Experience with AMS 700 LGX penile prostheses for preserving penile length in Korea.

Background: The purpose of this study was to report the outcomes of patients who underwent penile implantation with AMS 700 LGX inflatable penile prosthesis (IPP) in a single center by a single surgeon.
Methods: A total of 342 patients with erectile dysfunction who underwent AMS 700 LGX IPP implantation between October 2014 and April 2016 were included in this study. All patients were evaluated using the International Index of Erectile Function questionnaire preoperatively and at 3, 6, and 12 months postoperatively. We also investigated the mean stretched flaccid penile length before and after surgery as well as the complications related to and the mechanical reliability of the IPP.
Results: The questionnaire scores at 12 months were statistically significantly higher than the baseline scores. The mean stretched flaccid penile length was 11.1 ± 0.8 cm at baseline and was longer at 3 (11.9 ± 0.9 cm, P < 0.001), 6 (12.0 ± 0.9 cm, P < 0.001), and 12 (12.2 ± 0.7 cm, P < 0.001) postoperatively. There were no intraoperative or perioperative complications. However, one patient had infection and 10 patients developed mechanical failure during the follow-up duration.
Conclusions: The results of our study suggest that the AMS 700 LGX IPP could be used to prevent penile shortening in patients undergoing IPP implantation. Furthermore, erectile function and patient satisfaction were improved excellently.
