the subjects (22/22, 100%) at the 12 month visit. A decrease was seen in stretched penile length (12.5cm to 11.2c, p=0.0028). High or very high satisfaction was reported in 73% of the patients, 61.5% were satisfied with the length of their erection and 84.5% were satisfied with their ability to have intercourse. No surgical complications were reported.
CONCLUSIONS: The AMS LGX™ cylinders were able to maintain stretched penile length in 27.3% of patients with an increase in penile girth in 100% of patients. Defining a max-inflation protocol is essential for maintaining or increasing penile length. A scheduled max-inflation technique should be recommended to all patients soon after AMS LGX™ implantation to prevent loss of length.
